NanaOn-Sha

NanaOn-Sha (株式会社七音社) is a Japanese video game developer founded by Masaya Matsuura in 1993.

History
In 1993, Matsuura founded the Tokyo-based production company, NanaOn-Sha, which began the development of video games. He was mainly involved in the development of the industry but in various sound productions, including his music activities.

They debuted the release of Tunin'Glue in 1996 for the Apple Pippin, which is only released in Japan. They've also developed PaRappa the Rapper for the PlayStation—the same year as Tunin'Glue—which marks their collaborative debut with Californian visual artist Rodney Greenblat. Successfully regarded as the first modern music video game, the game was initiated as a franchise, which included a spin-off, Um Jammer Lammy–which is based on guitar samples–and eventually a proper sequel, PaRappa the Rapper 2.

In 1999, they also developed Vib-Ribbon. Only released in Japan and PAL reigons, the game was later released in North America on the PSN store under the PS1 classic in 2014.
