Ōmiwa Shrine, located in Sakurai City in Nara Prefecture, is a historic Shinto shrine centered on the worship of Mount Miwa. Rather than enshrining a deity within a main sanctuary building, the shrine venerates the mountain itself as the sacred object of worship, reflecting an early form of Shinto belief.

The shrine is associated with Ōmononushi no Ōkami, a deity appearing in early chronicles such as the Kojiki and Nihon Shoki. Its origins are considered to date back to ancient times, and the site has long been connected to prayers for agriculture, brewing, and protection from illness. The approach to the shrine leads through a forested area at the foot of Mount Miwa, preserving a natural and spiritual setting.

Ōmiwa Shrine offers insight into early Japanese religious practices, where nature and worship are closely intertwined. Its setting and traditions continue to reflect the continuity of Shinto belief from ancient times to the present.
