Day 12
Crater lakes and Ainu land
Morning
Travel: 1 hr 30 min by car from Kitakobushi Shiretoko Hotel & Resort, 92.8 km (57.7 mi)
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 40 meters (130 ft). The 200-meter (650 ft) walls make it impossible to go down, so you view 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 parking lot), free at viewpoint no. 3
Afternoon
Travel: 26 min by car, 24.4 km (15.2 mi)
Lake Kussharo, Sunayu and Wakoto
On the shore of the country's largest crater lake, hot water wells up under the sand. At Sunayu, dig about 10 cm (4 in) into the sand to make yourself a hand or foot bath. The Wakoto peninsula, linked by an isthmus, adds a 2.5 km (1.6 mi) 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 (35 mi)
Lake Akan and Ainu Kotan
Lake Akan is known for its marimo, balls of green algae that roll slowly along 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 theater.
