About Mount Ōyama (Kanagawa)#
Mount Ōyama is a peak in Kanagawa Prefecture, Japan, known for its religious significance and mountain hiking; its summit reaches 1,252 metres. The mountain lies within the broader Tanzawa-Ōyama area and is a long-established site of pilgrimage.

A Shinto shrine, Ōyama Afuri Shrine, occupies the upper slopes and has been a destination for worship and mountain pilgrimage for many centuries. The site has long been used for religious observance and local mountain cult practices and remains an active shrine today.

- Elevation: Sits at an elevation of 1,252 metres, making it one of the higher peaks in Kanagawa Prefecture.
