Koyasan: Sacred Center of Shingon Buddhism Founded by Kobo Daishi

Koyasan, spread across a mountain plateau at about 800 metres in northern Wakayama, is the sacred center of Shingon Buddhism, opened by the monk Kukai, known as Kobo Daishi, in 816. Ringed by eight peaks, the basin-like terrain resembles an opened lotus flower and has drawn faith as a holy place for more than twelve hundred years. In 2004 it was inscribed as a UNESCO World Heritage Site as part of the Sacred Sites and Pilgrimage Routes in the Kii Mountain Range, and it remains a mountain of prayer visited by many worshippers and pilgrims. More than one hundred temples gather on the mountain, so that the whole forms a single religious city.

The Two Great Sacred Sites: Danjo Garan and Okunoin

At the heart of Koyasan is Danjo Garan, the site Kukai first opened as the central training ground of Shingon Buddhism. The vivid vermilion Konpon Daito pagoda, about 48.5 metres tall, rises here, and a solemn space unfolds that expresses the Esoteric Buddhist view of the world in three dimensions. The other sacred site is Okunoin, where Kukai is believed to continue meditating. Along the roughly two-kilometre approach to his mausoleum, amid aged cedar groves, more than two hundred thousand tombstones and memorial towers for feudal warlords and historical figures line the path in a solemn, mystical atmosphere.

Vegetarian Cuisine and Morning Prayers at Temple Lodgings

A quintessential Koyasan experience is staying at a temple lodging, or shukubo. Many temples on the mountain accept guests, where you can touch the life of the monks and enjoy traditional vegetarian cuisine that uses no meat or fish. Early in the morning you can join the morning prayer service in the main hall, spending a cleansing moment amid the resonance of chanting and the taut air. Some lodgings also offer sutra copying and meditation, giving you a special time to quietly face yourself away from the rush of daily life.

Enjoying the Seasons

Because Koyasan sits at high elevation, the fresh green of early summer and the autumn foliage, usually late October to November, are especially beautiful and ideal for a visit. When the Okunoin approach turns to autumn color its solemnity deepens, and the cherry blossoms at Danjo Garan in spring are splendid too. The mountaintop is considerably cooler than the lowlands, so mornings and evenings can be chilly even in summer; bringing a layer is reassuring. In winter it is sometimes covered in snow, and the silent, snow-clad sacred ground is enchanting.
