Meaning & Origin
Hiro is a boy's and girl's baby name of Japanese origin, from the Japanese characters hiro (宏, vast) or hiro (寛, generous, tolerant) or hiro (博, extensive knowledge), each giving the name a different but equally admirable meaning. Hiro is a common component of Japanese compound names and increasingly used as a standalone given name.
Hiro gained Western pop culture visibility through the beloved character Hiro Hamada in Big Hero 6 and Hiro Nakamura in Heroes. It is short, clean, and carries a genuine Japanese identity that translates beautifully across cultures.
