JMnedict classification evidence

How this reading is classified in the source corpus

This separates dictionary classification from popularity. The same exact kana reading can be recorded as a given name, a surname, or both, and given-name records can carry male, female or unspecified source labels.

Classification boundary: male/female/unspecified are labels attached to imported JMnedict name records. They are not population shares, probabilities, identity claims, or evidence that a spelling is currently common in Japan. A source row can also be repeated across different written forms, so row counts and distinct-writing counts are shown separately.

Reading ambiguity

Can the same writing be read another way?

30 of 80 displayed written forms have more than one given-name reading somewhere in the active JMnedict corpus. This is dictionary-record ambiguity, not a prediction of how a particular person reads the name.

A reading shown without a link is still source-recorded, but its destination group does not currently meet the canonical publication standard. Strong reference pages do not promote limited records merely to create extra internal links.

Kanji role reference

How recurring characters function across Kazuko spellings

Position counts are calculated only from the distinct written forms analyzed for this page. KANJIDIC2 nanori are character-level name-reading references; they are not used here to decompose or assert the reading of a specific multi-kanji name.

Counts describe this source-recorded spelling set, not population use. A repeated kanji can contribute to more than one position role across different spellings.

Exact writing research map

Move from a spelling to its readings, characters and literal sequence context

These relationships are exact and source-backed. Whole-name readings shown in each card come from JMnedict within the current name class; exact-writing search can surface records from other name classes. Character links open KANJIDIC2-backed kanji pages. Sequence context means the same kanji string occurs contiguously in another recorded written form—it does not prove shared origin or meaning.

What does Kazuko mean?

There is not necessarily one fixed English meaning. The reading identifies the spoken name; different written forms can use different kanji. Character glosses describe individual kanji and should not be treated as proof of the intention behind a particular person’s name.

Related readings

More names beginning with かず

Related by the opening kana of the dictionary reading. This is a deterministic browsing relationship, not a claim that the names share the same meaning.

What each source establishes

JMnedict establishes recorded written forms, readings and name classifications; where safely associated, this page can also show JMnedict-supplied trans_det source text without treating it as a whole-name meaning. KANJIDIC2 supplies character readings, nanori, stroke counts, grade classes and English character glosses. The Ministry of Justice remains the official reference for Japanese child-name character rules. The Agency for Cultural Affairs romanization guidance is the reference for generated Latin-script reading aids.
