Day 12
Crater lakes and Ainu land
Morning
Travel: 1 hr 30 min by car from Kitakobushi Shiretoko Hotel & Resort, 92.8 km
Lake Mashū
The lake occupies a closed caldera, with no inflow or outflow: its water is among the most transparent in the world, with visibility measured up to some forty metres. The 200-metre walls make it impossible to go down; you look at it from viewpoints 1 and 3. The Ainu called it the sea of the mountain gods, and mist swallows it for a good part of the summer.
Open access · Parking: ¥500 at viewpoint no. 1 (valid the same day at the Mount Iō car park), free at viewpoint no. 3
Afternoon
Travel: 26 min by car, 24.4 km
Lake Kussharo, Sunayu and Wakoto
On the shore of the country's largest crater lake, hot water wells up under the sand: at Sunayu, you only have to dig about ten centimetres into the sand to make yourself a hand or foot bath. The Wakoto peninsula, linked by an isthmus, adds a 2.5 km path and an open-air bath at the water's edge.
Open access · Sunayu: free parking · Wakoto: free open-air bath
Travel: 1 hr by car, 56.4 km
Lake Akan and Ainu Kotan
Lake Akan is known for its marimo, balls of green algae that roll slowly on the bottom, protected as a natural treasure. On the shore, Ainu Kotan is the largest Ainu village in Hokkaidō: some thirty families, wood-carving workshops and a theatre.
