Sazaedo Temple Overview
Perched on the slopes of Mt. Iimori in Aizu-Wakamatsu city, Fukushima prefecture, Sazaedo is the only wooden double-helix structure in the world. Officially known as Entsu Sansodo, this 16.5-meter-tall, three-story hexagonal Buddhist temple was built entirely from wood in 1796 under the direction of a monk named Ikudo. Its nickname comes from the turban shell (sazae in Japanese), which its spiraling form closely resembles.
What makes Sazaedo truly remarkable is its double-helix interior. Visitors follow a continuous one-way ramp that spirals upward, crosses a bridge at the top and then descends along a separate path — meaning you never encounter anyone walking in the opposite direction. This ingenious design was created so that worshippers could pray at 33 statues of Kannon (the bodhisattva of compassion) placed along the route, completing a miniature version of the Saigoku 33 Kannon Pilgrimage without the weeks of travel the real journey required. While the original Kannon statues were removed during the early Meiji period, the temple’s walls and ceilings still bear colorful senjafuda (paper stickers bearing visitors’ names) left by pilgrims of centuries past.
Best Times To Visit Sazaedo
Sazaedo is open year-round and offers a different atmosphere with each season. Spring brings cherry blossoms to the surrounding hillside, while autumn paints the area in vibrant reds and golds, making it particularly photogenic. Winter visitors may find a dusting of snow on the ancient wooden structure, adding a quiet, almost mystical quality. Summer is pleasant but can be warm, so an early morning visit is recommended.
