Saitama Hanno City
Enjoy the best location and the finest relaxation to your heart's content
Miyazawako Onsen Kirari Bettei is an adults-oriented day-use hot spring facility for elementary school age and older, nestled on the shores of Lake Miyazawa in Hanno City, Saitama Prefecture. While enjoying the changing scenery of Lake Miyazawa throughout the seasons, guests can fully savor Miyazawako Onsen and its alkaline simple spring, known for its skin-beautifying benefits. The sauna area features two types: a high-temperature sauna with soothing far-infrared heat, and a salt sauna that leaves the skin feeling silky smooth. With a spacious bedrock bath area called Onnetsu-bo, a high-concentration carbonated spring, reclining baths, and many other facilities, this scenic spa resort offers a refreshing escape for both body and mind from the noise of everyday life.

Located on a hill overlooking Lake Miyazawa, this open-air area offers spectacular seasonal views. The spring water is a weakly alkaline simple hot spring known as a skin-beautifying bath, gently removing old dead skin cells and leaving the skin smooth after bathing. Surrounded by abundant nature, you can enjoy the hot spring that springs from this land, with added water, heating, and free flow directly from the source.

This dry sauna is powered by far-infrared heaters that release intense heat, encouraging deep sweating from the core of your body. The spacious interior is clean and quiet, making it a place where you can focus inward and spend time with yourself. After leaving the sauna room, you can cool down in the nearby cold plunge bath and then smoothly transition to an outdoor air bath while feeling the breeze from Lake Miyazawa.

This gentle medium-temperature salt sauna is easy on the body. By softly rubbing the provided massage salt onto your skin, old dead skin cells and sebum trapped in your pores are washed away with perspiration, leaving your skin amazingly smooth after bathing. It warms you gradually and places less strain on the body, making it a good choice for people who are not comfortable with high-temperature saunas.

A refreshing cold plunge bath that sharply tightens the body after a sauna session. By soaking slowly while cooling your body little by little from the hands and feet, which are far from the heart, the sympathetic nervous system is stimulated and metabolism is boosted. After the cold plunge bath, an outdoor air bath in the naturally rich open-air area awaits, where you can spend a blissful moment feeling the pleasant breeze that blows across the Lake Miyazawa shore.

A spacious bedrock bath area warmed deeply to the core by far-infrared rays emitted from the Mongolian-style fire furnace called a "higama" at the center. You can choose your preferred bedrock from several types of natural stone with different therapeutic properties, such as tourmaline and bakuhanseki, and enjoy detox in your own style. It also features a low-temperature stone room for those who do not like intense heat, as well as a cool room to soothe a body that has become too warm, creating a blissful wellness space where you can relax all day long.
