Mt. Iwaki
Hirosaki, Aomori Prefecture, Japan
Rising 1,625 meters above Aomori Prefecture, Mount Iwaki dominates the Tsugaru region as its highest peak and spiritual guardian. Called 'Oiwaki-sama' by locals and 'Tsugaru Fuji' for its symmetrical beauty, this mountain has received worship since before Japanese settlement—the indigenous Emishi people first recognized its sacred nature. The Oyama Sankei pilgrimage, continuing for centuries, remains a living expression of regional faith.

Mount Iwaki's sacred history extends from pre-Japanese Emishi veneration through 1,200 years of documented worship at Iwakiyama Shrine, with the Oyama Sankei pilgrimage continuing as living tradition.
Origin Story
Before Japanese settlers arrived around 780 CE, the indigenous Emishi people venerated Mount Iwaki as a sacred mountain where ancestral spirits resided. When Japanese control was established, Iwakiyama Shrine formalized this existing worship rather than importing new traditions. The shrine has maintained continuous operation for over 1,200 years, with the Tsugaru feudal lords becoming important patrons. The Oyama Sankei pilgrimage developed during the Genroku era (17th-18th century), establishing the three-day August festival that continues today.
