Contemporary folk craft cups with an amazing subtle metallic gloss & unique “Tobikanna“ details.

The black metallic finish of our Koishiwara-yaki cup is achieved through a unique glaze developed by our Koishiwara Artisan. He mixes iron powder to the rice straw ash that he uses as the glaze.

The distinct pattern on our cups is done with a technique called “Tobikanna.” The artisan uses a metal tool to apply chatter markings on the half-dry surface of the cup, while it is turning on the potter’s wheel. True to its name the “jumping iron” leaves the typical Koishiwara-Yaki markings behind.

The artisan Yusuke Kumagae crafts the Asemi Co. Koishiwara-yaki cups in Koishiwara, Fukuoka Prefecture.
