The double-helix structure allows for a continuous one-way flow, which historically prevented overcrowding during peak pilgrimage times.
It is one of the few surviving examples of its architectural style in Japan.
The structure was designed so that the entrance and exit are located on different levels of the building.
The temple was originally constructed on top of Iimoriyama, but was moved to its current base location in the Meiji era.
The interior spiral path covers a total elevation change of approximately 16 meters.
Sazaedo is a 16.5-meter-tall wooden temple featuring a unique double-helix spiral ramp design that prevents visitors moving up from crossing paths with those descending. Constructed in 1796, this hexagonal structure was originally built to house thirty-three Kannon statues, allowing pilgrims to visit them in a single route. The building’s design is inspired by the structure of the turban shell, giving it its name, which translates to 'turban shell hall'. It is a designated Important Cultural Property of Japan. The interior lacks stairs, relying entirely on the gentle incline of the spiral walkway. It is located on the grounds of the former Iimoriyama hillside in Aizuwakamatsu. The temple is officially named Entsu Sanso-do.

Walk the spiral path slowly to fully appreciate the ingenious engineering of the overlapping ramps.
Visit the surrounding Iimoriyama area to see the burial site of the Byakkotai, a group of young samurai.
Wear comfortable, flat shoes as the entire temple is traversed via an inclined wooden floor.
Do not attempt to walk back down the same path you ascended, as the layout is strictly one-way.
Remove shoes before entering the wooden structure.
