Dip a toe in the waters of Kanro-sui. Weather permitting, you can go for a splash around or just sit back and enjoy spotting wildlife.
When you've finished exploring this Niseko waterhole, why not make your way to Niseko Mountain Resort Grand Hirafu, Niseko Village, and Niseko Annupuri International Ski Area? They're close to Kanro-sui and also popular with many tourists.
