Amanosan Kongoji Temple

A Mountain-Valley Temple Known as the Women's Koya

Amanosan Kongoji Temple (天野山金剛寺, Amanosan Kongō-ji) is a head temple of the Omuro branch of Shingon Buddhism in Amanocho, Kawachinagano City, Osaka Prefecture, whose precinct was designated a national Historic Site in 1934. Tradition holds that the monk Gyoki founded it in the Tenpyo era (729 to 749).

According to the temple's own history, the site later came to be regarded as a place where Kobo Daishi (Kukai) trained, but it fell into ruin over roughly four centuries. Late in the Heian period the monk Akan arrived from Mount Koya. With the support of the retired Emperor Go-Shirakawa and his sister, Hachijo-in, he built the Mieido to enshrine a portrait of Kobo Daishi, began memorial rites in his honour, and restored the main hall, pagoda, gate, and refectory. Amanosan Kongoji Temple became Hachijo-in's place of prayer and remained a prayer temple for successive imperial ladies. Because so many women placed their faith in it, it is known as Nyonin Koya, the Koya for women, in contrast to Mount Koya, which long barred women.

During the fourteenth-century conflict between rival courts, the temple sided with the Southern Court. Emperor Go-Murakami used the sub-temple Mani-in and the refectory as his temporary palace for five years from 1354, and for more than three of those years the retired Northern Court emperors Kogon, Komyo, and Suko, together with Prince Naohito, were held at the sub-temple Kanzoin.

Once the conflict ended, rice, timber, and charcoal from temple lands underpinned its economy, and the number of sub-temples grew beyond 90. Amano sake, brewed within the precinct, won a wide reputation. Toyotomi Hideyori repaired the halls in 1605 and 1606, and in 1700 Okabe Nagayasu, lord of Kishiwada, oversaw further repairs on the orders of the shogunate.

In the Meiji era, anti-Buddhist sentiment swept away most sub-temples, and some of the survivors were merged into Kongoji in 1888 and 1911. Between 2009 and 2017 the main hall, the pagoda, and the bell tower underwent major restoration.

How the Precinct Is Laid Out, and a Route Through It

Amanosan Kongoji Temple fills the long, narrow Amano valley, through which the Nishiyoke River, locally called the Amano River, runs north to south. The central compound lies west of the river, where the main hall (Kondo), the Tahoto pagoda, the bell tower, the Mieido, and the refectory stand on stepped terraces. The two-storey Romon gate marks the entrance. On the highest terrace are the Gobutsudo and the Yakushido, and above them the Gumonjido and the Kaisando.

North of the central compound is Mani-in, the sub-temple that served as the Southern Court's palace. The Honbo, the administrative quarters, occupies the former sites of Chuin and Kanzoin; around its garden stand the Grand Entrance, the guest hall, the Jibutsudo chapel, the tea room, the Okuden, a connecting corridor, and a front gate, all dating from the mid-Edo to the Taisho periods.

Sub-temples once lined the east bank of the river. Today an earthen wall along the water and the gates of former Rishu-in and Shinpuku-in recall them, and their old plots hold the early Showa Great Lecture Hall and its refectory as well as the mid-Meiji Muryojuin and Komorido. The guardian shrine sits on the hill to the east, reached by the Chinju Bridge near the precinct entrance.

One way to see it all: get off the bus at Amanosan, pass through the Romon into the central compound, and look at the main hall and pagoda. Then visit the Honbo garden and buildings. Finish with a walk along the Amano River, viewing the east-bank wall and sub-temple gates from outside; this order traces how Amanosan Kongoji Temple grew from medieval halls to modern buildings.

Important Cultural Properties and Registered Buildings

Amanosan Kongoji Temple was recognised in stages. The precinct was designated a national Historic Site on March 13, 1934, and in 2011 the designation was extended to the southern half of the grounds, where the sub-temples stood, and to the surrounding hills.

Among the buildings, the main hall, the pagoda, the bell tower, the Romon gate, the refectory, and the Mieido are each Important Cultural Properties. On December 27, 2019, twenty-two further structures, including the Gobutsudo, the Yakushido, the Gumonjido, the Kaisando, the storehouses, the shrine buildings, the gates of former Rishu-in and Shinpuku-in, the South Gate, and the outer gate, were designated together as an Important Cultural Property under the name Kongoji. Kawachinagano City explains that the precinct is one of few places where buildings erected before the mid-Edo period survive as a group and preserve the historic scenery.

On June 28, 2017, twelve structures dating from the mid-Edo period to the early Showa period were listed as Registered Tangible Cultural Properties: the Honbo guest hall, Jibutsudo, Grand Entrance, Okuden, connecting corridor, tea room, and front gate, plus the east-bank earthen wall, the Chinju Bridge, the Great Lecture Hall, its refectory, and the Muryojuin and Komorido. Each has its own page describing its history and features.

The temple also notes that it is a key component of two Japan Heritage stories, one recognised in fiscal 2019 and one in fiscal 2020, the latter centred on the Women's Koya tradition.
