Two Mamoru Hosoda films are built on places from his own life. Summer Wars is set in Ueda, Nagano; Wolf Children draws on Kamiichi, Hosoda's home town in Toyama, and the hills around it.
The route visits Ueda Station and the castle gate seen in Summer Wars, then Hitotsubashi University, a farmhouse in Kamiichi and a school in Namerikawa from Wolf Children. The Kamiichi pin marks the district, not the house.
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.
Sunja grows up in her mother's boarding house on Yeongdo, an island in the harbour of Busan, under Japanese rule. Pregnant by a married man, she marries a gentle minister instead and leaves with him for Osaka, where Koreans live poor and despised in a neighbourhood called Ikaino. The Apple TV+ series (2022–2024), based on Min Jin Lee's 2017 novel, follows four generations of her family from 1915 to 1989.
The route follows the family through real places in Korea and Japan, in story order. Homes, shops and offices in the series are fictional, so the pins mark the neighbourhoods and cities where the story is set, not filming locations.
