Where is Pokémon Ranger and the Temple of the Sea set?

2006 anime film directed by Kunihiko Yuyama

Pokémon Ranger and the Temple of the Sea (2006) 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.
