Mount Koya, or Koya San, is one of Japan’s most sacred destinations, drawing visitors with its ancient temples, forested mountains and deep spiritual calm. Founded over a thousand years ago as the centre of Shingon Buddhism, Koya San is home to more than a hundred temples, many of which offer overnight stays with vegetarian temple cuisine and a chance to join early morning prayers.

The approach up the mountain is dramatic, winding through cedar forests and small villages before reaching the elevated plateau. The heart of the experience is Okunoin, a vast cemetery lined with mossy gravestones and towering trees, leading to the mausoleum of founder Kobo Daishi. Lantern-lit at night and misty in the morning, it feels otherworldly and peaceful—a place to reflect far from modern noise.

Wander through the main temple complex, Kongobuji, with its painted screens and intricate stone garden, or stroll quiet lanes between temple lodges where pilgrims and travellers share meals and stories. There’s a special rhythm to life on Koya San that invites you to slow down, breathe deep and experience the spiritual side of Japan.

The journey itself—by train, cable car and bus—is part of the adventure, revealing remote valleys and mountain vistas. Whether you’re interested in meditation, Buddhist culture or just want a tranquil escape from the city, Mount Koya is a memorable and restorative destination where Japan’s spiritual heart comes alive.
