A slide from the lecture ‘The Work of an Art Librarian’
On December 6, 2024, KIKKAWA Hideki, Head of the Modern / Contemporary Art Section at the Department of Art Research, Archives and Information Systems, was invited to give a lecture titled “The Work of an Art Librarian at the ART with” series held at Sen-oku Hakukokan Museum Tokyo. The ART with series features experts from various fields related to art, offering insights into their professions for a broad audience of art enthusiasts.
In this lecture, Mr. KIKKAWA presented a wide range of specialized librarian skills based on his career not only at the Tokyo National Research Institute for Cultural Properties (TOBUNKEN) Library, but also at the Art Library of the Museum of Contemporary Art Tokyo and the Art Library of the National Art Center, Tokyo. In particular, he discussed the enjoyment of supporting researchers and curators in their studies and creating frameworks that enhance the value of library collections through cataloging and compiling bibliographies on artists.
TOBUNKEN engages in collaborative efforts among experts from various fields to preserve cultural properties for future generations. Librarians well versed in art materials also play a crucial role in supporting these efforts, considering the future of cultural properties and continuing to safeguard them. This lecture provided an opportunity not only to introduce their work, but also for Mr. KIKKAWA to reflect once again on its significance. He has expressed that nothing would be more gratifying to him than for art enthusiasts, professionals from other fields, or students who attended the lecture to have found the role of an art librarian appealing and had deepened their interest in the preservation of cultural properties.
On December 15, 2024, a group of researchers from Korea, France, and the U.S. visited the library of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN). The group had come to Japan for a research presentation at the Korean history Forum, held at Dokkyo University from December 13 to 14, and TOBUNKEN was selected as a destination to visit during their stay in Japan. Guided by Mr. TASHIRO Yūichirō, the group took a tour of the Institute’s collection of books and rubbings, which have been collected since 1930.
Among the missions of the Archives Section of the TOBUNKEN Library* are to provide information on cultural properties to experts and students and to create an environment for the effective use of such materials. We hope that the materials of our institute, which are of high value by international standards, will be widely utilized not only in art history research, but also in Asian history research and historical research in general, and will contribute to the development of research on cultural properties that are the common heritage of all humankind.

The seminar
At the 8th Seminar of the Department of Art Research, Archives and Information Systems held on 18 December 2024, Ms. TSUKIMURA Kino, Researcher of the Department of Art Research, Archives and Information Systems, gave a presentation entitled “Basic Research on the Nagao Museum – Towards a Clarification of its Relationship with the Art Research Institute.”
The Nagao Museum was established by NAGAO Kin’ya (1892-1980) and his wife Yone (1889-1967), the founders of Wakamoto Pharmaceutical Co. Ltd., at their villa ‘Senko Sansō’ (Kamakura, Kanagawa Prefecture) in 1946. The museum had many masterpieces in its collection, such as Tea-Leaf Jar with a design of wisteria by NONOMURA Ninsei (now in the MOA Museum of Art, in Shizuoka prefecture), Tachi Signed Chikushūjū Sa (Named “Kōsetsu Samonji”) (now in the Fukuyama Museum of Art), and Shrike in barren tree by MIYAMOTO Musashi (now in the Kuboso Memorial Museum of Arts, Izumi). Over time, however, NAGAO Kin’ya and Yone gradually gave up these works and the museum was dissolved around 1967. More than half a century has passed since the de facto closure of the museum, and the actual operation of the museum and the status of entire collection are still unclear.
However, when purchasing and exhibiting works, Kin’ya and Yone were closely involved with staff members of the Art Research Institute (Bijutsu Kenkyūjo), the predecessor of the Tokyo National Research Institute for Cultural Properties (TOBUNKEN). It is noteworthy that Kin’ya participated as a board member in the activities of the Bijutsu Konwa-kai and the Society of Friends of Eastern Art (Tōyō Bijutsu Kokusai Kenkyūkai), which were based at TOBUNKEN, and had the opportunity to introduce the collection to researchers.
The lecture raised the possibility that the interaction between the NAGAO couple and art historians was related to the evaluation of the Nagao Museum collection, as a result of an examination of relevant documents remaining at TOBUNKEN.
The presentation was followed by a lively exchange of views, including valuable testimony from researchers with knowledge of the situation at the time of the museum’s dissolution. The Nagao Museum is important for the history of the transmission and evaluation of works, and future research will be conducted to gain a fuller understanding of the museum.

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.

Public lecture
On Friday, December 6, 2024, the 18th Public Lecture was held at the Tokyo National Research Institute for Cultural Properties (TOBUNKEN), in the basement seminar room and lobby. From 2015 to 2018, TOBUNKEN had conducted surveys on silk manufacturing techniques of Mr. SHIMURA Akira (certified individual practitioner of “conventional silk manufacturing” a selected conservation technique) and Ms. AKIMOTO Shigeko of the Silk Textile Manufacturing Research Institute of Katsuyama Co. Ltd (hereafter, Silk Textile Manufacturing Research Institute) located in Iijima Town, Nagano Prefecture. These techniques are used for the production of textile restoration materials. Based on the surveys, we published a research report, “Manufacturing Techniques of Silk Textile Research Report on Transmission of Intangible Cultural Heritage (Traditional Craftsmanship)” and an associated DVD (TOBUNKEN Publication Repository) (hereafter “Manufacturing Techniques of Silk Textile Research Report”) in 2021. This public lecture featured those techniques and served to introduce the surveys and documentation project conducted by TOBUNKEN and to share the situation of the textile restoration techniques and restoration material manufacturing techniques with a wider audience.
At the public lecture, Ms. KIKUCHI Riyo, Senior Researcher of the Department of Intangible Cultural Heritage, explained the purpose of this lecture event, Ms. TAHIRA Namiko, Senior Specialist of the Agency for Cultural Affairs, and Dr. BANNO Yutaka, Director of the Komagatake Silk Museum and Professor Emeritus of Kyushu University, delivered lectures respectively titled “Conservation Techniques for Cultural Properties: Conventional Silk Manufacturing” and “Conservation of Silkworm Eggs in Japan.” After the lectures, time was allocated for the audience to view a lobby exhibition, which displayed cocoons of various types of silkworms borrowed from Dr. Banno, five kimono costumes made of silk textiles manufactured at the Silk Textile Manufacturing Research Institute using different reeling techniques and woven patterns, and drawstring pouches made from the same textiles as the exhibited Kimono costumes.
After a break, a video titled “Widespread Adoption Phase Manufacturing Techniques of Silk Textile Research Report” was screened, Ms. AKIMOTO reported on “the Current Situation and Inheritance of Silk Textile Manufacturing Techniques,” and Ms. YODA Naomi from Shokakudo Co., Ltd. and Ms. AKIMOTO joined in a discussion titled “Textile Restoration and Requests for Restoration Materials through the Actual Cases.”
This public lecture gave us a good opportunity to think about the importance of inheriting the current techniques by featuring intangible techniques associated with tangible cultural properties. Our department will continue to publish the research results on intangible techniques and hold opportunities to discuss the challenge.
The terraces in front of the Central Complex (Cruciform Terrace is highlighted in red)
Excavation at the Cruciform Terrace
Conservation of the Central Tower's original stone members
Ta Nei Temple is a Bundist temple estimated to have been built during the period from the end of the 12th to early 13th century. A large rectangular terrace and a Cruciform Terrace are aligned at the eastern side of the Central Complex, which is the front side of the Temple. While a large terrace is often set in front of the building complex in the other temples of the same period, the style connecting a cruciform terrace in front of a rectangular terrace is unique. Therefore, these are considered important remains, when we think about the characteristics of Ta Nei Temple. However, as tree roots had grown on the terraces and the soil infill layer inside the terraces had unevenly subsided, the terraces had largely collapsed, especially the Cruciform Terrace.
Therefore, the Japan Center for International Cooperation in Conservation dispatched four staff members from the end of November to late December 2024 and started an excavation of the Cruciform Terrace as a preliminary investigation for future discussion on the conservation and restoration methods, working with the archeological staff of the Authority for the Protection and Management of Angkor and the Region of Siem Reap (APSARA) of the Cambodian government. At the same time, surveys on internal structures, damage, and remaining status of fallen stone materials were conducted and fundamental discussions related to the direction of future restoration were held.
As a result of the excavation, many scattered stone materials that could be considered to have formed the Cruciform Terrace were detected under the accumulated soil around the Terrace. Furthermore, some parts of the foundation work layer and the internal structure of the Terrace were revealed. When we investigated the current level of the Terrace foundation, some subsidence was observed toward the ends of southern and northern wings, but the foundation itself remained in relatively good condition. On the contrary, it was confirmed that the side walls and floor materials were lost in many areas and that, as a result, an inner infill mainly consisting of sand had flowed out at the southern and northern sides of the eastern wing and around the southern wing of the Terrace. Almost no materials that can be estimated to have been used for the middle layer of the side walls of the Terrace were found, which could suggest that these stone materials were taken away intentionally during some past era(s). Based on these observations, we discussed the restoration methods of the Cruciform Terrace with APSARA staffs and mostly agreed on a basic direction and future plan for the restoration.
Simultaneously, we conducted some additional conservation work of stone materials at the eastern and western entrances of the Central Tower. Partial restoration of these areas had been ongoing until August 2024 (Field Activities Parts XVI to XVII). In addition, during the mission, meetings of the International Coordinating Committee (ICC-Angkor/Sambor Prei Kuk) were held in Siem Reap City from December 11 to 13. We reported on the completion of restoration of the entranceway of the Central Tower and the investigation on the Cruciform Terrace in front of the Central Complex.
Landscape of the Al-Khokha area
The treatment of mural painting fragments
The Japan Center for International Cooperation in Cultural Heritage is conducting a joint research project on the conservation and restoration of mural paintings in a rock-cut tomb located in the Al-Khokha area on the west bank of Luxor. This project is being carried out in cooperation with the Waseda University Institute of Egyptology and the Egyptian Ministry of Antiquities. The wall paintings under study were discovered in 2013 by Professor Emeritus Jiro Kondo in the tomb of Khonsuemheb and are estimated to date back to around 1200 BCE, during the New Kingdom period.
This mural painting is painted on a wall made of mud plaster applied to the surface of limestone. Previous research had focused on developing methods for cleaning surface dirt and identifying suitable restoration materials and techniques for areas where the plaster has detached or fallen off. In our field research conducted from November 20 to December 5, 2024, we examined methods for reattaching wall painting fragments discovered during excavation to their original positions. As a result, we achieved positive outcomes regarding the reinforcement of the wall substrate and protection of the painting’s surface. Furthermore, we were able to confirm certain successes in the reinstallation process, using materials similar to the original ones, such as mud and clay, to return the fragments to their original locations. Moving forward, we will continue to monitor the effectiveness and stability of the treatments applied and observe their long-term outcomes.
This research has been carefully advanced through a process that involved foundational studies, a series of experiments, and the development of treatment methods with practical considerations in mind. The results are unprecedented in Luxor and have been highly praised by the Egyptian Ministry of Antiquities and local experts. Moving forward, we will continue to promote research that contributes to the conservation and restoration of the numerous wall paintings created during the New Kingdom period, aiming for further achievements in this field.
Workshop “Conservation of Historic Settlement in Kirtipur”
Historic house in Khokana settlement totally collapsed due to damage brought by heavy rain the previous summer
Aiming for the conservation of a historic house that faces the historic square in Old Kirtipur, a joint survey between Kirtipur Municipality and Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been underway since 2023. During the dispatch of one staff member from TOBUNKEN from December 20 to 27, 2024, a workshop titled “Conservation of Historic Settlement in Kirtipur” was co-organized by the municipality and TOBUNKEN and held on December 26 to promote a common understanding for the preservation and utilization of the target house.
The workshop consisted of two sessions. In the morning session, a lecture regarding the “good practices of the preservation and utilization of a historic house in Nepal” was presented by staff from Kathmandu Valley Preservation Trust (KVPT), and the results of a survey of the target house were reported by the TOBUNKEN staff member and Nepalese experts of the research team. More than 50 participants attended the workshop, including the Kirtipur mayor, deputy mayor, ward chairperson, and the house owners and their family members. Both, local government and house owners’ sides expressed positive opinions towards the preservation and utilization of the house. In the afternoon session, 16 members from the owners’ family joined a brainstorming session to discuss various topics regarding their house, such as memories, emotions, the future surrounding the building, where they have spent long periods of their lifetimes over many generations, past and presents.
Although there is still long way to go before concluding the decisions on the actual implementation of the preservation, the workshop brought an opportunity to share the value of the historic house through dialogue, and seemed to push the related stakeholders to move one step forward to its preservation.
Additionally, a quick survey on the historic settlement of Khokana, which is on the World heritage tentative list, was also made during this mission. While most of the historic houses in the settlement were rebuilt after the Gorkha earthquake in 2015, a few historic houses remained in the central area that are said to have been built in 19th century. We had been consulted by locals regarding their preservation; however, unfortunately, one of the historic houses had collapsed during the previous September due to damage brought by heavy rain. Although it was a consolation that no-one was injured in the collapse, it is regrettable that such a valuable building, which had watched over Khokana for more than 100 years, was lost forever, and necessary support was not able to reach them when they were in need.
