What is "nanaon-sha"

is a Japanese video game company which created what is widely credited as the first modern rhythm game, PaRappa the Rapper. It was founded by Masaya Matsuura in 1993. The game's success resulted in the spinoff UmJammer Lammy, which is based on guitar samples, and eventually a proper sequel, PaRappa the Rapper 2. NanaOn-Sha also produced another novel music game, Vib-Ribbon, but released the game only in Japan and the PAL region.

"Nana On Sha" roughly translates into "seventh sound company" from Japanese.
