An Important Purification Site on the Tonda River
Inabane Oji is located near the Tonda River, which was historically an important place for mizugori, a ritual purification performed with water.
In traditional Japanese religious practice, pilgrims would cleanse themselves in the river before continuing toward Kumano Hongu Taisha Grand Shrine. This purification was an important part of the pilgrimage, symbolizing the cleansing of the body and spirit before entering the sacred realm of Kumano.
According to tradition, pilgrims arriving at Inabane Oji would dismount from their horses and perform mizugori in the Tonda River. After completing the purification ritual, they would cross the river and proceed toward Ichinose Oji on the opposite bank.
This tradition illustrates how the Kumano pilgrimage was not simply a long-distance journey. For medieval pilgrims, every stage of the route had a religious meaning, and purification rituals such as this helped prepare them for their approach to the sacred shrines of Kumano.
Today, the sound of the river and the surrounding mountains create a tranquil atmosphere. Visitors walking the Kumano Kodo can pause here and experience the same natural landscape that accompanied pilgrims many centuries ago.
A Shrine Recorded in Medieval Documents
Inabane Oji has a long history, and its name appears in records dating back to the Heian period.
The earliest known written reference is found in the diary Chūyūki by Fujiwara no Munetada. An entry from 1109 records the shrine under the name “Inahane Oji Shrine.” This provides valuable evidence of the shrine’s importance more than 900 years ago.
The shrine is also mentioned in historical records associated with imperial pilgrimages to Kumano, including the Kumano Gokōki, as well as the Kumano Engi and Kumano Mōde Nikki. These records demonstrate that Inabane Oji continued to receive special reverence throughout the medieval period.
Among the many Oji shrines along the Kumano pilgrimage routes, the Five Oji held a particularly prestigious status. Inabane Oji was therefore an important spiritual landmark for pilgrims traveling through the Nakahechi region.
A Shrine Closely Associated with Inari Worship
One of the most fascinating aspects of Inabane Oji is its connection with Inari worship, the Japanese tradition associated with rice cultivation, agriculture, prosperity, and abundant harvests.
In the Kumano Honji Mandala, the deity associated with Inabane Oji is depicted as an old man carrying rice. Because of this imagery, the shrine was also known as Inari Oji.
The shrine’s deity was believed to be Kongō Dōji in the form of an Inari deity. This association gave the shrine a strong connection with agricultural faith and prayers for fertility and abundant harvests.
The surrounding region has traditionally depended heavily on agriculture, making this aspect of the shrine’s religious identity especially meaningful to local communities.
A Legendary Encounter with the Inari Elder
Another fascinating tradition is recorded in the Nijūnisha Chūshiki. According to one legend, Inabane Oji was the place where the Tendai Buddhist monk Enchin first encountered the mysterious Inari Elder.
Such stories reflect the complex religious traditions that developed around Kumano, where Shinto beliefs, Buddhist teachings, pilgrimage traditions, and local legends became deeply intertwined.
Faith Preserved from the Edo Period to the Present
During the Edo period, Inabane Oji was revered as the ubusunagami, or guardian deity of the local community of Iwata Village.
Historical records indicate that the shrine’s main sanctuary was relatively small, measuring only about one ken square. Despite its modest size, it was carefully maintained and deeply respected by the local population.
In 1915, during the Taisho period, Inabane Oji was enshrined together with Iwata Shrine, and the original shrine building was relocated the following year.
For many years, there was no shrine building at the original site. In 1956, however, the deity was divided and a sacred spirit was returned to the former site, allowing Inabane Oji to be restored in its present form.
Today, the shrine stands quietly surrounded by trees, continuing its role as a place of prayer for people traveling along the Kumano Kodo.
A Valuable Example of Traditional Shrine Architecture
The former main sanctuary of Inabane Oji is now preserved at Iwata Shrine. The building is believed to date from the early 18th century and features a traditional architectural style known as ikken-sha sumigi-iri Kasuga-zukuri.
This style is characterized by a compact single-bay sanctuary and distinctive roof construction. The building provides an important example of the architectural traditions associated with Oji shrines and offers valuable insight into the history of the Kumano faith.
The site of Inabane Oji was designated a Wakayama Prefectural Historic Site in 1958. It is also protected today as part of the Kumano Pilgrimage Routes, inscribed on the UNESCO World Heritage List.
A Peaceful Stop on the Kumano Kodo
The area surrounding Inabane Oji is blessed with beautiful natural scenery. The landscape changes throughout the year, from fresh greenery in spring and deep green forests in summer to colorful foliage in autumn and crisp, clear air in winter.
Walking the Kumano Kodo here offers a special sense of connection with the past. Travelers can follow paths that were once walked by pilgrims centuries ago while experiencing many of the same mountains, forests, and rivers.
The scenery around the Tonda River is particularly peaceful. Taking a moment to listen to the flowing water and look across the surrounding landscape can provide a welcome opportunity to slow down during a pilgrimage or hiking journey.
Experience the Spiritual Heritage of Kumano
Inabane Oji is an important historical site for understanding the traditions of the Kumano pilgrimage. Its status as one of the Five Oji, its role as a purification site on the Tonda River, its connections with Inari worship, and its long history of local devotion all contribute to its unique character.
For visitors walking the Kumano Kodo Nakahechi Route, a stop at Inabane Oji provides more than a chance to admire a historic shrine. It is an opportunity to reflect on the beliefs, rituals, and landscapes that shaped the pilgrimage for generations.
Surrounded by nature and steeped in centuries of history, Inabane Oji offers a quiet and meaningful experience for anyone wishing to discover the spiritual heritage of the Kumano region.
