Ogamiyama shrine boasts three "the best in Japan" features.
1. The longest stone-flagged approach to the shrine (700 meters).
2. The shrine is the largest gongen-zukuri in Japan, and designated as important cultural properties.
3. The lacquered sandalwood is the largest in Japan. There is also the biggest mikoshi (portable shrine) in western Japan.

Mt. Daisen was a training area for shugendo. Izumo fudoki (ancient records of the culture and geography of provinces of Japan) and Engishiki (a 927 AD Japanese book of laws and regulations) says that the need for a place to pray for shugendo monks was the beginning of Ogamiyama shrine, but details are unknown. Ogamiyama shrine and Daisenji had flourished, and more than 100 temples and 3,000 armed priests used to be under the control of the temple and shrine at the height of its prosperity.

Mt. Daisen Summer Opening Festival is held for 2 days in the first weekend of June. The festival is to celebrate the oncoming of summer to the mountain. At first night of the festival, more than 2,000 locals join the torch parade, and make a fantastic line at the stone-flagged approach of the Ogamiyama shrine. You are welcome to join the parade. A torch with a small gift is 500 yen on a first-come-first-served basis.
