Edo Porn (Japanese: 北斎漫画, romanized: Hokusai manga) is a 1981 Japanese biographical drama film written and directed by Kaneto Shindō. It is based on Seiichi Yashiro's stage play on the life of Japanese artist Hokusai.^[1][2][3]

Tetsuzō is an unsuccessful ukiyo-e (woodblock) painter who lives in poverty with his daughter Ōei over a geta shop owned by Ōyaku, the older wife of the aspirant writer Sashichi, who is a childhood friend of Tetsuzō.

Tetsuzō lives by borrowing money from his adoptive father, mirror-maker Nakajima Ise. One day, he meets a young, beautiful prostitute named Ōnao and becomes fascinated with her. He produces a series of drawings of her, but later leaves her to Nakajima as a concubine. Ōnao, a sadist with a traumatic past, psychologically torments Nakajima until he hangs himself, and leaves.

After Ōyaku dies, Sashichi, adopting the pen name Bakin, devotes his life to writing and ignores Ōei's advances who has intimate feelings for him. Nevertheless, Ōei continues to love him, withdrawing to celibacy.

Years later and after hard-earned fame, Tetsuzō (now Hokusai) is 89. He lives by painting Ichimatsu dolls with Ōei. One day, Ōei finds a peasant girl who looks like Ōnao. 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.
