Mount Koya (高野山, Kōyasan) is the center of Shingon Buddhism, an important Buddhist sect which was introduced to Japan in 805 by Kobo Daishi (also known as Kukai), one of Japan’s most significant religious figures. A small, secluded temple town has developed around the sect’s headquarters that Kobo Daishi built on Koyasan’s wooded mountaintop. It is also the site of Kobo Daishi’s mausoleum and the start and end point of the Shikoku 88 Temple Pilgrimage.
Kobo Daishi began construction on the original Garan temple complex in 826 after wandering the country for years in search of a suitable place to center his religion. Since then over one hundred temples have sprung up along the streets of Koyasan. The most important among them are Kongobuji, the head temple of Shingon Buddhism, and Okunoin, the site of Kobo Daishi’s mausoleum.
Koyasan is also one of the best places to experience an overnight stay at a temple lodging (shukubo) where you can get a taste of a monk’s lifestyle, eating vegetarian monk’s cuisine (shojin ryori) and attending the morning prayers. Around fifty temples offer this service to both pilgrims and visitors.
