Applying agricultural sheets to prevent weed growth as part of cultivating kōzo.
Mr. Fukunishi explaining about kōzo raw material.
Although a wide range of tools and raw materials are used in the preservation and restoration of cultural property, fine arts, and crafts, many are at risk of being discontinued in the future due to a lack of skilled successors and increasing difficulty in securing the necessary materials. In response to this situation, the Center for Conservation Science, Department of Intangible Cultural Heritage, and the Department of Art Research, Archives and Information Systems at the Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been involved in the commissioned research of “Investigation of Tools and Materials Used for the Preservation and Restoration of Fine Arts and Crafts” as part of the project of the Agency for Cultural Affairs, “Support for the Management of Tools and Materials Used for the Preservation and Restoration of Fine Arts and Crafts.” This report introduces a field survey of the cultivation of kozo (paper mulberry), the raw material for washi (Japanese paper), which is essential for the restoration of cultural property. It also presents the current use of wood ash in the cooking process used to obtain kozo fibers.
We visited four kozo fields in Yoshino Town and Gojo City, Nara Prefecture, on June 9-10, 2025, and learned about the meticulous work involved in tasks called mekaki (the removal of unnecessary new shoots and buds to concentrate nutrients on the remaining ones) and weed control, as well as the various innovations and challenges involved in the cultivation process. There is no end to the challenges, such as determining the cause of “red streaks” that appear on the inner bark, which reduce the usable amount of raw material because they discolor the fibers, and dealing with insects that were not seen in the past. The number of people responsible for this type of cultivation management is decreasing year by year, which poses a significant challenge in terms of ensuring a stable supply of this raw material.
We also visited the paper-making factories of Mr. FUKUNISHI Masayuki and Mr. UEKUBO Ryoji. The raw materials and wood ash are carefully selected and the delicate process of removing inclusions one-by-one by hand is repeated, because such inclusions make the material unsuitable for the restoration of cultural property. The issue of ensuring a stable supply of wood ash in the future was also discussed. An alkaline solution obtained from wood ash is essential for extracting kozo fibers, but it is also becoming increasingly difficult to procure the ash to obtain good quality fiber.
Going forward, we will conduct scientific research into the interactions between ash derived from various plant species and various raw materials and woods, with the aim of addressing specific challenges. In parallel, we will focus on strengthening our role as a network hub, connecting experts and knowledge across related fields, while continuing our ongoing efforts to document production techniques and processes.

People engaged in noriutsugi supplies intently listened to the explanation by Mr. Fukunishi
“Neri,” a substance extracted from noriutsugi trees, is essential for making Uda washi (Japanese traditional paper) that is used for cultural property restoration. Under the strong sunshine in early summer, people in Shibetsu Town, Hokkaido, carefully remove bark from noriutsugi and peel off its outer parts by hand to extract the inner parts. Furthermore, to reduce reliance on the wild species, they have begun to grow noriutsugi trees in nurseries.
Four members of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN), Mr. NISHIDA Noriyoshi, Head of Analytical Science Section, Center for Conservation Science, Ms. ICHIMIYA Yae, Associate Fellow of the same Center, Ms. MAEHARA Megumi, Head of Intangible Cultural Properties Section, the Department of Intangible Cultural Heritage, and Mr. ODAWARA Naoya, Associate Fellow of the same Department, visited Shibetsu Town from June 24 to 27, 2025. They inspected the process of barking noriutsugi and peeling off its outer parts, and video-recorded the way to grow nursery trees with talks provided by the related parties. They also participated in and video recorded dissemination activities, including a workshop by Mr. FUKUNISHI Masayuki, a holder of selected conservation techniques for handmade washi essential for mounting (Uda washi paper) held at the Shibetsu Town Culture Hall, targeting elementary school students and the wider public. These videos are planned for use in research, education, and dissemination related to the succession of cultural properties after editing.
TOBUNKEN concluded an agreement on collaboration and cooperation on materials for cultural property restoration with Shibetsu Town on November 2, 2023. Recording and disseminating the activities to ensure sustainable supplies of noriutsugi and dissemination activities are expected to benefit this collaboration and cooperation.
Measuring the outside diameter of common reeds (at Kurita Trading Co., Ltd.)
Common reeds grown to over three meters
The Department of Intangible Cultural Heritage is investigating the common reeds (Phragmites australis) used to make the rozetsu (reed) of hichiriki (Japanese traditional flute) as a part of a project to investigate the raw materials essential for intangible cultural properties. Accompanied by Ms. NAKAMURA Hitomi, a hichiriki player who also makes rozetsu by herself, we conducted a survey of common reed fields around Watarase-yusuichi (retarding basin) on June 16, 2025. Watarase-yusuichi, a Ramsar-designated wetland since July 2012, is one of the largest common reed fields in Japan, as 2,500 ha of the area is covered by various plants, around half of which comprises the common reed fields.
We started this investigation by visiting Kurita Trading Co., Ltd. We asked them to select thick common reeds suitable for the rozetsu of hichiriki and provide them to us as sample materials. We plan to request several rozetsu creators to use the samples to make rozetsu and assess the suitability of common reeds grown in Watarase-yusuichi for rozetsu.
The Council for Conservation and Utilization of Watarase-yusuichi was organized, consisting of local governments, representatives of local community associations, and related associations of four cities and two towns: Tochigi City, Oyama City, and Nogi Town, Tochigi Prefecture; Itakura Town, Gunma Prefecture; Koga City, Ibaraki Prefecture; and Kazo City, Saitama Prefecture. With the Ministry of Land, Infrastructure, Transport and Tourism and the Ministry of Environment as observers, the Council is seeking a future vision for Watarase-ryusuichi and submitting requests based on accumulated discussions on damage caused by animals and the means of water control, while conducting activities to raise awareness through the creation of a guidebook for learning about its environment.
Furthermore, as it is essential to burn common reeds every year to maintain the common reed bed in good condition, the related four cities and two towns, their related fire departments, the Joint Association of Watarase-yusuichi Utilization Unions, the Acclamation Promotion Foundation, and the River Management Office of Upper Tone River set up a Common Reed Burning Network, and conduct the burning of common reeds together.
While the demand for domestic common reeds is limited and the number of business operators utilizing common reeds and Amur silvergrass has decreased to five, the network of business operators, local governments, local community associations, and related associations, manages to maintain the common reed beds in Watarase-yusuichi, and makes continuous efforts to promote public awareness and wider understanding. We are continuing to investigate the characteristics of common reeds in Watarase-yusuichi, and to explore their usage, as some gagaku players believe that they are suitable for rozetsu of hichiriki.

Talk show featuring master HAYASHIYA Shojaku (right) and Mr. MIYA Nobuaki (left)
On May 23, 2025, a symposium entitled “Tokyo National Research Institute for Cultural Properties’ Recording Project for Performing Arts (Rakugo): Stories of Shohon Shibai Banashi by Master HAYASHIYA Shojaku” was held in the seminar room of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN).
The Department of Intangible Cultural Heritage has been conducting projects to record performances of intangible cultural properties, mainly classical performing arts, selecting genres and repertoires that are rarely performed in public. As part of this project, we have been recording live performances of the traditional Japanese stories called Shohon Shibai Banashi by master HAYASHIYA Shojaku since 2013, and now that the number of performances has reached sixty, we decided to hold a symposium to review the records of his performance works.
The symposium began with an opening remark and introduction given by Ms. MAEHARA Megumi, Head of the Intangible Cultural Properties Section, Department of Intangible Cultural Heritage, followed by a presentation by Mr. IJIMA Mitsuru, Visiting Researcher of TOBUNKEN, entitled “The Project to Record Performances of Shohon Shibai Banashi at the Tokyo National Research Institute for Cultural Properties,” and a presentation by Mr. MIYA Nobuaki, Associate Professor, Kyoto University of the Arts, entitled “The World of Shohon Shibai Banashi.” Next, the master HAYASHIYA Shojaku performed “Masakado” (without props) and ‘Suimon-mae’ (with props) from “Shinkei Kasanegafuchi,” and the event was recorded in front of the audience. In addition, in a discussion between master HAYASHIYA Shojaku and Mr. MIYA, master Shojaku shared stories of how he became attracted to and learned Shohon Shibai Banashi, as well as his thoughts on the future of Shohon Shibai Banashi. The event concluded with a closing remark by ISHIMURA Tomo, Director of the Department of Intangible Cultural Heritage.
These recordings of master HAYASHIYA Shojaku’s performances (Shohon Shibai Banashi) will soon be available to view (with a few exceptions) at the TOBUNKEN library. An announcement will be made on our website when these become available.
The Department of Intangible Cultural Heritage will continue to record classical performing arts that are rarely performed, and make them available to the public in an appropriate manner, in an effort to contribute to the preservation of intangible cultural properties.

In 2021, TOBUNKEN received a donation of paper-based documents (a total of 2,235 items) owned by OIKAWA Takeo (1942 – 2018). He was known as a collector of traditional Japanese musical instruments and related documents. The Department of Intangible Cultural Heritage has been organizing the donated documents and since 2022 has made a database of the documents open to the public on the TOBUNKEN website, as the OIKAWA Takao Collection. The collection covers a wide variety of paper-based documents, with varying formats and period of establishment, based on Japanese traditional musical instruments originating within and outside Japan.
These documents are available for viewing at the TOBUNKEN library by reservation. However, aiming to make these documents more widely available, the department has started to digitize the rare works and those in such condition that their handling is to be avoided. The documents that have already been digitized and are now available are listed in the “pdf” column in the database, available here (Japanese only). We are now continuing our work on digitizing the rest of the documents.
Mr. OIKAWA exhibited his musical instrument collection, which he had collected by himself, at the “Oikawa Museum of Musical Instruments”, and guided the visitors as the museum director from 2003-2015. He wanted visitors to handle these instruments and make sounds with them. Therefore, we believe that making his paper-based documents available to a wider audience follows his aspiration. We hope you will make use of the database.
Mr. TANAKA Naoichi
Mr. HIYOSHI Shogo
The Department of Intangible Cultural Heritage has been recording live performances of Heike (or Heike Biwa). Heike faces the crisis of not being inherited by the next generation because of the recent absence of sufficient successors. This series of recordings has been conducted with the cooperation of the Heike Narrative Research Society, led by Prof. KOMODA Haruko, Musashino Academia Musicae, and other members of the society, including Mr. KIKUO Yuji, Mr. TANAKA Naoichi, and Mr. HIYOSHI Shogo since 2018. The seventh recording session of “The Visit to Chikubushima” (the entire piece) and “the Uji River” (the first half of the piece) was held in the Tokyo Research Institute for Cultural Properties (TOBUNKEN) Performing Arts Studio on January 31, 2025.
In “The Visit of Chikubushima,” an episode of a fortunate omen is narrated. Taira no Tsunemasa, adjutant general of the Taira clan and also an excellent poet and singer, visited the Chikubushima (the island of Chikubu) by a small boat on his way heading north along Lake Biwa. In Chikubushima, when he played secret music on the biwa instrument that was handed to him, a white dragon appeared above his sleeve. As Benzaiten (Goddess Saraswati), who is also a deity of performing arts, is enshrined in Chikubushima, this story implies harmony with the biwa instrument. “Uji River” features the fight for the vanguard between Kajiwara Genta Kagesue and Sasaki Shiro Takatsuna of the army of Minamoto no Yoritomo on the way to chase Kiso no Yoshinaka. In the first half, the following two highlights were well expressed: Kagesue and Takatsuna escalated their competitive spirits, triggered by the event in which an excellent horse called Ikezuki was given to Takatsuna, though Kagesue had asked for it. This led to a rising of tensions in the Minamoto army and the Kiso no Yoshinaka army facing each other across the raging Uji River.
We recorded the live performances in which Mr. Kikuo and Mr. Tanaka played “The Visit of Chikubusima” (the entire piece) and Mr. Hiyoshi played “the Uji River” (the first half of the piece).
The Department will continue to archive the traditional and reconstructed pieces of “Heike” live performances by the Heike Narrative Research Society.

A scene from the rehearsal (Mr. FUJIMA Kiyotsugu (tachikata))
At the Department of Intangible Cultural Heritage, we are working to develop new methods for recording traditional performing arts. The “Free Viewpoint Video System” places cameras around the subject, records the subject’s movements from all directions, and allows the footage to be viewed from any angle. In theatrical genres such as classical performing arts, where a certain direction on stage is perceived as the front, the system makes it possible to analyze movements and postures at a certain point in time from various angles (for example, the side or back), which may lead to new approaches in the transmission of techniques and analytical research of performing arts.
On July 10, 2024, a performance was conducted with the cooperation of Mr. FUJIMA Kiyotsugu, a tachikata performer of the Fujima school of the Nihon-buyo, and was filmed with 16 cameras, showing a suodori dance (danced without costume or wig) of “Musume Dojoji” to focus on the body movements when using props. After filming, the footage was reviewed from various perspectives, and on December 18, 2024 and January 10, 2025, the performer Mr. FUJIMA Kiyotsugu, system developers from the Denkosha Co., Ltd., and researchers from our institute Mr. ISHIMURA Tomo, Director of the Department of Intangible Cultural Heritage, Ms. MAEHARA Megumi, Head of the Intangible Cultural Properties Section, Department of Intangible Cultural Heritage, and Ms. KAMATA Sayumi, Researcher of the Department of Intangible Cultural Heritage, exchanged opinions and provided feedback from their respective positions on the expected purposes of use, points to be aware of when using the system, operability, and desired functions. In addition, on January 11, 2025, the preliminary results of this research were orally presented at the second plenary meeting of the Grant-in-Aid for Scientific Research “Materia-Mind: Constructing a New Human Historical Science of the Co-creation of Material and Mind”* under the title “Performing arts and kinesiology: Analysis of the performer’s physical movements” by Mr. ISHIMURA.
We will continue working with performers and system developers to explore approaches that can serve as new recording and research tools for traditional performing arts.

On October 3, 2024, a symposium entitled “Tokyo National Research Institute for Cultural Properties’ Recording Project for Performing Arts (Kodan): In Memory of Master ICHIRYUSAI Teisui” was held in the seminar room of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN).
The Department of Intangible Cultural Heritage has been conducting projects to record performances of intangible cultural properties, mainly classical performing arts, selecting genres and repertoires that are rarely performed to the public. From 2002 to 2020, we have filmed and recorded 145 performances of kodan(storytelling) by ICHIRYUSAI Teisui (1939-2020), a holder of the Nationally Designated Important Intangible Cultural Property “Kodan” [individually certified].
The symposium began with an opening remark by Mr. ISHIMURA Tomo, director of the Department of Intangible Cultural Heritage, and then featured a lecture by Prof. IMAOKA Kentaro from the Musashino Art University, entitled “On the Establishment of the Kabuki Play ‘Kanjincho’ and its Relationship with Kodan.” There was also a screening a film of ‘Kimura Nagatonokami no Kannin Bukuro,’ an episode from “Nanba Senki,” performed by ICHIRYUSAI Teisui and recorded at the performing arts studio in the institute on May 26, 2015. Afterwards, Mr. ICHIRYUSAI Teikitsu, a disciple of ICHIRYUSAI Teisui, performed the play “Kanjincho,” followed by a talk show entitled “About Master ICHIRYUSAI Teisui,” featuring Mr. ICHIRYUSAI Teikitsu and Mr. IJIMA Mitsuru, a visiting researcher of TOBUNKEN.
These recordings of ICHIRYUSAI Teisui’s performances will soon be available to view (with a few exceptions) at the TOBUNKEN library. An announcement will be made on our website when these become available.
The Department of Intangible Cultural Heritage will continue to record classical performing arts that are rarely performed, and make them available to the public in an appropriate manner, in an effort to contribute to the preservation of intangible cultural properties.
A demonstration at the Symposium
Exhibitions
On August 9, 2024, a symposium entitled “‘Wisdom and Techniques’ Nurtured with Forests: For the Future of Intangible Cultural Heritage” was held at the Tokyo National Research Institute for Cultural Properties (TOBUNKEN).
The recent difficulty in obtaining raw materials to support intangible arts and techniques for repairing tangible cultural properties has become a major problem. There are various reasons for this: the mountains are no longer cared for and thus suitable timber is no longer available, timber producers have withdrawn due to decreased demand, the distribution system has collapsed, etc. All of these factors are due to the fact that the relationship between people and Nature has changed.
The purpose of this symposium was to make the current situation widely known and to build a network for thinking together about how to solve these problems. In the first part of the symposium, five people were invited to demonstrate various techniques using natural materials. Ms. ARAI Eriko demonstrated making a “Ohara basket” from Itaya maple and Mountain maple, Ms. NOBUHARA Yuki wove a “Omogishi-mi (winnowing basket)” from the bark of Bakkoyanagi (Salix caprea) and the core of Sarunashi (Actinidia arguta), Ms. NAKAMURA Hitomi made “Hichiriki reeds” from Yoshi (reed), Mr. KOJIMA Shusuke made a “Kiri box” of Paulownia, and Mr. SEKITA Tetsuya carved a “Kezurikake,” a ritual tool, from wood from the Satoyama landscape; and all of these presenters freely interacted with the participants while providing information and explanations. The second part of the event was followed by a lecture by Dr. MAKITA Akifumi, Vice President of Akita Prefectural University, on “Nature as a Foundation of Culture,” and reports provided by three staff members of TOBUNKEN.
As mentioned earlier, a major factor behind the shortage of raw materials is the changing relationship between people and Nature. This is directly linked to changes in society as a whole, and it is not a problem that can be solved overnight. However, this is precisely why it is important to make society at large aware of this current situation, and to encourage people from various regions and standpoints to think about this issue and take action. The Department of Intangible Cultural Heritage will continue to conduct related research and networking activities to contribute to the resolution of this issue.
A full report on the symposium will be published soon, and a PDF version will be available on the website of the Department of Intangible Cultural Heritage.
Common reed to use for rosetsu of hichiriki
Common reed tied into batches.
The Department of Intangible Cultural Heritage (hereafter, “the Department”) is conducting investigations and research into the tools (e.g., musical instruments including their parts, stage properties, and costumes,) and raw materials that are essential for intangible cultural properties.
Common reed (Phragmites Australis) grown on a riverbed in the Kanmaki and Udono areas of Takatsuki City, Osaka Prefecture, has been known to be suitable for the rozetsu (mouthpiece) of hichiriki, a traditional Japanese flute used in gagaku, classical Japanese court music. Though it is necessary to annually burn the riverbed to maintain a suitable environment for common reed growth, the burning could not be done for two consecutive years due to unsuitable weather conditions and the COVID-19 pandemic. This resulted in an overgrowth of wild vines, which forced the common reed to almost disappear from the area by around September 2021.
To improve the situation, the Udono Association for Common Reed Riverbeds Preservation and Kanmaki Working Union cooperated with local residents, Takatsuki City administrative staff, parties interested in gagaku, and others to regularly burn the riverbed and remove vines. The Department has been investigating the growing environment and characteristics of the common reed in the areas. As a part of our investigation, we joined in the cutting of common reeds on February 2 and 3, 2024, and collected information about the current situation regarding the common reed and its usage. This public occasion was planned to cut the thin common reed not suitable for rozetsu to produce other products such as paper and towels made of common reed, after the Kanmaki Working Union cut the common reed suitable for rozetsu of hichiriki. Enterprises trying to expand the demand for common reed and individuals and groups trying to understand the natural environment of common reed fields also gathered on those two days. More than 60 people worked each day. This year the condition of the common reed in the area was better than last year, but the supply yield was not sufficient to meet the demand for rozetsu.
It is essential for succeeding gagaku that local people and enterprises better understand the common reed itself and that involved parties interested in gagaku gain a better understanding of common reed as a raw material of rozetsu for hichiriki.
The Department is continuing its investigation of the characteristics of common reed itself and its suitability for rosetsu for hichiriki. Furthermore, we are carefully monitoring the local environment where the raw materials grow.
Mr. HIYOSHI Shogo
Staff responsible for recording techniques
The Department of Intangible Cultural Heritage has been recording live performances of the instrument “Heike” or “Heike Biwa,” which faces the crisis of not being inherited by the next generation because of the recent absence of sufficient successors. This series of recordings has been conducted since 2018 with the cooperation of the Heike Narrative Research Society, led by Prof. KOMODA Haruko, Musashino Academia Musicae, and other members of the society, including Mr. KIKUO Yuji, Mr. TANAKA Naoichi, and Mr. HIYOSHI Shogo.
The sixth recording session of the performance of ‘Suzuki’ (Japanese sea bass) was held in the Tokyo National Research Institute for Cultural Properties (TOBUNKEN) Performing Arts Studio on February 8, 2024. In the ‘Suzuki’, an episode in which Japanese sea bass jumps into the boat of Taira no Kiyomori is narrated as a harbinger of the prosperity of the Heike clan under the patronage of Kumano Gongen. Because of its lyrics, ‘Suzuki’ is a favorite celebratory piece. The piece is also often used as an instructional (introductory) piece, as it contains a short but basic set of melodic patterns. For this recording of live performances, Mr. KIKUO, Mr. HIYOSHI, and Mr. TANAKA shared the performance, and the session was recorded.
This recording was assisted by students studying studio recording techniques under Prof. KAMEKAWA Toru, Tokyo University of the Arts, and thereby provided an opportunity to put into practice the sound techniques essential to the recording live performances. The Department of Intangible Cultural Heritage will continue to record live performances, refining the skills involved in recording traditional performing arts with like-minded people.
Published video (from left, Mss. MIAYAZONO Senyoshie, Senroku, Senkazuya, and Senkoju)
Miyazono bushi is one of Japan’s Important Intangible Cultural Properties; however, it is not often performed these days. Therefore, the Department of Intangible Cultural Heritage (hereafter, “the Department) has been recording its live performances since 2018. Recently, we published the opening parts of these video recordings on the TOBUNKEN homepage (https://www.tobunken.go.jp/ich/video/).
The original recordings of the Miyazono bushi were performed by Mss. MIYAZONO Senroku and Senkazuya both are individuals certified as Holders of Important Intangible Cultural Property, so-called “living national treasures.” The whole traditional pieces were recorded and archived in full. The full versions are available at video booths at the TOBUNKEN Library. Due to the limited number of booths, contacting us regarding availability beforehand is highly recommended. A guide to the library is available here.
The Department plans to publish as much more audio and video recordings as possible.

The eighteenth session of the Intergovernmental Committee for the Safeguarding of Intangible Cultural Heritage took place in Kasane, Republic of Botswana, from December 5 to 8, 2023. Two researchers from the Tokyo National Research Institute for Cultural Properties (TOBUNKEN), Ms. MAEHARA Megumi (Department of Intangible Cultural Heritage) and Ms. FUTAGAMI Yoko (Department of Art Research, Archives and Information Systems), attended the session. The Republic of Botswana is located in the northern area of the Republic of South Africa. Kasane is known as the northern gateway to Chobe National Park, and is a small town rich in nature and home to many wild animals. The venue was a temporary pavilion built for this meeting, and the atmosphere was idyllic, with a family of warthogs and their offspring grazing outside. As if in harmony with this peaceful atmosphere, the agenda proceeded peacefully under the chairmanship of H.E. Mr. Mustaq Moorad, Ambassador of the Delegation to UNESCO (Republic of Botswana), who often lightened the atmosphere with his humor.
This committee decided to inscribe six elements on the List of Intangible Cultural Heritage in Need of Urgent Safeguarding (Urgent Safeguarding List) plus 45 elements on the Representative List of Intangible Cultural Heritage of Humanity (Representative List), and to select four programs as the Programmes, The Evaluation Body, made recommendations to the committee, and recommended the inscription and selection of all of these elements and programs, which also greatly contributed to creating a peaceful atmosphere at the venue. Ms. FUTAGAMI will report on the details in the forthcoming “Research and Reports on Intangible Cultural Heritage” volume 18, to be published in March 2024; however, below we mention three impressions that we felt through the meeting.
First, many elements were nominated as multi-national nominations by multiple State Parties. Although the State Party of Japan has not yet had the experience of multi-national nomination, 12 of the 45 elements decided to be inscribed on the Representative List were multinational nominations. This trend has been noticeable for the past few years and is likely to continue.
Second, a common trend was observed in the videos shown at the meeting. Once the committee decided to inscribe an element, a short video introducing the element of intangible cultural heritage was often shown on the screen at the front of the venue, and many of these videos included the implications for Sustainable Development Goals (SDGs). In particular, keywords such as “gender,” “education,” and “marine and terrestrial resources,” were shown in the video story, and it was emphasized that intangible cultural heritage is built on SDGs efforts, or inheritance of intangible cultural heritage is directly linked to SDGs initiatives.
Third, we experienced the real thrill of side events. A number of small pavilions were temporarily erected adjacent to the venue, where a cultural aspect of each country was showcased and reports on safeguarding activities were made. Dance and musical performances, craft technology demonstrations and workshops, and activities of related NGOs were also presented. Intergovernmental Committees are attended by people who are highly interested in intangible cultural heritage from all over the world, not only from the committee member countries, but also from cultural property administrations, research institutes, and NGOs. Side events are very effective in appealing to their interests.
We felt that while the Intergovernmental Committee meeting was important for establishing international cooperation and assistance for safeguarding intangible cultural heritage, it was also a good opportunity to understand how each country views intangible cultural heritage.

The 17th Public Lecture Held by the Department of Intangible Cultural Heritage: Exploring the Charms of Miyazono-bushi was held on November 22, 2023 in the seminar room and the lobby on the first basement floor of TOBUNKEN.
The first half of the lecture began with an explanation of the purpose of this lecture by Ms. MAEHARA Megumi, the head of Intangible Cultural Properties Section, Department of Intangible Cultural Heritage. Presentations were then conducted with audio and video documentations by Mr. FURUKAWA Ryota (doctoral student, the University of Tokyo); Ms. HANDO Aya (Shokei-kan, Historical Materials Hall for the Wounded and Sick Retired Soldiers); Mr. IIJIMA Mitsuru, Senior Fellow of the Department, Dr. KAMATA Sayumi, Researcher of the Department of Intangible Cultural Heritage, and Ms. MAEHARA.
In the latter half of the lecture, a round-table-talk titled Talk with Ms. MIYAZONO Senroku and Ms. MIYAZONO Senkazuya was held. Both are individuals certified as Holders of Important Intangible Cultural Property. Ms. MIYAZONO Senroku and Ms. MIYAZONO Senkazuya talked about the characteristics of Miyazono bushi, and presented some episodes on how to learn it, and about the relationship of this genre with other types of hogaku (Japanese traditional music) genres. In addition, they answered pre-submitted questions from the participants. After that, an excerpt from the Live Performance recording of Miyazono bushi play, “Yugiri” was screened.
In this lecture, several attempts were made to help the audience to understand Miyazono-bushi from several perspectives: through hands-on experience of Miyazono bushi Shamisen; a short explanation by Mr. TAKEUCHI Yasuo, shamisen craftsman; a small exhibition of materials and musical instruments borrowed from General Incorporated Foundations Kokyoku-kai, Ms. MIYAZONO Senroku, and Ms. MIYAZONO Senkazuya, and related materials owned by TOBUNKEN; and a poster exhibition of the Live Performance recordings of Miyazono bushi, which TOBUNKEN is currently working on.
A questionnaire survey conducted after the lecture made us realize that this lecture became a meeting point for the traditional performing arts, based on answers such as “it is the first time to know TOBUNKEN,” and “it is the first time to listen to Miyazono bushi.”
We at the Department will continue our efforts to spread the charms of intangible cultural properties with the latest research outcomes. An edited video recording of this lecture will be broadcasted during a limited period. A report will be published both in paper and digital (pdf) formats in FY 2024, including each presentation and material introduction.
Preparation for the live recording.

On October 31, 2023, the Department of Intangible Cultural Heritage conducted the ninth recording of Miyazono-bushi at the Performing Arts Studio of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN).
Miyazono-bushi, one of the Important Intangible Cultural Properties of Japan, originated in the Kamigata (Kyoto-Osaka) area in the mid-Edo period and has since been handed down mainly in the Edo area. Today, Miyazono-bushi is collectively referred to as ‘kokyoku’ (lit. old music) along with other voice genres Icchū-bushi, Katō-bushi, and Ogie-bushi, and there are not many opportunities to hear it performed. The department has continued our attempts to record the live performances of Miyazono-bushi since 2018, archiving the target pieces in their entirety, without omission.
For this recording, two of the ten pieces in the Miyazono-bushi repertoire classified as ‘modern pieces’ were selected: “Sonoo no Haru” (Garden Spring) and “Wankyū.” The former was composed in 1888 to commemorate the official recognition of the Miyazono-bushi genre by the Meiji Government in 1884 and includes flamboyant kaede (another melody played in coordination with the basic melody) in the shamisen part, which is unusual for Miyazono-bushi compositions. The latter is a more recent work, composed in 1949. It tells the tragic love story between Wanya Kyūbē (also known as ‘Wankyū’), a wealthy merchant in the Osaka Shinmachi area, and Matsuyama, a courtesan in Shinmachi, and depicts a scene in which Wankyū falls into insanity. The roles were performed by MIYAZONO Senroku (lead jōruri voice performer: an individual certified as a Holder of Important Intangible Cultural Property or what is called a “Living National Treasure”), MIYAZONO Senyoshie (supporting jōruri voice performer), MIYAZONO Senkazuya (lead shamisen player: an individual certified as a Holder of Important Intangible Cultural Property, commonly called a “Living National Treasure”), and MIYAZONO Senkoju (supporting shamisen player).
The Department of Intangible Cultural Heritage will continue to make live recordings of classical and rarely performed modern pieces of Miyazono-bushi.
Tapping lacquer in South Korea
A Daegeum in which red lacquer was applied to the inside
With the cooperation of the National Intangible Heritage Center in the Republic of Korea, the Department of Intangible Cultural Heritage and the Center for Conservation Science of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN) jointly investigated the current situation regarding procurement of bamboo materials and urushi lacquer used to adjust the inner diameter of Japanese traditional wind instruments, and the succession of related techniques that developed in the Republic of Korea, where bamboo is used for their traditional wind instruments as in Japan.
In this investigation, we learned that bamboo logging associated with the development of residential and commercial lands is popular in Korea. Therefore, the general bamboo materials are in plentiful supply. On the other hand, the supply of some special bamboo materials such as ssanggoljuk (double-groove bamboo) used for daegeum, a traditional Korean bamboo flute, is unstable. Therefore, the Research Institute for Musical Instruments of the National Gugak Center developed a new material made by flatting bamboo to thin plates and bonding them under pressure, obtained a patent, and made this technique public. However, this new material is not yet widespread among instrument manufacturers or daegeum players. We understand the challenges involved.
Regarding urushi lacquer, we were impressed that the workers involved are well-protected to increase domestic production and demand for urushi lacquer liquids to change the current situation that many lacquer liquids are imported from China. We understand that the challenges related to the tools and materials used to restore the urushi lacquer products are not as severe in Korea as in Japan. For example, people we interviewed said that in Korea there are more than ten shops that process and sell mother-of-pearl shells, which are especially used for decoration.
In Korea, it is not popular to apply lacquer to wind instruments at present. However, red lacquer was applied inside of daegeum in the past. Even now, red lacquer is sometimes applied for decoration. We wonder about the original reason why the red lacquer was applied in the past.
In Japan, multiple lacquer layers of urushi lacquer are applied inside of the wind instruments to adjust their inner size. In Korea, the inner size is adjusted by shaving the inside of the bamboo, which has thicker and denser walls. These very different techniques provide an interesting contrast.
We will continue our investigation to find solutions to the challenges by comparing the challenges in Japan to secure the raw materials and success of the conservation techniques implemented in other countries that use the common raw materials, and by understanding the characteristics of each technique.
Checking the captured CT images.
Setting up to scan the koto, which is over 170 cm in length, was a challenge.
The Department of Intangible Cultural Heritage conducts research not only on the traditional performing arts themselves, but also on their ‘tools’ – musical instruments. The department has now started a joint survey of the structure of a koto (in a private collection), which is thought to have been made between the late Edo period and the Taisho period, in collaboration with two organisations: the Society for the Conservation of Traditional Japanese Musical Instrument Making Skills, which is a conservation group for the Selected Conservation Techniques of the making of the koto and the fashioning of the shamisen neck and body, and Kyushu National Museum, which belongs to the National Institutes for Cultural Heritage, in common with us. This effort is an attempt to synthesise the knowledge and perspectives that have connected performers and audiences through instrument-making skills, the techniques and perspectives of museology for non-destructive investigation of the interior of cultural properties, and the perspectives of instrumentology and musicology on intangible cultural properties to clarify the structure of the koto from multiple perspectives.
On August 29, a CT examination of the koto was conducted at the Kyushu National Museum, and while checking the images immediately after the scan, several discoveries unique to this collaboration were made. For example, opinions were exchanged on a newly discovered notch on the inner bottom surface of the koto: the notch appears to have been accidentally caused by the entry of a saw blade once used in the instrument-making process and to have been partially filled in with other wood to compensate for this.
This research has only just begun, but by gathering opinions from people with various perspectives, it is hoped that new aspects will emerge, such as the techniques used in the instrument-making process, the intentions of the makers, and the structure of the koto as the culmination of this work. In the future, we intend to examine the CT images obtained in detail, scrutinise the origin of this koto, and compare it with other kotos owned by other institutions that may have been made by the same maker, to clarify the characteristics of its structure and production techniques.
Common reed field at the mouth of the Kitakami River selected for 100 Soundscapes of Japan: Preserving our Heritage (Agency of the Environment (at that time) 1996)
The Department of Intangible Cultural Heritage investigates the common reeds (Phragmites australis) used for a rozetsu (reed) of hichiriki (Japanese traditional flute) as a part of a project to investigate the raw materials essential for intangible cultural properties. We conducted a survey of common reeds growing around the mouth of the Kitakami River in Ishinomaki City, Miyagi Prefecture, where such reeds are produced. We had two goals for this survey: the first was to assess the suitability of the common reeds in this area for rozetsu of hichiriki by analyzing their characteristics; the second was to find ways to “restore common reeds” in the riverbeds of the Yodo River (Osaka Prefecture), which is known as a production field of the common reeds suitable for rozetsu of hichiriki, by understanding the common reed restoration process and the present conditions of the Kitakami River area, which was severely damaged by the Great East Japan Earthquake in 2011.
We visited Kumagaya Master Thatchers Co., Ltd., which is working on restoring the common reed field in the Kitakami River area. We interviewed them, about the current common reed field situation and were given samples of common reeds with external diameters large enough to make rozetsu. Kumagaya Master Thatchers thatches roofs of temples, shrines, and other traditional Japanese architecture using traditional techniques and also works on the conservation and restoration of Important Cultural Properties designated by the Japanese government.
We requested two craft persons to make rozetsu from the common reed samples of the Kitakami River that we were given. We plan to compile findings, including evaluations by hichiriki players on the rozetsu made from those common reeds.
We also visited the Kitakamigawa-karyu River Office of the Infrastructure and Transport Tohoku Regional Bureau, the Ministry of Land, which manages the Kitakami River, and Prof. YAMADA Kazuhiro of Tohoku Institute of Technology, is investigating the common reed field before and after the Earthquake and is active in promoting the field. Though the reed field was approximately 183 ha before the Earthquake, it has since shrunken to approximately 87 ha. The field has sunken by 50 to 60 cm and was flooded in the aftermath of the earthquake. Therefore, many common reeds withered and died, and growth of the rest was inhibited by debris brought by the tsunami.
The debris has since been removed thanks to local cooperation, and the reeds have been replanted as an experiment to restore the field. We appreciate the understanding and cooperation of locals who supported the nature revival in the process of the natural environment recovery from the damage by the natural disaster.
Furthermore, a framework was set for conserving the river and surrounding environment through information exchange and reporting by the Kitakamigawa-karyu River Office and other three cooperative organizations backed by the River Cooperation System set in the Act for Partial Revision of the Flood Prevention Act and the River Act (June 2013). We understand that these cooperations contribute to restructuring the common reed field.
Researchers of the Department of Intangible Cultural Heritage, respectively specialized in intangible cultural properties, folk cultural properties, and cultural heritage disaster risk management, work together to comprehensively investigate the situations, challenges, and solutions in regard to the people, techniques, and materials essential to inheriting intangible cultural properties.
The Department of Intangible Cultural Heritage has been recording live performances of Heike or Heike Biwa. However, this tradition faces the crisis of not being inherited by the next generation because of the recent absence of sufficient successors. This series of recordings has been conducted with the cooperation of the Heike Narrative Research Society, led by Prof. KOMODA Haruko, Musashino Academia Musicae, and other members of the society, including Mr. KIKUO Yuji, Mr. TANAKA Naoichi, and Mr. HIYOSHI Shogo since 2018. The fifth recording session of the performance of Nasu no Yoichi and Ujigawa (Uji River) was held in the TOBUNKEN Performing Arts Studio on February 3rd, 2023.
Nasu no Yoichi is famous for the episode where Nasu no Yoichi shot down the targeted fan with his arrow, and he was praised and credited by Minamoto no Yoritomo. This scene has also been repeatedly painted. Therefore, working with the National Center for the Promotion of Cultural Properties (CPCP) of the National Institutes for Cultural Heritage, which promotes the utilization of high-resolution reproduction of cultural properties, we recorded live performance that was set with the high-resolution reproduction folding screen of the Battles of Ichi-no-tani and Yashima, from the Tale of the Heike behind the player. This was our first trial. The Ujigawa episode has the theme of a majestic fight for the vanguard in front of the Uji River between Sasaki Takatsuna and Kajiwara Kagesue. We recorded the performance of Nasu no Yoichi. The first part and the last parts were performed by Mr. KIKUO and Mr. HIYOSHI, respectively, while Ujigawa was performed by Mr. TANAKA.
Heike started as a traditional performing art at the beginning and was transformed into the Tale of the Heike as literature and further developed into other genres, including paintings. We intend to explore new ways to spread awareness about Heike as an art form that has been represented in various cultural mediums presenting the same theme.

Roundtable discussion (from right: Mr. SAKURAI Hiroshi, Mr. NUNOME Aito, Mr. EZOE Junichiro, and Mr. NAKAMINE Miki)
The Department of Intangible Cultural Heritage held Forum 4: Traditional Performing Arts amid COVID-19 Pandemic: Dissemination and Succession for the Future on November 25th, 2022.
First, ISHIMURA Tomo, MAEHARA Megumi, and KAMATA Sayumi of the department presented international case studies regarding traditional performing arts and education, the current status of traditional performing arts amid the COVID-19 pandemic, and last year’s progress in Japan.
Following three presentations, Mr. SAKURAI Hiroshi (from Independent Administrative Agency, Japan Arts Council), Mr. NUNOME Aito (from Public Interest Incorporated Association, Geidankyo, Japan Council of Performers Rights and Performing Arts Organization), Mr. EZOE Junichiro (from Toppan Inc., Secretariat of Dissemination and Empowerment for Hogaku of the Agency for Cultural Affairs), and Mr. NAKAMINE Miki (from Association of Okinawa Sanshin Manufacturing) reported their respective case studies, in which they tackled the topic of dissemination and succession of traditional performing arts from different positions and frameworks. Between case reports, Mr. OKAMURA Shintaro and Ms. OKAMURA Ai—who teach Japanese traditional music to the schools selected for the Dissemination and Empowerment of Hogaku, by the Agency for Cultural Affairs—performed jiuta sangen, a type of Japanese traditional music played on the shamisen, Kurokami (black hair), and Hashizukushi (bridges).
The roundtable discussion was held by four case study reporters, in addition to ISHIMURA and MAEHARA. Through this roundtable discussion, we shared the dissemination and transmission of traditional performing arts from different positions. Moreover, it revealed that the challenges of increasing demand were inherent even before the pandemic, and that it became increasingly apparent during COVID-19. Furthermore, based on the common understanding that dissemination is the basic foundation for the succession of traditional performing arts, we recommended the following steps to seamlessly disseminate traditional performing arts: meet the needs of various ages from various positions and by various frameworks; and grasp a variety of demands by sharing this information among the people who work on the dissemination and succession of traditional performing arts.
This forum was held with limited seats to prevent the transmission of COVID-19. The recorded video is now available for free on the TOBUNKEN webpage （https://www.tobunken.go.jp/ich/vscovid19/forum_4/） in Japanese till March 31st, 2023. We plan to publish a report and make it available on our website by the end of this fiscal year.
