Shikotsu-Tōya National Park is a national park in the western part of the island of Hokkaidō, Japan. Named after the volcanic caldera lakes of Lake Shikotsu and Lake Tōya, it has a total area of 993.02 square kilometres (383.41 sq mi). The popular hot spring resorts of Noboribetsu, south of the lake, and Jozankei, north of the lake, are also within the park.

Insider tip — Lake Toya Hot Spring lines the southern shore of the caldera lake formed by the Shikotsu-Toya volcanic system, with large resort hotels offering panoramic views across the water to Mount Yotei. The sodium-chloride waters warm the body deeply and are renowned for their moisturizing effect on skin. Summer evenings bring spectacular fireworks displays reflected on the calm lake surface, visible from the hotel rotenburo. The nearby Mount Usu, which last erupted in 2000, offers fascinating lava field walks that put the thermal geology powerfully in context.
