What this place is
Jōshin'etsu-kōgen National Park (上信越高原国立公園, Jōshin'etsu-kōgen Kokuritsu Kōen) is a national park in the Chūbu region of the main island of Honshū, Japan formed around several active and dormant volcanoes. It spans the mountainous areas of Gunma, Nagano, and Niigata prefectures. The name refers to the two mountain ranges that make up the park. It was divided into two separate areas: the Southern Niigata/North Nagano Area and the East Nagano Area.

Why it is worth the trip
- Panoramas that open up above the treeline — on clear days you can trace whole valleys and distant ranges.
- Vegetation that changes with altitude, from cedar forest to alpine flowers within a single climb.
- Ropeways, toll roads or mountain buses that put the scenery within reach of casual visitors, not just hikers.
What you can do here
- Ride the ropeway or mountain bus to the upper station and walk the easy loop trail at the top.
- Photograph the sea of clouds or sunrise — early morning is usually the clearest window.
- Hike a marked course matched to your time and fitness; most trailheads post an estimated round-trip time.
- Combine the visit with a nearby hot spring to finish the day.

Getting there by public transport
Good to know before you go
- Temperature drops roughly 0.6°C per 100 m of elevation — bring a windproof layer even in summer.
- Mountain transport stops early and pauses in winter or bad weather; check the last downhill service.
- Bring cash: summit shops and mountain huts often have no card readers or signal.
