Hie Shrine (日枝神社) enshrines Oyamakui-no-kami, the mountain deity of Mt. Hiei, whose principal head shrine is Hiyoshi Taisha in Otsu, Shiga Prefecture. When Tokugawa Ieyasu designated the shrine as the guardian of Edo Castle in the early 17th century, the Nagatacho branch in Tokyo became one of Japan’s most prestigious urban shrines, still frequented by politicians and business leaders today.

The Enshrined Deities — Who Is Oyamakui?

Oyamakui in Japanese Mythology

Oyamakui-no-kami appears in the Kojiki as the lord of mountains — his name literally means “one who drives stakes into the great mountain.” He governs agriculture, sake brewing, and matrimonial bonds. Mt. Hiei itself is considered the sacred body of this deity.

The Sanno Faith and Tendai Buddhism

When Saicho founded Enryakuji Temple on Mt. Hiei in 788, Oyamakui was adopted as the guardian deity (Sanno Gongen) of the Tendai sect. This merging of Shinto and Buddhism — called shinbutsu shugo — made the “Sanno faith” one of the most powerful religious currents in medieval Japan.

Imperial and Aristocratic Patronage

Mt. Hiei stands to the northeast of Kyoto — the direction of evil in traditional cosmology — making it the capital’s spiritual shield. Successive emperors made pilgrimages to Hiyoshi Taisha, and the Fujiwara clan maintained close ties to the shrine. This imperial patronage propelled Sanno worship into every province.

Tokugawa Edo and the Mountain King

Ieyasu moved the Sanno shrine to Nagatacho to guard Edo Castle’s vulnerable direction. The Hie Shrine in Nagatacho then became the tutelary shrine of the Tokugawa shogunate. The Sanno Festival — held every June — was one of Edo’s three great festivals, watched by the sitting shogun himself.
