Amihari Shinyu Spring

Sampled at wellhead
黄
Sulfur
Classification

Calcium Sulfate-Bicarbonate spring

A hot (72.9 °C), weakly acidic simple-sulfur spring of the hydrogen sulfide sub-type. Lightly mineralized at 0.199 g/kg of dissolved solids, but with 4.0 mg/kg of free H₂S it carries the unmistakable rotten-egg note that defines a sulfur bath. The water is gentle in body yet distinctly sulfurous — characteristic of the Hachimantai highlands above Amihari.

About

Yakushi-no-yu (薬師の湯), the day-use bath hall of Kyukamura Iwate Amihari Onsen (休暇村岩手網張温泉), sits a five-minute walk from the main hotel across a boardwalk and the Yunozawa suspension bridge. Each gender has one indoor bath and one rotenburo (open-air bath). The water is a milky sulfurous spring that whitens in the warmer months and clears toward winter, depending on snowmelt feeding the source. From the outdoor bath you can look out over rice paddies and the ridgeline of the Ou mountains. The building takes its name from a small shrine nearby, Amihari Yakushisha (網張薬師社). Hotel guests enter free; a footbath on the boardwalk between the buildings makes a good stop on the way.

Amihari Onsen, higaeri. Mildly acidic and sulfuric, pretty hot - brutal in summer. Lots of horseflies outside, have to swat them away. Excellent water, beautiful views, birch trees everywhere. There's also a campground here, with the trail up to Mt. Iwate starting nearby.
