I Looked Into Izu Kogen Hanare Oyado Yumenoya

Not just campsites—I've also been steadily researching inns that could work for those days when you think, "let's skip the camping trip and do a hokans (hotel vacation) instead," as detour spots for Komorin's Fantasy Travels.

This time, the inn that caught my eye was called "Izu Kogen Hanare Oyado Yumenoya." Since the name includes the word "hanare" (detached), it seems like every room is its own independent standalone unit. As an indoor type who tends to worry about other people's eyes, that made me want to look into it a bit, so I got to work.

The Short Version

There are only 6 rooms total, and every single one comes with a natural hot spring semi-open-air bath and its own private terrace, making this a fairly private-feeling inn.
The Rakuten Mobile signal came back as a C rating, so if you want to rely on connectivity, it might be worth checking in advance.

I'll go over the details below.

A Hideaway Made Up of Just 6 Detached Rooms

"Izu Kogen Hanare Oyado Yumenoya" appears to be an inn located in the Izu Kogen area of Ito City, Shizuoka Prefecture. According to the official website, there are only 6 detached-style rooms, and each one apparently has its own spacious entrance porch.
With the number of rooms kept quite limited, the place seems less likely to feel crowded, which should suit anyone hoping for a quiet stay.

The access page notes check-in runs from 3:00 PM to 5:00 PM, and check-out is by 10:30 AM. I couldn't find any specific pricing listed in the main text of the official website, and it looks like bookings go through an external reservation site reached via the "Reservations" link on the official page. If you're curious about the cost, it seems you'll need to check on the reservation site itself.

A Semi-Open-Air Bath in Every Room, Plus a Private Open-Air Rock Bath in the Main Building

Naturally, the hot springs were what caught my attention most about this inn. Every room comes with its own natural hot spring semi-open-air bath, and apparently each one has an openable door to keep out the cold and any insects. Some rooms reportedly offer distant ocean views as well, so the way you enjoy the scenery might change depending on the season and time of day.

On top of that, the main building apparently has a free-to-use private open-air rock bath too. That said, the official website's main text doesn't go into detail about its size or how time slots are divided up, so that's probably something worth confirming when you actually make a reservation.

Having a bath right in your room, and then a private rock bath on top of that—that combination really speaks to someone like me who likes to have a bath all to myself.

About the Monthly-Changing Kaiseki Cuisine

Meals apparently center around local Izu seafood and Kuroge Wagyu beef, served as a kaiseki course that changes every month. It sounds like the head chef carefully selects seasonal ingredients and puts together a colorful presentation that matches the flow of the courses. The official website's main text doesn't specify whether meals are served in-room or in a private dining area, so that's probably something worth checking at the time of booking.

Access and Parking

Access is apparently about a 5-minute drive from Izu Kogen Station on the Izukyu Line. That's a bit of a tricky point for someone like me who doesn't drive, but there does seem to be a shuttle bus running from both Jogasaki Kaigan Station and Izu Kogen Station. Service runs from 3:00 PM to 5:30 PM, and it seems you're supposed to call once you arrive so they can come and pick you up. The official website doesn't clearly state whether advance booking is required for that, so it might be worth confirming by phone if you plan to use it.
There's also apparently free parking available, so that shouldn't be a worry for anyone driving there.

Rakuten Mobile Signal Conditions

Using the official "My Area Communication Simulation" tool, I entered the address corresponding to this facility's location, and the overall rating came back as "C."

Since it came back as a C rating, it's probably worth checking on the local connectivity situation ahead of time. If you're planning to use your phone in a room set apart from the main building, or to get some work done out on the terrace, checking the communication simulation before your stay should give you a better sense of what to expect.

Honestly, that was a bit of a disappointing result. Still, if you're the type to shut yourself away at the inn and focus purely on the hot springs and the food, I have a feeling weak signal might not even bother you all that much.

Wrapping Up

Looking back over everything, Izu Kogen Hanare Oyado Yumenoya struck me as a hideaway-style inn with a strong sense of privacy—every room detached, every room with its own semi-open-air bath, and even a private open-air rock bath in the main building. The food is apparently a kaiseki course that changes every month too, so it seems well suited to the hokans crowd who want a quiet stay centered on hot springs and good food.

That said, there were still some things I couldn't pin down just from the official website's main text, like the detailed room rates and the rules for using the open-air rock bath, so if you're actually considering a stay there, you'll probably need to check the reservation site or call directly. As for Rakuten Mobile, the signal came back as a C rating, so if connectivity matters to you, it's probably worth checking for yourself using the official Rakuten Mobile tool.
