Nestled on the most prime piece of shoreline, The Lake Suite Ko no Sumika offers a premium retreat designed to resonate with the breathtaking beauty of Lake Toya. Here, you can experience the tranquil morning calm as the lake's surface shimmers under the soft, clear light. The hotel features four distinct room types, each offering stunning lake views and a private open-air hot spring bath. The main public bath area presents a transcendent experience with its three-tiered, rice-terrace-style infinity pool. Cantilevered over the water, it creates a sensation of floating on the lake itself—a moment of pure bliss, as if relaxing in the sky. The heavens above put on a continuous show, changing colors with the seasons and time of day. On clear nights, guests can soak while gazing up at a natural planetarium of brilliant stars. The bathing facilities are further enhanced by a dry sauna offering panoramic views of Lake Toya. With the room temperature maintained between 90 and 95 degrees Celsius, it provides the perfect environment to relax while overlooking the timeless natural scenery. To complete the sauna experience, a cold plunge pool is available, maintained at a refreshing 10 to 12 degrees Celsius. This pool uses soft, pleasant-to-the-touch water sourced directly from the lake. For an added layer of rejuvenation, a jet bath cold plunge utilizes massaging bubbles from the floor. This not only helps cool down the body but also promotes fat decomposition for a toning effect. After your bath, retire to the After-Bath Living Terrace on the 8th floor. Here, you can soothe both body and mind while enjoying a cool beverage, bringing your serene lakeside retreat to a perfect close.
