Where is Bocchi the Rock! set?
Japanese manga series
Bocchi the Rock! (2019): 2 real places Japanese Wikipedia files it under as its setting, in Japan. Wikidata records no setting for this manga at all, so this is a category rather than a statement, and it is labelled that way below. Where the manga takes place, not where it was made: a manga is drawn and filmed nowhere, so this is the only kind of location it has.
Part of the Bocchi the Rock! franchise
