I Looked Into Hyakunen no Yu

In Komorin's Fantasy Travels, I steadily research day-trip hot springs and campsites that even someone like me—who doesn't own a car and doesn't drive—could actually visit, and I put together what I find into blog posts.

This time, I decided to look into Hyakunen no Yu, located in Ureshino City, Saga Prefecture. Just the name itself has a sense of history to it, and I found myself drawn in by the number "hundred" (hyakunen), so I went digging through the official information.

The Short Version

It looks like this is a day-trip hot spring proud of its abundant beautifying waters drawn from a hot spring source with a hundred years of tradition.
As for the signal, the checking tool didn't return a result, so I'm treating it as "unknown" this time.

I've put together the details below.

What Kind of Hot Spring Is Hyakunen no Yu?

It's apparently a day-trip hot spring located in an area near the center of Ureshino Onsen, in what's known as the Shimojuku district. Above all, what catches your eye is the name "hyakunen" (hundred years), and this facility seems to promote its use of a hot spring source with a hundred-year history. It's also described as using plenty of "beautifying water," so I got the impression that visitors could enjoy the smooth, silky water that Ureshino Onsen is known for.

I wasn't able to confirm the details of the bath layout (such as whether there's a large communal bath, an open-air bath, or a sauna) from the official website. So for this post, I'll stick to the information I could actually confirm. If you're planning to visit, it might be safest to check on-site.

Prices, Hours, and the Family Bath

The hours of operation are apparently from 9:00 AM to 10:00 PM, with the last entry at 9:30 PM. Prices seem to be split between weekdays and weekends/holidays: on weekdays, it's 690 yen for adults and 300 yen for children, while on weekends and holidays it's 840 yen for adults and 350 yen for children. That looks like a pretty accessible price range for a day-trip hot spring.

Hours: 9:00 AM–10:00 PM (last entry 9:30 PM)
Family bath: last entry reportedly at 9:00 PM; this seems to be a private, reservable bath facility
Price (weekdays): 690 yen for adults, 300 yen for children
Price (weekends/holidays): 840 yen for adults, 350 yen for children

It seems quite likely that the family bath requires a reservation, but I wasn't able to find the exact price or booking procedure from the official information. If you're interested, it sounds like you can reserve by phone, so it might be best to contact the facility directly.

690 yen on weekdays is a price that even makes me, a homebody, think "I could casually drop by on a day off with this." Having a family bath available might also be a nice point on days when I just want to relax quietly by myself.

I Looked Into Access

From Ureshino Onsen Station on the Nishi-Kyushu Shinkansen, it's apparently within the area of the Ureshino Onsen Bus Center, about a 13-minute ride away by JR Kyushu Bus, and located somewhere near the center of the hot spring town. I couldn't confirm the exact walking time from the bus center to the facility from the official information, but given that it's within the hot spring town, it seems like it should be fairly accessible by public transportation.

As someone who has a license but doesn't actually drive, it's reassuring just to know that I could take a bus from the station to the hot spring town and then walk the rest of the way. I wasn't able to confirm the number of parking spaces or parking fees, so if you're driving there, it might be safest to check the local information separately.

Rakuten Mobile Signal Conditions

When I tried to check this facility's location using the official "My Area Coverage Simulation," no result was shown, and instead I got a message saying something like "currently undergoing temporary maintenance." This might be the kind of behavior that shows up when the address data for a location hasn't been fully registered yet, but I couldn't figure out the exact reason.

So this time, rather than judging the signal conditions as either "good" or "uncertain," I decided to treat it as "unknown." I'm sharing this as-is, as something I simply wasn't able to determine.

Honestly, when I couldn't get a result, I got a little worried, thinking "wait, did I do something wrong?" But since I got the same message no matter how many times I checked, I decided to just record it as unknown for now.

Wrapping Up

To sum it up again, Hyakunen no Yu struck me as a day-trip hot spring characterized by its abundant beautifying waters drawn from a hot spring source with a hundred-year history. Prices start from 690 yen on weekdays, and since it's located near the center of Ureshino Onsen, it seems like a spot that should be easy to visit even by public transportation.

On the other hand, as for the Rakuten Mobile signal conditions, the checking tool never returned a result, so it remains unknown. If this matters to you, it's probably worth checking again with the official Rakuten Mobile tool before you visit.
