About Yagoto Sanzan Koshoji
Yagoto Sanzan Koshoji (八事山興正寺) is a Shingon sect temple located at Yagoto Honmachi, Showa Ward, Nagoya City, Aichi Prefecture. As a special head temple of the Koyasan Shingon sect, it is a prestigious temple with the mountain name Yagoto Sanzan and is affectionately known as Yagoto Kannon. The principal image is Dainichi Nyorai (the Great Sun Buddha), and the grounds are divided into two areas: the Western Mountain Fumon-in, which houses the main hall, and the Eastern Mountain Hensho-in, which houses the inner temple.
Status as “Owari Koya”
Yagoto Sanzan Koshoji is also called “Owari Koya.” This name derives from the temple’s role in embodying the spirit of the Koyasan Shingon sect founded by Kobo Daishi Kukai in the Owari region, serving as a place of learning and practice as well as a center of faith for the people. This designation speaks to the temple’s prestige and historical importance.
History of Yagoto Sanzan Koshoji
Circumstances of Founding
The history of Yagoto Sanzan Koshoji dates back to 1686 (Jokyo 3). It is said that Tenzui Ensho, a high priest (天瑞圓照和尚), was drawn to the spiritual energy of the Yagoto area and established a hermitage there. Tenzui Ensho was an eminent monk who received the five-pronged ritual implement of Kobo Daishi, and he decided to open a training center for Shingon esoteric Buddhism in this location.
In 1688 (Jokyo 5), Tokugawa Mitsutomo, the second daimyo of the Owari domain, took refuge with Tenzui Ensho and granted permission for the construction of various halls, making the temple the place of prayer for the Owari Tokugawa family and a place for Shingon esoteric Buddhist practice. Through the patronage of Tokugawa Mitsutomo, Koshoji developed into a temple with deep connections to the Owari Tokugawa family.
Deep Ties with the Owari Tokugawa Family
Since Tokugawa Mitsutomo’s conversion, Yagoto Sanzan Koshoji established its special position as the prayer temple of the Owari Tokugawa family. Successive Owari domain lords and their families came to worship, making it a place to pray for the peace and prosperity of the domain and family. This relationship continued throughout the Edo period and greatly contributed to the temple’s development. Under the patronage of the Owari Tokugawa family, Koshoji made improvements to its buildings and collected temple treasures, establishing its reputation as “Owari Koya.”
From the Edo Period to the Present Day
Throughout the Edo period, Yagoto Sanzan Koshoji became a place where many monks engaged in rigorous practice in Shingon esoteric Buddhist learning. It also became an object of faith for ordinary people, with worshippers never ceasing to come. Despite being affected by the destruction of Buddhism following the Meiji Restoration, the temple continued its activities and remains one of Nagoya’s representative temples to this day, firmly rooted in the community.
Highlights of the Temple Grounds
The grounds of Yagoto Sanzan Koshoji span approximately 150,000 square meters and form a beautiful space where many historical structures and nature are harmoniously combined.
Five-Story Pagoda (Important Cultural Property)
The most symbolic structure on the grounds is the wooden five-story pagoda designated as a National Important Cultural Property. Built in 1808 (Bunka 5), this five-story pagoda stands approximately 29 meters tall and holds high value as a precious wooden five-story pagoda from the Edo period in Aichi Prefecture.
The architectural style of the pagoda is based on the Japanese tradition, characterized by the curves of the roofs at each level and the beauty of its structural brackets. Harmonizing with the surrounding nature throughout the seasons, it creates a painterly landscape especially during cherry blossom season and autumn foliage season. While the five-story pagoda can only be viewed from the outside, its solemn appearance leaves a deep impression on visitors.
Western Mountain Main Hall (Fumon-in)
The Western Mountain Main Hall is the central structure of Koshoji and houses the principal image of Dainichi Nyorai. Daily services are performed in the hall, allowing worshippers to calm their hearts in a tranquil space. The architecture of the main hall is both solemn and warm, embodying the worldview of Shingon esoteric Buddhism.

Inner Temple (Eastern Mountain Hensho-in)
Located on the eastern side of the grounds, the inner temple is positioned as a place of deeper faith and practice. Enveloped in silence, the space is suitable for meditation and prayer, providing spiritual peace to visitors. The approach path to the inner temple is surrounded by trees, making it a healing space that helps one forget the hustle and bustle of the city.
