Oyama-biraki Grand Festival

Event Overview

The Oyama-biraki Grand Festival (Summer Mountain Opening) is a vital ritual on Mt. Ishizuchi, traditionally known as 'Oyama-ichi' or 'Oyama-biraki.' It marks the sacred journey of the deities from the foot of the mountain to the summit. Starting with the departure ceremony at the main shrine on June 30, the deities visit various shrines across Mt. Ishizuchi from July 1 to July 10. During this period, the mountain enters a state of 'dynamic energy,' drawing tens of thousands of pilgrims. The atmosphere is filled with the sounds of bells and conch shells, creating a mystical scene of people dressed in traditional white robes moving through the mountains.

Highlights & Experiences

The most breathtaking sight is the movement of the deities themselves. On the morning of July 1, you can witness the sacred procession moving from Jojusha Shrine toward the summit shrine, enveloping the entire mountain in a divine atmosphere. While Mt. Ishizuchi has historically been a male-only mountain, the period for female hikers begins on July 2. This is a unique time to experience the traditional culture of greeting fellow hikers with terms like 'Onobori-san' (those ascending) and 'Oshitarisan' (those descending). At Jojusha Shrine, you can also witness special events such as the 'Mochi-maki' (mochi throwing) ceremony and evening rituals like the 'Goshinzo Haitai' (receiving the deity's image).

Participation Tips

If you plan to hike, preparation is essential. If climbing from Jojusha, you must register at the worship association desk, obtain a 'Mountain Ticket' (Tozan Kippu), and wear a 'Red Ribbon' on your left shoulder. If climbing from Toga-ya Haireiden, you must use a 'Green or Blue Ribbon' on your left shoulder. These ribbons are crucial for safety and to prevent hikers from taking the wrong route. Engaging in the traditional greetings of 'Onobori-san' and 'Oshitarisan' is a wonderful way to connect with the local culture.
