Detailed History

The Kii Mountain Range, with peaks rising above 1,000 meters, was venerated as a sacred landscape long before Buddhism arrived in Japan, and its forested slopes lay close to the ancient capitals of the Nara basin. Mountain ascetics began retreating to the Kii peaks in the late 7th century. In 816 CE, the monk Kukai, recently returned from Tang China, received Mount Koya from Emperor Saga and founded atop the plateau the head temple of Shingon Esoteric Buddhism, Kongobuji. From the 10th and 11th centuries the ascetic Shugendo tradition, tracing its founder to En no Gyoja, flourished on Yoshino and Omine to the north and on the Kumano Sanzan to the south, weaving Shinto kami worship together with Esoteric Buddhist practice into a uniquely Japanese syncretism. The Kumano Sanzan — Hongu, Hayatama, and Nachi — became the most powerful pilgrimage destination in late Heian and Kamakura Japan, with Retired Emperor Shirakawa undertaking nine recorded imperial pilgrimages there from 1090 onward and Retired Emperor Go-Shirakawa an astonishing 34 in the latter 12th century. In the Muromachi period the procession of commoners on the Kumano Kodo became so dense that chroniclers coined the phrase 'ari no Kumano-mode,' the ants' march to Kumano, with pilgrims of every class, gender, and creed accepted under the figure of Kumano Gongen. In 1581 Oda Nobunaga began an assault on Koyasan, suspended when he died at the Honnoji incident in 1582 and sparing the monastery. The Meiji 1868 Shinto-Buddhist separation edict and the 1872 Shugendo prohibition broke the religious unity of the Kii peaks, but the temples and shrines themselves survived. National Treasure and Important Cultural Property designations followed under the postwar Cultural Properties Protection Law. On July 7, 2004, the 28th World Heritage Committee inscribed the property as Japan's twelfth World Heritage and the first ever inscription of a road and of a cultural landscape from Japan. The protected area totals 11,865 hectares, the largest of any Japanese cultural property on the list. A minor revision approved in Paris on October 26, 2016 added 40.1 kilometers of pilgrim path, including stretches of Nakahechi, Ohechi, and the Koyasan Choishi-michi.

Cultural Significance

The inscribed property bundles three sanctuaries — Koyasan, Yoshino-Omine, and the Kumano Sanzan — with six historic pilgrim trails: Nakahechi, Ohechi, Kohechi, Iseji, Omine Okugakemichi, and the Koyasan Choishi-michi. In all, 242 components of shrines, temples, stone markers, and trail segments were nominated together. This is the first time a road has ever been inscribed on the World Heritage List from Japan, and one of only two pilgrim-road inscriptions worldwide — the other being the Camino de Santiago in Spain — with which Wakayama Prefecture and Galicia formalized a sister-route agreement in 1998. The property meets World Heritage criteria (ii), (iii), (iv), and (vi), with the citation singling out the 'unique fusion of Shinto and Buddhism' and a 'tradition of sacred mountains documented over more than 1,000 years.' Within the national system, key buildings such as the Fudo-do of Kongobuji and the honden of Kumano Hongu Taisha are National Treasures or Important Cultural Properties; large parts of Yoshino-Omine and the Kumano mountains carry National Place of Scenic Beauty and Historic Site designations. The Kii landscape has appeared in NHK historical dramas about the Heian court, in films by Takashi Miike and Hirokazu Kore-eda, and in many travel documentaries that have driven a steady rise of international visitors since the 2004 inscription.

Architectural Details

The religious architecture of the Kii Mountain Range spans an unusually broad spectrum, from the oldest Shinto styles — Shinmei-zukuri, Kasuga-zukuri, Hachiman-zukuri — to the great Esoteric Buddhist pagodas. The Konpon Daito at Koyasan, begun by Kukai in 819 as Japan's first tahoto-style esoteric pagoda, stands today as a 1937 reconstruction roughly 49 meters high, embodying a three-dimensional mandala in vermilion-painted wood and copper-tiled roofs. The honden of Kumano Hongu Taisha employs the distinctive Kumano-zukuri style: a hip-and-gable roof with shingled bark, a forward-projecting chidori-hafu gable, and broad sweeping eaves rare in mainland Japanese shrine architecture. The three-storied pagoda of Seigantoji, reconstructed in 1992, frames Nachi Falls in what may be the single most photographed temple-and-waterfall composition in Japan. Along the pilgrim trails themselves, the stone pavement, lanterns, oji shrine sites, and the choishi five-element stone markers placed every cho along the Koyasan Choishi-michi — 216 in total — constitute religious infrastructure dating back a millennium. Simultaneous evaluation of monumental buildings and the roads that link them is rare in World Heritage practice and was a deliberate feature of the Kii inscription.
