Ohara Onsen is a hot spring town in Kyoto, Japan. The water leaves the ground at 27.9°C, cool enough that the baths here are usually reheated. It measures pH 8.7 — mildly alkaline, the slippery kind. Officially the water is classed as simple spring, bicarbonate spring and radioactive spring. Its sources put out around 119 litres a minute.

The water here
Simple spring 単純温泉
Mild and low in dissolved minerals. Usually clear and gentle on the skin, which is why these baths are often recommended for first-timers.
Bicarbonate spring 炭酸水素塩泉
Smooth, slightly slippery water. Often nicknamed bihada-no-yu, the water for beautiful skin.
Radioactive spring 放射能泉
Contains trace radon that leaves the water quickly. Also called radium or radon springs.

With tattoos
Many public baths still turn away visible tattoos, and the rule is set by each bath, not by the town. The reliable way round it is to bathe privately: a room with its own open-air bath, or an inn with a private bath you can book for yourselves.
