[2] Mount Ōyama has long been regarded as a holy mountain and object of worship.

At the top of the mountain is the head office of the Ōyama-Afuri Shrine (大山阿夫利神社, Ō-yama-afuri Jinja).

A narrow road runs directly between the town areas and the cable car station.

The Ōyama Mountain Climbing Marathon also takes place in March between Isehara Station and the lower shrine.
