History of Kozenji Temple
Founding and the Heian Period
Kozenji Temple is said to have been founded in 860 (Jogan 2) by the high priest Honsei (本聖), a distinguished monk of the Tendai sect. After training at Enryakuji Temple on Mount Hiei, Honsei built a temple hall at this location and enshrined Fudo Myoo as the principal deity.
From its inception, the temple received imperial patronage and had already developed into a substantial temple by the Jogan period. Backed by the sacred peak of Mount Komagatake in the Central Alps, it flourished as a center of Shugendo practice, attracting many training monks as a place of practice.
Status as One of the Five Tendai Mountains of Shinano
From the Heian through Kamakura periods, Kozenji was counted as one of the Five Tendai Mountains of Shinano (Kenkoji of Mount Togakushi, Zenkoji, Sarashina Hachiman Shrine Temple, Tsugane Temple, and Kozenji), establishing itself as an important hub of the Tendai sect in Shinano Province.
During this era, the temple possessed extensive lands and vast numbers of subsidiary temples, flourishing as a great temple. Particularly during the Kamakura period, the current scenic garden was constructed, creating a landscape where temple architecture and nature harmonized.
Sengoku Period and the Patronage of Warlords
As the Sengoku period began, Kozenji received the patronage of the Takeda clan, who ruled Shinano Province. Takeda Shingen valued Kozenji and devoted effort to securing its temple lands and repairing its buildings. After the Takeda clan’s fall, patronage shifted to Toyotomi Hideyoshi and then Tokugawa Ieyasu, but in all eras the temple’s status and lands were maintained.
Development in the Edo Period
Upon entering the Edo period, the Tokugawa shogunate granted the temple 300 koku in sealed lands, establishing a stable economic foundation. During this era, many temple buildings were maintained and rebuilt, forming the foundation of the current temple complex. Additionally, the number of pilgrims increased, and the temple developed as a center of common people’s faith.
Modern Era and Beyond
Though affected by the Meiji period’s suppression of Buddhism, Kozenji persisted as the spiritual center of the region. In 1967 (Showa 42), its garden was designated a National Scenic Spot, and its cultural value was officially recognized. Today it continues to serve as an important prayer temple in southern Shinano as a Special Honzan of the Tendai sect.
The Legend of the Sacred Dog Hayataro
Inseparable from any discussion of Kozenji Temple is the legend of the sacred dog Hayataro (早太郎). This tale, transmitted since medieval times, continues to captivate many.
The Story of the Hayataro Legend
At Mitsuke Tenno Shrine (Yanabime Shrine) in Enshu (present-day Shizuoka Prefecture), there was an annual custom of offering a young maiden as a human sacrifice to the deity. A traveling monk discovers that the cause of this sad custom is the actions of a demon who fears the mountain dog “Hayataro” from Kozenji Temple in Shinano Province.
The monk visits Kozenji, borrows Hayataro, and takes him to Mitsuke Tenno Shrine. On the night of the human sacrifice ritual, Hayataro engages in fierce battle with the demon and vanquishes it. However, Hayataro himself sustains grievous wounds and passes away shortly after returning to Kozenji.
Hayataro’s Tomb and Faith
Within Kozenji Temple’s grounds is Hayataro’s tomb, which remains visited by many pilgrims today. A wooden statue of Hayataro is enshrined in the main hall, honoring his loyalty and courage. In the temple grounds, a stone statue of Hayataro has also been erected and is popular as a photography spot.
This legend is praised not only for the dog’s loyalty and bravery but also as a story demonstrating that Kozenji is a temple of miraculous efficacy, and is widely cherished. Even today, many pilgrims visit to pray for the health of their pets, and the temple is known as a place for pet memorialization.
