Japanese boy names

A Japanese name means whatever its characters mean, and the same sound can be written a dozen different ways. Haruto, Yuto and Kenji are sounds first; the kanji a family registers decide what the name says. This page gives the writing where one genuinely dominates, says so plainly where none does, and covers 30 names with real pronunciation.

Japanese names in the U.S. top 100

One, and it is only partly Japanese. Everything else on this page sits outside the current U.S. top 100 — several of these names are ordinary in Japan and almost unheard of in America, which is a different thing from rare.

#93KaiKYSeveral origins
Four unrelated names that arrive at the same three letters: Hawaiian kai, the sea; Mandarin kǎi, triumph; Danish and Frisian Kaj, derivation unsettled; and in Japan a sound written 海 sea, 開 open or 貝 shell, depending on the family.

Names the kanji decide

These are the names other name sites get wrong. Each one is a pronunciation that several character combinations share, so no single gloss is the meaning — the commonest writings below are examples, not definitions.

HarutoHAH-roo-tohJapanese
The clearest case on the page. 陽翔 is sun and soaring, 大翔 is big and soaring, 春翔 is spring and soaring. One sound, three boys, three meanings.
YutoYOO-tohJapanese
The writing decides. 悠 for the unhurried and 優 for the gentle and excellent are two of the usual first characters, and neither of them is the definition of the name.
KaitoKYE-tohJapanese
The great majority of Kaitos open with 海, the sea — but the second character is a free choice, so sea-and-dipper and sea-and-soar are both Kaito.
HarukiHAH-roo-keeJapanese
Most familiar as 春樹, spring tree, which is how the novelist Haruki Murakami writes it. Other families write the same sound to mean other things.
KenjiKEN-jeeJapanese
健二 is healthy and second-born, 賢治 is wise and governing, 謙二 is modest. All three men are Kenji, and none of the three glosses is the name.
KenzoKEN-zohJapanese
Healthy, wise or humble, joined to 三 for a third son or 蔵 for a storehouse. The designer Kenzo Takada wrote his 賢三, wise and third.
ShoSHOHJapanese
翔, to soar, is the modern favourite; 将, a commander, is the older one. The baseball player Shohei Ohtani carries the soaring character.
SotaSOH-tahJapanese
Usually 颯太 — 颯, a brisk gust of wind, finished with 太, the "big" character that closes a great many Japanese boys' names.
Takumitah-KOO-meeJapanese
匠, the master craftsman, is the gloss everyone quotes. The commonest modern spellings are built on 拓, to open up: 拓海 is a boy named for opening the sea, not for cabinetmaking.

Traditional names

The older stock — the birth-order names, the plain adjectives, and the two-character men's names that filled Japanese registers before the war. Several are now period markers in Japan: a Japanese speaker hearing Ichiro or Taro pictures a grandfather.

IchiroEE-chee-rohJapanese
First son, 一郎, at the head of the old counting series: Ichiro, Jiro, Saburo, Shiro, Goro. Ichiro Suzuki made it a one-word name in two countries.
TaroTAH-rohJapanese
太 great plus 郎 son: the grander way to name a first boy. Taro is also Japan's John Doe, the name printed on every specimen form.
AkiraAH-kee-rahJapanese
Bright, clear — usually 明, the sun written beside the moon. The director Akira Kurosawa wrote it exactly that way.
TakeshiTAH-keh-sheeJapanese
Valiant. An old Japanese adjective standing as a name with nothing added to it, most often written 武 or 猛.
TakeoTAH-keh-ohJapanese
Commonly valiant man, from 武雄. The sense moves with the characters, but the 雄 ending marks it as a man's name whichever pair is chosen.
MakotoMAH-koh-tohJapanese
Sincerity, truth, the genuine article — an ordinary Japanese word pressed into service as a name. Given to daughters as well as sons.
Satoshisah-TOH-sheeJapanese
Quick of understanding. Unusually for a Japanese name, the writings vary — 聡, 智, 悟 — and every one of them lands in the same field of sense.
HayatoHAH-yah-tohJapanese
Falcon person, 隼人. The Hayato were also a people of southern Kyushu whom the early Japanese court spent two centuries subduing.
RyuRYOOJapanese
Dragon. 竜 and 龍 are the two characters that dominate the name, one the simplified form of the other, and both name the same beast.
Yamatoyah-MAH-tohJapanese
Great harmony, 大和 — and the oldest name Japan had for itself, from the Nara-basin province where the court first pulled the islands together. As a name for a child it is recent.

Names that are already words

The current fashion in Japan runs to short, transparent nature words. These are the exceptions to everything above: the word is fixed, so no choice of characters will make the name mean anything else.

MinatoMEE-nah-tohJapanese
A harbour, and nothing else. Old Japanese mi-na-to, the water-gate. Maps write it 港; parents almost always write 湊, the older character.
RikuREE-kooJapanese
Land, 陸 — dry ground as against sea and sky. Japanese parents pair it deliberately against Sora and Kaito for brothers.
SoraSOH-rahJapanese
Sky, 空. Read the Chinese way the same character is kū, empty — the sky being the part of the world that nothing occupies.
NagiNAH-gheeJapanese
The calm. 凪 is wind with 止 "stop" written inside it, and it names a specific event: the windless interval at dawn or dusk when land and sea breezes change places.
RenRENJapanese
The lotus, 蓮 — the flower that comes up clean out of pond mud. One character, one syllable, and one of the most registered boys' names in Japan.
Tsubasatsoo-BAH-sahJapanese
Wing, 翼. A plain noun used as a name without alteration, and given to both boys and girls.
ItsukiEE-tsoo-keeJapanese
A standing, living tree — the sense of 樹, the character almost every Itsuki is written with.
HinataHEE-nah-tahJapanese
A sunny place; the side of things turned toward the sun, 日向. Fully unisex in Japan.
AsahiAH-sah-heeJapanese
The morning sun, 旭 or 朝日. The same word runs across a national newspaper masthead and a great many beer bottles.
DaichiDYE-cheeJapanese
Great earth, 大地 — the ground itself, the wide land, with no sense of country attached.

How Japanese naming works

A Japanese name is chosen as characters, not as a sound, and the law knows it. The Ministry of Justice publishes a list of kanji permitted in given names — the everyday jōyō set plus a few hundred extra characters approved only for names — and a ward office will refuse a birth registration that uses anything outside it. What the register has historically not fixed is how those characters are said, because kanji carry several readings each and parents may assign the one they like. That is the loophole behind the kirakira or "sparkly" names that Japanese newspapers periodically get exercised about, and it is also why a Japanese business card usually prints the name twice: once in characters and once in kana, so that the recipient knows how to say it.

Two other things surprise English speakers. There is no middle name — the family register has one surname field and one given-name field, and that is the whole of it — and the surname comes first at home, so Ichiro Suzuki is Suzuki Ichiro in Japanese. Fashion, meanwhile, moves in clean waves. The -rō endings of Taro and Jiro ran the registers until the 1960s; a -shi and -ki generation followed; and since the 2000s the favourites have been two-mora names ending in -to and single characters taken straight from the landscape — Minato, Riku, Ren, Nagi. Set against Chinese and Korean practice on the origins index, the Japanese system is the loosest of the three: the same characters, far more freedom in how to read them.
