Where is The Anthem of the Heart set?
2015 animated film directed by Tatsuyuki Nagai
The Anthem of the Heart (2015): 1 real place its Wikipedia article names as the setting, in Japan.

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.
