A wooden inn at the end of a dark road, three floors of windows under the stars and a bath deep enough to stand in… At Fujisan Ryokan, everything grows upward, even the night!
Fuji without a mountain
We arrive after sunset. The forest has already swallowed the valley, the trees and the Toyosawa River. A few lanterns light the entrance while the facade hides behind the branches. No Mount Fuji on the horizon. Here, Fujisan is written 藤三, not 富士山. The inn stands in Namari Onsen, in the mountains of Hanamaki, in the south of Iwate Prefecture. It has this fold of the valley to itself, with the river for a neighbour and the forest all around. The last light before the woods is the front desk.
Three floors under the stars
Once through the door, you still have to look up. The main building, built in 1941, stacks three floors of zelkova wood above the river. Windows, galleries and gables pile up into a silhouette surprisingly tall for a mountain ryokan.
The hot spring water claims six centuries of history; the current building is younger, but it seems to have soaked up the rest. Since February 2026, the main building and the Shirozaru-no-yu bathhouse have been registered as Tangible Cultural Properties of Japan. The wood isn’t six hundred years old. The water almost is.
The white monkey got there first
According to legend, an ancestor of the Fujii family was working as a woodcutter at the foot of Mount Takakura when he saw a white monkey come out of a hollow in the rock. The animal was soaking its injured limbs in a spring that welled up at the foot of a katsura tree. A first hut is said to have been built around 1443 so the family could enjoy this water. In 1786, a larger building opened the bath to the public. The monkey then gave its name to Shirozaru-no-yu, the “white monkey bath”.
A bath with no shallow end
To reach Shirozaru-no-yu, you go down beneath the building. At the bottom, a vast stone room opens under a high ceiling. The large oval pool fills almost the whole space; the small round bath beside it looks like a full stop. The main pool was dug straight into the rock. Its average depth is about 1.25 metres, and the spring rises under your feet, from the very bottom of the bath. The water is neither piped in nor recirculated: here, the bath was built on top of the spring.
You walk in slowly, step after step, until the water rises up to your chest. Then you stay standing, almost weightless, in the middle of the room. Above, the windows and galleries make the depth feel even greater. You bathe in the basement while watching the building rise around you.
The room is somewhere
After the bath, you have to find your way back. Yukata tied tight, hair still damp, you head down a first corridor of dark wood. Red wall, black windows, a turquoise bench under neon lights: the inn suddenly looks like a Japanese guesthouse forgotten at the end of a railway line.
A few doors further on, the scenery changes. The wooden floor gives way to red carpet, the walls calm down and the rooms line up under the night lights. Fujisan Ryokan combines a historic building, a more comfortable annex and a wing set aside for tōji, the long hot-spring cure stays of the past. In that wing the rooms stay simple and guests can cook in a shared kitchen. Each corridor changes era before it changes floor. Miyazawa Kenji came here from childhood and mentioned the waters of Namari in Nametoko-yama no kuma. Later, the writer Tamiya Torahiko stayed more than a month in room 20, above the entrance, to write Ginshinjū. Somewhere behind these doors, literature spent the night too.
The night stays standing
Outside, the stars stay hooked above the roof. Inside, the wood creaks, the neon stretches the corridors and the spring keeps welling up under the empty bath.
We came to sleep in an old ryokan. What stays with us is a strange geometry: a facade climbing into the sky, a pool sinking into the rock and a room hidden at the end of a long red corridor. At Fujisan Ryokan, the night doesn’t lie down. It goes down to the basement and waits, standing, in the hot water.
