One of the most sacred sites in Japan, Koya-san is the heart of Shingon Buddhism, founded by the monk Kukai (posthumously known as Kobo Dashi) in the year 805. There is a secluded temple complex on the forest-covered mountain including his final resting place in Okunoin cemetery. The mountain is also the final spot on the Shikoku Pilgrimage and a popular spot for temple stays and traditional Buddhist cuisine.
