Sansui Lakeside Villa  

On the shores of Japan’s largest caldera lake in Teshikaga, inside a national park and about 18 km from the town center. This lakeside villa pairs hot spring scenery with sweeping mountain-ridge views.

Eco-friendly suites run on solar and geothermal power within a highly insulated building. Each unit has a private kitchen and true privacy—no staff unless requested. Private open-air hot springs sit on the deck and appear to spill toward the lake. The lake is right at your door for swimming, fishing, canoeing, or stand-up paddling.

Private on-deck open-air onsen. Direct lake access and gear-friendly shoreline for water sports. On-site restaurant, free parking, and optional transfer service. Sustainable comforts throughout—solar power, geothermal heating, and top thermal insulation. Wake to misty lake mornings and panoramic water views.

Stop by the on-site restaurant or use your private kitchen to self-cater. Easy options for relaxed, lakeside meals.
