Classification

Sodium-Calcium Chloride spring

Oku-no-yu is an acidic sulfur-bearing sodium/calcium chloride spring (H₂S type). At pH 3.8 the water clouds milky white, with a tart edge and the unmistakable rotten-egg note of hydrogen sulfide. Generous metasilicic acid (94 mg/kg) layers in a faint silica softness behind the sharp, sulfurous bite.

About

Takinoya draws from four distinct springs at once: sulfur, salt, iron, and radium waters all flow fresh (kakenagashi, 源泉掛け流し) into the baths. The two large communal bath areas, Chien-no-yu (地縁の湯) in the basement and Kumoi-no-yu (雲井の湯) on the top floor, swap between men and women morning and evening, so guests get a different view each time. The outdoor baths look out over Noboribetsu's forest, and the water runs opaque and faintly sulfurous. Some rooms have their own private outdoor bath. Day use is not available; this is a ryokan stay.

Four different springs, all kakenagashi (free-flowing). Two on the upper floor, two on the lower floor. They alternate as shown in the photos below. On the upper floor, there is only a rotenburo (outdoor bath) with an endless pool overlooking the top of the hill and its forest with sakura: 1) Salty water with calcium 2) Sulfur water with potassium On the lower floor, there is a sauna, a mizuburo (cold water bath) with a view of the garden behind the ryokan. Baths inside and rotenburo: 3) Very sulfurous water (possibly with copper? Why else such a blue color?) 4) Sulfur water with iron I am a fan of "egg" baths, so this place is now at the top of my list 😄 Also, all the staff are warm and very responsive! Half of the rooms have their own private onsen with "egg" water. They also adapted the kaiseki meals perfectly to our vegetarian needs! We ate various types of tofu in many places, but here it was the most delicious!!! We could have eaten it forever)))) The European dishes were also very tasty: chocolate cake, panna cotta, salad dressing. We have never encountered such deliciousness even in Europe)))
