30 Japanese Names: Kanji, Readings, and JavaScript Data

A careful reference to 30 Japanese given-name spellings, with kanji and kana kept distinct, character-level glosses, and a practical JavaScript schema.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Japanese given names do not have one fixed spelling: the same sound can be written with different kanji, and a kanji spelling may have more than one reading. The 30 records below keep romanization, exact kanji, kana reading, and literal character gloss separate. A gloss describes the characters; it does not establish why a family chose a name or give a definitive meaning for the name as a whole.

How to read the name list

The 12 records marked “Benesse 2025 sample” use spellings shown in Benesse’s 2025 girls’ or boys’ ranking. They are examples from names submitted through Benesse products and services—not a census or a complete mapping of each reading to all possible spellings. The other 18 are illustrative entries from a secondary directory, not verified ranking entries. Their glosses below are deliberately literal character-level aids rather than the directory’s more poetic interpretations.

Benesse reports 166,011 submitted names for babies born January 1 through September 15, 2025: 83,839 boys and 82,172 girls. Treat those figures as the scope of that survey sample, not as national birth statistics. Gender labels below are limited to the category in which Benesse lists the sample entry; no gender label is inferred for illustrative records.

What kanji glosses can—and cannot—tell you

A gloss gives a compact sense of an individual character, not a translation of the whole name. For instance, the characters in 陽翔 can be glossed as “sun” and “soar,” but those pieces do not prove that the name was intended to mean a particular phrase. Families may choose a spelling for sound, associations, family preferences, or other reasons that a character dictionary cannot establish.

Elebase USB to USB C Adapter for iPhone 18 Pro Max,USBC Car Charger Adapter
  • Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
  • Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
  • Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
  • Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

Names also demonstrate why the exact writing matters. Hinata appears here with 陽葵 and 日向, and Ren with 蓮 and 漣. Those spellings have different character glosses even though the listed reading is the same. Keep each spelling as a distinct record rather than treating romanization as a unique identifier.

Character eligibility is not the same as reading approval

Japan’s Ministry of Justice identifies the Jōyō kanji and Jinmeiyō kanji tables as character categories usable in children’s names. Its page is guidance about eligible characters, not a ranking, a dictionary of intended name meanings, or proof that every possible reading of a character combination is common or will be accepted for a particular name. Check the Ministry’s current information at 子の名に使える漢字 when evaluating a proposed name.

Unicode’s Unihan database is useful for character-level reference data, but it likewise does not establish the intended meaning of a complete personal name. Its version 34 report records 863 ideographs in the Jinmeiyō table. Use character references as aids, and verify the reading and legal requirements separately.

Represent names as separate fields in JavaScript

Preserve the original romanized form, kanji, kana, gloss, and evidence label as separate fields. If a spelling is not established for a given reading, do not generate one from the romanization. The gloss is only a character-level aid, and the reading may need independent verification.

Use all fields when displaying or matching records. A search by romanization alone may return multiple spellings; retaining both kanji and kana avoids silently merging distinct entries.

Counting Japanese name characters in JavaScript

JavaScript’s String.length counts UTF-16 code units, which is not a universal count of visible characters. For example, a displayed character can in some cases consist of more than one code unit. MDN documents Intl.Segmenter for locale-sensitive segmentation; its grapheme mode can count user-perceived character clusters:
