Anraku Onsen Tsuru no Yu / 安楽温泉 鶴乃湯 Kagoshima also has its own Tsuru no Yu. A retro onsen with 100% hot spring water. It is not diluted, nothing is added, and it is served as is. All the signs around the place say so. “100% hot spring water, 100% results.” Inside there are 2 baths, an utase-yu and even one rotenburo. There used to be a sauna, but it is no longer in operation. The water is really something, very pleasant and oily, and the temperature is higher than usual, though I did not have a thermometer. It felt like 44-45. So first I went into the mizuburo, then into the main bath, and repeated that 3 times :) Included in Kyushu 88
