Okunoin is the site of the mausoleum of Kobo Daishi (also known as Kukai), the founder of Shingon Buddhism and one of the most revered persons in the religious history of Japan. Instead of having died, Kobo Daishi is believed to rest in eternal meditation as he awaits Miroku Nyorai (Maihreya), the Buddha of the Future, and provides relief to those who ask for salvation in the meantime. Okunoin is one of the most sacred places in Japan and a popular pilgrimage spot.
The Ichinohashi Bridge (first bridge) marks the traditional entrance to Okunoin, and visitors should bow to pay respect to Kobo Daishi before crossing it. Across the bridge starts Okunoin’s cemetery, the largest in Japan, with over 200,000 tombstones lining the almost two kilometer long approach to Kobo Daishi’s mausoleum. Wishing to be close to Kobo Daishi in death to receive salvation, many people, including prominent monks and feudal lords, have had their tombstones erected here over the centuries.
