Mount Kōya, or Kōyasan, was first settled in 819AD by the legendary monk Kūkai, also known as Kōbō Daishi, who introduced esoteric Shingon Buddhism to Japan after studying in China. Nestled in a secluded alpine basin surrounded by eight lotus-like peaks, this sacred site in Wakayama Prefecture was chosen for its geomantic significance and spiritual isolation. By imperial decree in 816, Kūkai began transforming the mountaintop into a monastic haven. Over time, Kōyasan evolved into the world headquarters of the Shingon sect and remains one of the holiest destinations in Japanese Buddhism. The monk’s legacy still permeates the air, carried on by generations of acolytes who walk his path, both physically and metaphysically.

Today, Kōyasan is home to 117 temples, remnants of the over 2000 that once thrived during the Edo period. At the heart of this spiritual city stands Kongobu-ji, the principal Shingon temple, with its elaborate sliding door paintings and rock garden, the largest in Japan. Nearby, Danjogaran serves as the ritual centre, its crimson Konpon Daitō pagoda a blazing icon of esoteric architecture, modeled after mandalas brought back by Kūkai. The Kongosammai-in temple, more humble in scale but rich in spiritual gravity, holds the oldest surviving esoteric pagoda in Japan, an enduring testament to medieval religious artistry and ritual practice.

Beyond the structures and ceremonies lies Okuno-in Cemetery, the spiritual heart of Mount Kōya. Here, beneath towering cedar trees older than empires, more than 200000 gravestones and memorials line the path to the mausoleum of Kūkai, who is believed to rest in eternal meditation, awaiting the future Buddha, Maitreya. Samurai, poets, feudal lords and even modern corporations have erected tombs here, believing proximity to the great master offers karmic merit. Lanterns flicker along the trail like ghost lights, as pilgrims whisper sutras in reverence. The boundary between the living and the dead thins with each step and it is said that no one leaves Okuno-in unchanged.

Yet Kōyasan is not just a centre of piety but a place wrapped in shadows and whispered legends. One tells of a wandering monk who desecrated a sacred relic and vanished in the forest, only to be found years later, mummified in meditation, his eyes wide open. Another tale speaks of night spirits who guard the graves at Okuno-in, punishing those who stray from the path with an eternal curse of lost time. Locals whisper that during certain nights, when the moon is high and the mist clings low, Kūkai’s chanting can still be heard echoing through the groves, as if time has folded upon itself.

Historically, Kōyasan has withstood centuries of turmoil, from civil wars to government crackdowns on Buddhism during the Meiji Restoration. The monks adapted, preserving their teachings through secret rites and encoded scriptures. During the Edo period, shoguns often retreated here seeking spiritual protection and guidance, establishing tombs and commissioning ornate halls. Even during the Second World War, the mountain remained untouched, its temples offering refuge to those fleeing bombed cities, its forests swallowing secrets that remain buried to this day.

In 2004, UNESCO enshrined Mount Kōya and its network of pilgrimage trails into Kyoto and Nara as a World Heritage Site. These paths are more than physical routes, they are metaphysical journeys through ascetic devotion, bound tightly with Japan’s natural and supernatural landscapes. To walk them is to trace the very heartbeat of spiritual Japan, through mist, moss, and memory, where the divine, the spectral and the historical converge in one timeless, breathing sanctuary.
