2012 film by Tatsuya Nagamine

One Piece Film: Z (2012) is not pinned on this map. Wikidata records no setting for this anime. What is below is the weaker claim its Japanese Wikipedia article makes: the real places its setting was modelled on. Where the anime takes place, not where it was made: an anime is drawn and filmed nowhere, so this is the only kind of location it has.
