Shikoku
Ehime
Matsuyama’s Dogo onsen brand beside a separate city night layer.
Matsuyama pairs one of Japan’s most famous onsen names (Dogo) with an ordinary regional-capital entertainment layer. Imabari and other cities add smaller footprints. Again: onsen hospitality vocabulary ≠ kanrakugai map.
Public names
Place-names that appear in news, comedy, and ordinary speech — not a list of venues.
