The anime Hyouka is set in a fictional town, but its backdrops are real streets in Takayama, in the mountains of Gifu. The author's home town became the model, and the local tourism board publishes an official pilgrimage model course.
This route follows six places from the opening title to the final episode: the river and morning market, the school-route crossing, the Old Town, the library, the hill shrine and the festival shrine outside town. Where the story renames a place, the pin marks the real one.
Taki, a Tokyo schoolboy who waits tables in Shinjuku, keeps waking up in the body of Mitsuha, a shrine maiden in a mountain town who has never left it. They leave notes on each other's skin, fall for each other from a distance — and then the switching stops dead. Taki rides west with two friends to find the town he can only draw from memory, and finds it gone: a fragment of a comet took Itomori and five hundred people three years before his visit.
The town was invented, but the film stands on real ground: the Shinjuku where Taki lives and works, the Hida valley that lent Itomori its backdrop, the lake generally credited with the crater pool, and the stone staircase where the story ends. One caveat: Itomori was never filmed, so its crater is the one stop here without a pin.
