Nagano Snow Monkeys & Zenkoji Guide 2026
Eighty minutes from Tokyo by bullet train: wild snow monkeys bathing at Jigokudani (¥800), the 1,400-year Zenkoji and its pitch-black under-altar passage, Shibu Onsen and Obuse.

The Jinnouchi family estate and the summer-countryside stage of Mamoru Hosoda’s Summer Wars are modeled on Ueda, Nagano. Unusually, the city’s official tourism-association microsite is remarkably explicit — it calls Ueda “the ideal countryside that became the stage for the movie Summer Wars,” and lays out the correspondences: the east-gate turret of Ueda Castle as the model for the Jinnouchi gate, Sanada Shrine where a “box-office hit prayer” was held for the film, and the Bessho Line as the real-world basis for the train to the fictional hot spring. The city even offers a pilgrimage stamp notebook with a cover drawn by Hosoda himself, a sign of sustained, willing cooperation. And at about 90 minutes by Shinkansen from Tokyo, it’s a realistic long day-trip pilgrimage.
| ✔ | Spot | Area | Scene & guide | Access |
|---|---|---|---|---|
| 上田城跡公園 東虎口櫓門 | 上田市 | The official “Summer Wars, Shinshu Ueda” location guide states that the east-gate turret (Higashi-Koguchi Yaguramon) of the Ueda Castle ruins was the model for the gate of the Jinnouchi family residence. As the symbol of the protagonist’s household, it’s the central stop of the route. | JR・信濃鐵道 上田站徒步至上田城跡公園(依官方頁,未載明確分鐘數) | |
| 真田神社 | 上田市 | Per the official guide: this shrine tied to the Sanada clan held a “hit prayer” for the film ahead of release, which the page credits with contributing to its box-office success. It sits inside Ueda Castle Park, right by the turret gate. | 上田城跡公園內 | |
| 上田電鉄別所線(まるまるどりーむ号) | 上田市 | Per the official guide: the film’s train toward a fictional hot spring is modeled on the real Bessho Line, which actually terminates at Bessho Onsen; the guide singles out the “Marumaru Dream” liveried train as a fan favorite that appears in the film. Ride this line to recreate the movie’s rail scenes. | 上田站 別所線月台 | |
| 上田市役所 | 上田市 | Per the official guide: the background of a scene where a character operates her avatar by mobile phone is drawn from Ueda City Hall. It’s near Ueda Station and easy to pass by. | 上田站附近 | |
| 上田市観光会館(観光案内所) | 上田市 | Per the official guide: this center holds a pilgrimage stamp notebook whose cover was illustrated by director Mamoru Hosoda himself. Right by Ueda Station, it’s a natural first stop to pick up information and start stamping. | 上田站旁 |

The official “Summer Wars, Shinshu Ueda” page states it plainly: “90 minutes from Tokyo by Shinkansen” — about 90 minutes on the Hokuriku Shinkansen, direct to Ueda Station with no transfer. That makes Ueda a realistic long day-trip from Tokyo (source data marks it dayTripFromTokyo: true). Suggested flow: from Ueda Station stop at the adjacent tourist center for the stamp notebook, walk into Ueda Castle Park for the turret gate and Sanada Shrine, pass City Hall on the way back, and leave time to ride a stretch of the Bessho Line to recreate the rail scenes.
A pilgrimage run means walking with one hand holding your phone up against an anime screenshot the whole day — that eats data fast. Grab a KKday Japan eSIM before you land so you are not hunting for Wi-Fi at every filming spot.
