About the artist
Doitsu Sekai was 19th-century Rinpa painter and the fourth generation head of the Uge-an, the painting studio established by Hoitsu Sakai (1761-1828). The son of Sodo Yamamoto, Doitsu studied under both the Korin-style painter Hoitsu Sakai and his student Shin'ichi Nozaki (1821-1899). He took the Sakai name when he was adopted by Ohitsu Sakai. Doitsu is also known as Doitsu Uge. During the Meiji period, woodblock prints were printed after of Doitsu's paintings.
