“Kusakabe Kimbei (1841 – 1934) was a Japanese photographer. He usually went by his given name, Kimbei, because his clientele, mostly non-Japanese-speaking foreign residents and visitors, found it easier to pronounce than his family name. Kusakabe Kimbei worked with Felice Beato and Baron Raimund von Stillfried as a photographic colourist and assistant before opening his own workshop in Yokohama in 1881 in the Benten-dōri quarter, and from 1889 operating in the Honmachi quarter. He also opened a branch in the Ginza quarter of Tokyo”. – Wikipedia
