Tosa Mitsusada or Fujiwara no Mitsusada was the second son of Tosa Mitsuyoshi (1700-1772), younger brother of Mitsuatsu. In 1754, he became an Edokoro azukari (a term used during the pre-Meiji period for a high ranking artist working for the Imperial Court). In the 1760's he was commissioned to paint fusuma for the court and in 1789, when the Kyoto Imperial Palace was being renovated, he was requested to paint fusuma. He left a number of admirable copies of ancient Chinese paintings and was a staunch exponent of Tosa tradition, even creating a temporary revival of the Tosa School
