Chobunsai Eishi (1756-1829) was a Japanese ukiyo-e artist. Born Hosoda Tokitomi to a well-off samurai family from the prestigious Fujiwara clan, Eishi became family head when his father died in 1772, and from there he held a position in the palace of Shogun Tokugawa Ieharu. Eishi appeared to have studied art under Kano Michinobu of the Kano school, and he left the official service of the Shogun in 1784 to pursue his artistic talents, giving up his samurai rank. His earliest works were nishki-e prints of literary fare such as 'The Tale of Genji', but he soon went to specialise in bijinga portraits of women. Eishi also occasionally illustrated books of shunga erotica. He abandoned woodblock printing for painting sometime after 1801.
