The Embryo Hunts in Secret (胎児が密猟する時, Taiji ga Mitsuryō Suru Toki), released July 1966, is the first film Kōji Wakamatsu made independently of any studio—months after leaving Nikkatsu and founding Wakamatsu Productions. He was quoted at the time: “For me, violence, the body and sex are an integral part of life”—a line that maps cleanly onto the plot of captivity, bondage, and revenge. For pink-film and BDSM-media history, it is early independent Japanese softcore as private torture chamber: rope, razor, forced nudity, and a woman who finally turns the tables.
Plot: Apartment Captivity, Bondage, and Revenge
A mentally unstable man keeps his girlfriend tied in his small apartment and tortures her. He prefers her naked; she endures various types of bondage, whipping, and razor cuts. He also brushes her hair and applies makeup—care and cruelty alternating inside the same sealed room as his sanity collapses. The film tracks that breakdown as closely as the abuse itself. In the end she frees herself and takes revenge. The structure is power-exchange nightmare without negotiation: captivity as relationship, grooming as control, escape as the only “aftercare.” For modern kink viewers it is not a how-to and not SSC fantasy; it is pink-film SM as psychological horror, with the apartment as a self-built dungeon and the razor as the line between eroticized violence and murderous collapse.
Cast
- Hatsuo Yamaya (山谷初男)
- Miharu Shima (志摩みはる)
The small cast keeps the film claustrophobic: two bodies, one room, no studio cavalry. That economy is part of what made early Wakamatsu Productions portable—and brutal.
Legacy: Early Stalker Cinema and Pink SM
The film is often cited as one of the early examples of the “stalker film,” decades before that label became a Western genre marketing term. Jack Hunter’s Eros In Hell: Sex, Blood And Violence In Japanese Cinema (Creation Books, 1998) places it in the continuum of Japanese sex, blood, and violence cinema. For BDSM-media readers, Embryo matters less as lifestyle endorsement than as a founding independent pink title where bondage and razor torture are the grammar of a private power crime—and where revenge, not reconciliation, closes the loop. Wakamatsu’s quote about violence, body, and sex as integral to life remains the blunt epigraph for a career that would keep pushing political softcore and underground extremity from that 1966 break with Nikkatsu onward.
