A study of selected conservation techniques in the Village of Showa, Fukushima Prefecture: The second research exchange with the National Research Institute of Cultural Heritage, South Korea

Burning off brush to prepare fields to grow ramie

 Following events in April, Mr. Chae Won LEE of South Korea’s National Research Institute of Cultural Heritage visited Japan as part of Research Exchanges between Japan and South Korea in relation to the Safeguarding and Preservation of Intangible Cultural Heritage. Mr. LEE studied selected conservation techniques, which are techniques for conservation of cultural properties. The Village of Showa, Fukushima Prefecture grows ramie (Boehmeria nivea) and extracts its fiber to supply the material to make Ojiya crepe and Echigo linen, which are important intangible cultural properties. The study coincided with karamushi-yaki, or burning off of brush to prepare fields to grow ramie during shoman (the 8th of 24 solar terms in the traditional Japanese calendar when crops ripen/bloom around May 21st or so). This coincidence allowed Mr. LEE to see an important growing process firsthand. In addition, group interviews regarding ramie were conducted to hear the perspectives of administrators and conservators and the perspectives of others, facilitating a more extensive discussion of the significance of ramie growing to the Village of Showa and systems to conserve selected conservation techniques. Results of the research exchanges, which lasted 2 weeks, were presented at a seminar that highlighted differences in Japanese and Korean perceptions of Selected Conservation Techniques (no such framework exists in South Korea). The seminar also highlighted ways to safeguard cultural properties.

2013 Japanese-Korean seminar held

Joint survey in Fugoppe Cave

 The Center for Conservation Science and Restoration Techniques has studied the conservation of cultural properties outdoors as part of Research on the Effects of Environmental Pollution on Cultural Properties and the Development of Restoration Techniques. This international research project has been conducted jointly with the National Research Institute of Cultural Heritage, South Korea. As part of the project, seminars are held annually by both institutions so that researchers from both countries can interact more closely with their counterparts. 
 This year, a seminar was held on May 21 (Tues.) in a basement meeting room at the National Research Institute for Cultural Properties, Tokyo. Presentations were given by 4 personnel from the National Research Institute of Cultural Heritage, South Korea: Sa Dug KIM, Sun Myung LEE, Tae Jong LEE, and Yu Gun CHUN. Presentations were also given by KUCHITSU Nobuaki, NAKAYAMA Shunsuke , and MORII Masayuki of the National Research Institute for Cultural Properties, Tokyo. The conservation of cultural properties outdoors was discussed. The following day, a joint survey was conducted in Hokkaido. The status of the display and conservation of petroglyphs in the Fugoppe Cave (Town of Yoichi) and Temiya Cave (City of Otaru) was studied. Conservation of the Bangudae Petroglyphs in Ulsan is a current topic in South Korea. Korean researchers asked numerous questions about topics such as display lighting and facilities maintenance. The conservation of petroglyphs in Japan proved informative.

KURODA Seiki in Formal Attire (Photo: OGAWA Kazumasa, July 1914, in the collection of the National Research Institute for Cultural Properties, Tokyo [donated by KANEKO Mitsuo])

 The Department of Art Research, Archives, and Information Systems held its first seminar of 2013 on April 30. Research presentations were given on Hananokage (Illustrious Portraits), a Private Photography Magazine for Nobles, and Letters from OGAWA Kazumasa to KURODA Seiki. Presentations were made by SAITO Yoichi (Tojo Historical Museum, City of Matsudo) and OKATSUKA Akiko (Edo-Tokyo Museum, Tokyo) along with TANAKA Atsushi.
 Starting off, Mr. SAITO described results of his previous studies of Hananokage (published from 1903 to around 1908), a private photography magazine published by former daimyo (feudal lords) such as TOKUGAWA Yoshinobu and TOKUGAWA Akitake, i.e. Meiji-era nobles. Based on his studies, Mr. SAITO deduced that 4 volumes of Hananokage were published each year. Mr. SAITO focused on 5 editions published between March 1907 and March of the following year that featured Photography Critiques of submitted photographs authored by KURODA Seiki and photographer OGAWA Kazumasa (1860–1929). Based on these Photography Critiques, Mr. TANAKA appraised KURODA as an artist and OGAWA as a photographer, and Mr. TANAKA also described KURODA’s views on “photography.” Letters addressed to KURODA Seiki curated by the Institute include letters (7) from OGAWA Kazumasa. Ms. OKATSUKA is studying OGAWA based on these letters, and she described the relationship between KURODA and OGAWA. She also described the world of Meiji photography based on OGAWA’s relationship to nobles of the period. Plans are to publish the results of this research in vol. 411 of Bijutsu Kenkyu (The Journal of Art Studies) (scheduled for publication in Nov. 2013) and in subsequent volumes.

A study of Yuki-tsumugi (silk fabric from Yuki): The second research exchange with the National Research Institute of Cultural Heritage, South Korea

the Omoigawazakura workshop

 This year marks the second year of Research Exchanges between Japan and South Korea in relation to the Safeguarding and Preservation of Intangible Cultural Heritage. The Department of Intangible Cultural Heritage conducted exchanges with South Korea’s National Research Institute of Cultural Heritage. In April, researcher Ms. Gyeong Soon HWANG of South Korea’s National Research Institute of Cultural Heritage visited Japan, where she studied Yuki-tsumugi in Ibaraki and Tochigi Prefectures. Since Yuki-tsumugi was inscribed on UNESCO’s 2010 Representative List of the Intangible Cultural Heritage of Humanity (Representative List), efforts have made to conserve the technique through culture, industry, and tourism. The study of Yuki-tsumugi included group interviews with conservators, administrators, and other personnel, and the study also enhanced discussion of the basis for preserving Yuki-tsumugi. Results of the research exchanges, which lasted 2 weeks, were presented at a seminar. The seminar highlighted differences in Japanese and Korean policies regarding and views of intangible cultural heritage.

Front cover of “YOKOYAMA Taikan’s Yamaji”
Display boards on Research on YOKOYAMA Taikan's Yamaji in the Institute’s entrance lobby

 This spring, the Department of Art Research, Archives, and Information Systems published volume 6 of the Archive of Art Studies, entitled “YOKOYAMA Taikan’s Yamaji.” The Department of Art Research, Archives, and Information Systems started publishing the Archive of Art Studies in 2002. This volume summarizes the results of 3 years of research on YOKOYAMA Taikan’s Yamaji conducted jointly with Eisei Bunko. In the past, individual research reports were made available via the Institute’s website, but the full nature of that research has now been revealed to the public thanks to the cooperation of a number of individuals.
 Vol. 6 of the Archive of Art Studies features Yamaji (painted in 1911) in Eisei Bunko’s collection and a variant of that piece, Yamaji (painted in 1912), in the collection of the National Museum of Modern Art, Kyoto. This volume assembles information on the individual pieces based on their restoration and analysis of the pigments used as well as textual information regarding the pieces, such as critiques when they were presented and a description of their provenance. Reliable articles based on surveys of the pieces and other materials have been authored by ARAI Kei (Tokyo University of the Arts), OGAWA Ayako (Tokyo National Museum), SATO Shino (Yokoyama Taikan Memorial Hall), TAIRA Yuichiro (Tokyo University of the Arts), TAKEGAMI Yukihiro (Association for Conservation of National Treasures), NOJI Koichiro (Nerima Art Museum), HAYASHIDA Ryuta (Kumamoto Prefectural Museum of Arts), MIYAKE Hidekazu (Eisei Bunko), and SHIOYA Jun, who were involved in restoring and studying the pieces. Hopes are that this case study of research on a single work will, like previous volumes of the Archive of Art Studies, contribute to future studies of art history. Vol. 6 is available from Chuo Koron Bijutsu Shuppan. Please see the website below for details.
 http://www.chukobi.co.jp/products/detail.php?product_id=635.
 In conjunction with the publication of this volume, display boards describing Research on YOKOYAMA Taikan’s Yamaji were exhibited in the entrance lobby on the first floor of Institute starting on March 28. The display boards provide an overview of the research with a focus on images of Yamaji in Eisei Bunko’s collection (the same images are featured in Vol. 6). Thanks to high-resolution images taken by SHIRONO Seiji of the Institute, visitors to the Institute will be able to see for themselves the ingredients of the pigments used in Yamaji.

Recording of Hanago by the Izumi school of Kyogen

Recording of Mr. SATO Tomohiko

 There are two main schools of Kyogen, the Izumi and the Okura. Kyogen performances and scripts of the two schools differ. In fact, traditions can differ even within the same school. There are three traditions within the Izumi school: Kyogen Kyodosha (Nagoya), the NOMURA Matasaburo Family (now residing in Nagoya), and the NOMURA Manzo and NOMURA Mansaku families (originally from Kanazawa). The Department of Intangible Cultural Heritage has studied Kyogen performances. As part of that research, SATO Tomohiko of Kyogen Kyodosha was recorded performing Hanago. Hanago is a piece primarily in the form of a ballad. Hanago is a naraimono, or a piece requiring special skills that one is not authorized to perform until reaching a certain age.

The 2012 General Assembly of the Japan Consortium for International Cooperation in Cultural Heritage convened and the 12th seminar on “International Trends in Safeguarding Cultural Heritage Protection” was held

Keynote lecture

 The 2012 General Assembly of the Japan Consortium for International Cooperation in Cultural Heritage was convened on March 15th. The Secretariat General reported on Consortium projects in 2012 and projects planned for the coming year. This was followed by the 12th Seminar, which started with a keynote lecture by Jean Wee, Director, Preservation of Monuments Board, Ministry of Community, Culture, Youth and Sports, Singapore, entitled “International Cooperation-OMNI-Logue: Your voice is Mine.” Afterwards, four other lectures described recent trends in the safeguarding of cultural heritage with a focus on international conferences that mainly took place last year.
 FUTAGAMI Yoko, Head of the Research Information Section of the Department of Art Research, Archives, and Information Systems, National Research Institute for Cultural Properties, Tokyo, described deliberations concerning inscription of sites in accordance with the World Heritage Convention. Ms. FUTAGAMI also described inscription of a Palestinian site on the World Heritage List. NISHIBAYASHI Masuo, Ambassador in charge of Cultural Exchange and Ambassador in charge of Arctic Affairs, reported on the Closing event of the World Heritage Convention 40th Anniversary celebrations, held in Kyoto last year, and one of its outcomes, named Kyoto Vision. Mr. NISHI Kazuhiko, Associate Specialist for Cultural Properties of the Agency for Cultural Affairs, provided an overview of events in Toyama and Himeji held in conjunction with the celebrations’ Closing event. Mr. NISHI also described the Toyama Proposal on Heritage and Sustainable Development and the Himeji Recommendations. MIYATA Shigeyuki, Director of the Department of Intangible Cultural Heritage of the National Research Institute for Cultural Properties, Tokyo, reported on deliberations concerning inscription of files on the Representative List of the Intangible Cultural Heritage of Humanity. Mr. Miyata also mentioned recent remediation of the regional gap in inscriptions and conduct of the 7th Session of the Intergovernmental Committee for the Safeguarding of Intangible Cultural Heritage.
 The topic of international trends in protecting cultural heritage is usually brought up at seminars annually and attendees always number more than 50 people. Information on recent trends is greatly needed. The Japan Consortium for International Cooperation in Cultural Heritage will continue its efforts to share information through seminars .

Work to move the bronzed black kite of the Shochuhi Russo-Japanese war memorial in Sendai

Movement of the bronzed black kite of the Shochuhi memorial (Feb. 7, 2013)

 Erected on the ruins of the keep of Sendai Castle (or Aoba Castle), the Shochuhi memorial was erected in 1902 to commemorate the fallen from the Imperial Army’s 2nd Division, which was located in Sendai. The Shochuhi memorial is currently under the care of Gokoku Shrine, Miyagi Prefecture. As was previously reported (Jan. and June, 2012), the black kite in bronze that sat atop the memorial’s stone pedestal fell as a result of the Great East Japan Earthquake. With its Secretariat in the National Research Institute for Cultural Properties, Tokyo, the Committee to Rescue Cultural Properties Damaged by the Tohoku Earthquake and Tsunami worked to rescue the memorial as a cultural property. Bronze fragments that were scattered around and atop the pedestal were previously collected. The bronzed black kite had been left as it was for a prolonged period, but it was finally moved this February.
 Work started on February 4 and was supervised by Bronze Studios and Sekiho, which have previously worked to restore outdoor sculptures. A 4.5×4 m bed of steel plates was placed on the ground in front of the east side of the Shochuhi memorial. On February 7, a 25-t all-terrain crane lifted the bronzed black kite and placed it atop the bed of steel plates. A covering was then fashioned from corrugated plastic panels, and all work was completed on February 9. Snow occasionally fell during the work but was cleared. Luckily, lifting of the bronzed black kite was marked by good weather on the 7th; lifting proceeded as relevant personnel and members of the local media looked on. Movement will allow inspection inside the broken neck of the black kite statue. The head of the statue was found to be joined to the body by a mortise-and-tenon joint and an inscription was found to read “Head joined October 4, 1902/At the Tokyo Fine Art School/ In Commemoration of this Date.” Such discoveries are important to the study of the Shochuhi memorial. Like previous work to rescue the Shochuhi memorial, movement of the bronzed black kite was carried out thanks to donations to the Institute from Kaikai Kiki Co., Ltd. (President: MURAKAMI Takashi) to help with the Cultural Property Rescue Program.
 Movement of the bronzed black kite under cover will prevent damage to broken areas by rain for the time being. Nevertheless, the bronzed black kite was damaged extensively by the fall, e.g. its left wing broke off, so it is far from its majestic visage prior to the disaster. Other threats have yet to be dealt with, such as bronze adornments atop the pedestal falling off and complete collapse of the pedestal due to penetration by rainwater. Future steps must be taken to conserve this rare memorial from the Meiji Era.

Presentation of results of an optical study of AI-MITSU’s Landscape with an Eye

Presentation of results of an optical study of AI-MITSU’s Landscape with an Eye

 On February 26, OTANI Shogo (Senior researcher, National Museum of Modern Art, Tokyo) delivered a presentation entitled “AI-MITSU’s Landscape with an Eye” at a seminar of the Department of Art Research, Archives, and Information Systems. The work’s creator, AI-MITSU (born: ISHIMURA Nichiro, 1907–46), left behind a body of work through his unique sense of shapes and steadfast use of oil paints. As a painter, AI-MITSU is an essential part of Japan’s history of Western-style painting from the 1930s to 40s. Among his numerous works, Landscape with an Eye is not merely a result of surrealism in modern Japanese art; rather, the piece is renowned for its unique depiction of the fantastic amidst darkening times.
 The Department of Art Research, Archives, and Information Systems previously conducted optical studies with the National Museum of Modern Art, Tokyo through a research project on Research on the Use of High-Resolution Digital Images and Comprehensive Research on Modern and Contemporary Art in January and April 2010. Full-scale color images and near-infrared reflectance images from those studies will be exhibited on the second floor of the Institute.
 A participant in the optical study of AI-MITSU’s Landscape with an Eye, OTANI presented the results of his research, which builds on study and discussion of the images obtained. OTANI’s presentation brought up several issues. Although AI-MITSU’s work is generally considered to be typical of surrealist painting in Japan, numerous questions remain, e.g. what specific impact did the work have and what was AI-MITSU trying to depict? Near-infrared reflectance imaging and near-infrared transmittance imaging were done, allowing a glimpse into the process AI-MITSU used to produce the work. The comprehensive presentation discussed a single work from multiple perspectives. It reviewed the work in terms of the motivation behind its creation and its motifs and depictions in light of the imaging information and it confirmed the work’s place in art history via remarks on and assessments of the work thus far.

Conference on “Reducing Energy Use in Museums Considering Environments for Conservation of Cultural Properties” – LED lighting and reduced energy use

During the Conference (speech by FUJIWARA Takumi)

 Over the past few years, white LED technology has progressed dramatically. Improved color rendering and increased variation in color temperatures have reached the level where installing white LEDs as lighting for exhibitions can be considered. Such lighting requires color reproduction and creation of various lighting effects. That said, many museum staffs have expressed concerns about the effects of such lighting on materials, differences between objects viewed under that lighting and under conventional lighting, and whether power consumption can be reduced commensurate with the costs of installation. Given the need to share information on the development of white LEDs and the current state of exhibit lighting, a conference on reducing energy use in museums was held on Feb. 18, 2013.
 The Conference featured respective talks by two experts on development of LED technologies and two curators from art museums that installed white LEDs as exhibit lighting. One expert on the development of LED technologies, FUJIWARA Takumi, President of Light Meister Co., Ltd., discussed the basic principles of white LEDs and the latest technological trends. The other expert, MIYASHITA Takeshi of CCS Inc., talked about the development of new type of white LEDs, stimulated by violet LED, which emit light that is closer to natural light than that emitted by conventional white LEDs. MIYASHITA also talked about the installation of those LEDs in museums. The Yamaguchi Prefectural Art Museum installed white LEDs as exhibit lighting a while back. KAWANO Michitaka of the Art Museum described exhibits and staging that fully capitalized on the features of LED light sources, such as control of color temperatures. TAKANASHI Mitsumasa of the National Museum of Western Art described reduced energy use based on measurements. In addition, TAKANASHI described the characteristics of white LEDs from the perspective of someone who is constantly in contact with artworks, i.e. differences between oil paintings viewed under that lighting and under conventional lighting.
 Over the past few years, production of energy-inefficient incandescent bulbs has gradually diminished and halted as a step to combat global warming. In addition, the Minamata Convention on Mercury, which is expected to be adopted globally this October, is expected to dictate reduced production of products containing mercury after 2020. Continuing to use fluorescent lighting may no longer be limited. Installation of alternative lighting is inevitable for facilities handling cultural properties. Reflecting this fact, the Conference was attended by 130 individuals from around the country. The question-and-answer portion covered a range of topics, from issues concerning materials conservation such as elimination of ultraviolet radiation and temperature changes to issues concerning color temperatures and staging. In order to deal with issues raised during the Conference and to meet the needs of relevant personnel, we will continue to gather the latest information on organic electro-luminescence, the next generation of lighting to follow white LEDs, and we will continue to study and assess that lighting from the perspective of conservation. We will also convey the needs of museums and art museums to lighting developers and facilitate the use of these light sources as exhibit lighting.

The Networking Core Centers for International Cooperation on Conservation of Cultural Heritage Project for the Protection of Cultural Heritage in the Kyrgyz Republic and Central Asia

A trainee cleaning a metal object

 The Japan Center for International Cooperation in Conservation has undertaken a four-year training project since 2011. As part of the project, a series of workshops will be held covering “documentation,” “excavations,” “conservation,” and “site management.”
 The fourth workshop, a “Training Workshop on Conservation of Archaeological Objects and Documentation of Excavated Objects,” was held jointly with the Institute of History and Cultural Heritage, the National Academy of Sciences, Kyrgyz Republic from February 8 to 14, 2013. A total of eight young Kyrgyz trainees participated in the workshop.
 During the workshop, trainees received practical training in “pottery reconstruction,” “metal conservation,” and “pottery drawing” using archaeological objects that were excavated during the 3rd workshop in the summer of 2012.
 The Japan Center for International Cooperation in Conservation plans to conduct various workshops to protect cultural heritage in Central Asia next year as well.

Survey of the Philippines as a Partnering Country by the Japan Consortium for International Cooperation in Cultural Heritage

Interview with members of the National Commission of Culture and the Arts
Interior of San Agustin Church, a World Heritage Site
Callao Cave on the northern part of the island of Luzon

 The Japan Consortium for International Cooperation in Cultural Heritage surveyed the cultural heritage of Myanmar from February 14th to the 25th. The main goal of the survey was to explore current and future developments in international cooperation to preserve cultural heritage in the Philippines by visiting sites firsthand and determining the Philippines’ specific requirements for cooperative efforts. Sites such as churches and houses from the Spanish colonial period as well as prehistoric shell mounds and rock art were visited along with museums and libraries. Survey members gathered information and interviewed relevant personnel.
 Results of the survey indicated that the public needs to be increasingly aware of the need to protect many historic buildings and archaeological sites as cultural heritage. That said, educational institutions involved in protecting cultural heritage are lagging, so personnel need to be promptly trained. Cooperation with local authorities is a key aspect of protecting cultural heritage, and provision of that protection depends on local politics.
 Interviews indicated that the Philippines wishes Japan to help foster academic cooperation between the countries and train Filipino personnel with an eye toward increased public awareness of cultural heritage and cooperation in Asia. Japan needs to capitalize on its previous cooperative efforts in Asia and provide support with an eye toward cooperation with other Asian countries. Such steps are essential to determining ways to protect the cultural heritage of the Philippines.
 The year 2013 is the 40th Year of ASEAN-Japan Friendship and Cooperation, and Japan is expected to cooperate more with the region. In order to explore the nature of cooperation Japan can provide with regard to preserving cultural heritage, plans are to determine what support Japan can provide while continuing to gather information and coordinate with relevant institutions.

Optical study of the Nissokan doors at the Phoenix Hall of Byodoin Temple

The optical study of the Nissokan doors (two panels)

 The Phoenix Hall of Byodoin Temple, where the temple’s principal image is enshrined, has two doors at its entrance the rear corridor, featuring Nissokan illustrations intended to evoke Paradise. The door on the right-hand side depicts mountains with buildings in their midst, including a Buddhist temple, while the images on the left door include the expansive sea and the setting sun above the horizon. While naturally the passing years have caused many parts of the paintings to peel off and a number of repairs were made by later generations, in light of the tough environment in which they were placed the original pictures can be said to have survived the years well. These are very important paintings in that they are rare examples of full-fledged paintings remaining from the mid-Heian Period. In September 2012, as requested by Byodoin Temple the National Research Institute for Cultural Properties, Tokyo conducted an optical study focusing chiefly on the paint remaining under the sliding locks that had been installed atop the pictures in later years, since those locks had just been removed.
 This more recent study focused chiefly on the outer frame of the doors, a part of the Nissokan doors not previously subjected to full-fledged optical study. Parts of the frames are decorated with patterns that from their materials are thought to be original. From January 8 through January 10, 2013, Seiji SHIRONO and Tatsuro KOBAYASHI of the Planning and Information Department took high-resolution color images, fluorescence images, and infrared images of the Nissokan images themselves along with other subjects including fragments of the Jobonjoshozu doors of the Phoenix Hall, preserved in the Hoshokan, and parts of the ceiling panels. Yasuhiro HAYAKAWA of the Center for Conservation Science and Restoration Techniques used fluorescence X-ray analysis to study the materials used in the frame patterns. After study of the data obtained, plans call for reporting the data to the Byodoin and then announcing it publicly in the future.
 Prior to this study, the Nissokan doors were moved to the Hoshokan, a museum facility equipped with an environment resembling that of the interior of the Byodoin, and they will be preserved and made available for public viewing in this facility. Plans call for installation of new doors with reproductions of the Nissokan paintings inside the Phoenix Hall, and this optical study, like its predecessor, is likely to contribute greatly to the process of preparing these reproductions.

Study of the Koshikijima no Toshidon visiting-deity event in Kagoshima Prefecture

A presentation during the study meeting
A Toshidon revealing its face

 I conducted a study of the Toshidon event held on New Year’s Eve on Shimo-Koshikijima Island in the city of Satsumasendai, Kagoshima Prefecture, in which deities are said to visit bringing good luck. Koshikijima no Toshidon was named an Important Intangible Folk Cultural Property of Japan in 1977, and in 2009 it was added to the Representative List of the Intangible Cultural Heritage of Humanity by UNESCO.
 The Toshidon deities are said to visit on the evening of December 31, riding headless horses. Children of ages three through eight come out to meet them in the living rooms of their homes. The deities emerge from the darkness accompanied by low, groaning voices saying “Oruka, oruka” (“Is anybody there? Is anybody there?”) and the sound of a hand bell, appearing in the corners of the living room and questioning the children. They both scold and threaten the children for the bad things they have done over the year and praise them for the good things they have done, along with having children show off their own talents such as singing, dancing, or multiplication tables and praise them for how they do. Lastly, they admonish the children to be good and give them large rice cakes called toshimochi, before disappearing.
 This is a deeply frightening experience for small children, and some run away in tears, but after successfully completing the questions and answers they seem relieved, feeling as if they have accomplished something. I also was impressed by the way other family members too are moved to tears, perhaps as a result of thinking about the children’s growth. People in the local community consider the Toshidon an educational event for children, and it probably could be said that in one aspect this event has continued to the present day thanks to the way this meaning of the event, easy to understand in contemporary society, has been discussed and shared in the community.
 However, it is a fact that there are many issues regarding the continuation of this tradition. The biggest problem is the low birth rate, as only four of the six designated Toshidon conservation associations conducted the event this year. Even in the Teuchi Motomachi conservation association, which I accompanied on its rounds, only five homes were visited this year compared to a number of 10 homes up until a few years ago, and two of these five were grandparents’ homes where grandchildren were visiting for the holiday.
 Another major issue is how to balance the tradition with tourism. Since the Toshidon being named an Intangible Cultural Heritage of Humanity in 2009, the Motomachi conservation association has actively accepted researchers and other visitors coming to view the event. This year, the group was accompanied by about 15 onlookers, including myself. As the Toshidon becomes well-known in Japan and around the world and attracts the interest of many people, this provides significant motivation to the local community to continue the tradition and also serves as a tourism resource. However, at the same time I sensed that an important issue in the future would be that of how to preserve and balance its significance and atmosphere as a religious observance and ritual.

Sixth study meeting held on traditional restoration materials and synthetic resins

A presentation during the study meeting
A general discussion during the study meeting

 On Thursday, January 24, the Center for Conservation Science and Restoration Techniques held a study meeting in a seminar room at the Research Institute on the theme of deterioration and repair of paint and other coloring materials in architectural cultural properties, one subject involved in traditional restoration materials. The content of this study meeting could be described as a continuation of the third study meeting held in FY2009, on current conditions and issues in study and repair of lacquers in architectural cultural properties, and the fifth in FY2011, on study and repair of traditional paints in architectural cultural properties. Historically, paint and other coloring materials such as those on the exteriors of architectural cultural properties have been subjected to repeated repair because they are liable to material degradation and bio-degradation in Japan’s climate.
 This study meeting provided the latest information on various issues related to these matters, from the individual perspectives of conservation and restoration science (paint and coloring materials and biology), structural repair sites, and administrative guidance. First, KITANO Nobuhiko of the Technical Standard Section discussed deterioration of paint and coloring materials, and then KIGAWA Rika, head of the Biological Science Section, identified topics related mainly to insect damage at the Shrines and Temples of Nikko World Heritage Site and mold damage at Kirishima-Jingu shrine, as examples of biodegradation of materials including paints and coloring, as well as examples of responses to such damage. Next, SHIMADA Yutaka of the Cultural Properties Division in the Department of Guidance of the Kyoto Prefecture Board of Education reported on examples of repairs to the paint and coloring of Iwashimizu Hachimangu Shrine and to the paint of the Phoenix Hall of Byodoin Temple, and HARASHIMA Makoto of the technical office of Itsukushima Shrine reported on an example of repairs to the paint of the main building of Itsukushima Shrine. Lastly, TOYOKI Hiroyuki, Architecture and Other Structures Division, Agency for Cultural Affairs, described an overview of the fundamental concepts behind repairs to paint and coloring materials currently conducted by the Agency. The meeting was well received by participants, who showed high levels of interest in the content of its themes because they were directly related to repair of paint and coloring materials.
