Tateriko Shrine

Tateriko Shrine is located in Yoshio District in the Southern Nara Prefecture. The shrine, whose official name is Kojin Shrine, stands on top of a 1,260-meter-high Kojin Mountain, past an "out of this world" line of wooden torii gates that leads to the main hall. The shrine is located in the middle of Mount Koya, a training site for Shingon Buddhism Mikkyo, and is one of Japan’s Three Greatest Kojin Shrines.
Tateriko Shrine opened around the 9th century. Its origin can be traced back to when Kukai (Kobo Taishi), the founder of Shingon Buddhism Mikkyo, drew a picture of Sanpo Kojin (a guardian god of Buddhism) on a board, enshrined it in the region of the Old Kojin and built the Great Garan (a spiritual place where monks gather for training) so that Mikkyo would prosper and be protected. It originally enshrined only Sanpo Kojin, but since the movement to abolish Buddhism in the Meiji era, it has enshrined Hondawakenomikoto and Honmusubinokami.
Mount Kojin is known as a great spot to see a sea of clouds. In the best conditions, you can see the fanciful scenery of the sun rising from a sea of clouds.
