Aizu Higashiyama Onsen Tsuruga Higashiyama Sohonzan

Tsuruga Higashiyama Sohonzan stands at the gateway to Higashiyama Onsen inside one of the three great wooden palaces of Aizu, a Showa-era mansion whose heavy post-and-beam joinery was laid by palace carpenters. When the building was refashioned as a one-group-per-day ryokan in 2022, it became something rare in Japanese hospitality: a private household available for one night at a time, with its snow garden, historic tea room, and irori dining hall entirely yours.

The butler meets guests at Aizuwakamatsu Station and drives to the property in a Mercedes bearing the registration 829, a Japanese phonetic tribute to basashi, the horse meat that will define the evening meal. Before the main rooms, the journey pauses at Meiseian, the property's historical tea pavilion, where matcha and seasonal confections are served facing a garden framed in bamboo. The ritual is unhurried: you arrive not to a reception desk but to an afternoon of ceremony.

Dinner is prepared at the irori by the head chef, who sources Aizu-certified horse meat from named local breeders and builds each course around the region's inland pantry. Kozuyu, preserved herring with sansho, and charred river fish cooked over open coals appear in sequence, with sake poured from the Suehiro brewery visited that afternoon. The circuit between landscape and table is closed within a single day.

The sodium-calcium sulfate-chloride waters of Higashiyama, drawn from a thermal spring with over thirteen centuries of continuous use, fill the open-air and indoor baths. With no other guests in the building, the rotenburo stands open at any hour: bamboo-framed mineral water in a stillness no booking system can manufacture.

The Royal Suite stretches across 169 square meters of layered history: tatami reception rooms and wide engawa corridors of Showa-era carpentry giving way to a bedroom with Scandinavian-modern furnishings and a working fireplace. The juxtaposition is candid rather than conflicted. The weight of genuine architecture is not diminished by a modern mattress.

On the morning of departure, the irori fire is lit one final time for grilled river fish and warm rice. Tea is poured beside the garden window, light reaching slowly across the tatami, with no other voice in the building.
