I Looked Into Unzen Fukudaya

This blog mainly focuses on campgrounds and day-trip hot springs, but in a category I call "Hokansu Detours" (my term for hotel-vacation side trips), I sometimes veer off track to look into long-established ryokan that are more about overnight stays.

This time I looked into Unzen Fukudaya, located in Unzen Onsen in Nagasaki Prefecture. What caught my attention was an open-air bath described as an "infinity bath," plus the fact that the private baths seemed to allow day-trip visits.

What Kind of Ryokan Is Unzen Fukudaya?

Unzen Fukudaya is apparently a ryokan located in Unzen Onsen, in Obama-cho, Unzen City, Nagasaki Prefecture. Since opening in 1968, it seems to have welcomed over 1.1 million guests, making it a place with quite a bit of history. The rooms in the main building were reportedly renovated in spring 2023, and it seems to have been featured in the Michelin Guide Fukuoka Saga Nagasaki 2019 Special Edition.

As for specific business hours or check-in/check-out times, I couldn't find any mention of them on the official website, so that remained unclear. Room reservations seem to be handled through external booking sites, and the official website doesn't appear to list specific room rates either. If that's something you're curious about, it looks like you'd need to check when making a reservation.

As someone who barely drives, I found it quietly reassuring that there was public transit timetable information available. That said, I couldn't tell exactly how many minutes it takes on foot, so it might be best to check a transit app.

Looking Into the Signature Kunpu no Yu and the Private Baths

What caught my eye most among this ryokan's baths was the panoramic open-air bath called Kunpu no Yu, located in the annex called Sansho Bettei. It's apparently an "infinity bath" that lets you feel immersed in the scenery, and it comes with a sauna too. However, this one is reserved for overnight guests only, with the men's and women's sides swapping between morning and evening, so it's worth noting that day-trip visitors can't use it.

The main building also seems to have an open-air bath with continuously flowing spring water called Seseragi no Yu, an indoor bath with a sauna called Fugen no Yu, and a bath called Hakuun no Yu that offers both a hot and a lukewarm option—but these are also reserved for overnight guests only.

On the other hand, the private baths that day-trip visitors can use are apparently Hi no Ki no Yu and Santaro no Yu. Each session runs 50 minutes, with pricing seemingly set at 1,500 yen per person for Hi no Ki no Yu and 1,000 yen per person for Santaro no Yu, with children charged half price and those under 3 free. The water is said to be a sulfur-type spring (a simple acidic iron(II) sulfur spring), reportedly effective for conditions like hypertension, arteriosclerosis, and chronic skin ailments. I couldn't find the reception hours for day-trip bathing listed on the site, so it seems best to confirm that when booking.

Checking Out the Rooms, Meals, and On-Site Facilities

The main building offers several room types—Mountain View Twin, Panorama Twin, Loyly Sauna Twin, and Premium Twin—while the annex, Sansho Bettei, reportedly has seven rooms named Fuku, Un, Chu, Shin, So, Rin, and Ha. Since the atmosphere seems to vary quite a bit by room, choosing one looks like it could be part of the fun at this ryokan.

There seem to be multiple dining options, including a dining hall called Nabe Danran, a teppanyaki restaurant called Sakurabashi, a tempura restaurant called Kofuku serving Unzen-style tempura, and a mountain cafe called Riki (RICKY). The building also reportedly features a lobby lounge called DANRO, a gift shop called Fuku Musubi, and even a private gym called On. Despite being a ryokan, it left me with the impression that you could spend your time in a slightly more resort-like way.

Rakuten Mobile Signal Conditions

When I checked this facility's location using the official "My Area Coverage Simulation" tool, the overall rating came back as a "C." I'll just share that result as it was.

Perhaps because it's a hot spring area tucked away in the mountains, signal conditions might vary quite a bit depending on the exact spot. If you're planning to use mobile data during your stay, it might be reassuring to check the official tool beforehand.

Seeing the C rating made me brace myself a little, but then again, I figured that a place like this might actually be perfect for setting your phone aside and focusing on the hot spring and the scenery.

Looking Into the Surrounding Hot Spring District

Since it's located within the Unzen Onsen district, the surrounding area apparently has spots like Unzen Jigoku (Unzen Hell), the day-trip hot spring Kojigoku Onsenkan, and the public bathhouse Unzen Shinyu Onsenkan scattered nearby. However, I couldn't find specific details about the distances or walking times to each on the site, so that remains unclear. It seems like a good area for strolling around the hot spring district at your own pace.

Wrapping Up

To sum it up, Unzen Fukudaya is a long-established ryokan founded in 1968 that has welcomed over 1.1 million guests, and what stood out to me was that you can visit for the day using its private baths even without staying overnight. Since the signature Kunpu no Yu is reserved for overnight guests only, if that view is what you're after, you'd need to consider booking an overnight stay.

As for Rakuten Mobile, the signal rating came back as a C, so if connectivity is a concern for you, checking the official tool beforehand might give you peace of mind. Some details, like room rates and the reception hours for day-trip bathing, remained unclear, so it seems best to confirm those with the official website or by phone before booking.
