Realistic Japanese Character Name Checker

“Realistic” is not one automatic score. This checker separates what the reviewed database can establish—the exact family-name and given-name components—from the full-name combination and story context that still require research.

Evidence index: 50 surnames + 187 given-name variants · Updated 2026-07-30

Exact-component research tool

Check a fictional character's full name

Compare the family name and given name separately against 50 reviewed surnames and 187 reviewed given-name variants. The result reports evidence gaps without inventing a realism percentage.

Interpretation boundary

Read the three statuses separately

Status 1

Component evidence

The family and given names are checked separately against 50 reviewed surnames and 187 reviewed given-name variants.

Status 2

Combination boundary

Two reviewed components do not prove that the combined full name is attested, common, or natural as one real person’s name.

Status 3

Context review

Birth period, region, family background, social role, language environment, name order, and forms of address remain story-specific research questions.

What the checker does

  1. Normalizes spaces, letter case, and katakana readings without changing the submitted kanji.
  2. Requires each kanji spelling and reading to occur together in the same reviewed component record.
  3. Labels spelling-only or reading-only records as reference candidates, never exact matches.
  4. Reports that the complete family-plus-given combination is not independently attested by this component database.
  5. Produces context-specific review questions instead of an unsupported realism percentage.

What the checker cannot certify

  • Whether a full combination belongs to a real person
  • Historical or regional plausibility
  • Generational frequency or class association
  • Legal registration of a proposed name
  • Natural dialogue, honorifics, or forms of address
  • A character's identity or cultural authenticity
  • A bearer's intended kanji meaning
  • Suitability for publication without human review
