What is Oyama Afuri Shrine?

Mount Oyama is located at the southwestern edge of the Kanto Plain and has been worshipped as a sacred mountain since ancient times. Due to its beautiful shape, it is affectionately known as “Sagami Oyama” or “Amefuri-yama” (Rain-Falling Mountain), and has a history of developing as a sacred site for mountain worship.

Oyama Afuri Shrine has a unique structure with three shrine buildings on the mountaintop.

History of Oyama Afuri Shrine
Founding and Ancient Beliefs
Oyama Afuri Shrine is said to have been founded approximately 2200 years ago during the reign of Emperor Sujin (around 97 BC to 30 BC). It is an ancient shrine listed in the “Engishiki Jinmyocho” (a list of shrines compiled in the Heian period) and has been positioned as an important center of faith in Sagami Province.
Since ancient times, Mt. Oyama has been revered as a sacred mountain for praying for rain and abundant harvests, and its alternative name, “Afuriyama” (Rain-Falling Mountain), originates from this belief. In agricultural societies, rain was a lifeline, and Oyama Afuri Shrine was widely worshipped as the god of water and rain.
The Era of Shinto-Buddhist Syncretism
From the medieval to the early modern period, Oyama Afuri Shrine was influenced by the syncretism of Shinto and Buddhism and was worshipped as “Oyama Sekison Daigongen.” It also flourished as a sacred site for Shugendo (mountain asceticism), and many ascetics visited it as a place for mountain training.
During the era of Ryobu Shinto, the two subsidiary shrines were called “Great Tengu” and “Little Tengu” as the sacred bodies of the main shrine, and were revered as a sacred site of the land, enshrined in the rocky depths and revered as a sacred place of the realm, with its roofs reaching high into Takamagahara (the High Plain of Heaven).
The “Oyama Pilgrimage” Boom in the Edo Period
During the Edo period, pilgrimages to Oyama Afuri Shrine became extremely popular among common people as “Oyama Pilgrimage.” It was particularly popular among the townspeople of Edo, and every summer, pilgrimage groups called “Oyama-ko” were organized, with records indicating that as many as 200,000 people visited annually.
“Oyama-mairi” was not merely an act of faith, but a major event encompassing elements of leisure and tourism. Pilgrims, clad in white robes, ascended the mountain while chanting “Rokkon Shojo” (purification of the six senses). At the foot of Mount Oyama, lodgings and tea houses lined the streets, creating a bustling temple town.
Changes after the Meiji Era
Due to the Meiji-era separation of Shinto and Buddhism, Oyama Afuri Shrine adopted a purely Shinto form, eliminating its Buddhist elements. However, the essence of its faith remained unchanged, and it continues to attract many pilgrims to this day.
In 2016, “Oyama Pilgrimage,” including the “Pilgrimage to Oyama,” was designated a Japan Heritage site as a place of faith and recreation for the common people of Edo, featuring the “Oyama Pilgrimage” with giant wooden swords, and its cultural value has been re-evaluated.
