Hotel Lakeside Terrace Toyako Manseikaku is a hot spring hotel featuring an open-air bath with a breathtaking view that seems to merge with the lake, and a large bath where you can deeply experience both heat and cold. In the large bath, you can sharpen your senses with a 90°C löyly sauna and an approximately 11°C cold plunge bath flowing with the waters of Lake Toya. The water is a gentle sulfate and chloride spring that quietly absorbs the lingering heat. Time spent in the open-air bath, gazing at the starry sky and the lake surface, unravels your consciousness during the journey and deeply relaxes your mind.
