About this place
Oyunohara is the former sacred precinct of Kumano Hongu Taisha located in Hongu-cho, Tanabe City, Wakayama, on a sandbank at the confluence of Kumano, Otonashi, and Iwata Rivers. For about 1,100 years, until 1889, the shrine occupied this area known as Oyu no Hara. After the great flood of the Kumano River in Meiji 22 washed away nine of 12 shrine buildings, the remaining deities were moved in 1891 to the current higher site. Today two small stone shrines mark the original lot, and in 2000 a giant torii gate 33.9 meters high and 42 meters wide was erected to commemorate the sacred ground, considered Japan's largest torii built of weathering steel-like reinforced concrete with timber cladding appearance. The entire Oyunohara is part of the UNESCO World Heritage Sacred Sites and Pilgrimage Routes in the Kii Mountain Range inscribed 2004 as terminus of the Kumano Kodo Nakahechi route. The 110,000 square meter precinct is covered by sacred sand, surrounded by cedar grove and Yatagarasu crow banners, creating solemn atmosphere. Annual rites include Yuto Shinji hot water ritual April 13 parading mikoshi. Access: 90-120 minutes by Ryujin Bus and Kumano Gobo Nankai Bus from JR Kii-Tanabe or Shingu Station to Hongu Taisha-mae stop, then 5 minutes walk. Oyunohara stands 10 minutes walk from present Hongu Taisha, allowing pilgrims to feel continuity of Kumano worship linking river, mountain, and ocean.
