Highwaystar Co., Ltd. (株式会社ハイウェイスター) was established in February 1996 and headed by Koichi Osafune (長船浩一), the former head of the digital entertainment division at adult video company Kuki. In 2003, a group of former staff established POT, originally an associated company of Highwaystar that later became independent.
Highwaystar is a Japanese developer and publisher founded in February 1996 by Koichi Osafune. His background includes leading the digital entertainment division at adult video company Kuki before starting his own studio. The company operated actively from 1999 to 2002, releasing ten games during this short window. Their output grew significantly over time, with only one game appearing in the 1990s and nine titles released throughout the 2000s. The studio focused heavily on PlayStation platforms, releasing nine games for the original console. They also made five releases each for PlayStation 3 and PlayStation Portable, along with a single title for Xbox. Their genre catalog is broad but leans toward sports simulations. Four of their games fall into the Sport category, while Arcade, Adventure, and Role-playing games account for two titles each. They also explored Simulator, Strategy, and Racing genres with one game in each. Despite this variety, critical reception was poor. The only rated title on record is Aces of the Air from 2002, which holds an average IGDB rating of 36 out of 100. This score places it firmly in the poor category. No games from their catalog achieved mixed, good, or great ratings according to available data. Recent releases from their final years include Drihoo in November 2002, Street Racquetball in June 2002, Mobile Armor in March 2002, and Simple 1500 Series Vol. 87: The Kyoutei in February 2002. In 2003, a group of former staff members left to establish POT as an associated company. This new entity later became independent. Highwaystar itself did not release any games after 2002. Their brief history shows a rapid rise and fall within the console market. The low rating for their most notable work suggests their output struggled to meet quality expectations. Players browsing PlayPile will find a small library from this developer that covers many genres but lacks critical acclaim.
