Saitama Hanno City
A superb setting and supreme relaxation to your heart’s content
Miyazawako Onsen Kirari Bettei is a day-use onsen bathhouse for adults on the shore of Lake Miyazawa in Hanno, Saitama Prefecture, open to guests of elementary school age and up. Here you take in Lake Miyazawa through the four seasons while soaking in Miyazawako Onsen, an alkaline simple spring highly effective for beautiful skin. There are two saunas: a high-temperature sauna with pleasant far-infrared heat and a salt sauna that leaves your skin silky smooth. With a vast warm-stone area called Onnetsubo, a strongly carbonated bath, a reclining bath and much more, it is a spa resort with superb views where body and mind recharge far from the bustle of everyday life.

An airy open-air area on high ground overlooking Lake Miyazawa, with superb views through the four seasons. The water is a alkaline simple spring known as a “bath for beautiful skin”; it gently removes old dead skin cells, leaving the skin smooth to the touch after bathing. Wrapped in rich nature, you can savor onsen water that springs from this very land (water added, heated and free-flowing).

A dry sauna where far-infrared heaters give off powerful heat, drawing a deep sweat from the core of the body. The spacious room is spotless, a quiet space where you can take your time and turn inward. When you step out, the cold plunge right nearby cools your flushed body, and from there you move easily on to cooling off in the open air in the breeze off Lake Miyazawa.

A salt sauna set to a gentle medium temperature. Rub the massage salt kept on hand softly into your skin, and old dead skin cells and sebum clogging the pores are carried away with your sweat, leaving your skin astonishingly smooth after bathing. You can take your time warming up, and it puts little strain on the body, so it is also recommended for anyone who finds high-temperature saunas hard going.

A refreshing cold plunge where the cold pulls your sauna-flushed body taut. Easing in slowly, cooling first the parts farthest from the heart such as the hands and feet, stimulates the sympathetic nerves and boosts the metabolism. After the cold plunge, cooling off in the open air awaits in the open-air area surrounded by nature, where you can spend blissful moments in the pleasant breeze that sweeps across the shore of Lake Miyazawa.

A vast warm-stone area where far-infrared heat radiating from a Mongolian-style bulgama kiln in the center gently warms you to the core. Choose your favorite from several natural stones with different medicinal properties, such as tourmaline and maifan stone, and enjoy detoxing in your own way. There is also a low-temperature warm-stone room for those who don’t like strong heat and a cooling room to soothe a flushed body, making this a blissful wellness space where you can relax all day.
