Band-kun (バンドくん, loosely translated as "Mr. Band") is Koei's first attempt to create a music video game. It is the first title to be branded with the "Sound Entertainment" label, the other being Life is Music. Eiji Fukuzawa is the credited producer. A MIDI board is required to run the game, which was a separate approximate 30,000 yen purchase for computers at the time of the game's initial availability. Many consumers were not willing to buy it and caused Band-kun to fade into obscurity, a flaw later acknowledged by Keiko Erikawa during Gitaroo-Man's press conferences.
