Jaleco
Japanese video game publisher and developer

Jaleco Ltd. (株式会社ジャレコ, Kabushiki Kaisha Jareko) 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 its 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 its 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 its 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.
In 2014, Jaleco's parent company Game Yarou filed for bankruptcy, causing Jaleco to vanish from the video game industry.

Why this record matters
The phrase “japanese video game publisher and developer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q1344080. VIAF identifies the subject as 149331153. Authority coordinates are 35.623, 139.724. 4 of 7 selected statements include explicit references; 5 carry qualifiers and 1 use preferred rank. The first chronological checks are 1974, 2000, 2002 and 2006.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
