The Kawasoe family were craftsmen specializing in figurines and glaze research, passing down their skills for generations. In 1963, Tameo, grandfather of the current owner, founded Kosen Kiln and spent over a decade perfecting Nabeshima celadon glazes, despite the risk of financial ruin. Today, third-generation owner Takahiko Kawasoe preserves this tradition in Okawachiyama, the “hidden kiln village.” After 56 years, he has resumed celadon R&D, blending classic techniques with a fresh perspective.
