The Foundation of the Shrine and Its Early History
According to shrine tradition, Omiya Shrine was founded in 712, during the Nara period. Its origins are associated with the enshrinement of the spirit of Yamato Takeru, which was transferred from Atsuta Jingu in present-day Aichi Prefecture.
From that time onward, the shrine was revered as the Ubusunagami, or guardian deity of the local area. It became an important spiritual presence for the community, protecting the land and its people throughout the centuries.
History and Development
Kakuban and the Sanbu Gongen Tradition
During the late Heian period, the influential Buddhist monk Kogyo Daishi Kakuban descended from Mount Koya and established the foundations of Negoro-ji Temple. As part of the religious traditions of the time, various deities were enshrined as protectors of the Buddhist teachings.
As a result, Omiya Shrine came to be known as Sosha Gongen or Sanbu Gongen, reflecting the close relationship between Shinto and Buddhism that characterized Japanese religious culture for many centuries.
The shrine was also designated as a place of prayer by Emperor Toba. This elevated status helped the shrine prosper and attracted increasing numbers of worshippers and visitors.
War, Destruction, and Reconstruction
The shrine suffered a major setback in 1585, when Toyotomi Hideyoshi launched his campaign to subdue Kii Province. The shrine buildings and many of its treasures were destroyed by fire during the conflict.
The shrine was later rebuilt during the Edo period under the patronage of Tokugawa Yorinobu, lord of the Kishu Domain. The present shrine complex has inherited this history of reconstruction and preservation.
During the Meiji period, Omiya Shrine was designated as a village shrine, and in the Taisho period it was elevated to the status of a district shrine. These developments demonstrate the shrine’s continuing importance to the local community even as Japan entered the modern era.
Highlights of the Shrine Grounds
An Extensive Sacred Forest
The shrine grounds cover approximately 20,000 square meters and are surrounded by abundant greenery. The sacred forest creates a tranquil atmosphere and changes beautifully with the seasons.
Walking beneath the trees provides a welcome break from the bustle of everyday life. Spring greenery, summer foliage, autumn colors, and the quiet atmosphere of winter each offer a different experience of the shrine grounds.
Traditional Buildings and Shrine Architecture
The shrine complex contains a number of traditional structures, including the main sanctuary, kagura hall, offering hall, and bell tower. The main sanctuary features the elegant Nagare-zukuri architectural style, characterized by its graceful flowing roofline.
The roof is traditionally finished with hinoki cypress bark, giving the building a dignified appearance that blends naturally with the surrounding forest.
Several subsidiary shrines are also scattered throughout the grounds, including Ebisudaikokuten Shrine, Sumiyoshi Shrine, and Kasuga Shrine. Exploring these smaller sacred sites adds another dimension to a visit and offers an opportunity to discover the diverse traditions of Japanese shrine culture.
The Legendary Tama-zuka
One of the historic sites within the shrine grounds is known as Tama-zuka, or the “Jewel Mound.” According to local tradition, this is the place where Kakuban is said to have buried a precious jewel he received from Mount Shigi.
Stories such as this add a layer of mystery to the shrine and offer visitors a glimpse into the legends and religious traditions that have been passed down through generations.
Festivals and Local Cultural Traditions
The Fascinating Yomisashi Festival
The best-known festival held at Omiya Shrine is the Yomisashi Festival (Saisai Festival), held annually on the first Saturday of October.
The festival is divided into daytime and nighttime ceremonies. During the day, the event takes the form of an autumn festival offering prayers for an abundant harvest. At night, a solemn ritual associated with the historical confirmation of the shrine’s territory is performed.
One of the most striking parts of the nighttime ceremony is the procession of people dressed in white ceremonial clothing. Divided into eastern and western groups, they carry sacred sakaki branches toward the sacred site known as the otabisho, or temporary resting place of the deity.
These sakaki branches are regarded as sacred objects. In the past, they were considered so mysterious and powerful that directly looking at them was believed to bring bad fortune.
According to local tradition, the branches are also associated with healing. The eastern branch is traditionally believed to have benefits for illnesses affecting the upper body, while the western branch is associated with ailments affecting the lower body.
Living Traditions of the Local Community
During the festival, traditional performances such as lion dances and children’s ceremonial dances are dedicated to the shrine. Local residents come together to preserve these customs and pass them on to future generations.
Another traditional practice involves eating fish that were offered to the deities after the festival. Such customs provide a fascinating insight into the relationship between religious ceremonies, local communities, and everyday life in traditional Japan.
