Izumo Iwabi Shrine is an ancient and prestigious shrine located in Moroyama Town, Iruma District, Saitama Prefecture. Situated at the foot of Mt. Garyu (Garyusan), it has long served as a guardian for the local community. The name 'Iwabi' is deeply connected to the concept of 'celebration' (iwai), and the shrine remains a beloved site for many. Visitors can experience a profound sense of Japanese tradition through its historic main hall and the seasonal rituals that preserve the area's cultural landscape.
The history of this shrine is exceptionally ancient. Legend traces its origins back to the era of Emperor Keiko, when the deity Okuninushi-no-Mikoto was first enshrined. The shrine's high status was recorded as early as the year 772 (the 3rd year of the Hoki era in the Nara period) as a Kanpei-sha (a shrine receiving imperial offerings). Its name is also documented in the Engishiki Jinmeicho, an ancient register of shrines from the Heian period. The current main hall is a significant historical structure, rebuilt in 1528. Furthermore, local legends from the Go-Toba Emperor era speak of a divine light descending from the sky, leading to its veneration as 'Hirai Daimyojin' (The Great Deity of Descent).
The centerpiece of the shrine grounds is the historic main hall, featuring a beautiful copper-plated roof that reflects the architectural elegance of its time. A major highlight for visitors is the Yabusame (traditional horseback archery) ceremony. Held twice a year in spring and autumn, this ritual allows spectators to witness the intense and disciplined art of traditional Japanese archery from horseback up close. The shrine grounds are also adorned with various stone lanterns and monuments, such as the Dewa Sanzan Memorial Tower, creating a serene and culturally rich atmosphere.
To fully enjoy the changing scenery and cultural depth, it is highly recommended to visit during the seasonal festival periods. The Yabusame ceremonies in spring and autumn offer a much deeper cultural experience than a standard visit. Specifically, the ceremony held on November 3rd (Culture Day) in autumn attracts many visitors due to its authenticity and scale. Visiting during daylight hours allows you to better observe the harmony between the shrine's architecture and the surrounding natural beauty.
Visitors can witness the spectacular Yabusame, a traditional martial art where archers shoot arrows while riding horses. This is a significant ritual dedicated to the deities. By timing your visit with the spring or autumn schedules, you can immerse yourself in the atmosphere of a historic Japanese festival. Additionally, you can obtain a Goshuin (sacred temple seal/stamp) at the shrine office as a meaningful souvenir of your spiritual journey.
The shrine is nestled in a lush, natural environment at the foot of Mt. Garyu. While the surrounding area includes residential neighborhoods and medical facilities, the shrine itself remains a peaceful and tranquil sanctuary. It is easily accessible from JR Morosawa Station on the Hachiko Line, making it a perfect spot for a relaxing stroll through nature and history.
When visiting, please maintain a respectful attitude toward the sacred space. If you wish to receive a Goshuin, ensure you visit the shrine office during its operating hours. Since many traditional rituals and transactions involve cash, it is highly recommended to carry Japanese Yen. As the shrine is surrounded by nature and features historical structures, comfortable walking shoes are recommended for navigating the grounds.
