The vermilion Konpon Daito Pagoda, a 45 meter tall, two tiered, tahoto style pagoda. A statue of the Dainichi Nyorai (Cosmic Buddha, also known as Variocana), the central Buddha in Shingon Buddhism, stands in the middle of the pagoda's interior and is surrounded by statues and paintings on pillars, which together make up a rare three dimensional mandala (a metaphysical map of the cosmos). Mandala are usually two dimensional paintings.

Okunoin (奥の院) 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.

Legend has it that Kobo Daishi, the founder of Shingon Buddhism, threw his sankosho (a double ended, three pronged Buddhist ceremonial tool) from China, where he had been studying, toward Japan. Back in Japan, while in search of a place to headquarter his new religion, he came across his sankosho stuck in the branches of a pine tree on Koyasan and started construction of the Garan, Koyasan's central temple complex. The pine tree, that caught the sankosho, is still growing there. The two most prominent buildings of the Garan are the Kondo Hall and the huge Konpon Daito Pagoda. The Kondo Hall is a large wooden temple hall where major ceremonies are held. The building has burned down multiple times over the centuries, and the current hall dates back to 1932. It enshrines an image of Yakushi Nyorai, the Buddha of medicine and healing.
