Yoshimune Arai was born in 1873. He ded in 1945. He is known for several woodblock prints in shin hanga style, among them the famous night-scenes series published by Hasegawa/Nishinomiya. Yoshimune may primarily have worked as a painter, and the well-known prints may have been created by professional carvers and printers in collaboration with the artist. But we really do not know.
Practically nothing is known about Japanese artist Yoshimune Arai. His name became known after the death of art dealer and collector Robert O. Muller in 2003 when his huge collection of shin hanga came into the market for the first time.
Beautiful works. I hope you like them as well as I do.
