History of Iwakiyama Shrine | Over 1200 Years of History
Founding and Origins
The founding of Iwakiyama Shrine dates back to 780 AD (Hoki 11). It is believed that the construction of a shrine building on the summit of Mount Iwaki in that year marked its origin. Mount Iwaki, a sacred and divine mountain, has been revered as the god of development in Mutsu-Tsugaru, the guardian deity of agricultural and marine products, and the dwelling place of ancestral spirits.
Mount Iwaki, visible from all over Tsugaru, has bestowed the virtue of compassion upon the people and has been a cornerstone of local life and spiritual support. As an ancient shrine originating from mountain worship, Mount Iwaki itself is an object of worship, and the inner shrine is located at the summit.
From the Medieval to the Early Modern Period
During the medieval period, the shrine developed under the patronage of the rulers of the Tsugaru region. Especially after the Tsugaru clan established the Hirosaki Domain, the shrine received deep reverence from successive feudal lords, and the shrine buildings were constructed and repaired.
The existing shrine buildings were built by the Hirosaki feudal lords from the early to mid-Edo period, and many of them are designated as National Important Cultural Properties.
Modern Era
With the Meiji-era separation of Shinto and Buddhism, Iwaki-yama Shrine, which had previously been a syncretic Shinto-Buddhist shrine, was reorganized as a purely Shinto shrine. In 1871 (Meiji 4), it was ranked as a National Shrine of the lower rank, establishing its status as the Ichinomiya (first-ranked shrine) of Tsugaru Province.
Even today, as a renowned shrine protecting the northern gate, its reverence extends not only within Aomori Prefecture but throughout Japan.
National Important Cultural Property Shrine Buildings | Highlights and Architectural Beauty
The greatest highlight of Iwaki-yama Shrine is the group of shrine buildings designated as National Important Cultural Properties. Six buildings—the Tower Gate, Worship Hall, Main Shrine, Inner Gate, Mizugaki Fence, and Middle Gate—have been designated as Important Cultural Properties, showcasing the pinnacle of Edo period architecture.
Tower Gate (Important Cultural Property)
The first thing you encounter as you proceed along the approach to the shrine is the Tower Gate, built in 1628. This magnificent gate, with its three bays and single entrance, features a hipped roof and copper tile roofing, with striking vermilion pillars and intricate carvings. Hanging lanterns adorn the upper level, creating a solemn atmosphere.
Worship Hall (Important Cultural Property)
After passing through the Tower Gate, the Worship Hall, built in 1640, comes into view. It is a five-bay, three-bay hipped roof structure with a portico at the front. The interior’s coffered ceiling and carved decorations strongly reflect the style of the early Edo period.
Main Shrine (Important Cultural Property)
Built in 1694 (Genroku 7), the main shrine is a three-bay, flowing-style building with a copper tile roof. Located behind the worship hall, its exquisite carvings and the beauty of its vermilion paint are striking. Its magnificent and opulent construction speaks to the wealth and faith of the Hirosaki domain.
Middle Gate, Inner Gate, and Mizugaki (Important Cultural Property)
The middle gate, inner gate, and mizugaki (sacred fence) surrounding the main shrine were also built in 1694. These, together with the main shrine, form a unified space, enhancing the sacredness of the precincts.
Approach and Torii Gates
The approach leading to the shrine is lined with towering cedar trees on both sides, creating a solemn atmosphere. Multiple torii gates stand along the approach, guiding visitors step by step into the sacred precincts. The harmony between the cedar grove and the buildings is particularly beautiful, befitting its nickname, “Oku-Nikko” (Inner Nikko).
Oyama Sankei | A Traditional Tsugaru Event

History and Significance of Oyama Sankei
The origins of Oyama Sankei are ancient and deeply intertwined with the worship of Mount Iwaki. The people of Tsugaru have sought divine protection and communicated with their ancestors by climbing Mount Iwaki, a sacred mountain.
Participants, clad in white robes, ascend from Iwaki-san Shrine to the inner sanctuary at the summit, chanting “Saigi Saigi” and playing mountain climbing music. This scene has become a quintessential symbol of the end of summer in Tsugaru.
