Collection
A night at an onsen ryokan is one of the most distinctive things you can do in Japan: a hot-spring bath, a multi-course kaiseki dinner served in or near your room, and futon or beds laid out for the night.
The water itself differs from place to place, and so does the etiquette. Most communal baths are separated by gender and enjoyed without swimwear; some places have rules about tattoos. Each property page gathers what guests have written and filmed, so you can see the baths before you go.

星のや東京
A tower ryokan in Otemachi, two floors below ground and seventeen above. You take off your shoes at the entrance and walk tatami corridors to your room, a layout carried through the whole building. All 84 rooms sit six to a floor around a shared ochanoma lounge. On the top floor is an open-air bath fed by the Otemachi hot spring, drawn from 1,500 metres below ground.
アマン京都
In a private forest at the foot of Takagamine, north of Kinkaku-ji. It sits away from the city, and the grounds are covered in moss and cedar. The buildings are kept low and scattered, so that walking the garden becomes part of the stay.
アマネム
A hot spring resort inside Ise-Shima National Park, on high ground looking down over Ago Bay. Low buildings are spread across the slope, and every room has its own indoor hot spring bath.

HOTEL THE MITSUI KYOTO
Directly opposite Nijo Castle, on the site of the Mitsui family’s own residence. You enter through the Kajiimiya gate, moved here and rebuilt, and the guest wings stand around a garden at the centre. A thermal spring drawn from under the grounds feeds the bathhouse.

ROKU KYOTO
A low-rise resort at the foot of the Takagamine hills, next to the Shozan gardens. It has a communal bath fed by a natural hot spring and an outdoor pool facing the garden. Being out of the city, it is quiet in a way the centre is not.
ATAMI せかいえ

THE HIRAMATSU 軽井沢 御代田

A mountain resort ringed by the Hakone range. Every room has a hot-spring bath in a bathroom whose windows open wide — not a separate outdoor bath. The rooms use Gora onsen and the communal baths Owakudani onsen, two different springs. The buildings are kept low along the slope, so what fills the windows is green.

強羅花壇
A long-established ryokan at Gora, on the site of a former imperial family villa. The buildings step down the slope, and the long corridors and the windows keep the mountain green in view. Some rooms have their own open-air bath.
星のや軽井沢

由布院 玉の湯
A ryokan standing in about 10,000 square metres of coppice woodland in the Kawakami area of Yufuin. It began in 1953 as a retreat for a Zen temple and became an inn while keeping those buildings.

The public bath has both an indoor and an open-air bath on the men’s and the women’s side, and Mount Yufu is in view from the open-air one.

ふふ 旧軽井沢 静養の森
