The historic house under investigation in the medieval settlement of Kirtipur
Almost 8 years have passed since the Gorkha earthquake in 2015 that caused devasting damage in Kathmandu valley. Many historic buildings are undergoing reconstruction, including those with “Kathmandu Valley World Heritage Site” status. While the rehabilitation of these recognized heritage sites is being carried out with public attention, the historic buildings that are not legally protected, especially privately owned properties, are decreasing in number due to reconstruction or demolition without any recognition of their heritage value.
Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been working to support the establishment of a network for conservation of historic settlements of Kathmandu valley, in collaboration with experts and governmental officers in Nepal, since just after the Gorkha earthquake and continuously during the pandemic. This series of dialogues led us to launch a new project for the conservation of a damaged historic house in Kirtipur as a cooperative project between Kirtipur municipality and TOBUNKEN.
Built in traditional Newar style, the target house, a historical landmark of the town, is located within the area of the World heritage tentative listing, “Medieval settlement of Kirtipur.” Although the building is currently being used for residential purpose, it is said that it used to be a part of the former royal palace complex of Kirtipur in old times. A square with a historic pond surrounded by this house and a nearby medieval temple together comprise one of the symbolic historical landmarks of the old town of Kirtipur.
In the first joint survey, conducted from October 11 to 16, 2023 with the aim of collecting basic information on the building, the project team carried out a measurement survey, investigation on the transition of the building, and interview surveys with residents on the ownership relationship, lifestyle of residents, family history, and intentions for future utilization of the building. Further discussions will be held with related stakeholders regarding the possibilities of the future utilization of the house and issues to be solved to enable its realization.
Many countries, including Japan, share common challenges on the conservation of historic buildings that are not legally protected. Through this project, together with Nepalese experts, we will exchange knowledge through dialogue with the aim of establishing a process for conservation and utilization of historic buildings that would be compatible with the Nepalese cultural context.

The Japan Center for International Cooperation in Conservation (JCICC) is currently undertaking a research project abroad that focuses on advanced initiatives in the conservation of modern architectural heritage. This project, titled “Overseas Case Study on the Protection and Transmission of Contemporary Architecture,” is commissioned by the Agency for Cultural Affairs. From September 18 to 22, we conducted a field survey in Taiwan as a part of this project.
In Taiwan, the 2000 Act on the Promotion of Private Sector Involvement in Public Construction, and the 2002 National Development Priority Plan, which included the promotion of creative industries, led to the proactive conservation and transformation of architectural and industrial heritage with the introduction of private sector vitality from the 2000s to the 2010s. In this survey, we visited two of the “Cultural and Creative Industrial Parks” (hereafter referred to as “Creative Parks”) in Taipei City led by the Ministry of Culture (until 2011, the Cultural Development Commission) and interviewed their management bodies about the current status, challenges, and prospects for the management of heritage buildings as business facilities.
The Huashan 1914 Creative Park utilizes the facilities of a former government-run liquor factory established in 1914, while the Songshan Creative Park makes use of facilities from a former government-run tobacco factory established in 1937. The Huashan park is managed by the Taiwan Cultural-Creative Company Limited, funded by several private companies, while the Songshan park is operated by the Taipei Cultural Foundation, umbrellaed under the City of Taipei. Despite having distinct organizational structures and operational policies, both parks are financially independent and share a common goal of enhancing public awareness of the Creative Park as a unique destination. This objective helps the parks maintain their operational stability and generate profits. However, an issue arises from the fact that only the utilization aspect of architectural conservation has been entrusted to private-sector entities, leading to various misunderstandings between their approach and the administration responsible for preservation of the architectural heritage.
We also visited the Bureau of Cultural Heritage (BOCH) of the Ministry of Culture to conduct interviews on topics including the evaluation of the Creative Park project. The BOCH has analyzed the reasons why Creative Parks have not progressed as originally planned, as stumbling blocks have arisen such as the fact that preservation is the responsibility of the government while utilization is the domain of the private sector, and the project has already started to change course. Since 2017, a ‘Reconsolidation of Historical Time and Space’ plan has been underway, which links the comprehensive management and utilization of cultural heritage linked to the land and people’s memories to policies for developing social infrastructure.
The JCICC will continue to conduct field surveys in Europe with the cooperation of relevant organizations and experts in the target countries and compile the results into a final research report, together with the results of bibliographic study into the relevant legal systems in each country or region.
Panel talk on the conservation of the Tutankhamun collections
Speakers in this symposium
Tokyo National Research Institute for Cultural Properties (TOBUNKEN) was entrusted with an opening support project for the Grand Egyptian Museum by JICA from 2008 to 2016, and conducted seminars on capacity development and technical instruction for the conservation of museum collections.
In this context, we organized a symposium titled “Grand Egyptian Museum Now: Preserving the Treasures of the Pharaohs 2023,” which aimed to widely release the opening support projects conducted by the Japanese mission, including our entrusted project, ahead of Museum opening. This symposium was co-organized by the Grand Egyptian Museum and JICA on August 6, 2023 at the Heiseikan Auditorium in Tokyo National Museum. We invited both Mr. Atef Moftah, the general supervisor of Grand Egyptian Museum Project and Surrounding Area, and Mr. Eissa Zidan, the general manager of the first aid conservation and transportation of the artifacts, to this symposium.
The Grand Egyptian Museum, which is located next to the Great Pyramids area, is attracting attention before its opening as the largest museum in the world exhibiting collections from a single civilization. In the symposium, Mr. Moftah gave the keynote lecture and introduced the whole museum and the Tutankhamun collection room. Following that, Prof. YOSHIMURA Sakuji, the president of Higashi Nippon International University, and Mr. Zidan both made presentations on the latest outcomes on the second boat of Khufu, which the Japanese mission is currently restoring for display in the annex building. Additionally, the researchers responsible for the conservation of Tutankhamun’s objects presented their results, and a panel discussion was held on the theme of expectations for the Grand Egyptian Museum.
This symposium became a great opportunity to showcase the achievement of international cooperation to date, because we not only introduced the situation of the museum before the opening, but also all of the Japanese support in one place. Contents of the symposium will be released on the TOBUNKEN home page soon.
Participants taking pictures for 3D digital documentation
The３D documentation using Agisoft Metashape and iPhone Scaniverse has recently been introduced, and is rapidly coming into use. The introduction of this technology can not only reduce working time, but also makes it possible to document cultural heritage with very high precision.
The Japan Center for International Cooperation in Conservation arranged a three-day workshop on 3D digital documentation for experts who are working abroad from July 15 to 17, 2023. Dr. NOGUCHI Atsushi from Komatsu University was invited as the lecturer. The main aim of this workshop was to spread 3D documentation techniques among the foreign experts through the Japanese experts who attended the workshop.
Twenty-five specialists with a variety of backgrounds in areas such as archaeology, conservation science, and conservation architecture joined this workshop and studied how to make 3D models using Agisoft Metashape and iPhone Scaniverse.
Exterior view of St Michael's Church
Cleaning tests for soot stains
Cappadocia, located in Central Anatolia, Republic of Turkey, was added to UNESCO’s World Heritage List in 1985 as Göreme National Park and the Rock Sites of Cappadocia, as a result of long-term erosion of the tuff plateau. More than 1,000 rock churches and monasteries had been built, and mural paintings were painted on the inner walls of these churches and monasteries.
Last year, a preliminary survey was conducted with Ankara Haji Bayram Veli University to establish a joint research project on the conservation and restoration of cultural properties, and as a result, it was decided to target the mural paintings in St, Michael’s Church (in the Keslik Monastery). In response, we visited the site from June 15 to 22, 2023 and conducted a survey aimed to establish a research plan. Research issues were then identified, such as the removal of soot stains covering the mural paintings surfaces and the conservation treatment of plaster layers that had detached from the bedrock support.
In the future, while sharing research issues with local experts, we will continue our activities to contribute to the conservation and restoration activities of cultural heritage in the Republic of Turkey.
Kheni village in Trashiyangtse province, composed of vernacular stone masonry houses
A house of typology unique to Merak district in Trashigang province
Measurement survey of a timber hut
Since 2012, the Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been continuously engaged in research on vernacular houses in Bhutan, in collaboration with the Department of Culture and Dzongkha Development (DCDD, formerly the Department of Culture, renamed recently upon restructuring), Ministry of Home Affairs, Royal Government of Bhutan. The DCDD promotes a policy of preserving and utilizing vernacular houses by integrating them into the legal protection framework of cultural heritage, while TOBUNKEN supports the initiative from academic and technical aspects.
Previously, our study focused on rammed earth houses commonly seen in the western area of the country. This year, we began a survey on stone masonry houses widely located in central and eastern areas, with the financial support of a JSPS Grant-in-aid for Scientific Research. The first survey mission under this scheme was implemented from April 25 to May 5, 2023.
Our group, comprising four dispatched staff members of TOBUNKEN and two from DCDD, jointly carried out a field survey in the five provinces spanning from Trashigang in the east to Bumthang in the central region. We observed stone masonry houses that appeared to have been built during earlier periods than other traditional houses in the target area, based on prior information collected by DCDD, and surveyed 14 houses in a detailed manner including taking measurements and interviewing the residents. Other than three cases of large-scale, three-storied residences of the ruling class, all were originally very small houses of one or two stories. In the Merak district of Trashigang, where a nomadic ethnic group lives, a unique typology of one-story houses without cattle sheds was widely observed.
Based on knowledge and information obtained during this survey mission, we plan to extend the target area and conduct more detailed investigations of the old houses we had already identified. In addition, since transition and locality of the housing type reflects change and difference of lifestyles, we feel a need to put more focus on these areas in the future. We will continue in our effort to further accelerate cooperation to prevent the loss of precious heritage against the trend that the numbers of vacant and degraded houses are increasing.
The East Gate after completion (photo taken by drone)
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. In November 2022, the two parties completed a three-year collaborative restoration project to dismantle and restore the East Gate of the temple. From May 6 to 18, 2023, TOBUNKEN dispatched our group, consisting of two staff members, to the site to record the completion status of the restoration and conduct additional research for the preparation of a final report on the restoration work to be published this year.
For documentation of the completion status, in addition to (1) architectural photography, (2) architectural drawings and (3) a digital 3D model of the East Gate were created. The digital 3D model with dimensional information was generated from some 1,000 images of the building taken from all directions with a single-lens reflex camera and two drones (Mavic mini), using a technique known as “3D photogrammetry.”
Supplementary survey work for preparing the final report included (1) partial revision of the temple layout drawings, (2) photographic documentation of pediment decorations, and (3) a comparative study to analyze the architectural features of the East Gate. For the comparative survey, we visited 10 other temples among the Angkor Monuments that were constructed during the same period as Ta Nei Temple to examine their architectural styles and decorations.
In addition, on-site discussions were held with APSARA representatives regarding the future implementation plan of the Ta Nei Temple conservation project.
We plan to conduct archaeological excavation and architectural survey of the Entrance Terrace to the Causeway, publish a final report, and organize a symposium to commemorate the completion of the East Gate restoration work in the second half of this fiscal year. We will keep you posted on the progress of our project!

Presentation by Mr. Ivgin
Visiting NABUNKEN
The Japan Center for Institutional Cooperation accepted a visiting researcher, Mr. Ilkay Ivgin, from the Ministry of Culture and Tourism in the Republic of Turkey from April 10 to May 31, 2023. Mr. Ivgin studies comparative research on the cultural property laws in Turkey, Japan, and Italy. During his stay, he undertook research especially on the administrative system of buried cultural property in Japan. Moreover, he collected information on cultural heritage disaster risk management to reconstruct damaged cultural properties and museums affected by the great earthquake in Turkey and Syria in February 2023.
Our center provided collected knowledge on the protection systems for cultural properties and introduced related documents, and also accompanied Mr. Ivgin on visits to the organizations and institutions that work to investigate and manage cultural properties. Acceptance of this visiting researcher at this time was a good opportunity for us to learn about the current situation of Turkish cultural heritage as well as to understand more deeply the Japanese administrative system for buried cultural property and its tasks.
A comment from Mr. Ivgin is included below.
“Within the scope of my Ph.D. thesis titled "Examination of Legal Legislation in the Preservation of Archaeological Artifacts in Türkiye and Legal Arrangement Suggestions for Standardization", which I am still working with the Department of Conservation and Restoration of Cultural Heritage at Ankara Hacı Bayram Veli University. In my Ph.D. thesis, the Japanese legislative system for the protection of cultural assets constitutes an important part of my work.
I am very grateful for their support of my work on the subject of my thesis at the Tokyo National Research Institute for Cultural Properties, where I began my research within the scope of this thesis. I would like to thank the staff of the Tokyo University, Ancient Orient Museum, Tokyo National Museum, Chiba-City Archaeological Research Center, Tokyo Metropolitan Archaeological Research Center, Archeology Institute of Kashihara, Nara National Research Institute for Cultural Properties and Agency for Cultural Affairs for their support.”

The Tokyo National Research Institute for Cultural Properties organized a Cultural Heritage Kids Workshop as a program targeting elementary students to promote an interest in cultural heritage to the next generation, who will inherit the cultural heritage in the future. This workshop was planned and conducted by Ms. YAMADA Ayano, an Associate Fellow of the Japan Center for International Cooperation in Conservation, and held on the morning of April 30, 2023. The theme of the first workshop was “Pyramid.” In total, 90 people gathered at the workshop: 33 groups including 36 elementary students.
In the first half of the program, lectures on the history of the pyramids and the livelihoods of their builders were presented by two lecturers, Ms. YAMADA and Ms. FUKUDA Lisa, who is currently attending a doctoral course at the graduate school of Waseda University. By including topics that are not mentioned in the school textbooks but were revealed by archaeological and historical studies, we surmised that the children could imagine being close to the ancient civilization by comparing it with their own daily and school life.
In the second half of the program, we provided two bodily sensation programs outside the classroom lectures. One was an experience in which the participants watched a VR of the pyramid site wearing VR goggles. The other was an experience attraction in which they passed through a model corridor or into a model sarcophagus reproduced at 1:1 scale, watching a virtual tour inside the great pyramid. The materials used in the workshop are available to watch and experience at home. We aimed for effective retention of learning, by providing an opportunity of experience that the children will continue and repeat many times after the limited time of workshop.
Positioning initiatives for the next generation, such as this workshop, as an extension of research, we intend to plan a second Cultural Heritage Kids Workshop.
Prof. Suzanne Bickel making a presentation.
The Tokyo National Research Institute for Cultural Properties and the Institute for the Study of Ancient Civilizations and Cultural Resources at Kanazawa University co-organized a special lecture, “100th Anniversary of the Tutankhamun Tomb Excavation: Current Excavation in the Valley of the Kings” on April 30, 2023, presented at the Auditorium of Heiseikan in the Tokyo National Museum. This special lecture was planned to announce the latest results of excavations in the Valley of the Kings, which is the necropolis of Ancient Egypt, commemorating the 100th Anniversary of the Tutankhamun tomb excavation.
We invited Prof. Suzanne Bickel, who heads the Kings’ Valley Project, from Basel University in Switzerland for this special lecture. She discovered the 64th tomb there in 2011-2012, and is one of the researchers who led the study concerning the kings’ necropolis. She presented the archaeological and anthropological research outcomes on Kings’ Valley tomb No. 40, in which family members of Amenhotep III and court women living in the eighteenth dynasty in the New Kingdom were buried, which was investigated by the Kings’ Valley Project from Basel University. Moreover, Dr. KONDO Jiro, a professor emeritus at Waseda University, who excavated the tomb of King Amenhotep III, and Dr. KAWAI Nozomu, a professor at Kanazawa University, who studied about the mysterious Queen Neferneferuaten of the eighteenth dynasty, also made presentations.
In total, 275 people attended the special lecture, and we provided highly specialized archaeological content based on excavation research results to them. We will continue to hold similar lectures to actively broaden the research achievements.
Interview at the Dutch Cultural Heritage Agency
Field survey at the archaeological site of Hedeby in Schleswig
Since FY 2007, Japan Center for International Cooperation in Conservation has been collecting and translating foreign laws concerning the protection of cultural properties and has so far published 27 volumes covering 16 Asian and 6 European countries. The project is intended to be Japan’s contribution to international cooperation in the field of cultural heritage protection and provide a reference for reevaluating the system used by Japan to protect its cultural properties. A field survey was conducted in the Netherlands, the target country for the current FY, and in Germany, the target for last FY. The survey was conducted from March 3 to 13, 2023.
Recently, in the Netherlands, there has been a discussion on the need to include heritage protection in land use and environmental preservation planning. A new Environmental Planning Law, integrating the existing related laws, will come into force on January 1, 2024. This law will introduce an environmental permit system for the use of cultural heritage sites with basic provisions for municipal environmental planning and similar purposes. This legislative amendment is constructed on the foundation of various agreements of the Council of Europe, such as the Valletta Treaty of 1992 on archaeological heritage and the Florence Convention of 2000 on landscapes.
On the other hand, in Germany, each of the 16 states have their own laws for protection of monuments. There are also slight differences in the protected objects, and only three states have regulations on cultural landscapes. Schleswig-Holstein, the northern state I visited this time, is one of them, but cultural landscapes are not yet in operation. A similar provision can be found in the Federal Nature Conservation Law. However, the German government has not signed the Florence Convention, which is a topic of great debate within the country.
One of the objectives of the Florence Convention is to recognize landscapes that express the “form” of Europe, woven by diverse histories, cultures, and nature, as a common heritage of the EU member States, and to protect them appropriately. Certainly, landscape protection is deeply linked to global issues such as climate change and sustainability that cannot be resolved by a single country. In future research, I think it will be even more important not only to translate laws, but also to specifically clarify the organic relationship between cultural properties and the comprehensive framework that surrounds them.

Istria is a peninsula that is largely located in northwestern Croatia, with some parts governed by Slovenia and Italy. Istria has a history of frequent changes in rulers: the Roman Empire in ancient times, the Venetian Republic in the Middle Ages, and the Habsburg Empire in modern times.
In this region, the practice of beautifying churches with wall paintings flourished from the Middle Ages to the Renaissance, giving birth to numerous remarkable works. Unfortunately, the need to preserve this heritage was recognized only in the late 19th century in the wake of the activities of the Austro-Hungarian Empire’s Commission for Research and Conservation of Art and Historical Monuments. Later on, in the 20th century, after several wars and conflicts, the political situation finally calmed down after 1995 and the Croatian government established the Croatian Conservation Institute for cultural heritage. This led to a joint investigation by the Institute and the Archaeological Museum of Istria, and the term “Istrian-style wall painting” was coined as a general term for murals unique to this region.
From March 1-7, 2023, with the assistance of Dr. Sunčica Mustač of the Historic and Naval Museum of Istria and Associate Professor Neva Pološki of the University of Zagreb, we visited about 20 major churches in Istria to conduct field research on the wall paintings. In the process, technical cooperation was sought for the creation of a data archive on production techniques and conservation conditions, as well as for the study of conservation and restoration methods for the future. In the Istria region, there are approximately 150 surviving church wall paintings have been confirmed to exist. With the desire to pass on this irreplaceable cultural heritage to future generations, we will work to establish international collaboration while building networks with experts in related fields.
Courtesy visit to Rector Calcagnini
Campus Facilities
Italy is home to numerous cultural heritage sites and has been at the forefront of the conservation and restoration efforts undertaken to maintain these sites. The Department of Pure and Applied Sciences of the University of Urbino Carlo Bo is one the educational institutions in Italy that has made many contributions in the field of conservation science.
Recently, the Tokyo National Research Institute for Cultural Properties concluded an agreement with this department to enter into research cooperation for the conservation and restoration of cultural heritages. The content of the agreement is comprehensive, targeting cultural properties around the world. The agreement aims to foster cooperation in scientific investigation and in development of techniques and materials for the formulation of conservation and restoration plans. Furthermore, a mutual exchange of researchers through events such as workshops is envisioned.
On February 17, 2023, I visited the University and exchanged opinions with Rector Giorgio Calcagnini regarding the future cooperation.
Also, under the guidance of Prof. Maria Letizia Amadori, Department of Pure and Applied Sciences, I toured the university facilities and had the pleasure of learning about an analytical study on cultural heritage preservation that is currently being undertaken.
In the future, through research cooperation that utilizes the expertise of both institutions, we hope to go beyond simply collecting analytical data, and develop activities that will lead to concrete preservation of cultural heritages.
Damaged cultural properties in the collection
First aid treatment
Since 2017, the Tokyo National Research Institute for Cultural Properties has been carrying out a cooperative project to improve the conservation management system for cultural properties in the Republic of Turkey. On February 6, 2023, an earthquake centered in southeastern Turkey occurred, causing extensive damage mainly in Turkey and the Syrian Arab Republic, and affecting the state of preservation of cultural heritage. Obviously, for the time being, humanitarian aid should be prioritized. However, in the near future, it is anticipated that international support will also be needed for conservation and restoration of cultural properties.
Meanwhile, Central Italy suffered a series of major earthquakes in 1997, 2009, and 2016, and recovery efforts for damaged cultural heritage are still ongoing. The investigation was conducted from February 13 to 16, 2023, in the regions of Marche and Umbria, with the aim of learning how to respond to possible future contingencies, as well as to consider future support for Turkey and Syria, which have similar cultural heritages. Located in the city of Spoleto, the Sainte Quiord Art Collection was built following the 1997 earthquake as a shelter for cultural properties in the event of a natural disaster and as a place to provide first aid.
The facility still houses approximately 7000 pieces of damaged cultural properties, and emergency measures are being taken by nationally certified conservators.
Through repeated experience, Italy has developed an organizational structure and procedures for rescue operations immediately after a disaster and for subsequent handling of the situation. There are many things to be learned from countries that continue to make advanced efforts in disaster recovery and reconstruction activities related to cultural properties. We would like to continue our research and use the learnings in our future activities.
Flyer for the 32nd Research Meeting
The 32nd Research Meeting
The Japan Consortium for International Cooperation in Cultural Heritage (the Tokyo National Research Institute for Cultural Properties is entrusted with the administration of the secretariat by the Agency for Cultural Affairs, Government of Japan) held its 32nd seminar, “Past and Future of International Cooperation in Cultural Heritage in Central Europe” via webinar on January 28, 2023.
In considering the severe damage that Russia’s invasion of Ukraine had on international cooperation for cultural heritage, it is necessary to know the region’s geographical and cultural characteristics, and to give due consideration to its historical background. From this perspective, the program’s purpose was to learn about Central, Eastern, and Southeastern European, including Ukraine, and to review Japan’s international cooperation activities related to cultural heritage in the region while considering how future cooperation should be conducted.
Mr. SHINOHARA Taku (Tokyo University of Foreign Studies) presented “The Historical World of Central Europe,” MAEDA Koki (Japan Consortium for International Cooperation in Cultural Heritage) presented “International Assistance to Central Europe and Japan’s International Cooperation,” Ms. SHIMADA Sachi (Jissen Women’s University) presented “Cultural Heritage Protection and International Cooperation in Serbia,” and Mr. MIYAKE Riichi (Tokyo University of Science) presented a report titled “Historical and Cultural Heritage in Romania and its Protection’.
Following these lectures, Mr. KINBARA Yasuo (Chairman of the European Subcommittee, Japan Consortium for International Cooperation in Cultural Heritage/ Tokai University) as a moderator and the speakers actively discussed the importance of international cooperation based on mutual understanding and the need for developing local human resource and building organizational structure to link to sustainable cultural heritage protection. The need for developing local human resource development, building organizational structure, and supporting sustainable cultural heritage protection was pointed out, and active opinions were exchanged. For details on the seminar, please see the consortium’s webpage below.

Research at the Bahrain National Museum
The Tokyo National Research Institute for Cultural Properties has been cooperating with the excavation survey and maintenance of historical sites in the tombs of Bahrain for many years. When we visited the site in July 2022 and met Salman Al Mahari, Director of the Bahrain National Museum, he asked us to help protect the historical Islamic tombstones that remained in the mosques and cemeteries. Currently, approximately 150 historical Islamic tombstones remain in the country, but they are deteriorating due to salt damage and other factors.
In response to this request, as the first step of new cooperative activities, 3D measurements were taken of tombstones in the Bahrain National Museum’ collection and Al-Khamis Mosque from February 11 to 16, 2023. Structure-from-Motion/Multi-View-Stereo (SfM-MVS), a technology that creates 3D models from photographs, was used for photogrammetry to complete measurements of 20 units in the Bahrain National Museum and 27 units in the Al-Khamis Mosque’s collections. Tombstones made of limestone are highly compatible with photogrammetry, and from the 3D models created, the inscriptions on the tombstones can be seen much more clearly than from photographs or with the naked eye. These models will be made publicly available on a platform that can be accessed widely both domestically and internationally and will be used as a database for tombstones in the future.
In the following fiscal year and beyond, we plan to further expand the scope of our 3D measurement work to other cemeteries in Bahrain.

Scene of discussion at the seminar
Since 2018, the Japan Center for International Cooperation in Conservation has been hosting the World Heritage Seminar, which aims to transmit information and facilitate an exchange of opinions about the world heritage system and its trends in the country. In FY 2022, redefining it as Re-question on Landscape as Cultural Property, it focused on “landscape” as a tangential point between UNESCO’s sites based on an idea of environmental and territorial preservation, and the Japanese concept of cultural property protection, which recently has been trying to upgrade the “old-style” protection (i.e., protection of a single building or site) to a wider, areal one. For the past two years (FY 2020 and 2021), due to COVID-19, we have had no choice but to conduct it online; however, this year, we held it in-person on December 26th, 2022, at the Tokyo National Institute for Cultural Properties (TOBUNKEN), limiting participation to 50 persons.
Mr. NISHI Kazuhiko (Agency for Cultural Affairs) started with a presentation on Trends on World Heritage. Thereafter, KANAI Ken (TOBUNKEN) explained the purpose of the seminar. In Part I, Ms. EDANI Hiroko (Nara National Institute for Cultural Properties) and MATSUURA Kazunosuke (TOBUNKEN) made two presentations from a research perspective titled Characteristic of Japanese Cultural Landscapes and World Heritage Sites as Landscape: Area Setting and its Basis Law, respectively. In Part II, Mr. UENO Kenji (Hirado City) and Mr. NAKATANI Yuichiro (Kanazawa City) made presentations from an administrative perspective about the Possibility of a Landscape Protection through Cooperation and Town Planning to Revive the Cultural Landscape Value in Kanazawa. Thereafter, all speakers discussed the landscape positioning within the Japanese heritage protection system.
Through presentations and discussions, it was clarified that, while the landscape as cultural property is accepted conceptually and institutionally in a limited manner in Japan, it is widely integrated in the land use policy involving urban planning, environmental preservation, and agricultural policy, as is done in Europe. It was also pointed out that cultural property protection and urban planning in Japan have taken separate steps that drastically delay its overall protection even today. The Center will continue to research on the international heritage protection system, including the theme of “landscape,” which is a complicated problem in Japan.
Dilmun Burial Mounds remaining in Bahrain
Speakers and participants of the symposium held in Tokyo, Japan.
The Kingdom of Bahrain in the Middle East has many interesting cultural heritage sites, despite being a small island country of the size of Tokyo’s 23 wards and Kawasaki City combined. It is known that Bahrain was called Dilmun, and prospered by monopolizing the maritime trade connecting Mesopotamia with the Indus region, approximately 4,000 years ago. As many as 75,000 burial mounds were built during that period only in Bahrain, which have attracted the attention of many researchers since the end of the 19th century. The Dilmun Burial Mounds were inscribed on the World Heritage List in 2019.
The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been cooperating on the site management and excavations of the Dilmun Burial Mounds for a long time. From FY2022, we began cooperating on the conservation of historic Islamic gravestones in Bahrain.
The year 2022 marks the 50th anniversary of diplomatic relations between Bahrain and Japan. TOBUNKEN held the international symposia on Archaeology and International Contribution: Japanese Cooperation for the Protection of the Cultural Heritage in Bahrain (on December 11th, 2022 at TOBUNKEN) and the Latest Discoveries of Arabian Archaeology (on December 14th, 2022, at Kanazawa University), co-sponsored by the Institute for the Study of Ancient Civilizations and Cultural Resources of Kanazawa University. The Director of Archaeology and Museums of Bahrain, heads of Denmark, France, and British missions that conduct excavations in Bahrain, and archaeology and conservation science experts in Japan, gathered for the symposia.
The history of each country’s excavations in Bahrain and the excavation, conservation, and restoration activities of Japanese experts were introduced at the symposium in Tokyo. The latest excavation survey results for each mission were introduced at the symposium in Kanazawa.
TOBUNKEN plans to continue cooperating for the protection of cultural heritage in Bahrain in various ways.

The Tokyo National Research Institute for Cultural Properties (TOBUNKEN) has been working with the Authority for the Protection and Management of Angkor and the Region of Siem Reap (APSARA) on the cooperation program for the Ta Nei Temple in the Angkor Archaeological site in Cambodia.
Angkor was inscribed on UNESCO’s World Heritage List in 1992. This led to comprehensive international support and cooperation from other countries, including Japan, which covers not only the conservation and restoration of the archaeological sites, but also various other fields like the formation of management systems, including human resource development, tourism development, and planning and infrastructure improvement for sustainable development of the surrounding regions. Angkor has been established as a top international tourist destination and became one of the most important sources of foreign currency revenue for the Cambodian economy. At the same time, it was highly praised as a successful model of international cooperation on the protection and utilization of World Heritage Sites, despite facing various challenges till date.
On the early morning of December 14th, 2022, I attended a ceremony commemorating the 30th anniversary of Angkor’s inscription on the World Heritage List. The solemn ceremony, held in front of the entrance causeway to the Angkor Wat Temple, started with Buddhist sutra chanting by many priests, where the APSARA dance was also performed. A poster exhibition on international cooperation history, including TOBUNKEN’s projects, was also held at the event.
On the following two days, the 36th Technical Session and the 29th Plenary Session of the International Coordinating Committee for the Safeguarding and Development of the Historic Sites of Angkor and Sambor Prei Kuk (ICC-Angkor) were held successively in Siem Reap City. For the previous two years, these regular meetings were held online due to the COVID-19 pandemic. This year, we finally managed to hold the meeting in person, with related experts and institute representatives both from and outside of Cambodia. The progress on many programs was reported and shared, and we revived the relationship among the related parties from various countries. I deeply appreciate the fact that in-person meetings as precious opportunities have finally resumed.
Noriutsugi
Neri is extracted from noriutsugi bark. The yellow part of the tree is where bark has been removed.
Discussion meeting in TOBUNKEN
Washi (Japanese traditional paper) is used for the restoration of cultural properties and for traditional crafts. It is well known that washi is made of fibers extracted from plants such as kōzo (Broussonetia kazinoki x B. papyrifera) and ganpi (Diplomorpha sikokiana). However, it is not widely known that neri, a dispersant, is also essential for washi making. Adding neri disperses the fibers evenly in water, producing smooth and beautiful washi. Without the addition of neri, the fibers are not evenly dispersed, and washi made without neri has poor formation.
Including washi most cases of industrial mass paper manufacturing use synthetic compounds such as polyethylene oxide as neri. Traditionally, neri is made from mucilage extracted from plants such as tororoaoi (Abelmoschus Manihot) and noriutsugi (Hydrangea paniculate). At present, neri extracted from tororoaoi or noriutsugi is still most suitable for thin washi making. It is also widely used for washi-making for cultural property restoration. However, the sustainable and stable supply of these raw materials, especially noriutsugi, becomes increasingly difficult. This is because noriutsugi for neri is a wild species and there are not enough successors to the experts with knowledge on locating noriutsugi and removing its bark. If the low amounts of noriutsugi available does not change, this will permanently impair washi-making for the restoration of cultural property. For example, uda washi paper used for soura-kami (the final lining paper) of hanging scrolls is made using neri extracted from noriutsugi. Therefore, we are concerned that restoring hanging scrolls will become difficult in the near future.
Commissioned by the Agency for Cultural Affairs, the Center for Conservation Science has been conducting a research project: “Investigation of Tools and Materials Used for the Preservation and Restoration of Fine Arts and Crafts” with the Department of Art Research, Archives and Information Systems and the Department of Intangible Cultural Heritage. As an important investigation of this project, we are working for sustainable and stable supply of noriutsugi. This investigation is conducted in cooperation with Hokkaido Prefecture, Shibetsu Town and others. We visit the noriutsugi growing area in Shibetsu Town and hold regular discussion meetings. We will provide supports for sustainable and stable supply of noriutsugi and conduct scientific studies on why neri extracted from noriutsugi shows such excellent characteristics.
