Edo Porn () is a 1981 Japanese biographical drama film written and directed by Kaneto Shindà Â. It is based on Seiichi Yashiro's stage play on the life of Japanese artist Hokusai.
Tetsuzà  is an unsuccessful ukiyo-e (woodblock) painter who lives in poverty with his daughter à Âei over a geta shop owned by à Âyaku, the older wife of the aspirant writer Sashichi, who is a childhood friend of Tetsuzà Â.
Tetsuzà  lives by borrowing money from his adoptive father, mirror-maker Nakajima Ise. One day, he meets a young, beautiful prostitute named à Ânao and becomes fascinated with her. He produces a series of drawings of her, but later leaves her to Nakajima as a concubine. à Ânao, a sadist with a traumatic past, psychologically torments Nakajima until he hangs himself, and leaves.
After à Âyaku dies, Sashichi, adopting the pen name Bakin, devotes his life to writing and ignores à Âei's advances who has intimate feelings for him. Nevertheless, à Âei continues to love him, withdrawing to celibacy.
Years later and after hard-earned fame, Tetsuzà  (now Hokusai) is 89. He lives by painting Ichimatsu dolls with à Âei. One day, à Âei finds a peasant girl who looks like à Ânao. After he sees a young ama (pearl diver) playing with a dead octopus, Hokusai persuades the girl to pose for the shunga (erotic art) of an ama engaged in a threesome with two octopuses.
