VIDEO: Spectacle in the forest, Mount Kōya 高野山

Mount Kōya (高野山, Kōya-san) is a mountain in Wakayama prefecture to the south of Osaka. First settled in 819 by the monk Kūkai, Mt. Koya is primarily known as the headquarters of the Shingon sect of Japanese Buddhism. Located in an 800 m high valley amid the eight peaks of the mountain, the original monastery has grown into the town of Koya, featuring a university dedicated to religious studies and 120 temples, many of which offer lodging to pilgrims. The mountain is home to Okunoin (奥の院), the mausoleum of Kūkai, surrounded by the largest graveyard in Japan. Wiki

The shingon sect believe that Kukai is not dead but rather meditating. They bring him food every day and change his clothes. No-one except the highest monks are allowed to see him.

In 2004, UNESCO designated Mt. Koya, along with two other locations on the Kii Peninsula, as World Heritage Sites.
