Japanese Baby Names, With Meanings and Data

Why a Japanese name's meaning is not fixed by its sound

This is the single most important thing to understand, and most English-language name lists skip it. A Japanese given name is normally written in kanji, characters borrowed from Chinese, and the meaning belongs to the characters rather than to the pronunciation. The name Haruto can be written with characters meaning "spring" and "person", or "sunlight" and "soar", among many other combinations. Two children with the identical spoken name can have names that mean quite different things.

The reverse also holds: the same characters can be read several ways. This is why Japanese forms often ask for a name's reading separately from its writing, and why any list that gives one English gloss per Japanese name is simplifying something the language treats as open.

The law is unusually specific

Japan restricts which characters may be used. Under the enforcement rules of the Family Register Act, a child's name may use characters from the jōyō kanji list and the jinmeiyō kanji list — the list of characters approved specifically for personal names — plus hiragana and katakana. The Ministry of Justice publishes the approved list and a search tool for checking a character. Nothing comparable exists in the UK, where the constraint is practical rather than statutory.

Japanese names, and how they fare in Britain

Japan does not publish an official baby-name ranking; the annual lists circulated each year come from insurance companies and publishers rather than from a government statistics body, so we have not reproduced one. What can be cited is the Office for National Statistics data for England and Wales, covering births registered in 2025 and published on 9 July 2026. The numbers are small, and that is the point.

What the figures show

Almost all of these are genuinely rare in Britain

The ONS suppresses any name given to fewer than three babies, and several well-known Japanese names — Haruto, Sota, Yui, Miyu, Hinata, Ichika, Riku, Taro — did not clear that threshold in England and Wales in 2025 at all. Ren at 93 boys and Hana at 341 girls are the only entries here with substantial numbers, and in both cases some of that comes from families with no connection to Japan: Hana is also a common Arabic, Persian and Czech name.

Kai is the crossover case

Kai went to 672 boys in England and Wales in 2025, more than every other name on this page combined. It is genuinely a Japanese name, and it is also independently a Hawaiian name meaning "sea", a Frisian short form and a Chinese name. Almost none of its British use is specifically Japanese, which makes it a good illustration of how a sound can become popular in one country while carrying an entirely different origin in another.

Movement, on two dated points

Comparing the ONS 2024 and 2025 files: Sakura rose from 6 girls to 10, Yuna from 30 to 37, Sora from 3 boys to 6 and Rin from fewer than three to 5, while Kaito fell from 14 to 10, Ryu from 15 to 8 and Kai from 735 to 672. At these numbers, a change of two or three babies moves a name hundreds of places in the rankings, so none of this should be read as a trend.

Some names are used for both sexes

Akira, Hikaru, Kaoru and Makoto are given to boys and girls in Japan, and the characters chosen usually signal which is intended rather than the sound. In Britain that signal disappears entirely, so a Japanese name that reads as clearly masculine or feminine in Tokyo may read as neither here. Akira went to 8 boys and 26 girls in England and Wales in 2025.

Choosing a Japanese name

Decide whether you are choosing a sound or a name. If your family has no Japanese connection and the name will only ever be written in the Latin alphabet, you are choosing a sound, and the meaning attached to it in an English list is one of several possible writings. That is a legitimate choice, but it is worth being clear-eyed that the character-level meaning is not travelling with it.

If the name will be registered in Japan as well, check the characters and the reading with the Ministry of Justice list before you commit, because the permitted set is finite and a rejected character means a rejected registration.

Finally, be careful with the -ko ending. Names such as Aiko, Keiko, Yoko and Naoko were dominant in Japan for much of the twentieth century and have fallen sharply out of use there since. To a Japanese speaker they read as belonging to a particular generation in the way that Susan or Deborah do in Britain, which is invisible from an English-language list.
