Toga Shrine — 砥鹿神社

Toga Shrine exists in two places simultaneously. The main shrine sits in the flatlands of Toyokawa city, but its inner shrine — the okusha — occupies the summit of Mount Hongū, 789 meters above. This geographical split embodies a theological principle: the mountain is the original seat of the deity, while the valley shrine serves as the interface between divine power and human need. For over 1,300 years, pilgrims have climbed the forested slopes to reach the mountain sanctuary, while daily worshippers attend the accessible valley shrine — two expressions of the same sacred presence.

Toga Shrine was formally established in 701 CE during the Taihō era, though worship at Mount Hongū predates this by centuries. The mountain itself was considered a sacred dwelling long before any structure was built. The valley shrine — now the main worship hall — was constructed later to accommodate increasing numbers of pilgrims who could not make the mountain ascent. By the Heian period, Toga had become the ichinomiya of Mikawa Province, the highest-ranking shrine in the region. This status reflected both its antiquity and its control over the sacred mountain. The shrine survived the warfare of the Sengoku period under the protection of the Tokugawa clan, whose ancestral territory included this area. In 1876, the shrine was designated a national shrine (kokuhei taisha), cementing its importance in the modern Shinto system.

Ōnamuchi no Mikoto is the principal deity, better known by the name Ōkuninushi — the Great Master of the Land. This is the deity who built the nation before ceding it to the heavenly gods, and who governs the unseen world (yūkai). At Toga, Ōnamuchi is specifically worshipped as the deity of the mountain and the protector of agricultural fertility. His presence in both the summit shrine and the valley shrine represents the complete cycle of blessing: rain and growth descending from the mountain, gratitude and offerings ascending from the fields. Two additional deities are enshrined alongside him: Sukunahikona no Mikoto, his companion in nation-building, and Take-Minakata no Mikoto, a deity of military valor.

The founding legend tells of a Shinto priest named Yukinomiya who, in the seventh century, received a divine revelation while meditating on Mount Hongū. The deity Ōnamuchi appeared to him in a dream and declared that the mountain had been his dwelling since the age of the gods, and that a shrine should be established to formalize worship. Yukinomiya climbed the mountain and built the first structure at its summit. The name “Toga” itself derives from the mountain’s original name, Mount Toga, written with characters meaning “whetstone deer” — though the exact origin of this name is lost. Local tradition holds that the mountain once produced whetstones of exceptional quality, and that deer were sacred messengers of the mountain deity. Another legend describes how the deity once saved the region from drought by releasing water from the mountain springs, establishing Toga as a shrine for rain prayers.

The valley shrine complex features a grand haiden (worship hall) built in the ornate gongen-zukuri style, with connected structures under a single roof. The vermilion-lacquered buildings are surrounded by ancient cedar and camphor trees, some over 400 years old. A 300-meter approach from the main torii passes through a forested precinct that insulates the shrine from the surrounding city. The summit shrine (okusha) on Mount Hongū is reached by a hiking trail that takes approximately 90 minutes from the trailhead. This small shrine, reconstructed in stone and wood, sits on a rocky outcrop with views across the Toyokawa plain to the Pacific Ocean. Stone markers along the trail indicate stations for prayer and rest, remnants of the medieval pilgrimage route. Many pilgrims leave small offerings of coins and paper prayers at the summit.

• Rei-Taisai (Grand Annual Festival, May 3-5) — The shrine’s most important festival, featuring processions, ritual dances, and offerings carried from the valley shrine toward the mountain.
• Hatsumode (New Year Worship, January 1-3) — One of the most popular first-shrine visits in Aichi Prefecture, drawing tens of thousands of worshippers.
• Mountain Opening Ceremony (April) — A ritual that marks the beginning of the climbing season and purifies the mountain trails.
• Autumn Harvest Festival (October) — Thanksgiving offerings for the year’s agricultural yield, traditionally including rice and sake from local farms.

Late October through early November, when autumn leaves color the mountain trails and the weather is ideal for the summit climb. The ascent to the okusha becomes a moving meditation through red and gold foliage. For those visiting only the valley shrine, early morning on weekdays offers the quietest atmosphere. Avoid the first three days of January unless you wish to experience the intense energy of hatsumode crowds.
