This service is available at Lake Shikotsu, which is the northernmost ice-free lake and one of the clearest and deepest lakes in Japan. From the sightseeing boat, you can enjoy the contrast of the cobalt blue lake with the surrounding mountains and greenery. One of the popular boats is the underwater sightseeing boat, with windows positioned 2 meters below the surface of the lake, from which you can view the rough rocks and sand ripple at the bottom of the lake. The company also operates a high speed boat for those who love speed, a large sightseeing boat holding up to 200 passengers, and pedal boats for slower-paced sightseeing.
