Includes Japanese prefectures from Codexery codexes where at least 70% of entries are sourced and carry this field; an entry is listed only when the value shown appears in its own cited source article. Entries without a verifiable population are left out rather than estimated. Values are copied from structured data already on each Codexery page and re-checked against the linked source; nothing on this page is estimated or written by a model. Spot an error?
