A sodium-led bicarbonate-chloride spring drawn from the Yadori Tamagawakyo source. It is the classic juso-sen style, and an alkaline pH gives it the soft, slippery touch of Japan's beauty-water family. The water is colorless and clear, yet it carries a trace of hydrogen sulfide in both smell and taste — an extremely faint sulfur note that is this spring's signature. The posted analysis documents this particular water for cuts, peripheral circulation disorders, cold sensitivity, depressed mood and dry skin. It reaches the baths heated to a comfortable soaking temperature and undiluted; the indoor bath pairs recirculation with free-flow source water, and chlorine-based disinfection is used to meet the prefectural hygiene standard.

About

Yadori Onsen Iyashinoyu is a small onsen ryokan in the mountains at the foot of Koyasan, on the clear-stream gorge of the Tamagawa river, about halfway between Koyasan and central Hashimoto. The main bathhouse splits its indoor bath into a marble-lined tub and one scented with hinoki cypress, plus a small outdoor bath. The water is pumped up from 1,300 meters underground and feels soft and faintly slippery on the skin. Locals call it bijin-no-yu (美人の湯), a beauty bath. Most guests come to stay in one of four freestanding cottages that sleep up to six, two of which have their own private indoor onsen. It also works well as a day trip: plenty of people stop in just for lunch and a soak, including Koyasan pilgrims who arrive the evening before to bathe and eat, then head up the mountain early the next morning. The ryokan picked up a couple of local tourism awards back in 2018.

A secluded ryokan deep in the mountains. It's not easy to get there, as the mountain road is very narrow. It's better to travel while it's still light. The water is quite interesting with a "soapy" film. Pleasant and relaxing. The rotenburo (outdoor bath) is surprisingly shallow and lacks the view you would expect from such a remote location. Recommended for a visit.

634. Yadori Onsen Iyashinoyu, Hashimoto, Wakayama Visited for day use at 700 yen. Day use available from 11:00 to 21:00 (Fri-Mon). They stamp the 88 Onsen of Wakayama stamp book. They sell the 12 Onsen of Wakayama stamp book. They issue Toreco cards for the onsen. Bath photos from the internet match roughly — I went in the evening and there was also an inflatable blue cold bath on the balcony. Very inconvenient to get to, especially by car in the evening. If there are several people, a shuttle is advertised on the website. 1. Indoor bath with clear water, slight cloudiness, soapy texture. Temperature 41.5. Breathing inside is fine. 2. Outdoor zone is essentially a balcony. Fence, basically no view. 2.1. Small round bath — couldn't get in, it was constantly occupied. Advertised temperature 40-42. 2.2. Inflatable blue cold bath. Very problematic to reach and the baths aren't impressive. 02.11.2025
