Reviewed database tool
Japanese Name Checker
Check whether a complete kanji-and-reading pair appears in the site's current reviewed records. Results stay inside the publication gates instead of guessing whether an unseen name is real, natural, common, or suitable.

Exact-pair checker
Check a kanji and reading pair
153 reviewed pairs
Enter the full kanji spelling and its complete reading. Katakana is normalized to hiragana; romaji matching ignores letter case. Partial, fuzzy, and AI-inferred matches are never labeled as verified.

Evidence boundary
What a result does—and does not—establish
A reviewed match means
The exact written form and reading occur together in a record that passed required-field, source, review-date, and relationship checks. The result links to the full evidence record.
No match does not mean “invalid”
The database is limited. An unseen pair may exist outside the reviewed set. The checker does not infer naturalness, popularity, era, legality, baby-name suitability, or character-name suitability.
This result is uncertain whenever the complete pair is not found and should be treated as a search lead, not a verified real-world usage record.
How the checker works
- Step 1
Normalize the input
Spaces and letter case are normalized. Katakana readings are converted to hiragana for comparison.
- Step 2
Compare the complete pair
The checker requires the kanji and reading to belong to the same reviewed record. It never promotes a partial match.
- Step 3
Continue to evidence
Exact results link to the corresponding name or surname page for citations, usage notes, and related records.

Review the method and sources
The checker uses the same publication gates as the public entity pages. Review how records are selected, what each source can support, and how corrections are handled.
