Fukushima Travel – Ashinomaki Onsen

Located in the scenic mountains of Aizuwakamatsu, Ashinomaki Onsen is one of Fukushima Prefecture’s most atmospheric hot spring towns.

Photographed in early December, the area was wrapped in pristine snowfall, transforming the riverside ryokan and surrounding cliffs into a tranquil winter wonderland. This is a destination where visitors can experience the quiet beauty of rural Japan, especially enchanting during the snowy season.

Ashinomaki Onsen has a long history as a healing hot spring resort, offering natural onsen baths sourced from deep underground. The town retains a nostalgic charm, with traditional inns lining the river gorge and seasonal scenery that changes dramatically throughout the year. In winter, snow-covered rooftops, steaming outdoor baths, and silent white landscapes create an unforgettable sense of calm and retreat.

Among the ryokan in Ashinomaki Onsen, Ōkawaso stands out as a destination in itself. In the evening, guests can enjoy a live shamisen performance in the dramatic, multi-level lobby. The sight of the performer playing traditional music against the backdrop of the grand wooden interior has become widely talked about for its resemblance to the Infinity Castle from the popular anime Demon Slayer: Kimetsu no Yaiba. This unique atmosphere has made Okawaso a viral sensation and a must-visit ryokan for both anime fans and cultural travelers.

Beyond its striking architecture, Okawaso also offers immersive cultural activities. Guests can participate in a samurai experience, where they learn proper sword etiquette, basic movements, and the spirit of the samurai that Aizu is historically famous for. This hands-on experience provides a deeper understanding of the region’s strong connection to samurai culture and bushidō traditions.

Visiting Ashinomaki Onsen in winter is especially rewarding. Soaking in an open-air hot spring while surrounded by snow, listening to the quiet flow of the river below, and later enjoying traditional performances creates a deeply memorable journey into Japan’s countryside.
