Tendō's premier hot spring destination offers fifteen rooms, each equipped with a private thermal bath—a rarity even among Japan's finest ryokan. Seven detached hanare cottages echo traditional tea ceremony architecture, while main-house accommodations lean contemporary. The evening kaiseki ritual centers on grilled eel, served alongside seasonal preparations. A communal onsen complements the private soaking options, making this an ideal retreat for families seeking authentic thermal culture.

Chef Makoto Harada runs this three-room adults-only retreat in Yamagata's Okitama Valley, where his Italian restaurant showcases housemade pasta and dry-aged Yonezawa beef shaped by the region's mountain air and dramatic temperature shifts. Rooms look out over open fields; one suite includes a private Finnish sauna. Onsen facilities complete the offering. Two and a half hours from Tokyo, the pace here slows deliberately.

Behind a decorative thatched-roof gate, this centuries-old structure—built to withstand Yamagata's heavy snowfall—surprises with Nordic-inflected minimalism: Arne Jacobsen Swan chairs face picture windows, while Tendo Mokko pieces furnish the 19 rooms spread across the main house and a converted storehouse. Each accommodation, finished in pale wood and white, features a private open-air bath fed by natural hot springs and tended by dedicated attendants.
