Founded in 1922 at HIgashiyama Senyū-ji Temple, Touan has since become one of the largest Kyo-yaki and Kiyomizu-yaki producers, with over 20 artisans hand-crafting and painting each piece. In contrast to the standard overglaze painting technique that Kyoto ceramics are known for, Touan has developed an underglaze technique that produces the same vibrant colours and delicate lines, but is more durable due to the glaze being layered on top of the painting.
Touan is headed by fourth generation potter Dobuchi Yoshiaki (土渕善亜貴) who is known for his stunning developments in glazing, creating Touan's new signature crystal flower glaze. Additionally, he is one of only a handful of potters who has successfully replicated the elusive yōhen tenmoku glaze.
