I Looked Into Ocean Spa Fuua
2026-08-27

Besides campsites, I've also been continuing to look into day-use hot spring facilities as options for days when I feel like packing up the tent and relaxing in a hot spring instead.
This time I looked into Ocean Spa Fuua in Atami. I heard that its standing outdoor bath with a view over Sagami Bay is its signature feature, and even as an indoor type, that made me want to see the view for myself — that's what got me started.
It seems to be a day-use hot spring that combines a standing outdoor bath with a full view of Sagami Bay and a rest lounge called "Atami Living," letting you enjoy a kind of hotel-staycation vibe.
According to the official tool, the Rakuten Mobile signal condition came out as a C rating.
I've summarized the details below.
A Day-Use Hot Spring Famous for Its Standing Bath Overlooking Sagami Bay
Ocean Spa Fuua is apparently a day-use hot spring facility attached to the Atami Korakuen Hotel in Atami, Shizuoka Prefecture. It's operated by Atami Bay Resort, the same company that runs the hotel, and it seems the day-use bathing area is built right into the hotel building.
Business hours run from 10:00 to 22:00 (last entry at 21:00), and apparently no reservation is needed — you just show up on the day. There seem to be a few closed days set each year, so if you're planning a visit, it might be a good idea to check the calendar on the official website first.
The pricing seems to be structured so that it changes depending on the time of day.
- Regular rate (weekdays): adults 3,080 yen, children 2,310 yen
- Regular rate (weekends, holidays, and specific days): adults 3,410 yen, children 2,530 yen
- After 5 (from 17:00, weekdays): adults 2,310 yen, children 1,760 yen
- After 8 (from 20:00, bathing only, weekdays): adults 1,110 yen, children 770 yen
- All the above prices are tax-included, and apparently a separate bathing tax (150 yen per adult) is added on top
They also seem to accept inquiries by phone, so if you want to confirm the finer details, calling them directly might be a good option.

I felt like if I didn't check this pricing-by-time-slot system carefully, I could end up losing out. My impression is that going later in the evening seems like the better deal.
A Relaxing Rest Space at 'Atami Living'
What caught my attention facility-wise was the rest area called 'Atami Living.' Apparently there are eight uniquely themed lounges available, which gives the impression that you could spend your time lounging around between baths. As an indoor type, the quality of a rest space like this matters to me almost as much as the hot spring itself.
There also seem to be sauna-related facilities where you can try Aufguss steam sessions, along with warming programs like stone bed baths and hot-spring talk baths. However, I couldn't clearly confirm on the official website whether the stone bed bath and Aufguss sessions are included in the admission fee or require an extra charge. It might be worth checking with them in advance.
Light meals and drinks are available at the cafe and restaurant, and relaxation options such as esthetic treatments, hand massages, and body scrubs are also offered, so this place seems well suited to spending a whole day relaxing there. Discounts for Atami Korakuen Hotel guests, discounts for presenting partner cards, and point-exchange plans were also mentioned.
Access by Shuttle Bus, Even Without a Car
Since I'm essentially a non-driver, access without relying on a car is something I care about. After looking into it, it seems that Atami Korakuen Hotel and Fuua share a free shuttle bus service.
It takes about 10 minutes from Atami Station to the facility, and the pickup point appears to be near the roundabout to the right as you exit the ticket gates (in front of the McDonald's there). No reservation is needed, but since seating is limited, apparently there's a chance you might not be able to board. The bus runs fairly frequently, departing from Atami Station between 9:40 and 19:10 at roughly 30-minute intervals, for around 30 runs a day. Outside of that time window, the guidance suggests using the regular route bus bound for Atami Korakuen or taking a taxi.
Even for someone like me without a car, combining the train with the shuttle bus seems like it would make for a manageable trip.
Rakuten Mobile Signal Conditions
When I checked this facility's location using the official "My Area Connectivity Simulation" tool, the overall rating came out as a "C."
Since this is a hot spring facility, depending on the structure of the bathing areas and rest areas, there may be spots where the signal doesn't reach well. If you use Rakuten Mobile and plan to use it inside the facility for things like contacting family or using payment apps, it might be a good idea to check with the official tool beforehand.

Honestly, a C rating feels like a somewhat iffy number to me. If you're planning to check your phone while soaking in the hot spring, it might be best to mentally prepare yourself in advance.
Wrapping Up
To sum it up, my overall impression of Ocean Spa Fuua is that it's a facility that caught my attention while researching day-use hot springs in Atami, combining a standing outdoor bath overlooking Sagami Bay with a well-equipped rest lounge. The time-based pricing system and the ease of access via the free shuttle bus also felt like welcome points for someone like me who doesn't drive.
On top of that, since the Rakuten Mobile signal condition came out as a C rating, if network connectivity matters to you, it might be reassuring to check with the official tool once before visiting.
