History and Origins of Myōōji Temple
Founding in the Early Heian Period
Myōōji Temple is said to have been founded by Enrui in the second year of the Kōnin era (811). This period corresponded to the era when Dengyō Daishi Saichō established the Tendai school centered on Mount Hiei Enryakuji Temple, opening a new chapter in Japanese Buddhism. The Koga region had long been an area where mountain ascetic practices and mountain worship flourished, and it is thought that Myōōji Temple was also founded as a center of such faith.
The temple’s name is “Seiryō-zan” (Clear Cool Mountain), and as a Tendai temple, it developed while maintaining deep connections with Mount Hiei Enryakuji Temple. Given the nature of Koga, located in an area also known as the ninja village, it served an important role as a place of prayer for local people and as a place of ascetic practice.
Deep Ties with the Tokugawa Shogunate
Recent investigations have revealed that Myōōji Temple houses the memorial tablets of four generations of Tokugawa shoguns: Tokugawa Ieyasu, Hidetada, Iemitsu, and Ietsuna. This is an important discovery showing that Myōōji Temple had deep connections with the Tokugawa family.
During the Edo period, Koga was the headquarters of the Koga clan, the Koga ninja who served the Tokugawa shogunate. The fact that Myōōji Temple served as a temple to offer Buddhist memorial services for the shogunal family speaks to the historical importance of this region. These memorial tablets continue to be carefully preserved and have become valuable cultural assets of the temple.
The Charm of the Five Great Wisdom Kings Statues
Rare Statues of Five Wisdom Kings in a Tendai Temple
The greatest feature of Myōōji Temple is that it possesses a complete set of Five Great Wisdom Kings, with the principal image of Fudō Myōō at the center and four other wisdom kings arranged in the four cardinal directions (east, west, south, north). It is extremely rare for a Tendai temple to have five complete wisdom king statues, and it is known as a precious treasure throughout the country.
The Five Great Wisdom Kings are important divine beings in Esoteric Buddhism and consist of the following five honored ones:
- Center: Fudō Myōō (The Immovable Wisdom King) – said to be an incarnation of Dainichi Nyorai and the most famous wisdom king
- East: Gōzanze Myōō (The Subduing Wisdom King) – the wisdom king who subdues the three poisons (greed, anger, and delusion)
- South: Gundari Myōō (The Whirling Wisdom King) – the wisdom king who removes demonic obstacles
- West: Daiitoku Myōō (The Great Mighty Wisdom King) – the wisdom king who helps one overcome fear of death
- North: Kongō Yasha Myōō (The Adamantine Yaksha Wisdom King) – the wisdom king who crushes earthly desires
The Principal Image Said to be Carved by Dengyō Daishi Saichō
The principal image of Fudō Myōō at Myōōji Temple is said to have been carved by Dengyō Daishi Saichō himself. Saichō was the founder of the Tendai school and the high priest who established Mount Hiei Enryakuji Temple in the early Heian period. Buddhist statues said to have been carved by Saichō are transmitted in various places throughout the country, and the Fudō Myōō of Myōōji Temple is one of them, having gathered the faith of local people.
The four wisdom kings arranged around the central Fudō Myōō serve as guardians of the four cardinal directions, arranged in a way that enhances the central honored one. This arrangement is based on Esoteric Buddhist mandala philosophy, expressing a religious worldview in which Fudō Myōō sits at the center of the universe while the four wisdom kings guard the four directions.
Visitors can pray before these wisdom king statues, seek to drive away earthly desires, and seek peace of mind. The powerful energy of the wisdom kings will give courage and vitality to those who come to visit.
