Entsu Sankodo is a 16.5-meter-tall hexagonal three-story temple built in 1796 on Mt. Iimori in Aizuwakamatsu City, Fukushima Prefecture. This hall has a unique shape, and it has been known by the name "Sazaedo" because it resembles a turban shell. In the past, there were 33 Kannon statues here, but now they have been moved to another location. Crowds of people often come to worship, but thanks to its unique structure, with separate passages for going up and down, they can move safely without needing to push past each other. It is recognized for its unique place in the history of architecture, and in 1995 it was designated as a national important cultural property.
