Ancient Origins and the Formation of the Shrine
The origins of Omiya Atsuta Shrine are believed to date back to ancient times. Originally, Azusamizu no Okami was enshrined on the summit of Mount Hongami, also known as Mount Nantai, at an elevation of 1,283 meters. The deity was revered as the guardian of the clear waters of the Azusa River, and the mountain itself became an important place of worship.
Later, the shrine was moved from the mountain summit to its present location at the foot of the mountain. A clean and sacred site was selected to make worship and religious ceremonies more accessible. At the same time, Atsuta no Okami was enshrined after being transferred from Atsuta Jingu in Nagoya, while Amaterasu Okami and Hachiman Okami, who had been worshipped at nearby shrines, were also enshrined together.
This gradually established the form of the shrine known today as Omiya Atsuta Shrine. In 1855, the shrine was officially given its present name and continued to serve as the principal guardian shrine of the local community.
A Magnificent Main Hall Preserving Muromachi-Period Architecture
The shrine’s main hall was constructed during the Muromachi period and follows the traditional ikken-sha nagare-zukuri architectural style. Its elegant yet powerful form features a gracefully curved kokerabuki wooden-shingle roof.
Fine craftsmanship can be seen throughout the structure, from the roof and supporting elements to the carefully finished decorative details. The building provides a valuable example of the architectural aesthetics of medieval Japan.
The main hall was designated a National Important Cultural Property in 1949 and is carefully preserved as one of the region’s important historic structures. The main hall of Wakamiya Hachimangu Shrine, located within the same grounds, was built around the same period and has also been designated a National Important Cultural Property.
A Giant Fir Tree and a Living Symbol of the Shrine
One of the most striking features of Omiya Atsuta Shrine is its enormous sacred fir tree. Rising approximately 43 meters high with a trunk circumference of about 6.3 meters, the tree is estimated to be around 600 years old. It is designated as a Nagano Prefectural Natural Monument.
The trunk remains free of major branches up to around 20 meters above the ground, giving the tree an exceptionally tall and powerful appearance. Higher up, more than ten substantial branches extend outward in different directions.
The sacred fir rises far above the surrounding cedar and cypress trees and can be recognized from a considerable distance. Standing alongside the historic shrine buildings, it serves as a remarkable living cultural heritage site symbolizing both the longevity of the shrine and the power of nature.

Spring Festival with Lion Dances and Floats
The shrine’s annual festival takes place every year on April 28 and 29. One of the highlights is the procession of colorful festival floats brought out by five local districts.
At the kagura hall within the shrine grounds, traditional lion dances are performed. Each of the five districts has its own distinctive style and customs, preserving variations of this traditional performing art that have been handed down through generations.
The festival is an important annual event for the local community. Along with expressing gratitude to the deities, it provides an opportunity to pass traditional performing arts and local customs on to future generations.
