Ōminesan-ji is an important temple of the Shugendō religion in Yoshino district, Nara prefecture, Japan. It is located at the peak of Mount Ōmine, or Sanjōgatake. According to tradition, it was founded by En no Ozunu, the founder of Shugendō, a form of mountain asceticism drawing from Buddhist and Shinto beliefs.
The sanctuary around the Sanjōgatake peak has long been considered sacred in Shugendō, and women are not allowed in the area beyond four "gates" on the route to the peak. On the neighboring Inamuragatake peak, altitude 1,726 m, it has been opened as a place of training for female believers since 1959, thus called "Women's Ōmine".
