Rusutsu is a smaller resort with two large hotels, one of which has a Vegas-style Bavarian village in the lobby and a roller-coaster (not operational in the winter)!
The skiing is on two entirely separate mountain areas, one chiefly for beginners. The second includes masses of rolling cruisers as well as some steeper tree skiing. There are impressive views of the surrounding volcanic landscape dotted with blue lakes.
Rusutsu is an hour’s drive from Niseko, making it easy to visit on a day trip from Niseko.
