Shiga Omihachiman City
A soothing retreat of radium onsen and true sauna, wrapped in the Lake Biwa breeze and the scent of burning wood
Chomeiji Onsen Amaha no Yu is a day-trip bathhouse standing on the shore of Lake Biwa in Omihachiman, Shiga Prefecture. Its biggest draws are a natural radium onsen with the greatest flow in Shiga Prefecture and a true wood-fired sauna with a stove made in Finland, the home of the sauna. After a long, slow sweat wrapped in the crackle and scent of burning wood, you cool your whole body in the deep cold plunge. Cooling off in the open air in the outdoor area, with the breeze off Lake Biwa, brings a rare sense of ease that makes you forget the fatigue of daily life. After bathing, you can spend as much quiet, unhurried time as you like on the terrace overlooking the lake or in the hall with its reclining chairs.

A natural radium onsen with the highest radon content in Shiga Prefecture. Its soft, gentle feel on the skin is its hallmark, and it slowly warms you to the core. Making your way around the varied baths, such as the Shigaraki-ware ceramic urn bath and the hinoki bath in the open-air area, you can enjoy deep relaxation in the clear air of the Lake Biwa shore.

A true wood-fired sauna with a stove made by NARVI of Finland, the home of the sauna. Wrapped in the crackle of burning logs and the rich scent of wood, the room is deeply immersive, a place to quietly turn inward. The soft yet powerful heat that only wood can give envelops the whole body and slowly draws a pleasant sweat from the core.

A low-temperature sauna with a calm, Japanese-style tatami interior. Even if you find heat hard to bear, you can stay for a long, slow session without feeling stifled. Warming your body slowly in the stillness, you can spend a gentle, relaxing time as the tension in body and mind eases away.

A deep, serious cold plunge right beside the sauna. Plenty of cold water cools the flushed body at once, while a pleasant current stimulates the whole body. After the cold plunge, you can move smoothly on to cooling off in the open air in the outdoor area swept by the Lake Biwa breeze, for a superb sense of refreshment.
