Meigetsuso

On a gentle highland above the onsen town of Kaminoyama, roughly two hours and forty-five minutes from Tokyo by Shinkansen, Meigetsuso occupies some 4,000 tsubo of grounds overlooking the Zao massif. The property takes its name from the harvest moon that rises over the plateau on autumn evenings, and the inn has been operating at this Hayama address since the late 1990s, gradually developing a loyal following among guests who return not for novelty but for continuity.

The hallmark of a stay here is the nakai service. Staff maintain records of past guests and their rooms: one reviewer arriving for a fourth visit after twenty-six years found staff pulling the details of a previous room assignment from the inn's own records during the check-in conversation. Preceding dinner, guests visit SAKAGURA, a sake and wine cellar on the property, to select the evening's beverages with guidance from staff. On certain evenings, the KURA space hosts full-moon concerts, a seasonal ritual that offers no fixed repeat. Counter Dining Yu, where the head chef prepares courses in front of seated guests and narrates the provenance of each ingredient, offers a calibrated alternative to in-room kaiseki service.

The kitchen draws directly on the Yamagata supply chain. The chef visits the market personally before service, and the table reflects that discipline: Yamagata beef from the valley floor, Tsuyahime rice cultivated to a singular prefectural standard, mountain vegetables gathered across the brief highland season, and local sake matched to the progression of the meal. Dinner and breakfast both arrive in the room, on lacquerware chosen to the occasion, at a pace that treats the meal as the evening's main event.

The bathing at Meigetsuso is grounded in the property's own sodium-calcium sulfate spring, drawn at 64.5°C. The large public baths for men and women are lined with Aomori hiba cypress, a Tohoku timber whose grain and antiseptic properties have made it the material of choice for the region's most serious bathing spaces. Fifteen of the twenty guest rooms include their own semi-open-air hot spring baths, and two private rental baths outside the rooms serve couples and families on a first-come basis. The outdoor rotenburo is positioned with a sightline directly to the Zao range and reads clearly in every season.

The rooms are arranged as detached and semi-detached structures across the grounds, renovated in recent years toward a clean adult-resort aesthetic: dark interiors, a mix of tatami living areas and Western-configuration bedrooms in the suite categories, and terraces oriented toward the mountain or garden. The renovation brought genuine comfort at some cost to accumulated age; the inn does not carry the worn, atmospheric weight that the most demanding wabi-sabi registers require. The public spaces, including a library, a yoga room, and a manga corner, speak to a proprietorship that understands its guests stay more than a single night.

In autumn, when the Zao foothills shift from green to copper and the mountain air carries the first real chill of the year, the outdoor bath becomes the center of the stay. The sulfate water steams into cooling air, and the ridge appears and recedes through the mist while the yukata dries on the terrace rail.
