There’s an anime called ZatsuTabi, where every episode has the main character go somewhere different, and every place is a real place. It almost feels like cheating.
I would also suggest Syowa Station in antarctica, visited in A Place Further Than the Universe. It’s already listed with Singapore, but the station is a real place too.
Edit: Oh! Also, A Salad Bowl of Eccentrics is set in Gifu.
Yay! This is gonna be so peak.
