Omoidenoyado Yunosimakan

At the far end of Prefectural Road 29, where the Abe River narrows between walls of cedar and maple at nearly 1,000 meters elevation, Yunosimakan has held a quiet position in the Umegashima valley since 1958. The inn is a family enterprise of the plainest description: one household that cooks, welcomes, lays futon, and opens the door, sustaining the same operation for over six decades in a mountain enclave that most of Japan has never heard of.

The four private baths are named for the characters of the Fuurinkazan, the battle banner of Takeda Shingen who kept this valley as one of his hidden retreats in the sixteenth century. The goemon iron tub (風, wind), the hinoki cypress enclosure (林, forest), the bath beside a glowing irori hearth (火, fire), and the retreat inside a cave cut from the hillside (山, mountain) each offer a radically different encounter with the same water. Guests collect a key from the front desk and hold the bath entirely to themselves. The spring is a simple alkaline sulfur water at pH 9.6, nationally designated as a therapeutic hot spring. It is silky rather than mineral-heavy, leaving the skin smooth and faintly warm long after you step out.

Dinner is built around Suruga chicken, a heritage breed raised on a green tea diet in the surrounding Shizuoka hills, arriving as hot pot with a closing ramen course in its own concentrated broth. Abe valley wasabi, harvested in cold mountain stream water a short distance upstream, runs through the meal from first plate to last. The cooking does not follow the ceremonial structure of metropolitan kaiseki; it follows the logic of the land.

Six rooms were renovated in 2023 to a Japanese modern sensibility, with solid timber furniture, hanging chairs at the windows, and a choice between futon and Japanese-style beds. The building sits directly above the river, and the sound of water carries through at night. Autumn arrives along the Abe valley road as a corridor of maple and cedar color; winter brings mountain silence and the particular pleasure of long baths in cold air. The guest reviews read less like travel reports than correspondence: one visitor on their sixth consecutive stay, another returning each January for five years in succession.

The cave bath at night holds the stay in a single image: water rising from volcanic rock, sulfur just present in the cool air above the surface, and the mountain perfectly still.
