Immortalized in Hiroshige's ukiyo-e woodblock prints, this 17th-century ryokan spreads across a 4,000-tsubo estate with six distinctive buildings overlooking wild, mossy gardens. The onsen here flows untouched—200 liters per minute of sulfur, sulfate, and bicarbonate waters that shift color with the weather. Families gather in the irori hearth room for shogi and karuta, while five private outdoor baths offer forest-view soaks in generous 1.6×1.8-meter tubs.
In Sengokuhara’s highlands, Kinnotake Sengokuhara frames Hakone as an adult ryokan of rare privacy: nine rooms only, each with its own open-air bath.

Chef Iwai’s Kyoto kaiseki is served in-room; afterward, The moon SPA and Bar Bamboo, facing a night-lit garden, keep the mood intimate.
Kinnotake Tōnosawa frames Hakone’s forested quiet through a creative ryokan concept inspired by Taketori Monogatari and Princess Kaguya.

Once the private retreat of the Imperial Family Kanin-no-miya, this ryokan occupies a privileged position within Hakone National Park, barely ninety minutes from Tokyo by rail.

A mineral pool surrounded by massive boulders anchors the gardens, while kaiseki dinners showcase seasonal local ingredients with quiet precision.

In Sengokuhara’s highland landscape, THE HIRAMATSU HOTELS & RESORTS SENGOKUHARA takes the form of a 20-room French-auberge retreat rather than a ryokan, with Western-style rooms and source-fed onsen baths in every room. Views reach Hakone’s mountains, greenery, the caldera, or, from some residence rooms, Mount Fuji; chef Suguru Urushibara’s Italian cooking, the SALON spa and Chagall-to-Kusama art suit food- and design-minded travelers.
A nine-storey contemporary reinterpretation of the ryokan tradition, this 150-room mountain retreat grants every guest a private open-air thermal bath fed by natural springs.

Forest trails wind past waterfalls to open-air yoga sessions, while family-friendly amenities—children's yukata robes, dedicated menus—welcome multigenerational groups.
Hoshino Resorts' Sengokuhara property channels the contemplative spirit of a traditional ryokan through an art-forward lens, with creative workshops and curated spaces designed to deepen guests' connection to nature.

Three natural hot springs cascade from volcanic rocks into outdoor pools at this spa set within the gardens of a former imperial villa. The mineral-rich waters, prized for their skin-nourishing properties, flow alongside sleek Japanese treatment rooms where restorative massages unfold amid the scent of exotic herbs. An indoor pool and Jacuzzi provide quieter moments between soaks in the open air.
Each area draws from different onsen sources. Gora offers sodium chloride springs known for warming the body, while Kowakidani features sulfur-rich waters. Yumoto, the oldest hot spring town at the base of the mountains, has the highest concentration of traditional ryokan with outdoor baths.
Autumn brings crimson maples from late October through mid-November, drawing crowds but offering spectacular scenery around Lake Ashi. Winter provides the clearest views of Mount Fuji and fewer visitors. The rainy season from June to July shrouds the mountains in atmospheric mist, creating an introspective mood that many Japanese travelers prefer.
Traditional ryokan follow centuries-old customs: kaiseki dinner served in-room, futon bedding laid out while you bathe, and yukata robes worn throughout the property. Most include two meals in their rates and structure the evening around bathing, dinner, and early rest. Many now blend these traditions with contemporary design and private onsen on the balcony.
Hakone spreads across the volcanic caldera of the Fuji-Hakone-Izu National Park, an hour from Tokyo yet a world apart. The town clusters into distinct areas: Gora with its modernist hotels and funicular railway, Sengokuhara's gallery-dotted plateau, and the shores of Lake Ashi where traditional ryokan have welcomed guests since the Edo period. Steam rises from natural vents, sulfur scents the mountain air, and the region's seventeen different hot spring sources each offer distinct mineral compositions prized for their therapeutic properties.
The dining landscape reflects this heritage of hospitality. Kaiseki restaurants along the old Tokaido road serve multi-course meals featuring local sansai mountain vegetables and Sagami Bay seafood. Gora's newer establishments pair Japanese craft with international technique, while teahouses scattered through the hills offer seasonal wagashi with views of Mount Fuji when the weather permits. Soba made from locally milled buckwheat remains a regional specialty, and several establishments have practiced the craft for generations.
