Jorudan

Jorudan Co., Ltd. (ジョルダン株式会社) is a software company based in Shinjuku, Tokyo. Toshikazu Sato (佐藤俊和) is the president and CEO. [1] Until December 1989, the company was known as Jordan Information Service Co., Ltd. (株式会社ジョルダン情報サービス). [2] (The company name is derived from the French mathematician Camille Jordan. [3])

Jorudan was established in December 1979 [4] by Sato, along with Mitsuo Honda (本田光雄) (later a manager at Jorudan; now deceased) [5] and at least one other person. [6] They previously worked for a company called SG [7], which made office computers and later turned to contract software development. [8]

A manufacturer came to SG wanting to make a game, initially one similar to Space Invaders. However, Sato's colleagues were strongly opposed to developing video games, so Sato formed an independent team to develop them. They proceeded to make the racing game Rolling Crash for Nichibutsu to much acclaim, but the atmosphere at SG remained hostile, so they decided to start their own company. [9]

Among the earliest products by Jorudan were the arcade game Crazy Climber (also for Nichibutsu) and English learning software for NEC's PC-8000 series of computers. [10] Today, the company's main focus is its navigation apps Norikae Annai and Japan Transit Planner. [11]

For many years, Jorudan developed and later published video games. It pulled out of the game industry in 2004, but announced its return to the console game business in 2007, concentrating on the Nintendo DS and Wii. [12] The return was short-lived, however; Jorudan's last game was published in 2009. [13]

In February 1999, Jorudan started a subsidiary called Nekogumi Co., Ltd. (株式会社ねこぐみ) to strengthen game development. It was liquidated in March 2001. [14]
