Project Rap Rabbit is a cancelled rhythm game formerly in development by NanaOn-Sha and iNiS for PlayStation 4 and Microsoft Windows. The game, directed by Masaya Matsuura in collaboration with Keiichi Yano, is pitched as a revival of story-based rhythm games such as PaRappa the Rapper and Gitaroo Man, and features rap battle gameplay mixed with Japanese culture. Following the game's failure to secure financing on crowdfunding website Kickstarter, the game's development has been placed on hold.
