A. Incest as the Inescapable Family Bond Kumashiro returns to incestuous dynamics obsessively, treating them not as perversion but as the logical endpoint of the closed, authoritarian Japanese family.

Tatsumi Kumashiro (1927–1995) is a towering, if provocatively complex, figure in post-war Japanese cinema. Often categorized as a director of Roman Porno (Nikkatsu’s soft-core erotic film series), Kumashiro transcends the genre’s commercial constraints. His œuvre is a systematic, humanist, and frequently unsettling exploration of what he termed the “fundamental immorality” of human desire. This report examines how Kumashiro uses depictions of “immoral and indecent relations”—including incest, adultery, prostitution, and sexual obsession—not for simple titillation, but as a radical critique of Japanese social hypocrisy, patriarchal family structures, and the repressed trauma of modernity.
