Japanese moon names are some of the most graceful in the language – short, soft, and built around a single character, 月, that has been written into poetry, festivals and folktales for over a thousand years. A name that means moon suits a night-born baby, a quiet and thoughtful child, or a fantasy character with a silver edge.
This guide collects 40+ Japanese names meaning moon for girls, boys and unisex use – Tsukiko, Mitsuki, Mikazuki, Tsukuyomi and rarer picks from the old lunar calendar. Almost every entry shows the kanji, because in Japanese the same sound can mean very different things depending on how it is written. Three honest notes before you start: the character 月 means both moon and month, so many so-called moon names (Hazuki, Satsuki) are really month names; Akari, Hikari and Hotaru are often listed as moon names but mean light and firefly; and Luna is Latin, not Japanese – the closest modern Japanese form is Runa.

Girl names meaning moon
Most Japanese moon names lean feminine, and the strongest are built from 月 plus one other character. The kanji matter: a name like Mizuki can be written many ways, and only some of them mean moon.
| Name | Kanji | Meaning & notes |
|---|---|---|
| Tsukiko | 月子 | Moon child (tsuki + ko, child). The -ko ending is the traditional Japanese girl-name suffix |
| Tsukino | 月乃 | Of the moon (tsuki + no, possessive). As a surname, 月野 means moon field – the family name of Usagi Tsukino in Sailor Moon |
| Tsukika | 月花 | Moon flower (tsuki + ka, flower) |
| Tsukiyo | 月夜 | Moonlit night; also an everyday Japanese word for a night lit by the moon |
| Mitsuki | 美月 | Beautiful moon (mi, beautiful + tsuki). Used for girls and boys; the same sound is written with other kanji too |
| Mizuki | 水月 | Water moon (mizu + tsuki). Mizuki is also written with kanji that do not mean moon at all, so check the characters |
| Yuzuki | 優月 | Gentle moon (yu, gentle + tsuki). Other spellings include 柚月 (yuzu citrus + moon) and 結月 (tie + moon) |
| Hazuki | 葉月 | Leaf month – the traditional name of the eighth lunar month (roughly August). A month name that uses the moon character |
| Kaguya | かぐや | The heroine of The Tale of the Bamboo Cutter, a princess from the moon. The exact origin of the word is debated by scholars |
| Runa | varies | A modern pick – the Japanese form of Luna. Some parents write it with 月 (moon) and give the character an imported reading, part of the kirakira naming trend |
| Mikazuki | 三日月 | Crescent moon, literally the third-day moon (mika + zuki) |
| Oboro | 朧 | Hazy, misty – the word for a moon veiled in spring haze (oborozuki) |
| Izayoi | 十六夜 | Sixteenth night – the moon on the night after full, said to rise a little hesitantly |
| Gekka | 月下 | Under the moon. Gekka Bijin (月下美人) is the night-blooming cereus, a flower that opens only at night |

How to choose a Japanese moon name
Choose the kanji, not just the sound. Mizuki and Mitsuki are written many ways, and only some mean moon. Write the characters down before you commit – the meaning lives in the kanji.
Check how it sounds outside Japan. Tsuki, Mitsuki and Mizuki are easy for English speakers. Tsukiyo and Tsukuyomi take a moment longer – not a problem, just something to know.
Treat gods with respect. Tsukuyomi is a real Shinto deity. On a character it adds depth; on a baby it invites questions, which may be exactly what you want.
Pair moon with another element. Moon names go beautifully with names from the rest of the sky: see our names that mean night and boy names that mean light for matching middle names.
Our takes: the best moon name for every situation
For a baby girl: Tsukiko or Mitsuki – classic, graceful and easy to wear abroad.
For a baby boy: Tsuki or Mikazuki – short, balanced and unmistakably lunar.
For a character: Tsukuyomi, Kaguya or Izayoi – names with built-in mythology.
For the bold: Oboro, Gekka or Kannazuki – rare, atmospheric and full of story.
