Located in Aizuwakamatsu City, Fukushima Prefecture, the "Sazae-do"—officially called Entsu Sansodo—is a wooden structure built in 1796. What sets it apart is its unique double-helix design inside, where the upward and downward pathways are completely separate. This innovative structure allows visitors to complete their pilgrimage without retracing their steps, a feature that is rare even on a global scale. Recognized as an Important Cultural Property of Japan, Sazae-do attracts numerous visitors who come to experience its rich history and distinctive architecture.
