Kumano Shrine Main Hall

Kumano Shrine Main Halls: A Sacred Outpost of Kii Kumano in Setouchi

Tucked into the gentle hills of Hayashi in Kurashiki City, Okayama Prefecture, the Main Halls of Kumano Shrine (Kumano-jinja Honden) form one of the most distinctive shrine groupings in western Japan. Six independent halls stand in a single line facing south, mirroring the layout of the great Kumano Hongū-taisha in Kii Province. The central Second Hall, rebuilt in 1492, is designated a National Important Cultural Property and ranks among the finest mid-Muromachi shrine buildings in the Chūgoku region. Although small in scale, it is rich in painted ornament and refined carpentry — a quiet treasure that rewards travelers who venture beyond Japan's better-known pilgrimage routes.

A Sanctuary Founded in the Year 701

The shrine's origins reach back to the dawn of the eighth century. According to its founding tradition, in the third month of 701 (Taihō 1), five disciples of the mountain ascetic En no Gyōja carried the divine spirit of Kumano Hongū from Kii Province (modern Wakayama) and enshrined it on this site in the Kojima district. The complex was modeled on the original Kumano Hongū-taisha and came to be known as the Kumano Twelve Shrines (Kumano Jūnisha Gongen).

By the mid-eighth century the imperial court had granted Kojima as shrine lands, and the area developed into one of the most important Kumano outposts outside Kii. Together with the New Kumano shrines at Kimi and Yamamura, it formed the so-called Shin-Kumano Sanzan — three sacred mountains modeled on those of Kii. From the late Heian period onward, retired emperors and aristocrats made pilgrimages here, and the precinct became a major center of Shugendō mountain asceticism.

Fire, Exile, and Reconstruction

In 1221, after the failed Jōkyū Disturbance, the fourth prince of retired Emperor Go-Toba, Prince Yorihito, was exiled to this district and devoted himself to restoring the shrine and its associated temples. Under his patronage the complex flourished into the Nanboku-chō era.

During the Ōnin War, however, the shrine was caught in the conflict and almost entirely destroyed by fire in 1469. Reconstruction began in 1492 (Meiō 1), and the building completed at that time survives today as the Second Hall — the oldest of the six and the only one designated as a national treasure-class property. The remaining five halls were rebuilt much later, in 1647 (Shōhō 4), under the patronage of Ikeda Mitsumasa, the daimyō of the Okayama domain. With the Meiji-era separation of Shintō and Buddhism, the complex was reorganized as a purely Shintō shrine and given its present name, Kumano Shrine.

Why the Second Hall Is Designated a National Treasure

The Second Hall was designated an Important Cultural Property of Japan on April 30, 1921 — one of the earliest such designations in Okayama Prefecture. The other five halls received prefectural designation on April 19, 1968.

The Second Hall's value lies in three areas. First, its date: 1492 places it firmly in the middle Muromachi period, an era from which relatively few painted shrine buildings survive in the Chūgoku region. Second, its architectural type: a one-bay-by-two-bay sumi-ki-iri kasuga-zukuri (a Kasuga-style hall with diagonal hip rafters), fronted by a one-bay kōhai (covered approach), with a hinoki cypress-bark roof crowned by chigi finials and katsuogi billets. Third, its decoration: pillars, rafters, virtual tie-beams, and gable boards are coated in vermillion lacquer; the cut ends are colored with yellow ochre; and the plank walls and inner boards are finished in white gofun shell-lime. The result is a small but exceptionally finely composed building whose curved bargeboards, double-tier rafters, and front fukiyose lattice combine into a quiet harmony.

The Six Halls in a Row: A Living Echo of Kumano

What makes a visit truly memorable is not the Second Hall in isolation but the way all six halls stand together. Reading from left to right as one faces the precinct, the order is Third, First, Second, Fourth, Fifth, and Sixth. This unusual arrangement deliberately mirrors that of Kumano Hongū-taisha in Wakayama, making this complex one of the few places in Japan where the layout of the original Kumano sanctuary can still be appreciated in something close to its medieval form.

The five halls rebuilt in 1647 each follow a different style: the First Hall is in kasuga-zukuri (closely echoing the Second Hall), the Third Hall in irimoya-zukuri, and the Fourth, Fifth, and Sixth Halls in nagare-zukuri. All are roofed in hinoki cypress bark, but unlike the Second Hall they are left as plain unfinished wood (shiraki-zukuri), giving the complex a striking contrast between vermillion and natural cedar tones. The Sixth Hall is particularly interesting: it is dedicated to the local jinushi-gami who guards the ground on which Kumano Gongen resides — a feature that mirrors a similar arrangement at the original Hongū in Kii.

Highlights for the Visitor

For travelers, the main pleasures of a visit are visual and atmospheric. Stand directly in front of the precinct and take in the rhythm of the six gabled roofs in line — a view rarely encountered elsewhere. Step slightly to the side to compare the painted Second Hall with the bare-wood First Hall beside it; the contrast in surface treatment makes both buildings more legible.

Around the precinct, look out for the related properties of the Goryū Sonryū-in, the Shugendō headquarters historically tied to the shrine. Its three-storied pagoda is an Important Cultural Property in its own right, and the surrounding pine groves give a sense of the wider sacred landscape. Annual festivals, including the autumn grand festival with mikoshi processions and the summer chinowa-kuguri purification ritual, provide a window into the living traditions of the community.

Visiting and Surrounding Attractions

The shrine sits in the Gōnai district of southern Kurashiki, easily reached as a half-day excursion from central Kurashiki or Okayama. The grounds are open year-round, and there is no admission fee for the precinct. Visitors are asked to remain outside the inner enclosure, but the six halls are clearly visible from the worship area.

After visiting, consider extending the day with the related Yuga Shrine and Rendai-ji to the southwest — together with this Kumano Shrine they form the Shin-Kumano Sanzan circuit. The historic Bikan district of Kurashiki, with its white-walled merchant houses and the Ohara Museum of Art, makes an excellent contrast for the second half of the day, and the seaside town of Shimotsui offers fine views of the Great Seto Bridge.
