Insho Domoto (1891–1975) was a Japanese-style painter born in Kyoto. He was born into a family engaged in sake brewing and entered the Kyoto Municipal Special School of Painting in 1918. While still a student, he joined the Seikosha painting academy of Suisho Nishiyama in 1920.
In 1919, Domoto made his debut at the first Teiten exhibition with Fukakusa. In 1921, he received the Special Award for Chokyuzu, followed by the Imperial Art Academy Award for Kegon in 1925, establishing his position in the Japanese art world. In 1933, he founded and led the Toko-sha painting academy, and later served as a professor at the Kyoto Municipal Special School of Painting and as a judge for the Teiten.
He was appointed an Imperial Household Artist in 1944 and became a member of the Japan Art Academy in 1950. In 1961, he was awarded the Order of Culture. In 1966, he opened the Domoto Museum of Art, which he designed himself. He died in 1975. The present Kyoto Prefectural Insho-Domoto Museum of Fine Arts traces its origins to this museum.
