Nana On Sha is a development studio formed by Parappa The Rapper mastermind Masaya Matsura. Nana On-Sha has worked on quirky titles like Mojib Ribbon and Vib Ripple. The company is usually thought of a developer for Sony, but Nana On-Sha has produced titles for Bandai and other companies, as well as the Nintendo DS version of Tamagotchi.

In addition to producing games, Nana On-Sha has also published many soundtracks, books, PC productivity packs and other releases based on its titles. Matsura has also produced several records put out by Sony (with singles that include Mint-Electric and Emotional Engine.)
