Kamuiwakka Hot Falls
A hot-spring river on the Shiretoko Peninsula, dropping in steps over bare volcanic rock at the end of a gravel park road. The lowest fall is free to stand and look at. Climbing any higher is booked, charged and seasonal.

The sweet spot
This is one of the eight designated views of Shiretoko, so it is not a hidden place. What thins the numbers is the road. It is open for only part of the year, it shuts inside the season when a bear is working the area, and on the busiest August days nothing but the shuttle is allowed past the gate.
Where it is
102 more notes in Hokkaido · open the map →What to look for — in walking order
- The end of the park roada gravel pull-in with a management hut and a gate across the road
- The first fallthe lowest step, a few minutes up from where the cars stop
- The warm streambedbare rock stained by sulphur, the water growing warmer upstream
- The third fallthe steepest step on the booked route, and the usual turning point
- Mount Iothe active volcano upstream that makes this water hot and sour
How to actually get there
- Shiretoko-Shari Station → Shiretoko Nature Center (Sharibus Shiretoko line, by way of Utoro Onsen).
- Nature Center → hire water shoes, and on shuttle days board the Kamuiwakka bus.
- Kamuiwakka pull-in → change footwear and walk up to the first fall.
- With a booking, carry on up the streambed as far as the fourth fall, then turn back.
- Shuttle or your own car from the Shiretoko Nature Center
- The Nature Center is the changeover point for everything up here. On the peak August days, when private vehicles are barred above the Five Lakes gate, a shuttle runs from the Center to Kamuiwakka and the Ministry of the Environment allows about forty minutes for the ride. For the rest of the open season you drive the same road yourself. Reaching the Center from Shiretoko-Shari Station means the Sharibus Shiretoko line by way of Utoro Onsen.
- Return from the Kamuiwakka pull-in
- There is no scheduled bus off the falls outside the shuttle days, so you leave the way you came. On shuttle days, read the last departure off the pole at the pull-in before you change into your shoes. The park road is long, unlit, and on regulated days closed to people on foot and on bicycles as well as in cars.
About the place
Kamuiwakka is not a cold stream. It drains Mount Io, an active volcano near the middle of the peninsula, and what runs down the rock is hot-spring water of about pH 1.6 — acidic enough to sting a cut and to keep fish out of the river altogether. The Ainu name says so plainly: kamuy, a god or a power beyond people, and wakka, water. The falls are not a single drop but a staircase of them, cut into bare rock the sulphur has stained yellow and grey. The lowest step stands a few minutes above the point where the road gives up.
How to enjoy it
The climbing season published by the operator runs from the start of July to the end of September, and slots are sold online only — nothing at all is sold at the stream. Water shoes are hired at the Shiretoko Nature Center on the way in, so settle that before you drive up. Allow most of a morning, because the wading itself is the short part.
Background & history
Mount Io has a strange and violent record. In 1936 it poured molten sulphur and boiling water down this very river to the sea, an eruption style found almost nowhere else on earth. The peninsula was inscribed as a UNESCO World Natural Heritage site in 2005, and it was that listing, and the crowds behind it, that closed the upper falls to the public. They stayed shut for the better part of two decades before reopening in 2023 — no longer free, and no longer unsupervised.
Before you go
- Cash
- Standing at the lowest fall costs nothing. Going above it does not: slots are sold online in advance, the price is set per season, and the helmet comes with it. Water-shoe hire is charged separately and handled at the Nature Center. There is no desk, no shop and no vending machine at the falls, so arrive with the booking already made.
- Before you go
- The park road above the Five Lakes gate shuts for winter, closing in autumn and reopening in early summer, and the Okhotsk regional office issues the actual dates each year. It also closes mid-season without notice — in 2026 the town shut the road while it dealt with a problem brown bear near the falls. On the peak August days only the shuttle passes the gate.
- Another way
- By car the approach is the Shiretoko park road past Utoro Onsen, the Nature Center and the Five Lakes gate, with the last stretch on gravel. From the water, sightseeing boats out of Utoro run up this coast to a different waterfall also called Kamuiwakka, which drops straight into the Sea of Okhotsk downstream of this one and cannot be climbed.
- After you get off
- Cars and the shuttle both stop at a gravel pull-in beside the Kamuiwakka bridge, marked by the bus pole and a small management hut. The first fall is a few minutes upstream from there. Change footwear at the pull-in, because past the gate you are walking in the river rather than beside it.
