"Where mountain deity and monkey messengers guard against misfortune"
Hiyoshi Taisha
Otsu, Shiga Prefecture, Japan
At the foot of sacred Mount Hiei, Hiyoshi Taisha has served as spiritual guardian for over two thousand years. The shrine protects against evil from the northeast—the demon gate direction in East Asian cosmology—and leads a network of 3,800 affiliated shrines across Japan. Monkeys, considered divine messengers since ancient times, appear throughout the complex as protectors. In April, the Sanno Festival reenacts divine marriage and birth with mikoshi processions that have continued for nearly a millennium.

Hiyoshi Taisha enshrines the mountain deity Oyamakui, formally recognized since 90 BCE, and serves as head of nearly 4,000 affiliated shrines across Japan.
Origin Story
According to the Kojiki, the kami Oyamakui has resided on Mount Hiei from ancient times. In the seventh year of Emperor Sujin's reign—traditionally dated to 90 BCE—this deity was formally enshrined at the mountain's foot, establishing what would become the Higashi Hongu (Eastern Main Hall). Centuries later, when Emperor Tenji moved the capital to Omi Province in 668 CE, he relocated the kami from Omiwa Shrine in Yamato to create the Nishi Hongu (Western Main Hall). The shrine's protective function expanded dramatically in 788 CE when the monk Saicho founded Enryaku-ji on the summit above. For the next thousand years, the shrine and temple worked together—the mountain deity protecting the Buddhist establishment, the monks honoring the kami—until the Meiji restoration forcibly separated them.
