I Looked Into Gyokusuiso
2026-09-10

On this blog, I've been researching hot spring inns and campgrounds that seem easy to visit even for someone like me who doesn't drive, sort of like an ongoing series. This time as well, I did my research with "whether it's accessible without a car" as the main focus.
Actually, the hot spring inn in Okutama that I originally planned to look into seems to have closed down, so I searched again in the Okutama area and found the one I'm introducing today: Gyokusuiso. When I learned it's quite close to Okutama Station, I thought this might actually work for someone like me who has a license but doesn't really drive, so I decided to look into it.
The two-minute walk from Okutama Station—practically right by the station—seemed to be its biggest appeal.
That said, the Rakuten Mobile signal came back as a C rating, so it's probably reassuring to check the connectivity situation ahead of time.
I've put together the details below.
What Kind of Place Is Gyokusuiso
Gyokusuiso is apparently a hot spring inn located in Okutama, Nishitama District, Tokyo. It's built along the Hikawa Gorge, and according to the official site, "every room offers a stunning view of the Tama River below." It gave off the impression of an inn where you can relax while gazing at the gorge.
The hot spring uses water from the Tsuru no Yu source, described as natural Okutama hot spring water with "a faint scent of sulfur." The same source water seems to be used at other inns in the Okutama area too, so it might be a spring that's fairly well-loved around here. However, the day-trip bathing service is currently suspended, so it seems worth knowing in advance that it's only available for overnight guests.
Checking Out the Facilities, Rooms, and Food
There appear to be two room types available: Japanese-style and Japanese-Western style. As for the food, it seems they serve dishes featuring Okutama rainbow trout along with local vegetables.
As for pricing, for a plan with two adults, tax included, one night with two meals, it seemed to range fairly widely—from 14,300 yen for the seasonal kaiseki course, from 13,200 yen for the more affordable kaiseki course, and from 9,900 yen for the business plan. There also seem to be other options like one night with breakfast only from 9,900 yen, or room-only from 7,150 yen. Children's rates appear to be broken down in detail depending on age and meal options, so it seems reassuring to confirm these details when booking if you're traveling with family.
- Check-in/check-out: apparently from 3:00 PM / until 10:00 AM
- How to book: It seems you can search through the official site's online reservation form by specifying your stay dates, number of guests, room type, and budget. Phone reservations are also apparently accepted
- Room types: two options—Japanese-style and Japanese-Western style

Just picturing rainbow trout dishes with a gorge view already sounded pretty appealing to me. It's a bit of a shame that the day-trip bathing service is suspended, but maybe this is the kind of inn meant for a relaxing overnight stay.
Access and Parking Situation
Access is apparently a two-minute walk from JR Okutama Station, which felt like a huge plus for someone like me who doesn't drive. Being this close to the station feels like a pretty favorable condition compared to other places I've researched in this series.
There appear to be 8 parking spots, free and first-come-first-served, and when full, it seems you'd need to use a nearby town-run parking lot (700 yen per day). Also, if you're driving there, there seem to be some narrow sections along the road—both entrances, one on the Ome Kaido side and one just before Showa Bridge, are apparently only about wide enough for a single regular car. Drivers might want to be a little careful there. From my perspective as someone who doesn't drive, being reachable by train was definitely a major point in its favor.
Rakuten Mobile Signal Conditions
When I checked this location using the official "My Area Connectivity Simulation" tool, the overall rating came back as a C.
Since the result was a C rating, it seems worth checking on signal reception ahead of time. If you want to stay in touch for work during your stay, or if you tend to use a lot of data for things like video streaming, it might be reassuring to factor this result in beforehand.

A C rating is honestly just something I have to accept as it is. It might have something to do with being located along a gorge, but it seems like a good idea to plan for a stay that doesn't rely too heavily on connectivity.
Wrapping Up
Looking back over everything, Gyokusuiso struck me as a place whose biggest appeal is being just a two-minute walk from Okutama Station, making it easy to visit without a car. Between the gorge-side scenery, the rainbow trout dishes, and the natural hot spring drawn from the Tsuru no Yu source, it seems like the kind of inn meant for a relaxing overnight stay. On the other hand, the day-trip bathing service is currently suspended, and the Rakuten Mobile signal came back as a C rating, so those are both things worth knowing ahead of time. If that's a concern, you can check using Rakuten Mobile's official tool, so it might be reassuring to take a look before you go.
