Outline of Final Research Achievements

The advantage of radiocarbon dating is that we can measure wood of any tree species. We investigated the age of building by the radiocarbon dating method when the old building was built, and improved the chronology judgment method. The national treasure Komyoji Temple's Nio-mon was confirmed the building age and the subsequent repair process was clarified. It is revealed that Kanden-an important cultural property is rebuilding after the fire, and the bath shop remains as it is built by Matsudaira Humai-ko. World Heritage Shirakawago · Gokayama's Gassho-dukuri-houses made it clear that many used old timber from 16-17century, became a large roof currently seen in Genroku era. Besides this, We got good results from age surveys of numerous cultural property buildings such as the many old private houses , the town houses in Kyoto, the private houses in the Tone River basin.
