, originally , was an Edo period Japanese potter, painter, and calligrapher. He was also known by the pseudonyms Shisui, Shà Âkosai, Shuseidà Â, Tà Âin, and Shinshà Â. He is associated with Kyà  ware and Kiyomizu ware.
Ogata Kenzan was the third son born into a rich kimono merchant family in Kyoto. The family's shop, the Kariganeya, was patronized by Oeyo, the wife of Tokugawa Hidetada, and Tokugawa Masako. His father was Ogata Sà Âken (1621âÂÂ1687), a calligrapher and patron of Noh. His older brother was the painter Ogata Kà Ârin (1658âÂÂ1716). Following his father's death, the eldest of the Ogata brothers took over the Kariganeya, allowing Kenzan and Kà Ârin to enjoy their inheritance and pursue pottery and painting. From a young age, Ogata received lessons in pottery from Koho and Rakuichi, grandchildren of Hon'ami Kà Âetsu.
In 1689, Ogata established Shuseidà  hall south of Ninna-ji. Ogata studied with the potter Nonomura Ninsei whose Omuru kiln was located at the front gate of Ninna-ji. In 1699, Kugyà  Nijà  Tsunahira provided Ogata with a mountain villa in Ukyà Â-ku, Kyoto where Kenzan established his own kiln. In 1731, Kenzan was invited by Cloistered Imperial Prince Rinnojinomiya Kinkan to move to Edo where he spent the remainder of his life. He died at the age of 81.
Ogata produced a distinctive style of freely brushed grasses, blossoms, and birds as decorative motifs for pottery. His pieces were noted for their perfect relation between design and shape. He often collaborated on the decoration of pottery with his older brother, Ogata KÃ Ârin, after whom the style known as Rinpa was named.
