Iwakiyama Shrine, located at the foot of the sacred Mt. Iwaki in Hirosaki City, Aomori Prefecture, is an ancient shrine affectionately known as “O-Iwa-sama” or “O-yama” by the people of Tsugaru. With a long and distinguished history spanning over 1200 years since its founding, it has been revered as the Ichinomiya (first-ranked shrine) of Tsugaru Province. This article comprehensively introduces information you should know before visiting Iwakiyama Shrine, including its history, highlights, blessings, and access methods.
History and Origins of Iwakiyama Shrine
An Ancient Shrine with Over 1200 Years of History
The origins of Iwakiyama Shrine date back approximately 1200 years. It is believed to have begun in 780 AD (Hoki 11), when a shrine building was constructed on the summit of Mt. Iwaki. Mount Iwaki, an isolated peak, stands at 1625 meters, making it the highest peak in Aomori Prefecture. Its beautiful conical shape has earned it the nickname “Tsugaru Fuji.”
Long ago, it was revered as an object of mountain worship, with Mount Iwaki itself being worshipped as a sacred object. Visible from all over Tsugaru, Mount Iwaki has been intimately intertwined with the lives of the people of Tsugaru, providing water to irrigate fields, protecting apples from the wind like a screen, and assisting fishermen as a lighthouse.
Construction and Protection by Successive Lords
Despite experiencing several fires, Iwakiyama Shrine was carefully protected by successive lords of the Hirosaki domain. Many of the existing structures date from the early to mid-Edo period.
- Kanei 5 (1628): The main gate was constructed.
- Kanei 17 (1640): The worship hall was constructed.
- Genroku 7 (1694): The main shrine, inner gate, and sacred fence were constructed.
These structures are valuable as examples of shrine architecture at the northernmost tip of Honshu. They utilize cypress wood from Aomori Prefecture, and some have withstood the elements for 390 years. Currently, the main gate, worship hall, main shrine, inner gate, and sacred fence are all designated as important national cultural properties.
Status as the Ichinomiya (First Shrine) of Tsugaru Province
Iwaki-yama Shrine has long been revered as the Ichinomiya (first shrine) of Tsugaru Province. It is a central place of worship, serving as the guardian deity of agriculture and fishing, the god of Tsugaru’s development, and the dwelling place of the ancestral spirits of the local people. Its former shrine rank was Kokuhei Shosha (National Shrine of the Lower Rank), and it has maintained its religious and cultural importance in the Tsugaru region since the Meiji era.
Highlights and Buildings within the Shrine Grounds
The Magnificent Shrine Buildings Known as “Oku-Nikko”
The greatest highlight of Iwaki-yama Shrine is its magnificent group of shrine buildings, so beautiful that it has earned the nickname “Oku-Nikko” (the inner Nikko). Boasting a splendor comparable to Nikko Toshogu Shrine, the buildings, adorned with colorful carvings, are breathtakingly beautiful.
The shrine buildings are solidly constructed, and the intricate carvings throughout showcase the excellent techniques of the Edo period. The harmonious beauty of the vermilion paint, gold leaf, and vibrant decorations continues to captivate visitors.
The Gate Tower and Approach
The approach to Iwaki-yama Shrine is enveloped in a solemn atmosphere surrounded by giant cedar trees. As you proceed along the approach, the first thing you see is the gate tower, built in 1628. Its imposing two-story structure possesses a dignity befitting an entrance to a sacred area. Passing through the main gate, you’ll find another gate, followed by the worship hall and the main sanctuary. This arrangement, while adhering to traditional shrine architecture, exudes a unique solemnity characteristic of Iwaki-san Shrine.
Distinctive Upward-Facing Komainu (Guardian Lion-Dogs)
Within the shrine grounds are the rare “upward-facing komainu,” a rarity nationwide. While typical komainu face forward, those at Iwaki-san Shrine are characterized by their upward gaze, as if looking up to the heavens. It’s said that they are either gazing up at the inner shrine at the summit of Mount Iwaki, or gazing up to the gods of heaven.
These unique komainu are a popular photo spot, with many visitors taking commemorative photos.
Three-Headed Dragon Water Basin
Particularly striking within the shrine grounds is the water basin shaped like a three-headed dragon. The clear water gushing from the mouths of the three dragon deities is spring water from Mount Iwaki, and can be used not only for purifying hands but also for drinking.
This sacred water is believed to bring blessings for fertility, and many worshippers drink it to absorb its power into their bodies. The cold, pure water allows one to feel the sacred energy of Mount Iwaki.
Main Shrine, Inner Gate, and Sacred Fence
Behind the worship hall is the main shrine, built in 1694 (Genroku 7). The main shrine is a building adorned with intricate carvings and decorations, and is designated as an Important Cultural Property. The inner gate and sacred fence surrounding the main shrine were also constructed around the same time, and together they create a solemn atmosphere for the sacred area.
These structures were built by combining the wealth and technical expertise of the Hirosaki Domain, and can be considered the pinnacle of shrine architecture in the Tsugaru region.
Treasures such as Hanging Lanterns and Japanese Swords
Numerous treasures, such as hanging lanterns and Japanese swords, donated by successive feudal lords and devotees, are preserved within the shrine grounds and buildings. These are valuable cultural assets that tell the story of Iwakiyama Shrine’s long history and the deep faith of its people.

Oyama Sankei (Mountain Pilgrimage)
A Traditional Tsugaru Event
The most important event at Iwaki-yama Shrine is the “Oyama Sankei,” held primarily on the first day of the eighth month of the lunar calendar. This is a group pilgrimage to Mount Iwaki, a unique Tsugaru religious event praying for a bountiful harvest and family safety.
Participants, clad in white robes, ascend Mount Iwaki chanting “Saigi Saigi, Dokkoisa.” This chant means “Saigi” (lucky tree), signifying the climb in search of a tree that brings happiness.
A Form of Faith Continuing in Modern Times
Oyama Sankei remains a grand event attracting many participants even today. This year, the festival is scheduled to be held on September 9th (Mukoyama), 10th (Yoiyama), and 11th (Tsuitachiyama), demonstrating the deep faith of the people of Tsugaru.
The sight of people climbing the mountain at night, carrying torches, is fantastical and a beloved autumn tradition in Tsugaru.
Inner Shrine at the Summit of Mt. Iwaki
The inner shrine of Iwakiyama Shrine is located near the summit of Mt. Iwaki. Climbing to the 1625-meter-high summit is not easy, but many people aim for the inner shrine during pilgrimages to the mountain and during the climbing season.
The view from the summit is spectacular, offering panoramic views of the Tsugaru Plain, the Sea of Japan, and on clear days, even Hokkaido. It is believed that visiting the inner shrine brings even greater blessings.
