Koshinetsu & Hokuriku
Nagano
Polycentric mountain prefecture: Nagano, Matsumoto, and ski-town economies.
Nagano City and Matsumoto are the main urban night poles; resort towns add seasonal leisure vocabularies that are not the same as adult entertainment districts. Olympics memory and alpine tourism shape the soft image. Districts writing should keep ski-resort nightlife speech from being flattened into kanrakugai.
Public names
Place-names that appear in news, comedy, and ordinary speech — not a list of venues.
