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.

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.

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.

The original Jaleco company, Encom Holdings, quit the video game business in 2009, citing stiff competition in the industry, instead dealing in real estate.

They would continue to operate for several years as a subsidiary of PCCW, producing video games for home consoles and Japanese mobile phones, alongside soundtrack albums and applications for web browsers.

[7] In October 2007, Hyperlink Investments Group sold its stock in Jaleco Holding to Game Yarou, a Japanese mobile phone developer, and two South Korean corporations, STIC Pioneer Fund and A2i.

[10] By 2012, Game Yarou was in a financial crisis due to high debt and poor sales of their mobile titles – they were officially declared bankrupt by the Tokyo District Court on May 21, 2014.
