Insider tip — Ipponkizawa Onsen, the single tree stream spring, serves Towada City — the gateway to Lake Towada, the ancient volcanic caldera lake at 327 metres depth that straddles the Akita-Aomori border. The sacred Towada caldera was formed by a cataclysmic eruption over 13,000 years ago and the lake's extraordinary water clarity and the surrounding virgin beech forest make it one of Japan most pristine alpine sanctuaries.
