I Looked Into Oyado Uchiyama
2026-09-30

This blog is mainly about campsites, but every now and then I take a detour and think 'let's skip camping and go for a hotel getaway instead,' so I keep researching various accommodations along the way too. This time is one of those detour posts.
This time I looked into Oyado Uchiyama. I heard it's a hideaway-style inn where every room comes with its own open-air bath, and as someone who's very much an indoor type, the idea of spending a whole day just soaking in the bath really appealed to me, so I decided to look into it.
It's a detached-cottage inn with only 6 buildings, and the biggest draw seems to be the luxurious setup where every room comes with two open-air baths.
The Rakuten Mobile signal came back as a "C" rating on the official tool, so it seems like a good idea to check that in advance.
I've put together the details below.
A Hideaway Inn With Just 6 Detached Cottages
Oyado Uchiyama is apparently located in the Izu Kogen area of Ito City, Shizuoka Prefecture. It sounds like a place with views of the Izu Islands and the Amagi mountain range, where only 6 two-story detached cottages stand — the kind of inn that limits itself to just 6 groups per day.
There are 6 rooms named Waremokou, Hoozuki, Rurisou, Tokisou, Nadeshiko, and Sasayuri, and each is apparently grouped into one of three types: flower, moon, or snow. The flower type (Nadeshiko and Sasayuri) has an open bath with ocean views, the moon type (Rurisou and Tokisou) has an atmosphere where you can soak while feeling the moon and stars, and the snow type (Waremokou and Hoozuki) has more of a tucked-away, second-floor feel — so each type seems to offer a different way of enjoying the open-air bath. Since every room apparently comes with two baths, it seems like you could switch tubs depending on the time of day or your mood.
Check-in is apparently from 3:00 PM to 6:30 PM, and check-out is normally 11:00 AM, though it's noted that as a booking perk for reservations made through the official site, check-out can sometimes be extended to noon. That might be a nice point for anyone who wants to take things slow. As for room rates, I couldn't find any specific figures in the official site's main text — only discount information like a "10% off special plan" or "10,000 yen off for two people." If you're curious, it's probably best to check the official site's availability calendar and plan list, or contact them directly, since they also seem to accept reservations by phone.

Having two open-air baths in a single room made me think, honestly, 'will I really have time to use both?' But then again, I guess that just means the place is designed to make you want to stay longer — that's the conclusion I landed on, anyway.
Enjoying Meals in the 'Uchiyama-Style Kaiseki' Way
At Oyado Uchiyama, meals are apparently served in a style called 'Uchiyama-style kaiseki.' The dishes seem to be centered around spiny lobster, splendid alfonsino, seasonal seafood, and quality meats. The signature breakfast item is reportedly abalone in a thick sauce along with rice cooked in an earthenware pot, which sounds like a satisfying way to start the day. Depending on the plan, they also offer kaiseki-style meals with live spiny lobster served in your room, which might suit anyone who wants to enjoy a leisurely meal in the quiet of their own cottage.
As for access, it's apparently about a 10-minute taxi ride from Izu-Kogen Station on the Izu Kyuko Line. I couldn't find any mention of a shuttle bus in the official site's main text, so if you need one, it's probably worth confirming in advance. Parking looks like it's set up for 6 cars free of charge, so that should be easy enough to keep in mind if you're driving.
Rakuten Mobile Signal Conditions
When I checked the location of Oyado Uchiyama (the Izu Kogen area) using the official "My Area Connectivity Simulation" tool, the overall rating came back as "C." I'm sharing this as-is, since it's the actual result I got from the official tool.
Given that it's a detached-cottage inn nestled in the mountains, connectivity might vary depending on the exact spot. If you plan to handle work communications during your stay or watch a lot of videos, it's probably a good idea to keep this rating in mind and check things in advance.

Getting a 'C' rating honestly made me go 'huh,' but then, precisely because it's this kind of hideaway inn, maybe intentionally stepping away from your phone for a while isn't such a bad thing. That said, if it's something you're concerned about, I think it's best to check for yourself.
Wrapping Up
To sum it up, Oyado Uchiyama comes across as a hideaway inn with only 6 detached cottages, each equipped with two open-air baths, letting you enjoy different bathing experiences under the flower, moon, and snow themes. The meals are also served kaiseki-style with spiny lobster and splendid alfonsino, so it seems like a good fit for anyone who wants to really enjoy their food too.
On the other hand, the Rakuten Mobile signal came back as a "C" rating on the official tool, so if connectivity during your stay matters to you, it's worth checking in advance. If you're curious, try entering the actual address into the official Rakuten Mobile tool yourself.
