Japanese painter best remembered as a suiboku-ga (“water-ink painting”) artist. He worked in the manner of the 15th-century artist Sesshū at a time when the orthodox style of the Kanō school dominated painting.

Initially a student under a Kanō artist (probably Shōei), he became familiar with the style of Sesshū while a painter to the Mōri family in Suō province (now Yamaguchi prefecture). The Mōris owned the most famous of Sesshū's works: a 55-foot- (17-metre-) long landscape painting from 1486. He copied this scroll painting, modeled his own style after it, and used it to back his claim in the famous legal contest with Hasegawa Tōhaku over succession to the line of Sesshū. The case was won by Tōgan, who gained the right to call himself the “fifth generation of Sesshū.” One of his Sesshū-style paintings, “Chinese Landscapes,” is an ink landscape closely resembling the original Sesshū scroll, but it lacks the bold lines of the Sesshū landscape and has, instead, more variations in tones, creating a greater sense of atmospheric depth. A screen painting of Mount Yoshino, famous for its cherry blossoms, and “The Deer” are among Tōgan's well-known works. Most of his work is in the Daitoku Temple in Kyōto.
