Collection
For many first-time visitors, the idea of bathing naked with strangers is the one thing that holds them back from an onsen. A room with its own hot-spring bath solves that: you bathe when you like, as often as you like, with only the people you came with.
Whether a room has its own bath differs from inn to inn: every room at some, only certain room types at others, and at some a private bath you book separately. Check whether the bath is fed from a hot spring or heated tap water, and whether it is open-air or indoors. The table below sets this out room by room for the properties we have checked on their official sites; the stay reports on each page often show the rest.
What each property’s official site says about the bath in the room. Not a ranking. “All rooms” and “some rooms” are as the hotel states them; “Not confirmed” means we could not find it, not that it is missing.
A bath in your room and a private bath you reserve by the hour are different things. For what the terms mean, see private onsen terms explained.

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.
ATAMI せかいえ
On high ground at Izusan in Atami, with every room facing the sea. Each has an open-air hot spring bath turned towards the water, and the view runs out towards Hatsushima. It keeps the number of rooms low.

THE HIRAMATSU 軽井沢 御代田
A grand auberge in the woods at Miyota, next door to Karuizawa. The rooms face the forest and each has its own hot spring bath. Being away from the centre of Karuizawa, there is little built up around it.

ふふ 箱根
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.

翠嵐 ラグジュアリーコレクションホテル 京都
On the bank of the Oi river, east of Tenryu-ji in Arashiyama. Wings kept from a Meiji-era villa stand alongside modern ones, so the building your room is in changes what the room is like. The garden makes use of the riverside setting.

箱根・翠松園
An all-suite ryokan on the high ground at Gora, with a wing that carries over the design of an early Showa villa. The rooms run to around 100 square metres, large for Hakone, and each has a hot spring bath.

A resort near the top of a hill in Kirishima, Kagoshima, where only five villas with their own hot-spring baths stand far apart from one another. Three are for overnight stays: Tenku, the largest on the property; Akanesasu Oka, built to face the sunset; and Rinu no Mori, wrapped in forest. The other two are for day use only. Every villa has an open-air bath looking out over the landscape. It was opened in 2004 by Tateo Tajima, who founded Gajoen at Myoken Onsen.

ふふ 旧軽井沢 静養の森
