Welcome to Towada-ko
Hemmed in by rocky shores and dense forests, sparkling Towada-ko (十和田湖) is the largest crater lake in Honshū (52km in circumference) and a fabulous natural attraction for those seeking solitude. Towada-Hachimantai National Park once bore witness to a series of violent volcanic eruptions; today the only action is the quiet trickle of the Oirase Keiryū mountain stream, winding its way to the Pacific Ocean. The main tourist hub, Yasumiya, is a small village with a lovely waterfront promenade. The other lakeside village, Nenokuchi, is little more than a transport hub.
