Method and limits

How to read our name records

Japanese Names is a structured reference and generation tool. It combines only stored surname records, given-name readings, and kanji variations. The standard generator uses local records; the optional AI-assisted tool interprets preferences and retrieves from the same records.

Source-recorded pairs

JMnedict documents a stored spelling-and-reading pair and the original name classification.

Dictionary-supported glosses

KANJIDIC2 supports character-level glosses without asserting one combined personal-name meaning.

Editorially reviewed context

Expanded entries add editorial explanations of written forms or surname context. These explanations are not a current usage survey.

What each source establishes

JMnedict

Supports the recorded kanji spelling, reading, and source classification. Each imported production record preserves its upstream entry ID.

KANJIDIC2

Supports individual character glosses. These glosses are shown as components, not as proof of a person's intended name meaning, popularity, style, or family history.

Source-backed dictionary records remain outside the sitemap until a detail page has enough editorial context to stand on its own. They can still support generator breadth because their spelling and reading are directly documented.

Editorial guidance and evidence

Editorial selection describes our browsing order, not a popularity ranking. Style, naturalness, and usage estimates are editorial guidance unless a specific supporting source is given. The general Jōyō Kanji table does not verify every personal-name reading, gender association, or frequency of use.

Dictionary glosses can include senses used in abbreviations or unrelated contexts. We keep those senses in character notes rather than joining them into an asserted name meaning. A spelling-and-reading record is evidence that a dictionary records the pair, not evidence of a particular person’s naming intention.

Display method updated September 9, 2026: separated general character glosses from name meanings and labeled editorial usage estimates.

What confidence labels mean

A literal kanji interpretation is not automatically an origin story. We separately label well-documented material, common interpretations, multiple possible origins, literal-only readings, and uncertainty. No label implies that every person with the same surname shares one ancestor.

Reference starting points

These references establish recorded name pairs, character glosses, system history, research method, or standard character readings. Individual surname histories need additional surname-specific sources before deeper claims are added.
