Ōshima Joun

His studio, Sanseisha — run with his brother Ōshima Yasutaro, also a skilled artist — was very successful and at one point employed 11 assistants.

"[3] Old labels on Joun's tomobako (wooden storage boxes) suggest that the well-established Ginza (in Tokyo) purveyor of silver and other fine metal wares Miyamoto-Shoko (established 1880) may also have handled some of Joun's sales.

[4] Many of Joun's students (Ryūki, Chōkichi Suzuki (see mention in Victoria and Albert Museum), Sessei Okazaki, Kumazō Hasegawa, Gorosaburō Kanaya, Eisuke Jomi) went on to achieve distinction of their own.

[7] Ōshima Joun used the gō or art-name 一乗軒 (Ichijoken) and that inscription can be found on many of his inscribed boxes.

Additionally, a small group of bronzes (which appear to be made for export) have been identified that are signed Shokaken.
