Kussharo-ko

Top choice in Hokkaidō


Japan's largest caldera lake is a rich blue on sunny days. A small volcano peeks out from the centre, creating the island Naka-jima – best viewed from the Bihoro Pass.

The lake is also purportedly the home of a Loch Ness monster–-like creature nicknamed Kusshi.
