I Looked Into Itamuro Onsen Daikokuya

On this blog, I've been running with the theme of 'let's skip camping today and go for a hokance (hotel + vacance) instead,' continuously looking into hot spring ryokans that even indoor types like me might enjoy. Since I don't drive, whether or not a place is reachable without a car is quietly a point I care about.

This time I looked into Itamuro Onsen Daikokuya, located in Itamuro Onsen in Nasushiobara City, Tochigi Prefecture. I heard it has an open-air bath where you can listen to the murmur of the Naka River, and as someone who prefers to stay indoors, that made me want to take a look at it from my desk (well, through my browser).

The Short Version

My impression was that of an atmosphere-focused hot spring ryokan where you can enjoy multiple baths, including an open-air bath where you can listen to the murmur of the Naka River, a cypress bath, and a bath for basking in sunlight.
The Rakuten Mobile signal conditions came back as a C rating, so if you want to rely on connectivity, it seems safer to check in advance.

I've put together the details below.

What Kind of Place Is Itamuro Onsen Daikokuya?

Apparently it's a ryokan located in Itamuro Onsen in Nasushiobara City, Tochigi Prefecture. The official website lists check-in from 2:00 PM to 5:00 PM and check-out at 10:30 AM, which feels about the same timing as a typical ryokan.

The guest rooms are apparently divided across three buildings—Ume-no-Yakata (Plum Building), Matsu-no-Yakata (Pine Building), and Take-no-Yakata (Bamboo Building)—so the atmosphere might differ from building to building. Reservations can be made by phone, and it also seems possible to book through the reservation page on the official website or through booking sites like Booking.com. That said, I couldn't find specific accommodation rates in the text of the official website, so it looks like you'd need to check pricing through a booking site. As for day-use bathing, I couldn't find any mention on the official website of whether it's available or how much it costs, so if that matters to you, calling directly might be the surest way to find out.

The Appeal of Bath-Hopping to the Sound of the Naka River

The water quality is apparently a simple alkaline spring, with the source named Itamuro Onsen, at a temperature of around 40°C, and it's enjoyed as a colorless, clear, source-fed flowing bath. The listed benefits reportedly include neuralgia, various muscular ailments, gynecological conditions, musculoskeletal disorders, and after-effects of injuries.

The baths are apparently named ROTEN NO YU (the open-air bath), TAIYO NO YU (the sunlight bath), and HINOKI NO YU (the cypress bath), each built around its own concept—an open-air bath for listening to the murmur of the Naka River, a bath for soaking up sunlight, and a bath for enjoying the scent of cypress, respectively. The open-air bath was reportedly renovated in February 2023, so the idea of enjoying it in a relatively fresh condition also caught my interest.

The apartment-style accommodation building also seems to come with its own private source-fed flowing hot spring bath, called Hoyo-no-Yakata (Recuperation Building). It looks similar to a private reservable bath, but I couldn't make out the details of the usage conditions from the text on the official website. There's also apparently a café called Suikintei inside the building, so it seems like there are options for how to spend your time beyond just the hot springs.

I could feel the ryokan's attention to detail in the fact that each bath name is given in romanized form. Having a private hot spring is also a happy point for an indoor type like me.

Rakuten Mobile Signal Conditions

When I checked this facility's location (the Itamuro area of Nasushiobara City) using Rakuten Mobile's official "My Area Coverage Simulation" tool, the overall rating came back as "C."

Given that Itamuro Onsen is a hot spring area nestled in the mountains, it may well be an area where signal strength varies quite a bit depending on the exact spot. Considering the C rating, it seems wise not to rely too heavily on connectivity inside the building, and to take care of any necessary communications ahead of time.

A C rating is honestly not a number that inspires much confidence, so I felt like it'd be just as well to spend the time soaking in the hot spring without worrying about my phone.

About the Surrounding Area

I couldn't find a page introducing the surrounding sightseeing spots on the official website, and the only information I could confirm was that a hot spring town belonging to the Itamuro Onsen Ryokan Association seems to be within walking distance. I also couldn't work out the number of parking spaces, whether shuttle service is available, or public transportation access such as local bus routes from the official website, so I'd like to fill in this part with additional research going forward.

Wrapping Up

To sum up, my impression of Itamuro Onsen Daikokuya was of an atmosphere-focused hot spring ryokan offering multiple baths to enjoy, starting with an open-air bath where you can listen to the murmur of the Naka River. There were a few things I couldn't figure out from the official website alone, such as whether day-use bathing is available and what the accommodation rates are, so if you're actually considering staying there, it seems reassuring to check by phone or other means.

The Rakuten Mobile signal conditions came back as a C rating, so if connectivity is a concern for you, it seems like a good idea to check in advance using Rakuten Mobile's official tool.
