OP Eiga

"OP Eiga" is a Japanese film subgenre, primarily associated with softcore pornography, that emerged and gained popularity in the late 1970s and 1980s. The term "OP" is derived from "Oppai," a slang word for breasts. Therefore, OP Eiga films prominently feature nude or semi-nude women and focus heavily on breast exposure and related sexual content.

The genre distinguishes itself from other forms of Japanese erotica through its specific emphasis on the breasts, often employing techniques like close-up shots and slow-motion sequences to highlight them. Storylines, if present, are typically simple and serve as a framework for showcasing the female form.

OP Eiga films are often characterized by their low budgets and production values. They were typically released directly to video or shown in smaller theaters catering to adult audiences. While still produced, the genre has largely been overshadowed by other forms of adult entertainment and has seen a decline in popularity since its peak.

It's important to note that OP Eiga films are distinct from mainstream Japanese cinema and are primarily targeted toward a specific niche audience. The genre reflects a particular aspect of Japanese sexual culture and its representation in media.
