Aoni Onsen (Ranpu no Yado)
青荷温泉Aomori · Tohoku
A remote 'secret hot spring' deep in a forested valley in the Hakkōda foothills, reachable only by a single mountain road — the entire ryokan is lit by oil lamps at night (no electricity in guest areas), with four separate wood/rock baths fed by source-fed (kakenagashi) simple-spring water.
