Eikoh Hosoe, (b. 1933) is a Japanese photographer and filmmaker who emerged in the experimental arts movement of post-WWII Japan. He is known for his psychologically charged images, often exploring subjects such as death, erotic obsession, and irrationality. Through his friendships and artistic collaborations he is linked with other 1960s avant-garde artists such as the writer Mishima Yukio, and the dancer Hijikata Tatsumi.

In 1960, Eikoh created the Jazz Film Laboratory (Jazzu Eiga Jikken-shitsu) with Hijikata, Terauama Shuji, and Tomatsu Shomei. The Jazz Film Laboratory was a multidisciplinary artistic project aimed at producing highly expressive and intense works such as Eikoh's 1960 short black and white film Navel and A-Bomb.

With Hijikata Tatsumi, Eikoh created Kamaitachi, a series of images that reference stories of a supernatural being--'weasel-sickle'--that haunted the Japanese countryside of Eikoh's childhood. In the photographs, Hijikata is seen as a wandering ghost mirroring the stark landscape and confronting farmers and children.

With Mishima as a model, Eikoh created a series of dark, erotic images centered around the male body known as Ordeal by Roses (1963). The series (set in Mishima's own Tokyo house) positions Mishima in sacrificial, promiscuous, wretched, and cruel states. Mishima would follow his own obsessional interest in death and extreme physical states, eventually committing suicide by seppuku in 1970.
