Shikotsu-Tōya National ParkShikotsu-Tōya National Park is a protected area in southwestern Hokkaido that encompasses two prominent caldera lakes and several active volcanoes. The park is known for its volcanic landscapes, clear crater lakes and geothermal activity.
Major visitor attractions include Lake Shikotsu, noted for clear water and mountain-ringed shores, and Lake Tōya, a near-circular caldera lake containing wooded islands and a lakeside resort area with hot springs. The park also features volcanic peaks such as Mount Usu and Mount Tarumae with hiking trails and ropeways.
Volcanic activity has repeatedly reshaped the area in recent centuries; eruptions of Mount Usu in the late 20th and early 21st centuries altered access routes and viewpoints and contributed to the park’s ongoing geological interest. Thermal activity supports hot spring resorts and geological interpretation sites.
The park lies in southwestern Hokkaido, with access from regional centres such as Sapporo by road and rail. Lakeside towns around Lake Tōya and Lake Shikotsu act as visitor bases for hiking, boating and onsen stays.

How to Get to Shikotsu-Tōya National Park#
Shikotsu‑Tōya National Park covers areas around Lake Shikotsu (near Chitose) and Lake Tōya (Toyako Onsen). From Sapporo you can drive to the park areas or use regular highway buses that run to Toyako Onsen and to access points near Lake Shikotsu; driving time from central Sapporo to the main lake areas is typically around 1-1.5 hours depending on destination and traffic. Once at Toyako Onsen or the Lake Shikotsu visitor areas follow local signs and trails to reach lakeside viewpoints.
Tips for Visiting Shikotsu-Tōya National Park#
- For calm, reflective views of the lakes and fewer crowds, plan early-morning visits to Lake Toya and Lake Shikotsu; volcanic steam and clouds can build up later in the day and reduce visibility.
- Use the town on the lake you plan to explore as your base-Toyako Onsen gives easy access to the lakefront and Usu Ropeway for panoramic views, while Chitose provides the best access to Shikotsu.
- Take the Mt. Usu ropeway to the summit viewing platforms for a quick, low‑effort panorama of Toya Caldera and the lakes-many visitors stick to the shoreline and miss this vantage point.
- If you want to hike, pick trails on clear-weather days and check local park information for volcanic activity notices; some crater viewpoints are closed intermittently for safety.
