木部谷温泉 松乃湯

You can open the valve for the hot spring source (20.6℃) from inside the bathtub, and when opened, a tremendous amount of hot spring water pours into the tub. However, because the source water temperature is low, the temperature in the tub drops rapidly if left as is. So, you open another steam valve that can be operated from inside the tub, and with a tremendous noise, the steam pipe running through the tub heats the water (it's too hot to get close to the steam pipe, meaning that the hot spring water is not directly circulated and heated, so you can enjoy super fresh hot spring water). If you're lucky enough to be the only one in the tub, you can adjust the water temperature to your liking and enjoy the hot spring – this is a very rare hot spring facility in Japan that uses free-flowing hot spring water. Of course, the water quality is also excellent. There are lockable changing room lockers, showers, and faucets. Only bar soap is provided. Colored towels are better; white towels will turn reddish-brown due to the iron content. There is also a restaurant, so you can enjoy lunch and a day trip to the hot springs. The hot spring water is drawn from a geyser on the mountain right behind the facility, along the base of the mountain. There is also a drinking fountain outside.

It would take a long time to explain. The definition of an artesian spring would also take a long time to explain. I'm not a geology major. The ground isn't very deep, so architectural techniques aren't that useful. But this facility is an artesian spring due to crustal movement about 7km deep. Apparently, it erupts every 35 minutes. And apparently, it gushes out like a stimulating Coke bottle. When the pressure drops below saturation, does it become water? Or hot water? The deposits and components listed on the hot spring analysis chart are proof, but it's the changes that occur before that. Japan has many wonderful facilities. I respect them. There are various types, such as drilled artesian springs and well-raised springs, and this story makes you think about what real hot spring water is. P.S. What are the benefits of this hot spring? What does it feel like? How happy did you enjoy soaking in it? That's up to you. But I'm grateful to my predecessor, who passed away. #Matsunoyu 530 Kibedani, Yoshiga-cho, Kanoashi-gun, Shimane Prefecture 699-5307

Shibuyu has a striking, true orange color. It's as orange as the soil along the road to the geyser. The unique grip of iron and the mellow taste of salt coexist here. The source water is 20 degrees, so it's heated to just the right temperature. The water quality is similar to that of the nearby Kakinoki Onsen, but since it's only open for a short time, if you can try something rare, this might be the better choice.

Although it's a drilled spring, this geyser, which erupts naturally with carbon dioxide, is rare in Japan and is free to see, so I recommend it. However, I feel that the force of the eruption has weakened a bit compared to the past. The water quality is excellent, but the erupted water goes directly into the bathtub, so it might not be suitable for people who are very particular about cleanliness.

This is my third time visiting since it reopened. I had been using it before it closed, but when it did I had no choice but to use other hot springs. I found out about the reopening on Instagram and immediately visited. The previous proprietress has been replaced by her son, but the hot springs and food are just as great as before.
