Koya San, Japan

Twice every day, monks carry a meal to the mausoleum of Kukai at the end of the Okunoin cemetery path. They have been doing this without interruption since 835 CE. Kukai, the monk who founded Shingon Buddhism’s headquarters on this mountain plateau in 816, is understood within the sect to be in a state of eternal meditation rather than dead. The practice is not ceremonial. In the logic of the place, the man in the mausoleum is hungry.

Understanding this before you visit Koyasan changes what you see there. It is not a historical site. It is a functioning religious community of roughly 3,600 residents, about 50 temples, and a tradition that has been continuous for twelve hundred years.

Getting There

From Osaka Namba station, take the Nankai Koya Line to Gokurakubashi (about 1.5 hours on express trains), then the cable car five minutes up to the mountain plateau. The World Heritage Ticket (around JPY 3,400 from Namba) covers the cable car and unlimited bus travel on the mountain; the key sites are spread across the plateau and the bus saves considerable walking. Arrive at your temple lodging by 5pm; dinner is typically served at 5:30 or 6pm.

Okunoin

The 2-kilometre path to Kukai’s mausoleum passes through over 200,000 tombstones and memorial lanterns, the oldest dating to the Heian period. The cedar trees are enormous; some trunks are several metres in circumference. Moss covers every surface. The light through the canopy is specific to this forest because the trees are tall enough to make a complete ceiling.

Photography is not permitted beyond the Gobyobashi Bridge that marks the mausoleum approach, and silence is expected. The Toro-do (Lantern Hall) beside the mausoleum contains several thousand lanterns burning continuously, including two that have been alight since the 11th century. Walk it after dark if you can; when the lanterns are the primary light source and the path is quiet, the experience is substantially different from the daytime version. Both are worth doing.

Okunoin also contains the company graves of major Japanese corporations that have acquired memorial stones near Kukai’s mausoleum for their employees: Nissan, Panasonic, and others. It is the most specifically Japanese phenomenon at a site full of specifically Japanese phenomena.

Kongobu-ji and Danjo Garan

Kongobu-ji is the head temple of the Koyasan Shingon sect. The Banryutei rock garden, 2,340 square metres, is the largest rock garden in Japan: 2,340 stones arranged to represent two dragons emerging from clouds. Entry JPY 1,000. The Ohiroma hall has fusuma paintings by Kano school artists from the 16th and 17th centuries.

The Garan is the central precinct Kukai designed, with the Konpon Daito (Great Stupa) as its centrepiece: 48 metres tall, painted vermilion. The Fudo-do hall, dated to 1197, is the oldest surviving building on Koyasan and a National Treasure. Entry to the Garan area: JPY 500.

Staying Overnight

About 50 temples offer shukubo (temple lodging), and staying overnight is the reason to come rather than a day trip. The standard experience: tatami rooms with futon bedding, vegetarian dinner (shojin ryori) and breakfast, optional morning ceremony at around 6am. The morning ceremony is worth setting an alarm for; the mountain before the day-trippers arrive is a different place.

Shojin ryori is the most precisely constructed vegetarian cuisine in Japan: tofu in multiple preparations, pickled vegetables, rice, miso, sesame, mountain vegetables (sansai), all made without meat, fish, eggs, or pungent vegetables according to Buddhist dietary rules. At the better temples, the food is genuinely excellent.

Cost has increased significantly: JPY 12,000 to 40,000 per person per night depending on temple and room standard, meals included. Most temples accept cash only; bring enough. Ekoin and Kongo Sanmai-in are well-regarded; Rengejo-in has more elaborate room and garden options. Book through the Koyasan Temple Lodging Cooperative at shukubo.net or directly with individual temples.

Practical Notes

The plateau sits at 900 metres; temperatures run 5 to 10 degrees lower than Osaka year-round. In winter, snow is possible and the mountain has a different character that is worth seeing. Bring a warm layer regardless of the season. Rain is frequent. Koyasan is less known to international visitors than Kyoto or Nara and noticeably less crowded; the combination of genuine religious function and accessibility is rare in Japan, and the mountain rewards coming before it becomes a standard stop on the tourist circuit.
