I Looked Into Omuro no Mori Gyokusui

Besides campgrounds, I sometimes look into accommodations in this series too, for those days when I'm in the mood for a "hotel-cation" instead.

This time I looked into "Omuro no Mori Gyokusui." I came across information suggesting that every room apparently comes with its own open-air hot spring bath, and as someone who's more of an indoor type, that caught my interest, so I decided to dig a little deeper.

An Atmosphere of a 9-Room Adult Retreat Perched on a Hilltop

Apparently, Omuro no Mori Gyokusui is an inn built in a hilltop area of Ito City, Shizuoka Prefecture. I had previously come across information stating there were "9 rooms total," but when I checked the official website's main text again, I couldn't actually find a clear statement of the total room count. As for room types, I confirmed three: a Hollywood twin Japanese-Western style room on the top floor (capacity of 4, 60 square meters), a Hollywood twin Japanese-Western style room with two connecting rooms on the standard floor (capacity of 4, 60 square meters), and a queen double room with two connecting rooms on the top floor (with an adjoining Japanese-style room, capacity of up to 4, or up to 3 if using only the Western-style room, 60 square meters).

I couldn't find specific pricing ranges or check-in/check-out times in the main text of the official website, so it seems you'd need to check a booking site or call directly for those details. Reservations also seem to be accepted by phone, but I haven't included the number here, so if you're curious, checking the official website directly should be the surest way. It's apparently about a 5-minute drive from Izu-Kogen Station on the Izu Kyuko Line, and there's also a shuttle bus running every 20 minutes between 2:20 PM and 5:00 PM. That said, using the shuttle apparently requires a phone reservation in advance.

Since I'm basically a driver who never actually drives, an inn with a shuttle bus already puts my mind at ease a bit. But since it apparently requires advance reservation by phone, if I ever go, I'd need to call ahead early.

Ocean-View Open-Air Baths in Every Room, With Flowing Natural Spring Water

The biggest highlight of this inn does seem to be the open-air bath attached to each room. The official website's room page describes an ocean-view open-air bath "sized so that two people can comfortably soak together," and this apparently comes with every room type. The hot spring is said to be maintained by a dedicated hot spring keeper and kept as flowing natural spring water, though the main text doesn't mention the specific mineral composition, the name of the spring source, or the exact temperature. There is a link to a PDF hot spring analysis table, but I wasn't able to check its contents. I also didn't see any mention of a private rental bath in the main text, so it seems the style here is to enjoy the open-air bath in your own room rather than a separate shared private bath.

Inside the building, there apparently is a lounge with ocean views, an esthetic treatment room, a study furnished with a record player and aroma pot, and a private-room restaurant called "Izumi." Meals, both breakfast and dinner, are apparently served in this private-room restaurant rather than in your own room. Dinner starts at either 6:00 PM or 6:30 PM, and if you arrive after 7:00 PM, dinner apparently can't be served at all, so it's worth keeping an eye on your arrival time. Colorful yukata robes are also apparently available for female guests.

• Food allergy accommodations: They apparently use a service called "CANEAT," and registration is needed by 5:00 PM two days before your stay
• On-site facilities: lounge, esthetic treatment room, study, private-room restaurant "Izumi," gallery, shop, terrace, fireplace, and more
• How to book: by phone (reception hours 8:30 AM to 7:00 PM) or via the "RESERVATION" button on an external booking site

Nearby Sightseeing Spots Also Seem to Lean Quiet

For nearby sightseeing, a spot with a view of Mount Omuro's silhouette is apparently about a 10-minute drive from Izu-Kogen Station, with a visit taking roughly 90 minutes. The official website also mentions other spots such as Nikko Falls area (roughly 30 minutes), Matsukawako Lake (roughly 30 minutes to 2 hours), Gran Illumi (roughly 2 hours), and the Izu Kogen Stained Glass Museum Michel Garden Court (about a 5-minute drive from Kawana Station on the Izu Kyuko Line, roughly 1 hour). That said, some of these distances may be measured from JR Atami Station or Ito Station rather than from Gyokusui itself, so the actual distance from the inn might differ. I also couldn't find any mention in the main text of whether parking is available, how many spots there are, or what it costs, so if you're planning to drive, it's probably safest to check in advance.

Rakuten Mobile Signal Conditions

When I checked this facility's location using the official "My Area Connectivity Simulation" tool, the overall rating came back as "C." Since this is the rating the tool actually produced, I'm just reporting it as-is.

Given that it's a hilltop location, it does seem like a good idea to check the signal environment beforehand. It might be reassuring to factor in the building's Wi-Fi availability alongside this. If you have a stay planned, it's probably worth checking with your own device before you head out too.

With a C rating, personally I think I'd just switch my mindset during the stay and not worry too much about my phone's connection, and instead relax in the open-air bath and the lounge. That kind of feels like one valid way to spend a trip too.

Wrapping Up

Putting it all together again, my impression of Omuro no Mori Gyokusui is that it's an adult-oriented inn where every room has its own ocean-view open-air hot spring bath, letting you relax and enjoy flowing natural spring water along with meals at a private-room restaurant. There were some things I couldn't confirm from the main text, like the total number of rooms, pricing, and detailed mineral composition of the spring, so if you're actually considering booking, it's probably best to check directly with the official website or by phone. Since the Rakuten Mobile signal came back as a C rating, if you're counting on connectivity, it's probably reassuring to check the official tool ahead of time.
