Retouch work on the East Gate after restoration
Archeological investigation for digging a temporary ditch around the East Gate
Areas at risk on the East Tower Shrine of the central building complex: emergency replacement of reinforcements
The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) continues to support the conservation and sustainable development project of Ta Nei Temple by the Authority for the Protection and Management of Angkor and the Region of Siem Reap (APSARA) in Cambodia. We dispatched three expert members from June 12th to July 3rd, 2022. The mission aimed to supervise the finishing works for the restoration of the East Gate, conduct archaeological investigations for setting a new drainage ditch from around the East Gate, and survey the areas at risk of the central building complex.
For the East Gate restoration, in May, the APSARA team began retouching the parts identified at our previous dispatch in January 2022. We assessed their working status and further discussed how to deal with the broken part of stones and finish the surface with sculptures, and other aspects with APSARA. Although this resulted in additional work, we almost completed the given work by the end of June.
Furthermore, the water drainage around the East Gate had been an outstanding issue. In discussions with APSARA, it was decided to cut a temporary drainage ditch from the west side of the East Gate to the North Moat. We tasked Mr. KAHSHA Hiroo, a visiting researcher, with conducting archeological investigations related to a new drainage ditch set-up. We dug up a ditch carefully, to avoid damaging the original land surface at the time of constructing the East Gate and the Cruciform Terrace, and completed an approximately 30-meter-long temporary drainage ditch. We plan to carefully monitor its effect during the rainy season until October, in cooperation with on-site staff.
In the central building complex, we investigated the areas at risk in detail by scaffolding around the buildings of the Central Tower and the East Tower Shrines, which were identified as the highest priority for safety measures based on the discussions with the APSARA risk map team. Because the old wooden reinforcements in the areas at risk were severely deteriorated by pest damage and other factors, replacements using durable materials had been requested for some time. Following APSARA’s request, it was decided to tentatively replace the wooden reinforcements with scaffolding tubes and couplers. We renewed the reinforcements in a part of the Central Tower Shrine and three parts of the East Tower Shrine. We, in discussions with APSARA staff, tried to pursue minimum intervention while carefully examining lacking areas or cracks in the stone materials caused by imbalanced load transfers. Furthermore, safety measures were implemented by setting temporary fences along visitor routes to prevent tourists from entering the areas at risk.
We also held a working session with the Department of Tourism Development and Culture of APSARA as they planned biking tours around the area, including Ta Nei Temple. We exchanged ideas about the development of tourist facilities and discussed measures to protect the ruins, secure the visitors’ safety, and enhance visitors’ understanding of the ruins. We aim to further discuss effective ways to achieve balance between the appropriate protection and tourism for this site.
The 30th seminar
Online discussion
The 30th Seminar titled Cultural Heritage x Citizen Engagement = Potential for Multi-Actors’ International Cooperation was held by the Japan Consortium for International Cooperation in Cultural Heritage (JCIC-Heritage) in webinar format on February 11th, 2022. The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) was commissioned JCIC-Heritage secretariat by the Agency for Cultural Affairs.
This seminar hosted discussions about new possibilities of international cooperation for cultural heritage, expected to be realized through the participation of multiple actors. The discussion was based on cases utilizing the knowledge of domestic community design involving citizens and co-work by public and private sectors, as well as cases related to multiple developments of international exchange hosted by the private sector.
Ms. MURAKAMI Kayo (Senior Cultural Properties Specialist of the Agency for Cultural Affairs) introduced her own activities as a technical cooperation project specialist during her participation in the Japan Overseas Cooperation Volunteers titled Tourism Development in Ecomuseum Concept through International Cooperation – The Case of Al-Salt City of Jordan. Ms. CHIU, Ru Hwa (Secretary General of the Institute for Historical Resources Management) introduced the various activities she has accumulated over multiple decades in the private sector titled Collaboration in Heritage Conservation – Co-learning Journey.
Prof. NISHIMURA Yukio (professor of Kokugakuin University) and Mr. SATO Hiroshi (Chief Senior Researcher of Research Operations Department, the Institute of Developing Economies, Japan External Trade Organization (JETRO)) joined the panel discussion with the abovementioned speakers during the latter half of the seminar. The seminar prompted active discussions. The participants discussed the importance of consensus building, carefully considering the concerned parties’ interests, and the necessity of efforts to share the value of cultural heritage by various actors.
Nearly 120 people participated in this seminar both from Japan and abroad. JCICC plans to pursue the possibilities of Cultural Heritage Cooperation by multiple actors. Please visit our website for the seminar details https://www.jcic-heritage.jp/20220221/(Japanese Only).

The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) provides technical support and training for human resource development to the Department of Culture (DoC), Ministry of Home and Cultural Affairs of Bhutan, to conserve vernacular houses. Since F.Y.2019, we have been entrusted with the Network Core Center Project for International Cooperation in Cultural Heritage by the Agency for Cultural Affairs (ACA), which conducts joint architectural surveys with the Division for Conservation of Heritage Sites (DCHS) of the DoC and practical training for local stakeholders to ensure heritage conservation. However, in response to the COVID-19 pandemic, we had to pursue our mission remotely, by preparing reference books for governmental sectors and educational materials for schools. In F.Y.2021, although we were prepared to conduct a joint survey anticipating the end of the COVID-19 pandemic, this did not materialize. As an alternative, we held an online joint study session with the DoC on March 7th, 2022.
Twenty-two people, including TOBUNKEN and DoC staff members, as well as external cooperative experts, attended the session. The Bhutanese side provided the latest information about the preliminary stage of the joint survey. Mr. Pema, a senior engineer of the DCHS, described the cultural and regional characteristics of Bhutan’s central and eastern regions, focusing on settlement patterns. Mr. Pema Wangchuk, an architect of the DCHS reported on the current situation of preparations for conducting fieldwork in the region. From the Japanese side, Professor AOKI Takayoshi of Nagoya City University, who has been conducting empirical research on earthquake resistance measures for historical buildings in Bhutan, gave a presentation on the structural characteristics of masonry buildings that are common in the region, highlighting the issues they face and methods for their conservation. We exchanged relevant know-how as joint survey team members through active discussions during each presentation. In addition, Mr. KUBOTA Hiromichi, head of the Intangible Folk Cultural Properties Section, and his collaborator, Mr. Phub Tshering from Mera, Tashigang, Eastern Bhutan, held a roundtable session on local daily life and folklore, which helped the Japanese attendees enhance their understanding of the region and customs.
Despite the ongoing COVID-19 pandemic, we need to finish the ACA project by completing bookmaking, but we hope to launch a joint survey with DCHS as soon as the international travel bans are lifted.
Front cover of the List of the ITO Nobuo Library
The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has proceeded with the classification of documents related to the protection of cultural properties and items donated by the family of the late Dr. ITO Nobuo, a former director of the Institute (please refer to the Monthly Report on September 2021: https://www.tobunken.go.jp/materials/ekatudo/919771.html). The documents can be sorted into (1) administrative work for the protection of cultural properties in Japan, (2) administrative work for the protection of cultural properties overseas, (3) research activities related to architectural history, (4) private activities related to protecting cultural properties, and (5) written manuscripts. We added two more elements: (6) books and (7) photographs before publishing the List of the ITO Nobuo Library. The list consists of 2,185 items, some of whose details are still not clear at this stage. However, after organizing the material into seven groups, we decided to make the list accessible to researchers/experts who need them as soon as possible. The List of the ITO Nobuo Library will also be available on our website (https://tobunken.repo.nii.ac.jp/?lang=english). We hope that it will encourage heritage conservation studies and will contribute to their development in the future.
Program of the seminar “Archeology and International Contribution – Archaeology and Cultural Heritage in Israel”
An online seminar was held on February 20th, 2022, centering around the conservation, restoration, maintenance, and opening of archeological sites to the public in Israel. This seminar was the first in the series of annual seminars planned for the succeeding five years. We chose Israel for the first seminar as they have a wide variety of researchers in cultural heritage, and possess well organized cultural heritage protection system.
For the seminar, we invited two researchers from Israel Nature and Parks Authority who designate and manage the historic sites; Dr. Zeev Margalit, Architect and Director of Conservation and Development, and Dr. Dror Ben-Yosef, North District Archaeologist. Dr. Margalit took a lecture on the various challenges related to archeological site management. Dr. Ben-Yosef, in his lecture, talked about their onsite projects and how to exhibit other archaeological remains on sites known in the historical documents.
Following the two speakers, KANSHA Hiroo from TOBUNKEN, Dr. OKADA Mayumi, associate professor, the Center for Advanced Tourism Studies (CATS) of Hokkaido University, and Dr. HASEGAWA Shuichi, professor, College of Arts, Rikkyo University, conducted the lectures. KANSHA presented an overview of the Japanese archeological surveys in Israel since 1960, and. Dr. OKADA presented a discussion on how cultural heritage management has been developed in Israel through the years. Dr. HASEGAWA conducted a lecture on the challenges related to the conservation and utilization of the heritage sites through the case studies of the archeological sites in Israel where he has been engaged in its excavation.
In the latter half of the seminar, a panel discussion with all lecturers was held, facilitated by Dr. HASEGAWA. We all recognized that Israel and Japan have common challenges, such as the issue of what should be kept and what not through conservation and management of archeological sites, and the dilemma that people in charge of the conservation and management face through the panel discussion.
We would like to enhance our international cooperation projects more effectively by sharing the challenges with other countries through similar seminars targeting West Asian countries.
Displaying a wall painting “Macedonian prince with a philosopher”
The Tokyo National Museum is currently holding the Special Exhibition: POMPEII from January 14th to April 3rd, 2022. The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) cooperated on the condition survey of the artifacts for the exhibition (wall paintings, mosaics and marble statues) at the display setting prior to the opening of this exhibition.
Pompeii is a city built in the Roman period, located about 23 km southeast of Naples, a city in the south of Italy. In 79 AD, a major eruption of Mount Vesuvius, located between Naples and Pompeii, buried the city with volcanic ash and pumice in a twinkle. Time has passed; the city of Pompeii was rediscovered in 1748. Full-scale excavation was started then. Many buildings, wall paintings, and artifacts of that time have been unearthed. About 150 pieces came to Japan from the National Archaeological Museum of Naples, which holds a vast collection of artifacts excavated from Pompeii. These attract many museum visitors.
We had a chance to watch the set-up process at the exhibition venues, which we rarely experience during our usual work. In usual cases, experts from the museums owning these artifacts accompany them. However, they could not come to Japan due to the COVID-19 pandemic. Thereafter, the entire exhibition set-up was left to the staff members of the Tokyo National Museum, and the experts in fine art transportation and display. The operation is far from easy, since special attention has to be paid, not to damage the pieces while simultaneously considering exhibit conditions best tailored to audiences. There is a wall painting weighing several hundreds of kilograms amongst the pieces listed for the exhibition. It was a very good opportunity for us to realize that the exhibitions we usually visit without giving them special attention can only be accomplished due to the sincere efforts of many people.
Onsite survey after the restoration of the East Gate
Survey for the risk parts of the central building complex
Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been engaged in technical cooperation for the conservation and sustainable development project of Ta Nei Temple by the Authority for the Protection and Management of Angkor and the Region of Siem Reap (APSARA) in Cambodia. While it had been difficult to visit the site due to the COVID-19 pandemic, from January 9th to 24th, 2022, TOBUNKEN dispatched three staff experts responding to the request by APSARA for the first time after almost two years. We conducted the field survey and discussion on the points necessary for immediate consideration onsite including the East Gate under restoration as well as the parts of the central complex of the temple that are considered at risk.
The APSARA team have continued the restoration project of the East Gate started in 2019 by discussing the specific restoration direction online with us after April 2020. In January 2021, the reassembly work of the superstructure was completed up to the top. We checked the details onsite including the accuracies of the construction and the finishing details, which had not been well grasped remotely, and provided advice for improvement. Some retouching and additional works are planned based on the further discussion.
The central building complex of the temple requires immediate measures to secure visitors’ safety and prevent further damage to the ruins due to multiple risk factors including the collapse of unstable stone materials, aging of temporary timber reinforcements, and impacts by growing trees. Considering the given situation, we conducted a joint survey with the APSARA risk map team and discussed the main direction for countermeasures and the priority of temporary measures. We also recorded the current status of the towers by checking the upper part using a drone and creating 3D models from the photos taken.
In addition, the analysis of soil specimens taken in the previous archaeological survey at the front causeway was made with the assistance by Korea Cultural Heritage Foundation (KCHF), which also continues the restoration support in the Angkor archaeological site. In the APSARA Laboratory developed with Korea’s support, we conducted tests including grain size analysis and color measurement, which provided data related to the soil layer comprising the foundation of the causeway. We would like to express our gratitude to the generous support provided by KCHF.
We renewed our recognition of how important the onsite cooperative activities are, including interaction with the teams from different countries onsite and at research meetings. The mission also implemented the excavation survey of the outer enclosure and the survey on the stored sculptures from Ta Nei, which are reported separately.
The East Gate in the rainy season
The foundation of the outer enclosure and the land surface at Angkor Period unearthed
As part of the project mission from January 9th to 24th, 2022, we conducted an excavation survey of the outer enclosure remains of Ta Nei temple Under restoration of the East Gate implemented in cooperation with APSARA, the reassembly work has already been finished. However, due to the lower land surface than the surrounding area, it has been problematic in that the rain water accumulates around the gate in the rainy season. We assumed that this could hardly happen with the original setting when the temple was built, in which it was believed to have been equipped with some form of water drainage system. With this assumption, we conducted an excavation survey to understand the land surface level and terrain status at that time to plan a water drainage system around the East Gate area.
We conducted an excavation survey at the three points along the base remains of the wall that used to connect to the south and north sides of the gate (no information on the time and reason for removing the wall structure): its northeast corner and two locations where laterite blocks of the wall base are exposed up to the corner. The survey revealed that the land surface at these points in the Angkor period was about 30 centimeters below the current surface. This means that it was almost flat land without particular height difference from the surface around the East Gate. We did not find any remains such as drainage channels, so we consider that the drainage at that time depended on the natural drainage system including percolation.
The area to the north of the Gate is currently elevated, which prevents water evacuation. We will therefore remove the topsoil in that area and check if the rainwater can be discharged better. We plan to reorganize the surrounding area as well as the restoration of the temple buildings.
Damaged Dvarapala statue
Onsite survey
As part of the onsite survey mission from January 9th to 24th, 2022, the survey was conducted on the current location and status of the stone statues found in Ta Nei Temple and stored in other places. The French School of the Far East (L’Ecole française d’Extrême-Orient, EFEO) compiled the records of the discovery of the artifacts from different monument sites in Angkor. However, the systematic survey for the current status of these artifacts had not been conducted.
With the cooperation of the Angkor Conservation Office (ACO) under the Ministry of Culture and Fine Arts, we conducted a verification survey of the artifacts stored at that office against the records. There are a total of 30 plus artifacts from Ta Nei Temple on the inventory list created by the EFEO, among which, 16 items were identified at the storages of ACO this time. Most of the rest whose location remains unknown are small pieces such as hands or feet of divine statues. Among the massive statues of the gate guardian Dvarapala, which are about 2 meters high, three have lost their heads that were visible in the previous photographs. In addition, one of the Lokesvara (Avalokiteshvara Bodhisattva) statues was found to be heavily damaged. These damages are considered to be made by illegal diggings or destruction during the civil war period. The information from a French researcher onsite helped us to determine that at least two statues on the inventory, apart from the 16 items identified in the ACO, are currently stored in the National Museum of Cambodia in Phnom Penh.
We also found that a group of statues collected from the monument sites by ACO around in 1993 and 1994, when illegal diggings were most frequent, includes ones moved from Ta Nei Temple. We then identified seven Seated Buddha statues, seven Naga balustrades, and two Sinha statues. We will further investigate where they were originally located in the temple and where the rest of the artifacts are stored.
On the other hand, part of the head of a Lokesvara statue found inside the East Gate of Ta Nei during its dismantling in 2019 is stored in the Preah Norodom Sihanouk-Angkor Museum. We photographed it again for 3D model creation. The accompanying body parts have unfortunately not yet been found. It could still remain undiscovered on the site avoiding people’s eyes.
We plan to take the opportunity to conduct further surveys in the other facilities.
Poster of the Symposium the Oceans and Cultural Heritage - the Oceans Have Connected People and Products
Forum the World Connected through the Oceans by Presenters
Japan Consortium for International Cooperation in Cultural Heritage (JCIC-Heritage), which the Tokyo National Research Institute for Cultural Properties (TOBUNKEN) is commissioned as its secretariat by the Agency for Cultural Affairs, held the webinar Maritime Network and Cultural Heritage -People and Objects connected by Oceans- on November 28th, 2021.
Cultural heritage related to the oceans exists in many locations worldwide. It is a witness to people’s living, society, history, and culture at that time. Although in the past, there were scarce ways of knowing where the products transported by oceans had come from, latest technologies and analysis methods have made it possible to locate the original source of these products. This symposium aimed to introduce the international trends and case studies on the protection of cultural heritage related to the maritime network, share Japanese researchers’ contributions in this area, and consider the potential roles of Japan in facilitating international collaboration in this field.
ISHIMUMRA Tomo from TOBUNKEN briefed on the purpose of the symposium, followed by five lectures: The Appeal and Significance of Research on Sunken Ships – Time Capsules of the Sea- by Dr. SASAKI Randall from the Maritime Archaeology Lab; Opening the Sea Route, Voyages, and Shipbuilding by Dr. KIMURA Jun from Tokai University; Glass Beads Brought across the Oceans-East-West Trade and the Road of Glass by Dr. TAMURA Tomomi from the Nara National Research Institute for Cultural Properties; People Crossing the Maritime World – Islamic merchants, including the merchants of Hormuz by Dr. YOKKAICHI Yasuhiro from Rikkyo University; and Places where the Sea and Land Meet- Port Cities of Asian Waters: Shophouse & Courtyard House by Dr. FUNO Shuji from Nihon University.
Following these lectures, the forum entitled the World Connected through the Oceans was conducted with two more commentators: Dr. SUTO Yoshiyuki and Dr. ITO Nobuyuki from Nagoya University. The forum consisted of four sessions with the following perspectives: Exchange between the West and the East via the Oceans and the Lands; Ships, and their Technologies; Ocean Network in the Mediterranean World and the New Continental World; and Japan’s International Cooperation related to the Maritime Network and Cultural Heritage.
At the end of the symposium, Prof. YAMAUCHI Kazuya from Teikyo University made a closing remark. He emphasized the importance to protect and conserve cultural heritage related to the maritime network, which are witness to the fact that human beings have connected the world via their ocean explorations.
Although it was JCIC-Heritage’s first attempt to conduct an online symposium, it was successful with about 200 participants from 11 countries. The JCIC-Heritage will continue to collect and disseminate the relevant information.

The South East corner of the Shiva Temple podium before the investigation
Assuming original structure of internal podium exposed by the dismantling investigation
An earthquake of magnitude 7.8 struck Nepal on April 25th, 2015. Subsequently, several regions, including the capital city of Kathmandu, were stricken, and many cultural properties, including the World Cultural Heritage, were damaged. Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been continuing the investigation and support for the preservation of damaged cultural heritage since November 2015 through projects such as the one commissioned by the Agency for Cultural Affairs. Recently, I was asked to travel there by Japan International Corporation Agency (JICA). The investigation required partially dismantling the podium of the Shiva Temple in the Hanumandhoka Palace in Kathmandu and was conducted from December 5th–17th, 2021.
Shiva Temple, which is a 5m by 5m-multi-storied building, is considered to have been constructed in the 17th century. Its super structure had completely collapsed due to the above mentioned earthquake. TOBUNKEN conducted excavations to examine the composition of its foundation in June, 2017. To this end, we investigated the internal composition and condition of the remaining podium that was made of bricks to obtain the basic data and materials to reinforce the structure, which was essential for its full recovery.
From this investigation, we found that the bricks outside and at the upper parts of the podium were varied and uneven in composition and placement, being irregularly piled on top of each other. This suggests that such parts were restored sometime later than the original construction. On the contrary, the bricks inside and at the lower parts were standardized, and regularly and precisely piled, implying that these parts made up the original structure before restoration. These parts maintain relative stability, which supports our previous investigation outcome.
Furthermore, we plan to conduct a compositional analysis of the adhesive used to join stones at the upper structure as well as the mortar applied to bricks at the joint of the podium. We hope that the research outcome can support Nepal’s earthquake rehabilitation efforts and contribute to enhancing the local understanding of historic buildings.
Conserved and restored parts are maintained in good condition (middle and upper parts), and plants have grown in the parts that remain unrestored.
Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been working on a technical support and skill development project for the conservation and restoration of wall paintings and exterior walls of the temples composed of bricks, targeting the staff in the Bagan branch of the Department of Archaeology and National Museums of the Ministry of Religious Affairs and Culture of Myanmar. However, the COVID-19 pandemic and deterioration of Myanmar’s general situation have hindered our onsite work for some time. In such circumstances, we are conducting online meetings every two months to understand the status of the Me-taw-ya and Lokahteikpan temples, which are the target sites for the conservation and restoration project. We continue to provide advice for their maintenance and management by referring to the site photographs sent to us by the local staff.
The current status of the Me-taw-ya temple was reported at the meeting held on December 19th, 2021, informing that its restored parts have remained in good condition since our onsite activities were halted, which was two years ago. In the Bagan Archaeological Site, other organizations (prior to the involvement of TOBUNKEN) had repeatedly restored the joint plaster and adopted countermeasures against rain leakage. However, in most of the cases, the restoration materials were damaged within a year. Additionally, in 2021, the heavy rainfall caused disastrous damages to the structure.
For this project, we have been closely working with the local experts by listening carefully to their concerns and conducting relevant research to address them. The restoration materials introduced by TOBUNKEN have remained in good condition for 5 years, showing no damage even at the oldest parts. Thus, it is important to carefully monitor the progress after the restoration and to work on the restoration. Despite the frustration at being unable to work onsite because of the current situation, the proven effectiveness of the conservation and restoration to sustain over multiple years is a source of constant motivation for us.
Thus, while we continue to extend our full cooperation to the local staff, we remain hopeful about resuming our onsite work shortly.

Right end is HINAKO Moto’o who served as Director of the Buildings Division (1966-1971) before Dr. ITO, and IHARA Keishi who served as Director of Restoration Engineering Department (1988-1990) of the Institute on his left.)
On September 13th, a set of materials related to the administrative work for the protection of cultural properties, where Dr. ITO Nobuo served as Director of the Institute for nine years from April 1978 to March 1987, was donated to the Institute by his son, Mr. ITO Akio. Dr. ITO was a technocrat and architectural historian who led the development of cultural property protection in the postwar period. In particular, he played a central role as director of the Buildings Division of the Agency for Cultural Affairs (1971-1977) in the planning of the traditional town/village conservation system, which was newly established as a result of the revision of the Law for the Protection of Cultural Properties in 1975. He has also left a significant mark in the international field of heritage conservation by actively communicating Japan’s conservation philosophy and repair methods, and by leading “the Nara Conference on Authenticity” held in November 1994, which led to the international development of authenticity, a concept of conservation originating in Western Europe.
The donated documents are mainly primary materials related to the administration of cultural property protection and international cooperation that Dr. ITO was involved in as part of his work, as well as various materials related to research activities, private activities, and manuscripts related to architectural history and cultural properties. These materials were accumulated during the active life he led, and since they have not been systematically collected and organized, it is certain that among them are many items for which detailed information is not clear at this stage. However, from the viewpoint that it is important to make the materials available to researchers who need them as soon as possible, we plan to make them accessible to the public after classifying all the materials according to activity and sorting each item mechanically.
Among the donated materials, I would like to bring to your attention a photograph of a young Dr. ITO with his colleagues from the Buildings Division of the Committee for the Protection of Cultural Properties. Considering the appearance of Dr. ITO and the other photographs enclosed, my guess is that it was taken around 1965 when he was working hard as an architectural conservation officer at the site. The carefree demeanor and lively smiles of all in this photograph seem to indicate that the cultural properties administration was carried out during an era when Japan’s economy was booming. This fact is not easily perceivable in the formal photos from official reports.

“Dio Fluviale”, a clay statue by Michelangelo Buonarroti, the restoration of which was completed in 2017
Stucco Decorations in the 17th century (Cattedrale di Santa Maria Assunta)
The Japan Center for International Cooperation in Conservation has been conducting research and surveys investigating stucco decorations in fiscal year 2021 as part of the “International Research on Technology for the Conservation and Restoration of Cultural Heritage” program, which offers grants for research expenses. On September 11th, 2021, we held a second discussion with experts from Europe involved in the conservation of stucco decorations.
In this discussion, the use of glue made of seaweed and “Kami Susa” (binder made of “Washi” – Japanese paper – and used as part of plaster) attracted participants’ interest. These materials began to be made in order to control the plaster thickness and prevent plaster from cracking in the Edo era, when the demand for plaster walls increased. While many creative techniques and materials have been developed in Europe, where there is a long history of stucco decorations, their materials are different from those in Japan. Thus, we agreed to add the data of additives, which have been used in each country and region, as well as in different periods, as the comparative target items in our ongoing research and create a database of them.
In relation to these findings, we plan to pursue our research on how the constituents included in various additives chemically affect stucco decorations. Different materials, their natures, and the techniques used to create stucco decorations, have different impacts on the deterioration due to aging as well as how the decoration is damaged over a long period. These studies are extremely important for determining the most suitable methods for their conservation and restoration.
This research and survey began with the focus on stucco decorations. However, our deep analysis of their history enabled us to recognize the close relationship with clay statues. We plan to expand our research on the clay statues that share many common materials and creation techniques and pursue research on how to conserve them and preserve their heritage in the most suitable ways.
Practical session
The satellite venue
Tokyo National Research Institute for Cultural Properties (TOBUNKEN) and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM) have been jointly organizing “the International Course on Conservation of Japanese Paper” (JPC) since 1992. The course aims to contribute to the protection of cultural property outside Japan by disseminating the knowledge and techniques of conservation and restoration of paper cultural property in Japan to participants from around the world. Every year, we have invited 10 specialists in conservation from all over the world; however, due to the COVID-19 pandemic, we could not hold the course in 2020 and 2021. Under these circumstances, we conducted a trial experiment for the introduction of digital technology in international courses from September 8th to 15th. The trial aimed to examine the possibility of holding online courses, which are mainly composed of practical sessions such as the JPC, and to clarify problems toward the realization of the online course itself.
Before the trial, lectures were held on basic knowledge of adhesives and paper, which are major conservation materials for cultural properties on paper. The lectures were livestreamed and archived. As for the practical sessions, five simulated participants from the staff members of TOBUNKEN were divided into two groups; the one received in-person teaching and the other was given online instructions at a satellite venue. The practical sessions were led by conservators from a certified group holding the Selected Conservation Techniques on “Restoration techniques for mounts.” The participants experienced the process of restoration of a handscroll from cleaning to mounting. On the last day, the lecturers and participants discussed the effectiveness of online courses. Although the merits of the use of ICT devices were recognized, issues of doing practical sessions online, such as the necessity of having basic knowledge and experience of paper conservation in advance, the limitations of technical training through a computer, and the difficulties of troubleshooting the network environment and communication devices were highlighted.
The Urgent Statement on the Protection of Cultural Heritage in Afghanistan
Due to the dramatic change in the political situation of Afghanistan, JCIC-Heritage (Japan Consortium for International Cooperation in Cultural Heritage), which our research institute has been commissioned to manage by the Agency for Cultural Affairs, released the Urgent Statement on the Protection of Cultural Heritage in Afghanistan on 18th of August, 2021. The whole sentences are as below. JCIC-Heritage will continuously collaborate with the related organizations and make every effort for the protection of cultural heritage in Afghanistan.
“Urgent Statement on the Protection of Cultural Heritage in Afghanistan”
Due to the rapid change in the political situation of Afghanistan, there is strong concern about the likelihood of looting and destruction targeting the country’s historical cultural heritage, especially archaeological sites, and museums.
The Japan Consortium for International Cooperation in Cultural Heritage (JCIC-Heritage) is extremely concerned that the irreplaceable cultural heritage of Afghanistan is in great danger.
The consortium was established to promote collaboration among related organizations and experts in Japan and facilitate a greater Japanese role in international cooperation in the field of cultural heritage protection. Since 2001, activities in Afghanistan have been a critical pillar in the history of Japan’s international cooperation in cultural heritage, which have achieved significant results by cooperating with Afghanistan, other countries, and international organizations.
It is widely recognized that cultural heritage is a common treasure that tells the history of humanity. Cultural heritage also plays an important role as a source of national unity and identity, as well as facilitating regional and national development. Wishing to prevent any attacks on cultural heritage and mitigate its illicit transfer, we urge all parties and individuals concerned to act in a calm and considered manner. We also would like to share our concerns with the international community.
JCIC-Heritage hereby express our strong resolution to continue offering support for the protection of Afghanistan’s cultural heritage. We hope that the people of Afghanistan will be able to live in safety and security, and that the current situation will be stabilized as soon as possible.

The 29th Seminar: "Preservation and Transmission of Information on Cultural Heritage”
The 29th Seminar in session
Today, the progress of recording technology, including digital archives, has enabled storing the information on cultural heritage in databases and interactive efforts have been initiated to consistently collect (specific) information unique to different regions around the world.
In order to discuss appropriate ways of retaining and passing down information related to cultural heritage and possibilities of future international cooperation in this field, JCIC-Heritage (Japan Consortium for International Cooperation in Cultural Heritage, which our research institute has been commissioned to manage by the Agency for Cultural Affairs), held a webinar on August 9, 2021, titled “Retention and Succession of the Information associated with Cultural Heritage~For Whom and What Purpose~”.
SAITO Reiko (National Museum of Ethnology) gave a lecture titled, “Info-Forum museum and Utilization of Ainu Ethnic Materials.” KUBOTA Hiromichi, Head of the Intangible Folk Cultural Properties Section, presented a lecture titled “Recording and Utilization of Information Related to Intangible Cultural Heritage.” HAYASHI Kengo (University of Tokyo) delivered a lecture titled “40 Years of the Asian Modern Architectural Heritage Database: Its Development, Transformation, and Challenges.” In the following panel discussion, the possibility of international cooperation through the creation of databases on cultural heritage and the type of information to be recorded in them was discussed between the panelists with KONDO Yasuhisa (Research Institute for Humanity and Nature) as the moderator.
Nowadays, more people with various backgrounds have concern regarding how to retain information related to cultural heritage and to whom it should be inherited. In addition, the methods and objectives for those matters have been diversified. JCIC-Heritage will continue to collect and disseminate relevant information.

Stucco decoration in the Ticino style
Stucco decorations are distinct in their form and purpose, and they can be found in various parts of the world. The Japan Center for International Cooperation in Conservation began research and surveys investigating stucco decorations in fiscal 2021 as part of a the “International Research on Technology for the Conservation and Restoration of Cultural Heritage” program, which offers grants for research expenses. The purpose of this program is to track how stucco decorations have been propagated to different regions as they repeatedly evolve and deteriorate in quality, and to understand and verify how efforts are being made to conserve and restore these decorations in different countries today. On May 29, experts involved in the conservation of stucco decorations, mainly in Europe, participated in an online discussion.
In an exchange of opinions, the topic of stucco decorations in the Ticino region of Switzerland were introduced, which laid the foundation for stucco decoration in Europe from the Mediterranean coastal regions and from the 16th to 18th centuries. From Japan, we introduced what we have learned from our research so far, including kote-e (plaster relief paintings) made using traditional plaster, the stucco techniques and materials that were popularized alongside pseudo-Western-style architecture, which imitated Western architecture from the end of the Edo period to the Meiji period, and also the current maintenance status of these works.
Participating experts expressed surprise that many common points can be found in techniques and materials across different countries and time periods. They also agreed to jointly study methods for conservation and restoration aimed at improving the current situation, as there are many similarities regarding maintenance and management issues.
In the future, while continuing with our research surveys in Japan, we will recruit overseas research collaborators, and expand the scope of our research domains. In addition, we would like to accumulate information through exchanges of opinions and the sharing of research results, deepen understanding of stucco decorations, and opening a forum for the consideration of how to both conserve them and pass them down to future generations.
Unpacking the artwork
A large number of works of Japanese art are possessed by museums overseas. However, most of them have no specialists who can restore works of Japanese art and no appropriate measures have been taken against their deterioration or damage. In the Cooperative Program for the Conservation of Japanese Art Objects Overseas, we investigate Japanese art objects overseas, identify those with high cultural values and needing to be restored more urgently than others, bring them back to Japan through consultation with the museums that possess them, restore them under the thoroughgoing measures in Japan, and send them back to them after the completion of the restoration work.
Montreal Museum of Fine Arts, Canada’s oldest art museum, currently possesses more than 45,000 works of art after having relocated or expanded since it was inaugurated in 1879. They include a large number of Japanese works. Based on the results of a local survey conducted in 2018, we decided to restore two works: Kumano Honjibutsu Mandala (color on silk; a hanging scroll), and Byobu Screens Featuring the Thirty-six Poetesses (color on paper with gold leaf; a pair of six-panel folding screens) that are housed in the museum.
Though a museum courier was unable to accompany the works in transit due to the impact of the COVID-19 pandemic, they were safely imported into Japan in March 2021. We will start a series of the restoration processes from documentation, including a current situation survey and taking a high-definition photo.
A glimpse of the online international training course
The Japan Center for International Cooperation in Conservation provided an online international training course, “Documentation of Cultural Heritage by Three-dimensional Photogrammetry,” on November 12th and 25th, 2020, jointly with the Japanese Centre for South Asian Cultural Heritage (JCSACH), a non-profit organization. It was aimed at promoting active incorporation of digital data as a method of international cooperation in the field of cultural heritage post COVID-19. Three-dimensional photogrammetry is a technique to create a 3D model of the exact shape of an object on a computer from photographs of the object taken from various angles by a digital camera. Since 3D models can be created using familiar equipment, such as compact digital cameras and smartphones, it is becoming popular in cultural heritage sites as a highly practical recording method. For this training course, researchers and practitioners who are responsible for the conservation of cultural heritage in four countries were invited. These included Cambodia, Nepal, and Iran, where Tokyo National Research Institute for Cultural Properties is carrying out international cooperation programs, and Pakistan, with which JCSACH enjoys close ties.
Mr. NOGUCHI Atsushi, the Director-cum-Secretary General of JCSACH, who is a leading expert in 3D photogrammetry technique in the field of archaeology, served as lecturer. In the first lecture, the trainees learned the principles of 3D photogrammetry, how to take photographs to be used for photogrammetry, and basic operation of the software. They worked on creating their own 3D models during a week of independent practice after the first lecture. In the second lecture, the trainees presented the models they had created and learned more advanced techniques, such as how to create cross-sectional views from the models.
A total of 24 researchers and practitioners from Cambodia, Nepal, and Pakistan participated in the online training course. It was unfortunate that the Iranian participants were not able to take part due to a problem with the Zoom connection, but they were provided with the course materials. Most of the trainees had never had any prior experience with 3D photogrammetry. However, they were eager to ask questions. Further, in the post-participation survey, they shared their own ideas on how to use 3D photogrammetry data, such as for recording remains at restoration sites, or for museum exhibitions.
Once 3D photogrammetry becomes a common documentation method in every country and sharing 3D information on cultural heritage becomes possible remotely, we will be able to see new developments in international cooperation projects in the future.
