Kamikochi

Chubu, Japan · Mountain

A valley in the Japan Alps closed to private cars: you arrive by bus or taxi and walk the bank of the Azusa as far as Kappabashi bridge, with the Hotaka massif straight ahead. A Shinto ceremony on the bridge itself opens the season in late April, June starts the serious climbing towards Yarigatake, and in late September the Karasawa glacial cirque turns red. Once the last bus has gone, the valley empties out.

Frequently asked questions about Kamikochi

What to do in Kamikochi: 24 activities

• Kappabashi Bridge and the Azusa River 1 h must-see

  An iconic bridge over crystal-clear waters, with the Hotaka mountain range in the background.

• A night at Karasawa Hyutte 14 h booking only 27 Apr - 3 Nov

  In 2026 it runs from 27 April to 3 November, closed 11-31 May for building work, and booking is compulsory with no walk-ins: ¥16,000 with dinner and breakfast, ¥14,000 with dinner only, ¥13,000 with breakfast only and ¥11,000 with no meals, ¥3,000 less up to primary-school age and no beds at all for under-threes. Book online and you pay by pre-registered card; book by phone and you pay up at the hut. The tent field works the other way round: no reservations, first come first served.

• Sleeping inside the valley 14 h booking

  Once the last bus goes, the valley empties: staying the night, whether in the 1933 imperial hotel or a simple hut, is what separates a visit from an experience.

• Up the Yarisawa valley to Yarigatake Sanso 12 h booking only 1 Jul - 31 Oct

  Two or three days from Kamikochi: the first along the flat valley to Yarisawa Lodge, the second up the Yarisawa itself, a funnel of grass and stone, to Yarigatake Sanso, the hut pitched just over 3,000 m at the foot of the spire. Nagano Prefecture grades the full ascent of Yarigatake, summit included (3,180 m), at 39.1 km, 20 hours of walking and 2,130 m of cumulative ascent round trip, technical grade C: those figures are for the whole route, and the walking part ends at the hut, because the last hundred metres of equipped rock to the top are a different sport. The hut, the col and sunrise over the valley are all reached on a marked trail.

• Walking up to Karasawa, the Hotaka cirque 11 h booking only 1 Jul - 31 Oct

  You leave Kamikochi (1,505 m) along the flat valley floor through Tokusawa and Yokoo, and the real climbing starts at Hontani bridge: the Karasawa glacial cirque at roughly 2,300 m, with two huts and a tent field. Nagano Prefecture's official route grading gives the round trip 30.6 km, 11.3 hours of walking and 1,170 m of cumulative ascent, at technical grade B — a marked trail with steep sections. Almost nobody does it in a day; the normal plan is two days with a night at Karasawa Hyutte.

• Dawn mist and a starry sky 2 h

  Only those who sleep inside see it: the mist rising off Taisho Pond at daybreak and, the night before, a starry sky with no light pollution at all.

• Hiking to Myojin Pond 3 h

  A flat trail along the river to a sacred pond surrounded by forest.

• Oku-Hotaka from Karasawa: where the walking stops 2 h only 1 Jul - 31 Oct

  Oku-Hotaka (3,190 m) is Japan's third-highest summit and you see all of it from the cirque, but the walkers' trail ends at Karasawa, around 2,300 m: the route to the col and the top follows the Zaiten-iwa spur, which Nagano Prefecture grades technical C — rock, loose scree and equipped sections where you need your hands — and totals 36.6 km, 17.7 hours and 2,080 m of ascent round trip from Kamikochi. If you walk eight hours with a pack but don't scramble, you stop here and spend the afternoon looking at the wall. Kita-Hotaka, graded D, is further out of reach still.

• Taisho Pond 1 h

  A pond with submerged dead tree trunks and the Hotaka mountain range in the background.

• The clock inside a Japanese high-mountain hut 14 h booking

  A yamagoya is not a mountain hotel: dinner at five, lights out at eight, everyone up at four to walk in daylight, and you sleep on a futon on a shared platform with no shower and water strictly rationed. Bookings for the Yari huts open exactly one month ahead at nine in the morning and in August they are gone the same day; over in the Hakuba valley, the town hall says every hut takes advance reservations only. Knowing this before you book is what tells you whether the route is for you.

• A night at Yarisawa Lodge 13 h booking only 27 Apr - 3 Nov

  This is the approach day that makes Yari possible: the lodge sits where the valley starts to tilt upwards, and in 2026 it opens 27 April to 3 November, the same dates as Yarigatake Sanso. It costs ¥16,000 with dinner and breakfast, ¥17,500 with a packed lunch as well, ¥14,500 with dinner only, ¥12,700 with breakfast only and ¥11,200 with no meals (the ¥200 lodging tax included), with ¥8,000 off up to primary-school age and ¥5,000 off for secondary and high-school students.

• Climbing Mount Yakedake 6 h

  An active volcano with visible fumaroles, whose ascent route from Kamikochi offers the best panoramic views of the valley.

• Grilled trout at the Kamonji hut 1 h

  Beside Myojin Pond, a hut running since 1880 skewers iwana trout around the fire and grills them slowly with salt.

• Guided walks with a naturalist 2 h booking

  The visitor centre organises short outings with guides who explain the geology of the valley and its wildlife; there are options in English.

• Hot springs at 1,500 metres 1.5 h

  There are indeed onsen inside the valley and at the tunnel entrance: real mountain baths after a long day of walking.

• Karasawa glacial cirque in autumn 10 h booking

  In late September the glacial amphitheatre fills with red and yellow; it is among the most spectacular autumn colour in Japan, but it means sleeping up there.

• Tokusawa and Yokoo, gateway to the high mountains 8 h

  From the head of the valley the serious routes towards Hotakadake and Yarigatake begin, the great climbs of the Japan Alps; they require a night in a mountain hut and real experience.

• Wildlife of the valley 1.5 h

  Japanese macaques, the elusive serow and dozens of birds are easily seen from the trails themselves along the Azusa river; keep your distance and do not feed them.

• Camping at Konashidaira or Tokusawa 14 h booking

  Two campsites inside the park, the cheapest way to stay the night in the valley; there is gear rental at the Konashidaira site.

• Dakesawa Viewpoint 2.5 h

  A steeper trail offering close-up views of Hotaka's rocky spires.

• Hotaka Jinja Okumiya Shrine 0.5 h

  A small Shinto shrine on the shores of Myojin Pond, dedicated to the Hotaka mountains and host to a boat festival in October.

• Tokusawa Meadow 4 h

  A wide grassy clearing along the Azusa River, about a two-hour walk from Myojin Pond, popular among hikers heading to the Hotaka Alps.

• Valley opening ceremony 1.5 h only 27 Apr

  Every April 27 the Shinto ceremony that officially opens the mountain season is held on Kappabashi bridge.

• Weston Festival 2 h only early June

  Annual ceremony held in early June marking the opening of the mountain season and honoring Walter Weston, who introduced the Japanese Alps to the West.
