Where is Muramasa: The Demon Blade set?
2009 video game
Muramasa: The Demon Blade (2009) — 1 real place its Wikipedia article names as the setting, in Japan. Wikidata’s own statement stops at the country, so this is prose rather than a statement, and it is labelled that way below. Where the game takes place, not where it was made: a game is filmed nowhere, so this is the only kind of location it has.
