Debriefing Session on the Conservation Environment of Usuki Stone Buddha Statues
Since 2000, the National Research Institute for Cultural Properties, Tokyo has been promoting a joint research study with Usuki City to establish the conservation plan of the Usuki Stone Buddha Statues, a national treasure and a designated historic site for the next term. On November 6th, we held report presentations on the results of research for these 10 years in the Debriefing Session on the Conservation Environment of Usuki Stone Buddha Statues at the central community hall of Usuki City.
Mr. Takeo Oku at the Agency for Cultural Affairs first made a speech on the significance of the conservation plan for the next term, followed by Mr. Shoichi Shimoyama at Kyushu University presenting a lecture on the Aso ignimbrite, on which the Usuki Stone Buddha Statues were sculpted. Then Mr. Lee Chan-hee at the Kongju National University and Mr. Kim Sa-dug at the National Research Institute for Cultural Properties in South Korea gave lectures about the survey on the deterioration states of stone cultural properties in South Korea and the conservation of them. Following these lectures, the researcher of our Institute made a report on the results of research, including the outline of research, the deterioration state of the surface of rock-carved Buddha statues, and the water and air environments. By reviewing the results of the survey on the causes of deterioration, the researcher also made some proposals about measures against deterioration, such as antifreeze measures during cold periods and measures for inquiline control, as well as deterioration monitoring techniques. Closing the session, the Usuki City Education Board presented draft plans about a conservation project for the next term and subsequent monitoring and maintenance, with a title called the Vision of Long-Span Conservation Plan for Usuki Stone Buddha Statues. They asked the participants for their understanding.
Although our research continued for an unprecedented 10 years for one cultural property, we have gained a lot of results here. We hope that these results will be utilized to conserve not only the Usuki Stone Buddha Statues, but many other stone cultural properties as well.
