Izumi-ya Ichibei (c. 1686-1886) is among the most successful and productive publishers in the history of Japanese woodblock prints. Izumiya Ichibei was a founder member of the Picture Book and Print Publishers Guild Jihon toiya. He was a censor of prints in 1812 to 1813. From 1876, Izuyama sealed their prints Yamanaka Ichibei (the family name). Ichibei started publishing prints around 1776 with actor and beauty prints by Kiyonaga and Shuncho, and Toyokuni designed several important series of actor prints in the 1790s. Utamaro, Eiri, Eizan and later Utamaro II, Eisen and Kunisada produced designs for bijin-ga. The great landscape designers Hokusai and Hiroshige also worked for Izumiya. See Andreas Marks.
