Practical work on surface cleaning
“Workshop on Conservation and Restoration of Urushi Objects” was held at Museum für Ostasiatische Kunst, Museen Köln (Museum of East Asian Art, Cologne), Germany, from December 2nd to 6th, 2019. Tokyo National Research Institute for Cultural Properties (TNRICP) has conducted the annual workshops with the cooperation of the Museum since 2007. The aim of the workshops is to facilitate the preservation and utilization of urushi objects in museum collections outside Japan. This year’s workshop focuses on the fundamental knowledge and techniques required for storing, maintaining and handling urushi objects, and six conservators from Western countries participated.
The topics of lecture included the chemical properties of urushi, the multi-layered structure of urushi objects and typical decoration techniques, degradation and damage, and appropriate storage environments. The practical work on applying urushi to wooden substrates helped the participants understand the characteristics of urushi. In addition, the case studies on the conservation and restoration of urushi objects in Japan were introduced, and Japanese conservation ethics and techniques were shared. The participants also experienced applying remedial treatment to urushi objects, such as temporary stabilization of damaged areas and surface cleaning. In the question-and-answer session on the last day, the deterioration and damage of urushi-coated surfaces and their treatments were actively discussed.
We hope that introducing basic knowledge about urushi objects as well as materials and techniques used for their conservation to the conservation specialists overseas will contribute to the safer preservation and the further utilization of urushi objects overseas.

Advanced workshop: practical work on documentation
Two workshops on the conservation of Japanese textiles were held at the Research Center for Conservation of Cultural Relics in National Taiwan Normal University (NTNU), Taipei, from August 14th to 23rd, 2019. A basic workshop, “Cultural Properties of Textiles in Japan,” was conducted from August 14th to 16th, and an advanced workshop, “Conservation of Japanese Textiles,” was run from August 19th to 23rd. These workshops have been co-organized annually since 2017 by Tokyo National Research Institute for Cultural Properties and NTNU for the preservation and utilization of Japanese textiles overseas, as part of our joint research. The lectures and instructions were presented by researchers specialized in textiles and conservators from Japan and Taiwan. Conservators, curators and students from around the world participated in the workshop; there were 11 participants from 10 countries in the basic workshop and 6 participants from 5 countries in the advanced workshop.
The basic workshop included lectures on the systems for the protection of tangible and intangible cultural properties, textile and clothing materials, and representative textiles in Japan. The participants also experienced folding and displaying Japanese garments (kimono). In addition, the practical work on making a paper model of kimono helped the participants to understand the construction of kimono. The advanced workshop comprised lectures and practical work on topics such as the degradation of textiles, scientific analysis of dyes, and cleaning of textiles. Furthermore, the participants experienced stitching a support silk fabric to the back of an old textile fragment and making a Japanese traditional folder for it. This served as an opportunity for the participants to comprehend Japanese approaches to textile conservation. In both workshops, case studies on display and conservation of Japanese textiles were shared, and opinions regarding conservation approaches, materials and methods were actively exchanged.
It is expected that introducing fundamental knowledge about Japanese textiles and their conservation to conservation specialists overseas could contribute to the better conservation and utilization of Japanese textile objects outside Japan.
Practical work on applying urushi
The Workshop on Conservation and Restoration of Urushi Objects was held at Museum für Ostasiatische Kunst, Museen Köln (Museum of East Asian Art, Cologne), Germany, from November 26th to 30th, 2018. Tokyo National Research Institute for Cultural Properties (TNRICP) has conducted the annual workshops with the cooperation of the Museum since 2007. The aim of the workshop is to preserve and utilize urushi objects (lacquerware) in museum collections outside Japan. This year’s workshop was the basic course focusing on the knowledge and techniques required for storing, maintaining and handling the urushi objects, and six conservators attended from several countries around the world.
The lectures included the chemical structure and properties of urushi, the structure and decorations of urushi objects, the typical damages and degradation, and the appropriate storage environment. Case studies on conservation and restoration of urushi objects in Japan were also introduced, and principles of restoration and processes of applied treatments were explained. The practical work on applying urushi to the wooden spoons helped the participants to understand the characteristics of urushi more clearly. Furthermore, the participants experienced the remedial treatment of an urushi object such as stabilizing the damaged areas and cleaning the surface. The ways of selecting and making of tools used in conservation were also explained. On the last day of the workshop, various topics, for example, the differences on conservation ethics and principles between the East and the West and the possible application of knowledge and techniques acquired in this workshop were discussed.
It is hoped that introducing the fundamental knowledge and Japanese conservation techniques of urushi objects to the conservation specialists overseas will contribute to the safer preservation and utilization of the urushi objects overseas.
Practical session
The International Course on Conservation of Japanese Paper was run from August 27th to September 14th, 2018. This course has been jointly organized by Tokyo National Research Institute for Cultural Properties (TNRICP) and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM) since 1992. It is aimed at contributing 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. This year, 10 specialists in conservation from 10 countries (Argentina, Australia, Bhutan, Canada, Denmark, Fiji, France, Poland, the UK and Zambia) were selected as participants among 80 applications from 38 countries.
The course was composed of lectures, practical sessions and an excursion. The lectures covered protection systems of both tangible and intangible cultural property in Japan, basic insights into Japanese paper, traditional conservation materials and tools. The practical sessions were led by instructors from a certified group holding the Selected Conservation Techniques on “Restoration techniques for mounts.” The participants gained experience of restoration work of paper cultural property from cleaning it to mounting it in a handscroll. Japanese-style bookbinding and handling of folding screens and hanging scrolls were also included in the sessions. The excursion to the cities of Nagoya, Mino and Kyoto, arranged in the middle of the course, offered an opportunity to see folding screens and sliding doors in historic buildings, the Japanese papermaking which is designated as an Important Intangible Cultural Property of Japan (Honminoshi), a traditional restoration studio, and so forth. On the last day, the conservation materials for paper cultural properties and approach to the selection of appropriate materials for paper conservation were discussed.
The participants could gain a deeper understanding of not only conservation materials and tools used in Japan but also conservation approaches and techniques using Japanese paper throughout this course. We hope that the knowledge and techniques they acquired in the course will be applied to conservation and restoration of cultural property overseas.
Basic workshop: lecture on Japanese textiles
Advanced workshop: practical work to understand the characteristics of dyes
Two workshops on the conservation of Japanese textiles were jointly organized by Tokyo National Research Institute for Cultural Properties (TNRICP) and National Taiwan Normal University (NTNU) for the purpose of preservation and utilization of Japanese textiles overseas. A basic workshop “Cultural Properties of Textile in Japan” was held from August 8th to 10th and an advanced workshop “Conservation of Japanese Textile” was held from August 13th to 17th, 2018. Both were conducted at the Research Center for Conservation of Cultural Relics in NTNU by researchers specialized in textiles and conservators from Japan and Taiwan. The participants were conservators, researchers and students; the basic course had nine participants from six countries and the advanced one had six participants from five countries.
The basic workshop started with lectures on the systems of protection of tangible and intangible cultural properties, and moved its focus to fibers and threads as textile materials and some of the representative textiles in Japan. Following the lectures, the participants also experienced folding and displaying Japanese garments (kimono). The practical work on making a paper model of kimono helped the participants to understand the general way in which kimono is constructed from a bolt of fabric. The first half of the advanced workshop focused on the identification of dyes, surface cleaning and wet cleaning. The latter half introduced a Japanese approach to textile conservation and treatment, and the participants experienced stitching a support silk fabric to the back side of an old textile fragment and making an enclosure for it. In both workshops, there were lectures on case studies, and various methods of the display and conservation of Japanese textiles were shared. It served as an opportunity to comprehend conservation materials and application methods as well as textile materials and techniques.
Similar projects will continue to be implemented with the aim of contributing to not only the conservation and utilization of Japanese tangible textile objects abroad, but also the preservation of related intangible cultural properties.

Workshops on Conservation of Japanese Lacquerware (urushi objects) have been held since 2006, with the cooperation of Museum für Ostasiatische Kunst, Museen Köln (Museum of East Asian Art, Cologne), Germany. The workshops introduce the knowledge and techniques required for the preservation and utilization of lacquerware overseas. In these past 10 years, 179 professionals and students in total had participated from 17 countries. In order to measure the outcomes of the past workshops, this year, an evaluation seminar was held at Tokyo National Research Institute for Cultural Properties (TNRICP) on November 8th and 9th, 2017.
Prior to holding the seminar, a questionnaire survey targeting all former participants was conducted. Contributors to the seminar were gathered from the respondents of the questionnaire, and 4 specialists and professors in conservation and restoration were invited from 4 countries (Belgium, Germany, Greece and the USA). On the first day of the seminar, the contributors presented their conservation projects and/or educational activities in conservation, which were undertaken after they participated in the workshops. The presentations provided the opportunity to share their situations and challenges on how the acquired knowledge and skills were applied to their work. The second day started with reporting the results of the questionnaire survey from TNRICP, followed by an in-depth discussion with the contributors. Issues on conservation of lacquerwares overseas and how we can support to address such issues by providing the workshops were considered.
