One of Koyasan’s most distinguished structures is Kongobuji Temple, the head temple of Shingon Buddhism. The building’s natural toned facade stands in harmony with the tranquil environment and, inside, features elegant sliding doors that are painted with seasonal flowers and cranes. Take off your shoes and explore the peaceful corridors. Also located on Kongobuji’s grounds is Banryutei Rock Garden, which is Japan’s largest rock garden, containing over 100 large granite stones arranged to resemble two dragons.
Near Kongobuji is the Danjo Garan complex, which marks the center of the area and is the site of Kukai’s original temple. Walk through the temple grounds and observe the sacred structures, including the vermillion painted Konpon Daito Pagoda, which stands bright against the muted foliage.
Truly, Koyasan’s holiest place is its cemetery, Okunoin, which is home to Kukai’s mausoleum. The mystical area is marked by cobblestone paths that weave through moss covered gravestones and ancient cedar trees. Walk through over 1,000 years of history and envelope yourself in the overwhelming sense of peace. To witness the grounds at night, reserve a spot on the Okunoin Night Tour where a monk will guide you through the grounds by torchlight.
Given its religious significance, Koyasan is an ending point for multiple pilgrimage trails and is recognized as a UNESCO World Heritage site due to its inclusion in the “Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.” Trek through the tranquil woods on multi-day or day hikes, and journey the same sacred paths that countless others have done for centuries before.
Most famously, Koyasan is a part of the Kumano Kodo, which is a network of pilgrimage routes in the Kumano region located in southern Wakayama and Mie Prefectures. Koyasan is connected to Kumano via the Kohechi Trail. This multi-day, 70 km hike is a challenging journey through mountainous terrain and should only be attempted by experienced hikers with proper equipment.
Another scenic hiking route is the Choishi-michi, which is a 24 km trail from Jison-in Temple (near Kudoyama Station) to Koyasan. The forested path takes you through mountainscapes and small shrines and is marked by stone signposts (choishi), reminding you of the area’s sacredness. The entire hike takes about 6 to 7 hours, though you can shorten the journey by starting at trailheads closer to Koyasan.
A shorter, yet equally beautiful and impactful hike is the Fudozaka Trail, which starts at Gokurakubashi Station and ends at Fudozaka-guchi Nyonindo temple hall. This 2.5 km, roughly one hour trail is a perfect way to experience a traditional entrance to Koyasan.
The quickest and easiest way to get to Koyasan is via private lines. It is possible to reach Koyasan using some JR lines, but the travel time will be longer.
