A hot simple thermal spring (71.1 °C, neutral pH) — light in mineralization at 673 mg/kg dissolved solids, yet rich in metasilicic acid (195.7 mg/kg). Colorless and clear at the wellhead; by 24 hours after sampling the water has taken on a faint yellow-brown tint and a mild mineral note. The silica leaves the kind of thin film that makes skin feel noticeably smoother — the source sits squarely in the Japanese 'beauty-water' family.

About

A facility specializing in a variety of family baths. It is about a 5-minute drive from Beppu Interchange, making access convenient. Surrounded by the greenery of trees in a rich natural environment, the bath tubs are diverse, made of stone, rock, cypress wood, and more. There are open-air baths, semi-open-air baths, and indoor baths. Detached baths arranged like bungalows allow you to relax without worrying about neighbors, and there are also row-house type baths. Each family bath has a different atmosphere, so you will want to visit many times and soak in various types of baths. Of the 10 rooms, 2 are free-flowing hot spring baths, and 8 are coin-operated baths. You can fully enjoy fresh water just for yourself with the coin-operated baths, as well as the benefits of the free-flowing hot spring baths.

We were lucky — a rotenburo was available. It was very large, beautifully decorated, with a roof and lighting. We didn't need to fill the water ourselves, everything was already filled, but you could freely adjust the temperature. We added cold water and I was surprised at how quickly such a large bath cooled down.

154. Beppu Ohirayama Onsen OKATANOYU ★ An onsen that offers private baths only. There are 10 to choose from, with prices from 1,500 to 2,500. The nearest one was 1,500, so I took that. There is a stamp. When they led me to my bath, it turned out that the bath was empty inside and I had to fill it myself, I do not know whether all the baths there are like that. To do this, I had to drop in a special coin, and hot spring water started flowing from a large pipe. You could also immediately mix the hot water marked as onsen from the tap with cold water, obviously tap water. The hot spring water was clear and very hot. If you did not dilute it with cold water, it would have been impossible to sit in it. The air inside the building was easy to breathe. A good place, a very fun experience to fill the water yourself, and the choice of baths is interesting too. 03.05.2024
