MIA was a small Japanese software developer and publisher active in the early 1980s.

The company produced games for domestic home computers such as the PC-6001, distributing its titles primarily on cassette tape.

MIA is known for releasing ONION HOUSE (originally titled Circumference) in 1983, a semi-real-time adventure game featuring a hybrid system that combined command-based input with real-time elements.

Little verified information remains regarding the company’s founding year, corporate structure, or personnel, and no official company logo has been confirmed.

Due to the limited availability of primary sources, MIA is generally regarded as a short-lived or very small-scale developer from the early Japanese PC game era.
