History and Origins

The ancient chronicles Kojiki and Nihon Shoki tell us that Omononushi-no-Okami appeared from beyond the sea to help Okuninushi-no-Kami build the nation, and wished to enshrine himself on Mount Miwa. During the reign of Emperor Sujin (from 97 BCE), Otataneko was appointed as the chief priest to appease Omononushi's spirit, which is considered the origin of the shrine's current rituals.

Omiwa Shrine, often referred to as "the shrine of shrines" or "Japan's oldest shrine," maintains an ancient form of worship where no sanctuary is built, and Mount Miwa itself is revered as the sacred body from afar. This practice represents the most primordial aspect of Shinto. Under the name Miwa Myojin, the shrine has long been revered as the supreme guardian of sake brewing, agriculture, and medicine.

Frequently Asked Questions (FAQ)

Q1. I want to try ascending Mount Miwa (Tohhai), is it okay for beginners?

A. The mountain is 467m high, and the round trip takes 2 to 3 hours. It's considered an intermediate level for general hiking. Hiking boots, water, and proper physical condition management are essential, and entry is prohibited during rain or stormy weather. Please follow the instructions at the reception and approach it with a mindset of sacred worship.

Q2. I often hear it referred to as "Japan's oldest shrine," is that true?

A. The more accurate expression is "one of Japan's oldest shrines." It preserves the ancient form of worship where there is no main sanctuary and the mountain itself is the sacred body, representing the earliest layer of Shinto before shrine architectural styles were established. Alongside other shrines that also claim to be among Japan's oldest (such as Isonokami Jingu), it conveys the primordial form of Shinto to this day.

Q3. Why are eggs offered to the Mi-no-Kami Sugi?

A. The Kojiki and Nihon Shoki relate that Omononushi-no-Okami appears in the form of a white snake (mi). It's an ancient custom to offer eggs and sake, which are favored by snakes, at the foot of the Mi-no-Kami Sugi.

Q4. What is the origin of the Nade Usagi (Petting Rabbit)?

A. The Petting Rabbit statue in front of the worship hall originates from the "Usagi no Hi Mairi" (Rabbit Day Pilgrimage) held at Omiwa Shrine. It's a very popular statue among visitors, believed to have divine efficacy for recovery from illness if you pet the same part of the statue as your ailment.

Q5. What about the deity of sake?

A. Omononushi-no-Okami is the guardian deity of sake brewing. Throughout the shrine grounds, you'll see sugidama (cedar balls, signifying freshly brewed sake) donated by sake breweries from all over Japan. Every November, sake breweries nationwide hold their "Sake Brewing Safety Prayer Festival" at Omiwa Shrine.

Editor's Note

For me, Sun-chan, Omiwa Shrine is "the shrine where you know the deity's address." There's no main sanctuary, just the act of gazing up at Mount Miwa. There are no grand architectural decorations or flashy symbols. Yet, the sheer fact that "the deity resides in that mountain" is solemn enough, making it a rare place where you can experience "the origin of prayer" from before modern shrine architecture began. On days I've completed the sacred ascent of Mount Miwa, I find my sleep that night is deeper—that's the kind of special shrine it is.
