Lake Tazawa, the deepest lake in Japan, is adorned with a Persian blue surface and the legend of Princess Tatsuko. Located on the lakeside, Lake Tazawa Rest House offers a lake-view restaurant and shopping for Akita specialties. The courtyard offers a spectacular view of Lake Tazawa, and the beautiful, wide green lawn makes it a popular place to relax. Furthermore, the house is also the departure and arrival point for buses that circle Lake Tazawa, connecting to Nyuto, Tamagawa, Hachimantai, and the Komagatake trailhead, as well as for sightseeing boats on Lake Tazawa, making it a perfect base for sightseeing around the lake.
