Yes, I'm asking for a name. The tale of Momotarou is based on someone who "existed" according to ancient Japanese texts (which means his historicity is debatable to some degree).

He is not the most famous hero of Japan, but he is the founder of a Japanese clan and he is an enshrined kami of two temples.
