Molester Invisible Man IV: Deepest Depths

Tahei becomes an invisible man the moment he drinks a mysterious potion. In the first part of the film, it depicts daring sexual encounters and lesbian affairs involving women who proudly maintain respectable images—namely a female police officer and a nun. In the second part, Tahei, now working as a traveling salesman in rural areas, finds himself embroiled in a series of outrageous molestation escapades when he encounters two intriguingly nicknamed women: one called “A Thousand Earthworms” and another known as “Three-Tiered Drawstring Choke” (both epithets referring to their notably alluring attributes). Born from the outlandish idea of using invisibility to freely indulge in molestation and tryst, this work is an unconventional and idiosyncratic pornographic film designed to fulfill the secret desires of men.

Directed by Kōji Seki, Molester Invisible Man IV: Deepest Depths leans on a strong ensemble — Yuko Nakagawa, Mieko Aoki — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about screen titles of 1981.
