Koyasan, high in the forested mountains of northern Wakayama, is the spiritual heart of Shingon Buddhism and one of Japan’s most extraordinary places to visit. Founded in 816 by the monk Kukai — posthumously Kobo Daishi — as a remote monastic retreat, the mountaintop basin now holds a whole town of around 100 temples, a World Heritage Site where daily monastic life continues much as it has for twelve centuries. Visitors come to walk the vast cedar-shaded cemetery of Okunoin, see the great halls of the Danjo Garan and Kongobu-ji, and above all to stay overnight in a temple lodging, joining the monks for vegetarian cuisine and dawn prayers.

Tips
Stay overnight if you possibly can — Koyasan transforms after the day trippers leave, and a shukubo temple stay with shojin ryori dinner and morning prayers is the whole point of coming. Pack warm layers whatever the season, as the mountain sits at over 800 metres and is markedly colder than the coast; the Koyasan World Heritage Ticket bundles transport and temple entries at a good saving.
