I Looked Into Azumaen

Under a category I call 'hotel getaway detours,' I've been gradually researching accommodations that caught my eye while visiting day-use hot springs, and putting them together on this blog.

This time I looked into Azumaen, located in Unzen City, Nagasaki Prefecture. I came across a description of it as a hot spring inn overlooking Oshidori Pond, and even as an indoor type of person, I thought I'd at least like to take in that view.

A Japanese-Style Resort Inn Overlooking Oshidori Pond

Azumaen is an inn located in the Unzen hot spring area, in Obama-cho, Unzen City, Nagasaki Prefecture. Its location overlooking Oshidori Pond below appears to be one of its biggest highlights. Apparently, every room is designed to overlook this pond, so the time spent in your room comes with the view built right in.

There's also a wide variety of room types — eight in total, it seems, including Suiiro (renovated in 2023), Matsurika, and Riyui, each with its own open-air bath fed by the inn's spring source; Azuma and Subaru (with cypress semi-open-air baths, renovated in 2020), which serve as the deluxe suites; and Suien, Koryoku, and Wakakusa, which come with semi-open-air baths. You can also choose from special rooms, Japanese-Western style rooms, and Japanese-style rooms, so it seems like a place people consider for anniversaries or trips where they want to take things a bit slower.

Check-in is at 3:00 PM and check-out is at 10:00 AM. Reservations can apparently be made through online booking on the official website (which requires membership registration), as well as by phone. There's also a system where booking through the official website gets you 5% off all plans. As for room rates, they seem to vary by plan and season, since I couldn't find specific prices listed on the official site — it looks like you need to check through plan searches or booking sites instead. There also seem to be periods when programs like the Kyushu recovery support discount can be used, so it might be worth checking for that when you book.

With eight different room types, just picking one probably takes quite a while. If it were me, I feel like I'd end up choosing based on the pond view.

The Inn's Own Continuous-Flow Hot Spring and Its Private Baths

Azumaen's hot spring comes straight from its own source with a continuous flow. The water quality is a simple acidic spring (containing hydrogen sulfide), with a source temperature of 55.0 degrees Celsius. It's said to contain a notably high amount of metasilicic acid — an ingredient known for its skin-beautifying effects — even compared to other springs in the Unzen area, and it's also introduced as being effective for neuralgia, muscle pain, joint pain, and chronic skin conditions.

The large communal bath, called Yudokoro Rien, seems to let you move between an open-air bath overlooking Oshidori Pond and the starry sky, a cold-water bath, an indoor bath, and a sauna. However, this appears to be reserved for overnight guests only and doesn't seem to be available for day-use bathing. The hours are apparently 5:00 AM to 10:00 AM and 3:00 PM to midnight. If you're thinking of visiting just for a day-use bath, it's probably worth confirming this point in advance.

On the other hand, each of the eight room types apparently comes with its own private bath supplied by the inn's spring source, which sounds like something any overnight guest can use freely without worry. If you'd like to enjoy the hot spring without other people around, this setup might make for a comfortable stay.

The Kaiseki Restaurant Overlooking Oshidori Pond, and Access

The restaurant, called "on the lake," apparently opened in 2021 and serves kaiseki cuisine in a location overlooking Oshidori Pond. The menu seems to center around seafood from the Ariake Sea and seasonal vegetables from the Unzen and Shimabara area. For group or party use — like year-end and New Year gatherings, farewell and welcome parties, or class reunions — there also seem to be options such as all-you-can-drink packages, companion dispatch services, and a meeting room (11,000 yen for 3 hours).

As for access, there's apparently a free shuttle service between the Shimatetsu Bus Unzen office and the inn, about a 3-minute drive away. Free shuttle service also seems to be available for getting around within the Unzen hot spring town, so even for someone like me who has a license but doesn't drive, it seems like it would be relatively easy to get around once you arrive. Nearby spots like Unzen Jigoku, Kojigoku Onsenkan, and Unzen Shinyu Onsenkan appear to be in the same Unzen hot spring town area, though I couldn't find specific distances or travel times listed on the official website.

Rakuten Mobile Signal Conditions

When I checked Azumaen's location using the official "My Area Connectivity Simulation" tool, the overall rating came back as a "C." If you're planning to do online work or make calls during your stay, it might be worth checking the connectivity situation in advance so you can prepare.

A "C" rating is definitely something to keep in mind. Then again, if you're going all the way to a quiet hot spring town, maybe the right move is to relax without worrying about signal at all.

Wrapping Up

To sum it up, Azumaen struck me as a Japanese-style resort inn notable for its views of Oshidori Pond from every room, along with the private baths fed by its own hot spring source that come with each of the eight room types. The large communal bath seems to be for overnight guests only and doesn't appear to be available for day-use bathing, so if you're planning a day trip, it's probably worth checking on that beforehand. The Rakuten Mobile signal came back as a "C" rating, so if that's a concern for you, checking with Rakuten Mobile's official tool beforehand might give you some peace of mind.
