The only place in Japan where every room overlooks an untouched natural waterfall.

Set on a mountainside a short distance from Ureshino’s hot spring town, this is the only property in Japan where all 22 rooms overlook an age-old, unnamed waterfall. To create a truly comfortable space facing the falls, every detail was refined—from materials, colors, and lighting to bed heights and the depth of the open-air baths. Throughout the property are pieces from the Nob Collection, gathered over decades. Ureshino soil, tea, and washi paper express the quiet simplicity of wabi. Every guest room is a suite with an open-air bath fed continuously by our own on-site hot spring. The two top-floor suites sit level with the top of the waterfall, looking down over its cascading waters. Our dining concept, SAGAISM, uses only ingredients from Saga Prefecture, while tea selections are overseen by tea master Shunichi Matsuo. From the hot spring water and tableware to the ingredients and every cup of tea, everything comes from Saga. Neither the waterfall nor the architecture could ever be recreated. This is a retreat where the stay itself becomes the reason for the journey.

Introduction of the Accommodation

Lobby

The only place in Japan with views of an untouched natural waterfall from every room.

A short distance from the Ureshino hot spring district, an unnamed waterfall flows quietly down a sheer rock face on a mountainside. It has been here for generations, untouched and without a name. Our inn takes its name from this waterfall. This is the only inn in Japan where guests can enjoy views of an untouched natural waterfall from all 22 rooms.

THE FALLS SUITE Ebony&Ivory (7th Floor)
【THE FALLS SUITE】 Ebony&Ivory (7th Floor)

Look down on the cascading waterfall from the same height as its crest. Two contrasting rooms, one black and one white. Both overlook the waterfall cascading in the center.

THE FALLS SUITE ORIGO (7th Floor)
【THE FALLS SUITE】 ORIGO (7th Floor)

Look down over the cascading waterfall from the same height as its crest. Open the 13-meter-wide window to let the sound of the falls and the breeze flow through the space, with its 4.2-meter-high ceiling.

TAKI SUITE (20 rooms in total)
【TAKI SUITE】(20 rooms in total)

Uninterrupted windows frame the view, with even the terrace railings made of glass. From both the bed and the bathtub, your gaze leads straight to the waterfall. All 22 rooms open toward the rock face.

Hot Springs & Sauna
Hot Springs & Sauna

The hot spring water comes from a private source on the property. It rises at 200 liters per minute from beneath Ureshino, renowned for its skin-beautifying waters. The water feeds the open-air and indoor baths in all 22 guest rooms. Every bath features free-flowing water directly from the source.

Sample meal
“SAGAISM”—Saga’s bounty, down to the last drop of seasoning.

From fish, meat, and vegetables to seasonings such as soy sauce and salt, and even the flour used in our cooking, every ingredient comes from Saga Prefecture. Bordered by the Genkai Sea, the Ariake Sea, and Imari Bay, Saga is also blessed with mountains. We craft each Japanese dish using only ingredients nurtured by this rich natural environment.

Sample meal
A dish unlike any other, crafted exclusively with ingredients from Saga Prefecture.

The first harvest heralds the season’s arrival, peak-season ingredients offer their richest flavors, and the last harvest captures the season’s lingering essence. Attuned to these subtle seasonal shifts, we bring out the best in each ingredient through slicing, simmering, grilling, steaming, and frying, enriched by the aroma of a wood fire.
