[Not to be confused with the defunct THQ subsidiary Locomotive Games]
Locomotive Corporation, Ltd. (株式会社ロコモティブ) was a Kyoto-based development house started in May 1987 and headed by Hiroshi Okamoto (岡本博視). The company opened offices in Vietnam (involved in business software) and Cambodia (now Locomo) in 1995 and 1996 respectively.
In 2004, Okamoto co-founded Apria, a company that sells organic cosmetics. It is alleged he programmed the infamous Transformers game Convoy no Nazo for the Famicom.
