Kashimori Shrine (橿森神社)

Kashimori Shrine sits on a forested hill in central Gifu City, and according to its founding legend, the site was chosen by a celestial horse. When the god Tenma descended from the heavens, his mount — a winged horse of mythology — stamped the ground here with such force that a sacred oak tree (kashi) sprouted instantly from the earth. The tree became the shrine’s name and its soul. For over a millennium, this small sanctuary has watched Gifu transform from castle town to modern city, yet the hill remains unchanged — a green island of ancient oak and stone in an ocean of concrete.

Kashimori Shrine was founded in the early Heian period, traditionally dated to 806 CE, though the site likely held sacred significance long before formal construction. The shrine served as a protective sanctuary for the people of what was then called Inokuchi, a settlement that would eventually become modern Gifu City. During the Sengoku period, the shrine gained the patronage of Saitō Dōsan, the warlord who built Gifu Castle on the nearby mountain, and later Oda Nobunaga, who renamed the city Gifu in 1567. The current main hall was reconstructed in the early Edo period following damage during the civil wars, and the shrine has been continuously maintained by local devotees ever since.

Ichikishimahime no Mikoto is the primary deity of Kashimori Shrine, one of the three Munakata goddesses born from Susanoo’s sword in the primordial creation myths. She is the goddess of water, maritime safety, and beauty, and is often syncretized with Benzaiten, the Buddhist deity of music and eloquence. The shrine also enshrines Amenohohi no Mikoto, a son of Amaterasu sent to pacify the earthly realm in the Kojiki, and Sugawara no Michizane, the deified scholar-statesman of the Heian court. This unusual combination reflects the shrine’s layered history — water worship, imperial authority, and scholarly devotion compressed into a single hilltop.

The founding story of Kashimori centers on the descent of Tenma, a divine messenger who arrived at this hill riding a white celestial horse with wings of cloud. When the horse’s hooves struck the earth, a magnificent oak tree burst from the ground in full maturity, its roots spreading through the hill like veins. The tree was taken as proof of divine selection, and a shrine was built around its base. The oak became known as the goshintai — the physical body of the god — and was revered as such for centuries. Though the original tree eventually died, successive oaks have been planted and consecrated in its place, maintaining an unbroken lineage of sacred trees. Local tradition also holds that Ichikishimahime appeared in the dreams of early shrine priests, requesting that the site be protected as a place where water and sky meet — the hill’s natural springs were seen as her earthly manifestation.

The shrine complex is modest but beautifully preserved, centered on a simple nagare-zukuri style main hall with a gracefully curved roof. The approach begins at the base of the hill with a stone torii gate flanked by centuries-old stone lanterns, then ascends through a forest of oak and camphor trees via worn stone steps. Near the summit stands the sacred oak — a massive tree estimated to be over 300 years old — enclosed by a shimenawa rope and surrounded by smaller shrine buildings. A small spring feeds a purification basin carved from a single stone, its water still used by visitors for ritual cleansing. The grounds also contain several subsidiary shrines dedicated to Inari, Kompira, and other local protective deities, reflecting the syncretism typical of neighborhood shrines in castle towns.

• Tenma Festival (May 5) — The main annual festival celebrating the celestial horse legend, featuring processions, ritual dances, and offerings of sake beneath the sacred oak tree.
• Autumn Grand Festival (October 9-10) — Traditional mikoshi portable shrine parades through the Kashimori district, accompanied by taiko drumming and lion dances performed by local preservation societies.
• Hatsumode (January 1-3) — New Year’s first prayers draw local residents who climb the hill to receive blessings for the coming year, particularly students seeking academic success through Michizane’s intercession.
• Monthly Water Ritual (1st of each month) — Priests perform a dawn purification ceremony at the sacred spring, maintaining a practice that dates to the shrine’s founding.

Early morning in late April or early May, when the forest canopy turns brilliant green and the oak trees are in full leaf. The hill catches the first sunlight over Gifu City, and on clear days, you can see Mount Kinka and Gifu Castle rising to the west. Autumn — particularly early November — brings spectacular color to the maple trees planted along the approach, creating a corridor of crimson and gold. The shrine is quietest on weekday mornings, when you’re likely to have the hilltop to yourself except for the elderly residents who come to pray at the subsidiary shrines.
