System Sacom (システムサコム?), also known as System Sacom Sales Corp., is a Japanese company which sells electronic devices. They are more notable for their past, in which they developed video games. In the eighties, they mainly published games for computers, but they changed focus to home consoles in the nineties. Its head office is located in Tokyo.
Sacom had particular success with their Novel Ware (ノベルウェア?) series, which had tremendous effect within the sound novel and visual novel genres. In the series, they tried to create a fusion of sound and the written word. For example, in a time when most companies were still using FM synthesizers integrated with early Japanese computers, Sacom had progressed to using MIDI.
When the Famicom Disk System was popular, Sacom was a member of DOG (Disk Original Group), of which Square was a prominent member.
