Japanese Boy Names
A Japanese boy name is really two things at once: a sound and a set of kanji. The same name, say Haruto, can be written dozens of ways, and parents choose characters for the meaning they carry — sun, soaring, sincerity, a great river. Below are more than 100 Japanese boy names, each with a common kanji spelling and what it means, grouped from today’s favorites to old samurai names.
Japanese naming trends move fast: the long -ro and -o endings of the 1950s have given way to airy, nature-heavy names like Minato and Asahi. For the full picture, see our main guide to Japanese names, browse Japanese girl names, or compare with Korean boy names.

How to choose a Japanese boy name
- Pick the kanji, not just the sound. If you have Japanese heritage, ask a relative or native speaker to help choose characters; Japan limits names to about 3,000 approved kanji.
- Say it with English speakers in mind. Names like Kai, Ken and Ren are easy everywhere, while Ryunosuke may be shortened to Ryu.
- Watch out for unintended meanings. Some sounds overlap with English words or slang; say the full name aloud with your surname.
- Respect the culture. If you don’t have a Japanese connection, choose a name for its real meaning rather than an anime character alone.
- Consider birth order names. Ichiro, Jiro and Saburo literally number sons, which can be charming or confusing depending on family size.
