I Looked Into Gogaku Hotel

I Looked Into Gogaku Hotel

So far, I've mainly looked into campsites and day-trip hot spring facilities, but lately I've also been checking out business hotels that come with their own hot springs.

This time, I looked into "Gogaku Hotel." Apparently its hot spring has been flowing straight from the source for over 90 years, and as someone who's more of an indoor type, the idea of "staying somewhere just to soak in the hot spring" caught my interest, so I put together some information on it.

The Short Version

It's a business hotel with a hot spring that's apparently been flowing straight from the source for over 90 years, and it seems to welcome solo travelers too.
The Rakuten Mobile signal came back with a "C" rating in my check this time, so if you want to rely on your connection, it's probably worth checking in advance.

I've put together the details below.

What Kind of Place Is Gogaku Hotel

Gogaku Hotel is apparently a business hotel located in the Uchinomaki hot spring area of Aso City, Kumamoto Prefecture. It's about a 5-minute drive from Aso Station on the JR Hohi Main Line, and even if you're heading there by public transportation, it doesn't seem like it would be too inconvenient.

Its biggest feature does seem to be the natural hot spring that's apparently been flowing straight from the source for over 90 years. I felt it might be somewhat rare for a business hotel to have such a proper hot spring. The official website mentioned that it's not just for business use but also welcomes solo travelers visiting just for the hot spring, so it seems like a place that's easy to use even from a solo traveler's perspective.

I Looked Into Room Types and How to Book

It looks like there are three room types available: twin plus extra bed, business twin, and single. This seems to cover a fairly wide range of needs, from solo use on a business trip to stays with a small group.

  • How to book: You can go through the online booking button on the official website to an external reservation system, or apparently book by phone as well
  • Rates: The official website itself doesn't list specific prices, so it seems you need to check through the external reservation system
  • Check-in/check-out times: I couldn't find these clearly stated on either the access page or the profile page of the official website

At the time I checked, there was apparently a campaign called something like "Stay in Aso and Support Kumamoto!" that was available only for direct bookings, but since this seems to be a limited-time offer, it may already be over by the time you're reading this. If you're interested, it's probably a good idea to check the official website for the latest information.

It's a little concerning not knowing the price right away, but when I hear "90-year-old spring source," I can kind of understand wanting to soak in it at least once just for that.

Rakuten Mobile Signal Conditions

Since I use Rakuten Mobile, I checked the location of Gogaku Hotel using the official "My Area Connectivity Simulation" tool, as I usually do.

The overall rating came back as "C." This is the result the company's own official tool actually produced, so I'm sharing it as is. It doesn't seem like there'd be any problem just relaxing at the hot spring, but if you're planning to do anything data-heavy like watching videos or making video calls, it might be a good idea to plan your time there with the signal conditions in mind.

Hearing about a "C" rating does make me brace myself a little, but if the whole point of the trip is the hot spring, maybe it's fine to just go with the mindset of "keep the phone use light and enjoy soaking and relaxing."

The Surrounding Area and a Few Things to Note

Since Gogaku Hotel itself is located in the Uchinomaki hot spring area, it seems like a place where you can enjoy the atmosphere of the hot spring town itself. That said, I couldn't find detailed information on the official website about specific nearby sightseeing spots or restaurants, or how far they are. I also couldn't confirm details about the number of parking spaces, whether pets are allowed, or Wi-Fi availability from the official website's main content, so it's probably safest to contact the hotel directly if you're considering a stay and want to know more about these points.

Wrapping Up

To sum it up again, my impression of Gogaku Hotel is that it's a business hotel featuring a hot spring that's apparently been flowing straight from the source for over 90 years, and one that also welcomes solo travelers. With multiple room types available, it seems like a place that can be used in various ways, from business trips to solo stays focused purely on the hot spring.

That said, there were quite a few things I couldn't figure out just from the official website, like rates, check-in times, and details about the surrounding area, so when actually booking, it's probably reassuring to confirm the finer details by phone or through the online reservation system. The Rakuten Mobile signal came back with a "C" rating, so if you're planning your stay around having a connection, it might be worth checking with Rakuten Mobile's official tool as needed.
