About this list
Japanese boy names have a great energy to them, thanks to those bright, bold, bouncy vowel endings. The appetite in the West for all things Japanese has exploded in recent years, and that’s just starting to extend to stylish Japanese baby names, too.
The Japanese names for boys that chart in the US tend to be those with cultural crossover, like Asa and Kane, which also have Hebrew and Celtic roots, respectively.
Along with Asa and Kane, other popular Japanese boy names include Kai, Raiden, Ren, and Koda. Baby boy names popular in Japan include Haruki — known to Americans as the first name of author Murakami — Riku, Toma, and Haruto.
Japanese baby names for boys also include several super-cool K options which feel bang on-trend in the US right now — we’re loving Kazuo, Kenzo, Koda and Kenji as exotic alternatives to the Kayden family of names.
