Jaleco

was a corporate brand name that was used by two previously connected video game developers and publishers based in Japan. The original Jaleco company was founded in 1974 as Japan Leisure Company, founded by Yoshiaki Kanazawa, before being renamed to simply Jaleco in the early 1980s. This company was later acquired in 2000 by Hong Kong company PCCW, who rebranded it as their Japanese game division, PCCW Japan, before reverting it to Jaleco in 2002. In 2006, Jaleco became independent from PCCW and renamed to Jaleco Holding, having their video game operations spun off into a new company, also called Jaleco. This new spin-off company was sold to mobile developer Game Yarou in 2009, with Jaleco Holding renaming itself to Encom Holdings shortly after.

Jaleco is known for its arcade and home console video games produced in the 1980s and early 1990s, including City Connection, Bases Loaded, Ninja JaJaMaru-kun, Exerion, Idol Janshi Suchie-Pai and Rushing Beat. Jaleco also produced arcade cabinets for other game developers, alongside redemption arcade games and UFO catcher claw machines. In the past, the company produced amusement park equipment and aquarium parts, under their JAQNO brand name. Their North American division, Jaleco USA, published a number of titles for the NES and SNES, including Maniac Mansion, Pinball Quest and R-Type III.
