member of a Japanese family of professional artists who specialized in Buddhist paintings (butsuga), creating a new style of religious painting that incorporated features of Chinese Southern Sung art.

A high-ranking priest of the Shingon sect of Buddhism, Shōga painted butsuga for the Tō and Jingō (or Takaosan) temples with which he was associated in Kyōto, as well as for individual court noblemen who used his paintings in their private religious observances. Of his butsuga, the most important was a group of the “Twelve Gods,” painted on screens, in 1191, for the Tō Temple. The painting of the Moon deity, the only one of the 12 that is extant, exemplifies the style of iconography introduced by Shōga and continued by the Takuma family. It contrasts with earlier painting in its pale colours and limited patterns, and it reflects the Southern Sung influence most directly in the emphasis on brushwork. The deity, moreover, is now represented as a standing figure and in profile—a posture that displays to good advantage the graceful flowing lines of the robes.
