Bathing Arrangements

Mixed BathingNo

Shared bathing area for all genders

A pre-rebrand (2017) review describes two separate baths (one view, one no-view), implying a standard gender-separated layout rather than mixed bathing; no source mentions 混浴. Bath structure is unlikely to have changed in the 2026-07-18 rebrand, but this is not independently restated post-rebrand.

Chloride
Hot source · 72°C
Known good for
  • Warmingcold sensitivity
  • Aches & jointsstiff shoulders
  • Smooth skindry, rough skin

A hot sodium-calcium chloride spring rising from the wellhead at 71.7 °C — among Japan's hottest natural sources. Weakly alkaline, with 6.4 g/kg of dissolved solids, it leaves a noticeable mineral film on the skin and stays warm long after the bath. Sulfate adds a quiet body to the chloride backbone, giving the water real substance.

About

TAOYA Atami sits on the hillside at Izusan (伊豆山), above Sagami Bay, and reopened in July 2026 after a full renovation (it was previously known as Hotel Suiyotei). The centerpiece is a new infinity-edge outdoor bath, its rim blurring into the sea, alongside an indoor communal bath. The water is a blend of the Hashiri-yu (走り湯) and Izusan springs, said to be one of Japan's three oldest hot springs with roughly 1,300 years of history behind it.

199. Ooedo Hotel Suiyotei, Atami ★ I stayed overnight, but did not take meals. It looks like a large hotel, about five minutes by car from Atami Station. The main highlight of the hotel is the outdoor bath in the rocks with a great view of the bay. There is a separate path to the bath, partly along the street. As I understood it, it alternates between men and women. At the top, the only amenity is one shower. The water is clear and hot. Beyond the fence there was also a shallow bath a little lower down, but it was empty and used as a drain. In the indoor area: 1. The main indoor bath with a view of the bay. On paper it looked interesting, but in reality the view is not that great, and the glass spoils the scenery. The water is clear, temperature 40. 2. Next to the main bath there is an extra bath. There is also a partial view. The water is clear, temperature about 41. 3. A round bath with a bubble area. The water is clear, temperature 43. 4. Sauna. 5. Cold-water bath. For me, this turned out to be the best option near the station, with a very good outdoor bath and the option to book without meals, since in my plan breakfast and dinner did not fit the timing for this slot. Worth considering if you are looking for accommodation in Atami. 18.07.2024 19.07.2024
