Mount Yuga as a Natural Landmark
Overview of Yugasan
Mount Yuga lies among the hills in the northern part of Kojima, Kurashiki City, and rises to an elevation of 274 meters. Located near the center of the Kojima Peninsula, it is surrounded by natural woodland and has long been regarded as a sacred place associated with worship of sacred rocks and mountain deities. Its formal name, Yugasan, is commonly used on maps, although the name Yuga-san is more widely used in everyday life.
The mountain’s wooded landscape and religious heritage make it an important part of Setonaikai National Park. Its natural surroundings provide a peaceful setting for visitors exploring the area’s temples, shrines, and traditional pilgrimage routes.
History and Religious Origins
The history of Mount Yuga dates back to the Nara period (710–794). In 733, during the Tenpyō era, the Buddhist priest Gyōki is said to have enshrined Amida Nyorai, the Buddha of Infinite Light, and Yakushi Nyorai, the Buddha of Medicine, together as Yuga Daigongen. Religious buildings were established on the mountain to honor these deities.
Yuga Daigongen became known as one of Japan’s Three Great Gongen, a group of prominent manifestations of Buddhist deities associated with Japanese religious traditions. This long history has given Mount Yuga considerable spiritual and cultural significance.
Temples and Shrines of Mount Yuga
Rendaiji Temple and Yuga Jinja Hongu Shrine
Today, the name Mount Yuga commonly refers to the area encompassing Rendaiji Temple and Yuga Jinja Hongu Shrine. The area is renowned as a major center of worship for Yuga Daigongen and for prayers seeking protection from misfortune. Its religious traditions are said to span more than 2,000 years.
Rendaiji Temple is traditionally believed to have been founded by Gyōki in 733 under the patronage of Emperor Shōmu. It was later revived in the early Muromachi period (1336–1573) by the eminent Buddhist monk Zōun. During the Edo period (1603–1868), the temple became an important place of prayer for the Ikeda family, the lords of Okayama Domain, who regularly visited to offer prayers.
The Separation of Buddhism and Shinto
Mount Yuga originally developed as a place where Buddhist and Shinto traditions were practiced together. However, following the Meiji government’s policy of separating Buddhism and Shinto in the late 19th century, Rendaiji Temple and Yuga Shrine became separate institutions. The shrine later adopted the name Yuga Jinja Hongu.
After World War II, the dissolution of State Shinto left the temple and shrine formally separate as religious corporations. In practice, however, they often continued to operate in close association, and prayers were conducted in ways that retained elements of the religious traditions that had existed before the Meiji period.
Modern Developments and Division
In 1998, a serious dispute arose between the brothers who were serving as the temple’s chief priest and the shrine’s head priest. The shrine took control of the buildings associated with its Shinto worship and began operating independently as a religious corporation. Relations between the two institutions subsequently deteriorated, and the dispute led to legal proceedings.
Although visitors still commonly refer to both institutions collectively as Mount Yuga, the two organizations have become separate in their operations. Even shared use of parking facilities has been restricted. Their complicated relationship remains part of the area’s modern history.
The Traditional Pilgrimage Town
Historic Streets Along the Approach
A traditional temple and shrine town developed along the approach to Mount Yuga to welcome pilgrims. The surrounding settlement is also commonly called Yuga and retains much of the atmosphere of its former days as a busy religious destination.
Many shops along the approach are generally closed outside peak pilgrimage periods, opening mainly during busy times such as the New Year holidays. The street includes restaurants, souvenir shops, and a post office, with residential buildings farther along the route. Numerous old structures remain, and efforts have been made to preserve the historic streetscape and protect the area’s traditional appearance.
Local Specialties and Hot Springs
One of Mount Yuga’s traditional specialties is ankoro mochi, a sweet made from rice cakes covered with sweet red bean paste. Yuga Onsen, a short distance from the main religious area, offers visitors a relaxing place to unwind after sightseeing and prayer.
In the past, pilgrims often visited both Mount Yuga and Kotohira-gū Shrine in Sanuki Province, present-day Kagawa Prefecture. This custom was known as ryōmairi, or making a paired pilgrimage to both sacred sites. Tanokuchi Port, located at the southern foot of Mount Yuga, flourished as the nearest port for pilgrims. Nearby districts, including Tanokuchi, Karakoto, and Shimonomachi, also developed as lively gateway settlements serving visitors to the mountain.
The Yuga District and Its Development
Historical Background
The Yuga district was once known as Yamamura and, together with the neighboring Shirao district to the south, belonged to Kojima County. Over time, it was transferred to Tanokuchi Village and later incorporated into Kotoura Town. Today, the area forms part of Kojima-Yuga in Kurashiki City.
The district’s development is closely connected with the establishment of Rendaiji Temple. During the Edo period, the area was part of Okayama Domain. Following the abolition of the feudal domains in the Meiji era, it became part of Kojima County in Okayama Prefecture.
Facilities in the Area
In addition to Rendaiji Temple and Yuga Jinja Hongu Shrine, the district is home to facilities such as Yuga Youth Nature House and Kurashiki Yuga Onsen Hotel Santoka. Educational institutions, including Kurashiki Municipal Kotoura-kita Elementary School and Kotoura-kita Kindergarten, also serve the local community.
A Sacred Destination Surrounded by Nature
Mount Yuga brings together a distinctive natural landscape, centuries of religious tradition, and a historic pilgrimage settlement. It continues to attract local residents, worshippers, and travelers interested in the spiritual heritage of Okayama. Preserving its historic buildings, cultural traditions, and natural environment will help ensure that this distinctive destination remains an important part of the region’s heritage for generations to come.
