Ogihara — Japanese given-name survey (OSF), 2024 on the left; every record we hold for Japan on the right. A dashed line means the name is not in our top ranks for this country at all.

The register counts one population in one year — everyone it enumerates, once. Our corpus counts records: historical registers going back decades, the diaspora, business and place records, and several generations of births. A name that was common two generations ago outranks a name common today; a name whose spelling scatters across sources (diacritics dropped, transliterated differently) loses ground, because only its dominant spelling is ranked.

Characteristic of Japan

Not the most common names — the most distinctive ones. A name appears here when Japan holds a larger share of its bearers than the world does, weighted by how much of the country's whole name distribution it accounts for.

Over time

Ogihara — Japanese given-name survey (OSF), 20042024 (21 years). The line is that register's own figure for each year — not a total across registers, which would count the same people twice. The publisher labels this series “flow”.

Up to five names at a time.

Scripts & spelling

Names in Japan are written in Latin (67%), Han (23%) and Japanese (10%), measured over the spellings our corpus records for this country.

The best-attested names in Japan, in the spelling our records use there. Where a Latin spelling is also attested it is shown beneath — a spelling from the corpus, not a machine romanisation.

Countries whose names look alike

Measured as the overlap between each country's top 300 given-name forms, weighted by how common each is — the fuzzy-set approach of Lauc (2024), on a truncated inventory.

About this data

Official figures are reproduced from the register named beside them, at the year named beside them, and are never combined across registers. The "across all records" ranking counts records in our own corpus — historical registers, the diaspora, business and place records — and is not a population count. Bearer estimates are omitted where a name accounts for more than a quarter of a country's records, because the estimate is not defensible there. Names listed by reference works and licensed name dictionaries are cited as attesting a name; their figures are not published.
