The cemetery features unique non-traditional monuments, including a memorial for coffee-loving termites and a space-themed marker dedicated to a Japanese aerospace company.
The path to the mausoleum crosses the Gobyō-bashi bridge, which is believed to mark the boundary between the mundane world and the sacred sanctuary.
Followers of Kōbō Daishi believe the master never passed away, and monks bring two daily meals to the mausoleum as part of a formal ritual.
The site hosts the 'Candle Festival' (Mantō-e) in early summer, where thousands of lanterns are lit along the forest paths.
Several centuries-old cedars, some estimated to be over 800 years old, provide the primary canopy for the entire cemetery.
The cemetery includes the 'Ase-kaki Jizo,' a statue said to sweat in order to absorb the pain and suffering of living beings.
Okuno-in is the mausoleum of Kōbō Daishi, the founder of Shingon Buddhism, and serves as the most sacred site on Mount Kōya. The cemetery stretches over two kilometers through a dense cedar forest, housing more than 200,000 tombstones and monuments. Many of these stones belong to historical figures, feudal lords, and monks, dating back over a thousand years. The path culminates at the Tōrō-dō (Lantern Hall), located directly in front of the founder's mausoleum. Shingon belief maintains that Kōbō Daishi is not dead but remains in eternal meditation, waiting for the arrival of Miroku Buddha. Over 10,000 lanterns are perpetually lit within the temple complex, sustained by continuous offerings. The site is a registered UNESCO World Heritage component as part of the Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.
