An uninhabited island rich in nature, floating in the middle of Lake Toya. You can reach it by sightseeing boat, and the island is covered in old-growth forest with well-maintained hiking trails. Viewing Nakajima from the lake and looking back at the lakeshore from the island each have their own charm.

Rising on the south side of Lake Toya, Mt. Usu is an active volcano that is still active today. A ropeway takes you to the summit, where you can take in sweeping views of the lake and its surroundings. Showa-Shinzan, born in an eruption in 1944, is a relatively young volcano that still emits plumes of smoke — a rare spot where you can see a volcano’s growth up close.

📍 About 15 minutes by car from Toyako Onsen town (Mt. Usu Ropeway)

On Lake Toya’s calm waters, exploring the lake by boat or canoe is a popular activity. The clear water and beautiful views of the surrounding mountains and islands make for a relaxing time. A cycling course also runs along the lakeshore, so you can enjoy nature while circling the entire lake.

A fireworks festival held every night for about half the year, from spring to autumn. For about 20 minutes, fireworks light up the lake, and both overnight guests and day-trippers can watch from the lakeshore. This long-running format is rare even in Japan, so you can catch the fireworks whenever you visit.
