History and Religious Traditions of Yuga Shrine Hongu
Mount Yuga as a Sacred Site
Mount Yuga has been revered since ancient times as a place of worship centered on sacred rocks and mountain spirituality. In 733, the Buddhist monk Gyōki is said to have enshrined an Eleven-Headed Kannon at the site. Over time, the mountain developed into a center of syncretic worship known as Yuga Daigongen, where Buddhist and Shinto traditions were practiced together.
According to the historical account associated with nearby Kumano Shrine on the northern foothills, five senior disciples of En no Gyōja brought a sacred object from Kumano Hongu Taisha in Kii Province to this region in the early Nara period. They established Kumano Shrine here, and a sanctuary dedicated to Nachi was later built on Mount Yuga as part of a local counterpart to the Three Kumano Shrines.
Prosperity During the Edo Period
By the middle of the Edo period (1603–1868), Yuga Shrine had become an important place of prayer for the Ikeda family, rulers of the Bizen Domain. The domain lords visited the shrine three times a year, in January, May, and September, and sponsored construction and renovation work on the shrine buildings and the guest quarters of nearby Rendai-ji Temple. This patronage helped establish Yuga as a major center of regional worship.
Separation of Shinto and Buddhism
During the Meiji period, government policies separating Shinto and Buddhism led to the formal separation of Yuga Shrine and Rendai-ji Temple. Yuga Shrine subsequently developed a network of 52 subsidiary shrines across Japan, particularly in western Japan.
After World War II, the dissolution of State Shinto left the shrine and temple formally separate. In practice, however, they continued to operate closely together, with Buddhist clergy conducting prayers in the main shrine building. Their religious activities therefore retained aspects of the unified traditions that had existed before the Meiji reforms.
Modern Conflict Between the Shrine and Temple
On March 3, 1997, Yuga Shrine took possession of some of the buildings and began conducting its religious activities independently as a religious corporation. The dispute is said to have stemmed from a conflict between the brothers who served as the temple’s chief priest and the shrine’s head priest. Relations between Rendai-ji Temple and Yuga Shrine deteriorated from that point onward, leading to legal proceedings, including a lawsuit by the temple seeking the return of the buildings. Despite the dispute, Yuga Shrine has continued its independent religious activities.
The Tradition of Visiting Both Yuga and Konpira
During the Edo period, a custom known as ryōmairi, or “visiting both,” became popular. Worshippers visited both Yuga Daigongen at Yuga-san Rendai-ji Temple and Konpira Daigongen at Konkō-in Matsuo-ji Temple in Sanuki Province, now Kagawa Prefecture.
This tradition brought prosperity to the Tanokuchi area south of Mount Yuga, which developed into a lively town serving pilgrims on their way to the mountain. The custom reflects the long-standing connections between religious sites on opposite sides of the Seto Inland Sea.
