Gunma Kusatsu Town
A hilltop ryokan with open-air hot spring baths in every room, where you can tour two spring sources
"Yuyado Tokinoniwa" is a hot spring ryokan in Kusatsu Town, Agatsuma District, Gunma Prefecture. Built on a hill overlooking the hot spring town and lush natural surroundings, the entire building is covered in tatami mats, so walking barefoot here feels wonderfully relaxing. The baths shared with the sister property on the grounds are divided into two areas: the large bath area and the therapeutic bath area, each fed by different spring sources. From rustic open-air baths to indoor baths lined up with hot and lukewarm water, there are 23 tubs in total. It also features two types of sauna, dry and wet, plus a bench-style bedrock bath, so you can move from one bath to another while taking breaks in the open air. Three private open-air baths that require no reservation, along with open-air hot spring baths in every guest room, create bathing time free from interruption.

One of the bath areas shared with the sister property on the same grounds, fed by the "Wata no Yu" spring. Starting with a rustic open-air bath, a variety of different tubs follow one after another, and as you move from bath to bath, your sense of time gradually fades. The acidic water with the scent of sulfur leaves a slight tingling sensation on the skin, while making your body feel astonishingly light after you get out. Dry and wet saunas, along with a bench-style bedrock bath, are also located in the same bath area, so you can alternate between warming up and cooling down. The bath area is open all day, so you can visit at late night or dawn, though the sauna and bedrock bath are available from the afternoon until midnight.

The bath area filled by the other spring source, "Yukawa no Yu." Designed to evoke the atmosphere of Kusatsu's therapeutic bathing culture, it offers four tubs each for men and women, including indoor baths with hot and lukewarm water side by side, barrel baths with the scent of wood, and tubs where fine bubbles envelop the skin. You can alternate between hot water to warm the body quickly and lukewarm water for a long soak, choosing whichever suits your condition that day. This area is also open all day, making it a good choice both as the finish to a bath tour and for a morning soak.

Three private open-air baths that do not require a reservation. Each has a completely different atmosphere: one nestled among giant rocks, one with a bamboo grove feel, and one hexagonal hinoki bath with light filtering in. If it is free, all you need to do is open the door, and the moment you feel like it, you can have the bath all to yourself without anyone disturbing you. There is no extra charge, and everything from the sunlight dancing on the water to the quiet of the night becomes yours alone.

An open-air hot spring bath in every guest room. It draws from a different spring source than the large bath area, and you can soak as many times as you like while staying in your room wear. Beyond the rising steam, the clear night air of Kusatsu drifts in, and you can sink in without worrying about time. At night, the bath area is softly lit, letting you enjoy the luxury of having the bath all to yourself in the quiet glow. If you get tired from touring the baths inside the building, just return to your room and step back into the water. That is one of the pleasures unique to this inn.

A dry sauna attached to the large bath area. Its dry heat reaches deep into the body, and sweat gradually rises to the surface. In the quiet wooden room, as you steady your breathing, the outlines of your thoughts soften and the tension of everyday life comes off one layer at a time. It is open from evening until late at night, so you can go heat up whenever you like, after dinner or before bed.

A bench-style bedrock bath attached to the large bath area. There is no extra charge, and from the moment you settle in, warmth slowly spreads up your back. Rather than pouring out sweat, it feels more like your body is gently loosened from within, and even a chilled body is warmed all the way through before you know it. If you lie quietly here between bathing sessions, travel fatigue slips away with each breath.
