Obayashi ware is pottery made in Obayashi, Tatsue, Iida City, Nagano Prefecture. It is said that Shinoda Tokusai established an official kiln for the Iida Domain. Obayashi ware is the oldest pottery in Nagano Prefecture. Their kiln is known for following the Mino style. The iron-glazed komainu statuettes that were made in 1609 have been handed down over generations.
Around 1897, Hagimoto Tosai applied the technique of carving seals into the pottery to make Tenryu ware.
They closed temporarily, but in the late Edo period, Mizuno Gizaburo moved to Obayashi and restored the kiln. Before that, Mizuno Gizaburo used to teach the methods of Fuetsu ware, which was an oniwa ware of the Iida Domain.
