Mount Oyama is home to the Afuri Shrine, historically divided into lower (shita) and upper (kami) shrines.
The mountain was formerly known as 'Amefuri-yama' (Rain-fall Mountain) because of the clouds that frequently gather around its peak.
It was a popular destination for Edo-period pilgrimage groups known as 'Oyama-ko', who would chant specific prayers while ascending.
The mountain's local specialty, the 'Oyama-koma' top, is said to have been carved by pilgrims as a souvenir.
The summit provides an unobstructed view of Mount Fuji, particularly visible during the winter months.
The ascent path is lined with traditional stone lanterns and Buddhist statues left by historical pilgrims.
The Oyama area is famous for its tofu cuisine, which developed historically to serve the needs of religious pilgrims.
The mountain features a dedicated 'Meoto-gi' or 'Married Couple Tree', a sacred cedar with two trunks joined together.
Mount Oyama is a 1,252-meter peak in the Tanzawa-Oyama Quasi-National Park known for its historical significance as a center of mountain worship. The mountain features the Afuri Shrine, which has been a pilgrimage destination since the Edo period. Visitors can access the lower reaches via a cable car that stops near the main shrine buildings. The trails range from paved stone paths near the base to rugged, forested terrain closer to the summit. It is famously associated with the 'Oyama-koma' spinning tops, a traditional local craft. Clear days offer panoramic views spanning the Kanto Plain and the Sagami Bay. The mountain slopes are notably densely covered in cedar and cypress forests. Various hiking courses cater to different fitness levels, with the main trail passing by the scenic Otowa Waterfall.
