From June 15 to 20, Director General Suzuki, Deputy Director General Nakano, Mr. Takayanagi of the Department of Management and Mr. Katsuki of the Department of Research Programming visited the ruins in the Xinjiang area of China. Xinjiang is located in the northwest part of China, and most of the area is desert. In ancient times, various oasis city states flourished in this area; the many ruins we visited on this trip were built in that period. We toured Jiaohegucheng, the Bezeklik stone caves, the Astana ancient tombs, and Gaochang in Turfan; the Subash Buddhist remains, the Kumutula stone caves, and the Kyzyl stone caves in Kuqa; and the Museum of Xinjiang Uighur Autonomous Region in Urumqi. We had opportunities in each region to meet some of the people who worked on conserving cultural heritage. Although it was a short trip, it was significant in our learning about conservation of the ruins in the Xinjiang area.
