Togyū Okumura (奥村 土牛, Okumura Togyū; 18 February 1889 – 25 September 1990) was a famous Japanese modern painter of the Nihonga style of watercolour painting. His original name was Yoshizō (義三). The name Togyū referred to a poem from his father, who ran a publishing business. Okumura is characterized by his works, which achieve an unusual, exquisite quality of colours through the application of the white gofun pigment 100 or 200 times as a foundation.
