Osumi Jo Fujiwara Masahiro was from Obi, Miyazaki pref. He is said to have been a nephew of Kunihiro or merely a pupil. The number of his production is very small and his style is quite similar to Kunihiro, so It is said that he may have been working on Kunihiro’s behalf. This work is a rare masterpiece that we definitely recommend to you.
