Owari Ōkunitama Shrine — 尾張大国霊神社

Owari Ōkunitama Shrine sits on what was once the political centre of Owari Province, functioning as the sōja — the provincial consolidation shrine where governors performed state rituals to all the province’s deities at once. This administrative role, established in the Heian period, made it possible for officials to venerate hundreds of local kami without traveling to individual shrines. The institution has outlasted the province itself: Owari Province dissolved in 1871, but the shrine continues to hold its annual Hadaka Matsuri, in which thousands of nearly-naked men struggle in winter darkness for wooden talismans believed to absorb misfortune. It is one of the three great hadaka festivals of Japan, and it transforms the former bureaucratic centre into a scene of controlled chaos every January.

The shrine’s founding is attributed to the reign of Emperor Seinei (late 5th century), though its role as provincial sōja was formalized during the Heian period (794–1185) as part of the imperial administration’s kokushi system. Provincial governors would begin their tenure by worshipping here, receiving the spiritual authority of all local deities through a single ritual act. The shrine served this function throughout the medieval period, even as political power shifted away from the old provincial capitals. The current main hall dates to 1661, rebuilt after fire destroyed the Muromachi-period structure. Unlike many shrines that declined when their administrative role ended, Owari Ōkunitama adapted by amplifying its local festival traditions, particularly the Hadaka Matsuri, which grew from a purification rite into a mass participation event that now draws 10,000 participants annually.

Ōkuninushi no Mikoto is the primary deity, known as the “Great Land Master” who governed the earthly realm before ceding it to the imperial ancestral kami. He is associated with nation-building, agriculture, medicine, and matchmaking — a deity of foundational order rather than transcendent power. As a sōja, the shrine also venerates the collective spirits of all shrines that once existed within Owari Province, creating a layered spiritual jurisdiction. This multiplicity means visitors are technically praying to dozens of kami simultaneously, a theological efficiency that mirrors the shrine’s original administrative purpose. Ōkuninushi’s messenger is the rabbit, referencing the Inaba no Shiro Usagi legend from the Kojiki.

The shrine’s most distinctive legend concerns not its founding but its survival. During the Sengoku period, when Oda Nobunaga was consolidating power in Owari, he ordered the shrine’s sacred forest cleared for military use. The head priest confronted him directly, warning that the land belonged to Ōkuninushi and that disturbing it would bring calamity. Nobunaga, famously irreligious, initially dismissed this — but that night, according to shrine records, he dreamed of a massive figure standing in flames, declaring “This land is not yours to take.” Whether through genuine fear or political calculation, Nobunaga reversed the order. The forest remains standing, a 16th-century negotiation between earthly and divine authority preserved in living trees.

The main hall (honden) follows the nagare-zukuri style with a distinctive extended roof flowing forward over the front steps, built in 1661 with zelkova wood that has darkened to near-black. The worship hall (haiden) features unusually wide-spaced pillars to accommodate the massive crowds during Hadaka Matsuri. The shrine grounds contain a sacred pond called Kagami-ike (Mirror Pond), historically used for purification before the naked festival participants enter the grounds. An ancient camphor tree near the main gate, estimated at over 800 years old, is wrapped in shimenawa rope and venerated as a dwelling place of kami. The shinboku (sacred tree) survived both the original temple fire and modern development, its trunk scarred but living.

• Konomiya Hadaka Matsuri (January 13) — One of Japan’s three great naked festivals, where thousands of men in fundoshi loincloths pack the shrine grounds in midwinter, attempting to touch the shin-otoko (sacred man) to transfer their misfortunes to him. The event runs from afternoon into night, culminating when the sacred man is passed overhead through the crowd to the main hall.
• Reitaisai (October 2–3) — The annual grand festival featuring mounted archery demonstrations and traditional music performances, celebrating the shrine’s role as spiritual centre of the old province.
• Tsukinami-sai (Monthly on the 1st) — Monthly thanksgiving rituals maintaining the shrine’s ancient function as representative of all provincial deities.

January 13 for the Hadaka Matsuri, if you can tolerate the crowds — attendance exceeds 100,000 spectators. The actual pushing begins around 3 PM and peaks after dark, creating a surreal contrast of sacred violence under floodlights. For quieter contemplation, visit on weekday mornings in autumn when the camphor tree’s leaves turn and the grounds are nearly empty. The shrine’s administrative past makes it less ornate than imperial shrines, but this austerity is itself worth observing — a landscape shaped by bureaucratic rather than aesthetic concerns. October brings the mounted archery without the crushing density of the winter festival.
