Tea cup by Kimura Seiketsu of Mashiko, with three elements of circle, triangle, square. Kimura, born in 1953, has been operating an independent kiln in Mashiko since 1983. The town of Mashiko, in Tochigi Prefecture, is one of the world's largest pottery communities. Starting as a production center for utilitarian pottery in 1858, Mashiko today is a mecca for the ceramic artist-craftsperson largely due to the town's exposure by the late Hamada Shoji and other members of the Mingei (Folk Craft) Movement. Reportedly, there are currently over 400 kilns in operation here.
