Scene of discussion at the seminar
Since 2018, the Japan Center for International Cooperation in Conservation has been hosting the World Heritage Seminar Series, which aims to transmit information and facilitate exchange of opinions about the world heritage system and its trends domestically. In FY 2023, titled as “The Increasing Complexity of the Eyes Watching over World Heritage – Operational Guidelines, Preliminary Assessments, and Impact Assessments -,” the seminar focused on the evaluation methods and system operation of world heritage, especially on the guidance of the Heritage Impact Assessment (HIA), compiled recently by UNESCO and others. The meeting was held in-person on December 21, 2023, at the Tokyo National Research Institute for Cultural Properties (TOBUNKEN), in which 90 persons participated, mainly representatives from local governments all over the country.
After an introductory explanation of the purpose of the seminar was provided by Mr. KANAI Ken, Head of the Resource and Systems Research Section of the Japan Center for International Cooperation in Conservation, Mr. SUZUKI Chihei of the Agency for Cultural Affairs reported on the discussions held and decisions made at the latest World Heritage Committee meeting under the title of Trends on World Heritage. Then, Ms. FUTAGAMI Yoko, Head of the Cultural Properties Information Section of the Department of Art Research, Archives and Information Systems, made a presentation titled Recent revisions of the Operational Guidelines and their background – To ensure dialogue and reliability –. Subsequently, Mr. SUZUKI , on behalf of Mr. NISHI Kazuhiko (Agency for Cultural Affairs) made a presentation on the contents and points to note of “Guidance and Toolkit for Impact Assessment in a World Heritage Context.” Finally, Mr. NAKASAWA Hiromasa (Special Historic Site – Sannai Maruyama Jomon Culture Center, Aomori Pref.) presented on the significance and assignments of HIA, based on specific case studies, with the title of “Protection and Heritage Impact Assessment of Jomon Prehistoric Sites in Northern Japan.” Thereafter, all speakers discussed the evolving value of World Heritage Sites, impact assessments made on them, and future challenges.
Through the reports, presentations, and discussions, we reaffirmed the necessity to involve a wide range of stakeholders and incorporate relevant regulatory systems for implementing the HIA guidance. Furthermore, we learned that, in recent years, some countries have begun to regard buffer zones and their surrounding areas as areas for integrated development based on the cultural heritage values of the site, although they have traditionally been considered as a “shield” for assets. With these topics included, the Center will continue to study the international heritage protection system.
Trainees learning photogrammetry and 3D modelling
Trainees learning photogrammetry and 3D modelling
The Japan Center for International Cooperation in Conservation held a workshop for four days, from December 24 to 27, 2023, which focused on technology transfer of the 3D digital documentation for cultural heritage and case studies, and discussion on its subsequent application for professional staff involved with cultural heritage in the Kingdom of Bahrain. The Bahrain Authority for Culture and Antiquities has been promoting the introduction of 3D digital documentation as one of the solutions to improve issues regarding documentation, preservation, and utilization of cultural heritage. As a training program for these issues was requested, this workshop was conducted as Activities for Exchanges in International Cooperation for Conservation of Cultural Heritage in fiscal year 2023, granted by the Agency for Cultural Affairs.
Fifteen trainees from different specialties, including museology, conservation science, conservation and restoration, archaeology, and architecture, attended the workshop. Two of them participated from the neighboring Gulf countries of UAE and Kuwait. Together with lectures on various ways to create 3D digital documentation, trainees tackled the practical task of making a 3D model from the beginning, solely by themselves, applying photogrammetry to one exhibit object selected from the museum. By experiencing trial and error on their own, trainees acquired the skills and knowledge to create the 3D model and consider their subsequent use. At the discussion on the last day, the ideas of each trainee as to how to make the best use of 3D digital data and models were actively discussed, such as for improving satisfaction with the descriptions of museum exhibits, and utilization in recording of the conservation process for application to the digital museum or for domestic and international promotion.
Despite the rich cultural heritage preserved not only in Bahrain but in other Gulf countries, the lack of human capacity to preserve and utilize cultural heritage is concerning, but it is hoped that some of these issues will improve through learning ways to perform documentation efficiently using 3D digital techniques.
Survey scene at an old house
A vernacular house in which rammed earth and stone masonry structures coexist.
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), 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.
Following the previous survey conducted in the eastern region from April to May 2023, the second field survey mission of this year was implemented from October 29 to November 4. Four staff members of TOBUNKEN, one from Nara National Research Institute for Cultural Properties (NABUNKEN), and two external experts were dispatched, and the team was joined by two staff members from DCDD. We jointly carried out a field survey in the two provinces of the central region, namely Bumthang and Wangdue Phodrang.
Most of the target houses had been identified in our preparative survey conducted in 2022. Eleven houses in total, including those newly found, were investigated this time in a detailed manner that included taking measurements and interviewing the residents. Two houses among them were rammed earth houses commonly seen in the western area of the country, and six were stone masonry houses widely located in the eastern area, while both construction techniques were combined in the other three houses. Especially in the eastern part of Wangdue Phodrang province, a tendency had been observed that the rammed earth technique was exclusively used further in the past, and stone masonry has gradually become dominant over time. However, our analysis of the transitional history of each house suggests that things were not so simple, and present more complex pictures.
On the other hand, although we had been focusing on such aspects as building type, construction technique, and transitional history of the houses, this time during the interviews we started to pay more attention to ethnographic factors such as oral traditions about houses and how each room is used. By adding information about villager’s lifestyles, which reflected on the transition and locality of the housing type, into our consideration, hopefully diverse values of the Bhutanese traditional houses as cultural heritage will become clarified.
The survey was implemented with the financial support of a JSPS Grant-in-aid for Scientific Research (B), “Vernacular stone masonry houses of Bhutan: study on the architectural characteristics and the suitable approach for protection as cultural heritage” with TOMODA Masahiko as the principal researcher.
Excavation of the Terrace on the West Embankment of the East Baray
The newly installed (left) and the existing (right) supports at hazardous spots inside the East Tower of the Central Complex
Ta Nei Temple is located facing the East Baray, one of the huge reservoirs that used to supply water for the Angkor capital. The terrace at the eastern end of Ta Nei Temple was built on top of the West Embankment of the East Baray, being not only significant as the main entrance of the temple, but also connected to the other temples through the Embankment. However, due to the extremely poor condition of the terrace, its construction period and structural features have remained uncertain.
The Tokyo National Research Institute for Cultural Properties has so far conducted excavation of the terrace in three periods: November 2017, March 2018, and August to October 2018, aiming to delineate the plan of the terrace and consider the intention of construction. These previous surveys revealed plans of the terrace, especially the structure of the west wing. In this term, four staff members were dispatched from November 5 to 30, 2023 to carry out archaeological and architectural studies to understand the northern and the southern sections of the terrace as well as the construction process, in cooperation with Authority for the Protection and Management of Angkor and the Region of Siem Reap (APSARA).
Although traces of the stone masonry structure at the northern and southern sections of the terrace were scarcely identified, the excavation provided some clues to enable estimation of the original construction process of the terrace based on stratigraphical analysis of the mound structure. Additionally, a structure made of stones and bricks, which appears to be the foundation of a wooden pillar, was discovered on the surface of the terrace. Those remains indicate that a wooden structure was presumably built on the terrace at a certain time of its history. A level directly below where many roof tile fragments were unearthed by this excavation is thought to be the ground surface at the time when the wooden structure was built on the terrace. The details of the structure of the terrace still have not been ascertained, requiring further investigation.
In addition to the above-described investigation of the terrace, we conducted minor repair work on the East Gate that had been completed last year, and continued its documentation. Moreover, we installed additional supports at hazardous spots inside the East Tower of the Central Complex, and held on-site meetings to discuss future collaborative activities at the temple.
Remarks of His Majesty Preah Bat Samdech Preah Boromneath Norodom Sihamoni, King of Cambodia
Reporting on the conservation and sustainable development project of Ta Nei Temple
On November 15, 2023 Ms. KUROIWA Chihiro, Associate Fellow of the Japan Center for International Cooperation in Conservation, attended the “4th Intergovernmental Conference for the Safeguarding and the Development of Angkor” held at UNESCO Headquarters in Paris, France.
In 1992 following the end of the Cambodian Civil War, Angkor Monuments were inscribed on the World Heritage List, but at the same time, they were also placed on the List of World Heritage in Danger. At the first intergovernmental conference held in Tokyo in 1993, co-chaired by Japan and France and attended by 30 countries and 7 international organizations, the “Tokyo Declaration” was adopted calling for international cooperation towards safeguarding the monuments and sustainable development of the surrounding area. In the same year, the International Coordinating Committee for the Safeguarding and Development of the Historic Sites of Angkor (ICC-Angkor) was established to formulate technical guidelines and evaluate the activities of international conservation teams.
The Intergovernmental Conference takes place every 10 years to review and evaluate the ICC-Angkor and to discuss the policies for future conservation and sustainable development. The second conference was held in 2003 (France), the third in 2013 (Cambodia), and the fourth was held this time in Paris. In the past 30 years, numerous international projects for restoration and conservation have been implemented at the Angkor Monuments and Sambor Prei Kuk, another World Heritage Site.
His Majesty Preah Bat Samdech Preah Boromneath Norodom Sihamoni, King of Cambodia, H.E. Ms. Audrey Azoulay, Director General of UNESCO, H.E. Ms. Rima Abdul-Malak, Minister of Culture of the French Republic, Mr. KOMURA Masahiro, Parliamentary Vice-Minister for Foreign Affairs of Japan, and other international members attended the conference. During the technical session, presentations were made by teams from various countries involved in the conservation of Angkor and Sambor Prei Kuk monuments. We also reported on the collaboration with APSARA for the conservation and sustainable development of Ta Nei Temple.
The workshop
3D documentation using Agisoft Metashape and iPhone Scaniverse has been rapidly introduced recently. The introduction of this technology can not only reduce the working time, but also make it possible to document cultural heritage with very high precision.
Following a beginner course held in July, the Japan Center for International Cooperation in Conservation arranged an intermediate/advanced course on 3D digital documentation for experts who are working abroad, held on November 26 2023. Dr. NOGUCHI Atsushi from Komatsu University was invited as the lecturer. The main aim of this workshop was for the Japanese experts to learn 3D documentation and then to spread their knowledge among foreign experts.
In total, 18 specialists with a variety of backgrounds such as archaeology, conservation science, and conservation architecture joined this workshop and studied how to make orthographic projections, cross-sections, contour maps, and tiered color maps from 3D models using Cloud Compare.
Cleaning of adhering materials
Treatment of detached finish layers
The Tokyo National Research Institute for Cultural Properties has been conducting research and surveys investigating stucco decorations since fiscal year 2021 as part of the “International Research on Technology for the Conservation and Restoration of Cultural Heritage” program.
From October 25 to November 16, 2023, a research survey on the conservation and restoration of trowel paintings on doors and under eaves of the earthen storehouse of the former Kina-Saffron-Shu-Honpo in Nagaoka City, Niigata Prefecture was conducted. This work was carried out as part of the “Conservation and restoration research of trowel paintings in the earthen storehouse of the former Kina-Saffron-Shu-Honpo” commissioned by Nagaoka City, with the aim of establishing conservation and restoration methods for trowel paintings in Japan from the perspective of cultural property conservation studies.
In recent years, the value of trowel painting in Japan as a cultural asset has been increasing, and the importance of an intervention method called “conservation and restoration” that can be advanced with clear evidence that it is compatible with existing materials is therefore also increasing. In this research study, conservation and restoration experts on stucco decoration were invited from Europe to discuss how to deal with the various types of damage found on trowel paintings. As a result, we were able to establish appropriate conservation and restoration methods for the removal of dust and other adherents and for damaged areas such as peeling and flaking, and achieved a certain level of success.
In the future, the state of the wall paintings after conservation and restoration will be monitored, and methods for reinforcing the plaster, which has deteriorated over time, will be studied further.

The Japan Center for International Cooperation in Conservation (JCICC) is currently undertaking a research project overseas, specifically concentrating on innovative approaches to conserving modern architectural heritage. This project is part of the “Overseas Case Study on the Protection and Transmission of Contemporary Architecture,” commissioned by the Agency for Cultural Affairs. After conducting a field survey in Taiwan in September, we extended our research to include field surveys in France, Italy, and Denmark from October 3 to 13.
Over the past three decades in Europe, the recognition of modern and contemporary architecture as a valuable social asset has gained widespread acceptance. This was notably encouraged by the Council of Europe in 1991, which recommended that member countries adopt specific strategies to safeguard 20th-century architecture. Furthermore, the guideline on “architectural culture (baukultur)” for social development was emphasized during the meeting of European ministers responsible for culture at the 2018 World Economic Forum in Davos. Amidst these social trends, in 2017 a new law was implemented in France called the “Law on Freedom of Creation, Architecture and Heritage” (LCAP Law). This legislation incorporates the “Remarkable Contemporary Architecture” (ACR) labeling system, designed to promote the conservation and appreciation of modern architecture. In Italy, the Directorate General for Contemporary Art and Contemporary Architecture within the Ministry of Cultural Property and Cultural Activity (which is now the Directorate General for Contemporary Creativity within the Ministry of Culture) was established in 2001. Since its inception, the Directorate has consistently undertaken surveys aimed at identifying contemporary architecture with significant artistic value across the entire territory. In Denmark, while there are no specific administrative initiatives dedicated to conserving modern architectural heritage, a private philanthropic organization called “Realdania” has taken on this responsibility. Established in 2000 as an extension of a real estate financing business, Realdania is actively pursuing initiatives to safeguard Danish architectural heritage through investments. Their efforts also focus on the preservation and development of modern Nordic design masterpieces created by Danish architects.
During this survey, we conducted visits to the French Ministry of Culture, the Italian Ministry of Culture, and Realdania, engaging in interviews to gain insights into their activities, challenges, and outlook regarding the conservation of modern architecture. The purpose was also to verify the status of the targeted modern architecture on-site. While significant efforts have been made to conserve modern architecture, it remains challenging to assert that modern architecture has fully garnered recognition and status as cultural heritage in each country. It was confirmed that these organizations are seeking new forms of conservation suitable for modern architecture through continuous dialogues with diverse stakeholders and the implementation of experimental trials of conservation and sustainable development.
The results of this survey, along with the results from our field survey in Taiwan and a bibliographic study into the relevant legal systems in each country or region, will be consolidated into a final survey report in November 2023. This report will be open to public via the Institute’s online repository.
Visit to Ichijodani Archaeological Site, Fukui Prefecture
The Tokyo National Research Institute for Cultural Properties has been involved with cooperative projects to preserve the cultural heritage in Bahrain for many years. Recently, Dr. Salman Almahari, Director of Antiquities and Museums in Bahrain, and colleagues requested to study the utilization of AR, VR, and digital contents in Japanese museums and archaeological sites, because they plan to introduce them in Bahraini museums and historical sites. Therefore, Dr. Salman Almahari and Dr. Melanie Muenzner, who is in charge of the UNESCO World Heritage Inscription in Bahrain, were invited to Japan from October 10 to 15, 2023 and a study tour was arranged.
During their stay in Japan, Japanese specialists delivered lectures on several topics, including basics of 3D documentation of cultural heritage, the utilization of AR for tourism promotion in Japan, among others. The Bahraini specialists also visited the Tokyo National Museum, Ichijodani Archaeological Site, Nara National Research Institute for Cultural Properties, NHK and NHK Enterprises to study the latest examples of AR, VR, and digital contents such as ultra-high definition 3DCG.
The study tour was funded by the Agency for Cultural Affairs, Japan. As a part of the same project, we also plan to organize a workshop, “3D Digital Documentation of Cultural Heritage and Its Applications,” for Bahraini experts to take place in December 2023.
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.

Songshan Creative Park: Creating a space for a rental artwork/performance studio that captures the ambiance of a historic tobacco manufacturing factory (municipal designated historical sites).
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.”

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.

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.
