Aisystem Tokyo (株式会社アイシステム東京) was a group company of Aisystem [1] [2] established on May 2, 1989. [3] Its head office was located near its parent company's in Matsudo, Chiba, while the development division was located in Chiyoda, Tokyo (hence the name of the company?). [4]

Aisystem Tokyo went bankrupt in 2005 [5] [6], but Aisystem remained in business and continued to operate the Go-Net online igo service and salon until August 2021. [7]

(We decided to write the name as "Aisystem" long ago, but Aisystem Tokyo and its parent company have written it inconsistently over the years [Ai System, AI-system].)

The following list is mostly derived from a company overview on the Aisystem Tokyo website. We have attempted to corroborate it by running code comparisons and looking at game credits and hidden data.

Arcade

  • Change Air Blade (programming?) (Sammy)
Sound: Fupac [8]
This is an educated guess. The company website just says "Air Blade." (Former NMK staff allegedly worked on this. [9])

  • Doki Doki Kingyo Sukui [medal game] (Sammy)
  • "Under Development"
