What is Bobata Onsen Yahata-ya

Bobata Onsen Yahata-ya is a historic hot spring ryokan nestled in the natural landscape of Fukushima Prefecture. Its design combines traditional Japanese style with contemporary architecture, providing guests with a sense of extraordinary immersion. The most striking feature is the floating stage set in the center of the vast atrium lobby, which is used for traditional performances and events. The atmosphere created here is described as stepping into “another world,” leaving a strong impression on both anime fans and regular visitors.


Common Features with the Infinity Castle

The Atrium and Floating Stage

In the Infinity Castle depicted in Demon Slayer, vast spaces and shifting floors dominate the design. The atrium lobby of Bobata Onsen Yahata-ya, with its expansive ceiling and central stage, captures this sense of endlessness. At night, the stage glows under carefully designed lighting, adding to the surreal and mystical feeling.

Fusion of Japanese and Modern Design

The ryokan’s interior integrates the warmth of wood and the softness of washi paper with the clean lines of contemporary architecture. This fusion of Japanese tradition and modernity mirrors the Infinity Castle’s sense of being both real and otherworldly, giving visitors a memorable sense of immersion.


Comparison with Okawaso

Another ryokan in Fukushima, Okawaso, is also famed for evoking the Infinity Castle. While both share the iconic atrium spaces and floating stages, they offer distinct atmospheres.
