NIGHT LIFE

Released in 1982 by Koei (now Koei Tecmo Games), "Night Life" is a historic title recognized as a pioneer of adult software in Japan. Marketed as a utility program to support married life, the software included features such as calculating safe periods and suggesting sexual positions. It was an extremely experimental project that went beyond the framework of traditional gaming and holds significant historical value as a document of the dawn of Japanese PC gaming culture. This unique title offers a glimpse into the trial-and-error development environment of the early 1980s.

This program is considered one of Japan’s earliest utility software titles, designed to support marital harmony and health management. Players receive advice on enriching their private life, including the calculation of fertility cycles and suggested positions based on physical condition. While it lacks a narrative progression or a specific protagonist, it served as a practical tool intended to assist with communication in the bedroom for households of the era.
