NextGood to know
Choosing a campground in Tsumagoi

A lake, a forest, or the high meadow

Tsumagoi's campgrounds sit by a lake, in the forest or on the open plateau, and each makes for a different day. This one is a meadow at 1,444m.

By a lake
Fishing, kayaks and the water's edge fill the day.
In the forest
Shade and the sound of a stream; a cool place out of the summer sun.
The high meadow (here)
Wide views, clear-night skies, one free field with no numbered pitches (5 groups a night), and the Kotatsu Lounge with fibre desks. It is open grassland, not a shaded forest site.

It suits you if you want to

  • want a warm base on cold nights (the Kotatsu Lounge is open 24 hours; remote work OK)
  • bring your pet (allowed across the field)
  • camp or car-stay in winter too
  • stay in your car instead of a tent

Good to know first

  • There is no onsen on site. Manza Onsen is about 10 minutes by car (about 15 in winter).
  • No power at each pitch: two paid power points at the pump room.
