Population and area by municipality, from Wikidata under CC0, joined to postal codes through the dantai code. GeoNames romanises Japanese place names and Japan's own statistics are keyed in kanji, so the join is by name within a prefecture rather than by a shared identifier. Figures describe the whole municipality, not the postal code.
