Few tasks carry as much quiet hope as naming a child, and Japan’s naming culture turns that hope into a kind of art. The 2025 baby-name rankings put Minato and Sui at the top for the first time.
Most popular boy name (2022): Haruto · Most popular girl name (2022): Riko · Kanji approved for names: ~2,998 characters · Typical name order: Surname first, given name second · Names using kanji: ~90%
Quick snapshot

What are the most popular Japanese boy names?
Two surveys, two different lists — that’s the first thing to know about boys’ names in 2025.
What the 2025 surveys say
- Meiji Yasuda’s annual survey, reported by Nippon.com’s Japan-data desk, put Minato first among boys’ written names; Iori and Yuito tied for second, and Ren came fifth.
- The Tamahiyo/Benesse ranking placed Ao first, with the name meaning “deep blue” or “azure” (The Japan Times, English-language daily).
- Sankei Shimbun’s coverage of the Meiji Yasuda results notes that Minato’s kanji reads as “harbor,” a place where water gathers (Sankei Shimbun, national daily).
What the -to pattern tells you
- The earlier 2020s were defined by -to names such as Haruto, Kaito, and Rikuto.
- The newest rankings shift toward short, single-kanji choices, suggesting a move from trendy suffixes to image-forward names.
If you’re choosing between a name like Haruto and one like Minato, the data says you’re deciding between a moment of trend and a longer shift toward nature and simplicity.
The pattern: 2025 rewards short, image-rich names; the old -to wave hasn’t collapsed, but it’s no longer the headline.
What are the most common Japanese girl names?
Girls’ names in 2025 lean short, visual, and nature-heavy.
Top girls’ names in 2025
- The Meiji Yasuda 2025 series placed Sui first, Himari second, and Tsumugi third.
- Tamahiyo/Benesse also placed Sui first among girls’ written names (The Japan Times, English-language daily).
- In 2022, Riko was the top girl’s name in the same broader series, showing how quickly the top spot can move.
Why -ko faded
- Traditional -ko names like Satoko remain recognizable but are less common on new birth registers.
- Nature-based names such as Aoi, Rin, and Hana have risen alongside color names like Sui and Ao.
Girls’ names are pulling away from the old -ko convention and toward words that feel like small poems: jade, hollyhock, azure.
What this means: a girl named Sui in 2025 carries a different message than a girl named Satoko in 1985 — her name is chosen to be short and sensory.
What Japanese names have dark meanings?
Search interest in dark Japanese names is mostly fiction-driven.
The names people search for
- Names like Yami, meaning darkness, and Shinigami, meaning death god, appear in online lists but are exceptionally rare on Japanese birth certificates.
- Manga, anime, and role-playing games are where such names thrive, which explains most of the search volume.
How kanji can turn a good name dark
- Because one pronunciation can map to many kanji, a sound that feels soft in speech can look heavy on paper.
- A positive-sounding name can still create an unintended impression if the written characters carry unfortunate combinations.
A “dark” Japanese name can sound powerful in a story, but in Japan it can follow a child through school, job applications, and daily introductions.
The implication: dark-meaning names are a fiction-first category; they tell you more about manga plots than naming norms.
What are rare Japanese names?
Rarity in Japanese names often comes from reading, not spelling.
Yutōyomi and invented names
- Yutōyomi refers to non-standard kanji readings used mainly in names, so a common character can feel completely fresh.
- Some parents create kosei names by combining kanji in new ways, producing a name that has no prior history.
- The legal name space still sits inside the Jinmeiyō list of approved kanji, so creativity is bounded.
Rare outside Japan, common inside
- Names like Tsubasa, Sora, and Hikari can feel distinctive internationally but are part of Japan’s everyday name pool.
- Actress Miku Martineau, whose first name is a recognizable Japanese girl’s name, is one international example (read Miku Martineau’s profile on Canada Scene).
Rare Japanese names are mostly rare because of reading rather than characters; a name like Sora is simple, while a created reading can turn familiar kanji into something puzzling.
The catch: yutōyomi names can be beautiful but may mean a lifetime of correcting pronunciation.
What Japanese names start with A?
For many parents, A-initial names hit a sweet spot between meaning and sound.
Boys’ names beginning with A
- Akira (bright, intelligent) is a classic with many kanji spellings.
- Arata (fresh, new) and Asahi (morning sun) fit the modern nature trend.
- Akihiko remains a traditional -hiko name still in circulation.
Girls’ names beginning with A
- Aoi (hollyhock or blue) tops many short name lists.
- Ami (friend, beautiful) and Ayaka (color, flower) remain common.
- Azumi offers a softer, place-inspired sound.
A-initial names often carry meanings tied to morning, light, or color, which is why they fit the current preference for optimistic, visual names.
The pattern: A-initial names bridge the old kanji-meaning system and the new preference for short, image-forward choices.
What are the origins and structure of Japanese names?
Understanding one structural rule explains most of how Japanese names work.
Family name first, given name second
- In Japanese-language order, the surname comes before the personal name.
- This is why a name like “Sato Haruto” reads as family name Sato, given name Haruto.
Kanji readings and meanings
- Kanji have multiple readings, so the pronunciation of a name does not automatically reveal its meaning.
- The legal character set for names is protected by the Jinmeiyō list, helping keep official names readable.
Suffixes that shape meaning
- Boys’ names often use -to, -ki, and -ta; girls’ names often use -ko and -mi.
- Older suffixes like -hiko and -maru carry samurai-era weight.
- For a contrasting example of how different naming systems coexist, see this profile of Katseye members.
The implication: Japanese names are built from a small set of sonic patterns and a large map of meanings — which is why the same name can look different on a business card and a birth register.
What’s confirmed vs. unclear
Confirmed facts
- Minato and Sui topped Meiji Yasuda’s 2025 written-name rankings, as reported by Nippon.com’s Japan-data desk.
- Tamahiyo/Benesse’s 2025 survey placed Ao first for boys and Sui first for girls.
- Japanese names appear in surname-first order in Japan.
What’s unclear
- The total number of Japanese given names is unrecorded and likely uncountable.
- Ranking results differ by survey method and sample period, which is why one survey’s “number one” is not another’s.
- Future popularity trends are speculative, especially once new kanji enter the approved list.
Why it matters: Anyone quoting a single Japanese baby-name chart should be ready to explain which survey they used and why (The Japan Times, English-language daily).
Voices behind the data
“Japanese names are commonly written with kanji, and the same pronunciation can correspond to multiple kanji spellings with different meanings.”
— Nippon.com, Japan-data desk
“The kanji for Minato denotes a harbor, a place where water gathers, and was associated with hopes for sociability and many encounters.”
— Sankei Shimbun, national daily
“Tamahiyo’s 2025 ranking covered 83,839 boys and 82,172 girls born between January 1 and September 15.”
— The Japan Times, English-language daily
The takeaway
The shift from Haruto and Riko to Minato and Sui is not a blip; it’s a generational move toward shorter, nature-inspired names that still carry a wish in every syllable. For parents considering a Japanese name, the choice is no longer between traditional and modern — it’s about which natural image, color, or quiet hope you want attached to a child’s everyday life. For anyone reading a name on a roster, the lesson is simpler: the reading will not tell you the meaning, and the meaning will not tell you the reading. For parents in Japan, the choice is clear: pick a name whose sound and kanji work together in daily life, or you’ll spend decades explaining why they diverge.
Frequently asked questions
How do Japanese names work (order, kanji usage)?
Family names come first, given names second, and most names are written with kanji that carry meaning; hiragana and katakana are also allowed.
What is a yobisute (name suffix omission) in Japanese culture?
Yobisute means using someone’s name without a polite suffix like -san or -sama; it happens between friends, family, or in informal settings.
Why do Japanese names often end with -ko or -ta?
-ko appeared in many girls’ names for centuries; -ta became common in boys’ names. Both are now declining as parents choose shorter, more individual endings.
Can Japanese names be written in hiragana or katakana?
Yes. Hiragana is common for a soft, phonetic feel, and katakana is sometimes used for stylistic or international reasons.
Are there unisex Japanese names?
Yes. Names like Aoi, Rin, and Hikari can work for any gender; context and kanji choice usually settle the intended meaning.
How are Japanese names chosen (e.g., birth order, auspicious kanji)?
Parents often weigh the sound, the kanji’s meaning, how many strokes it takes to write, and how it balances with the surname. There is no strict birth-order rule, though some families keep naming patterns.
