Momotarou Collection is likely a compilation or anthology game based on the Japanese folktale of Momotaro. It likely consists of different mini games or versions of games, each loosely based on the Momotaro story, with each game offering a unique style of play and challenges. Given the title, it's a very Japanese themed game and would therefore likely have a Japanese developer and publisher.
