About Akagi Shrine
History and Origins of Akagi Shrine
Akagi Shrine is one of Gunma Prefecture’s most representative shrines, and has long been revered as the center of mountain worship with Akagi Mountain as its sacred body. Multiple Akagi Shrines exist on Akagi Mountain, with the following three being the most well-known:
- Sanyo-sawa Akagi Shrine (Sanyo-sawa-cho, Maebashi): Considered the main shrine of Akagi Shrine, with the oldest history
- Oohora Akagi Shrine (Fujimi-cho, Maebashi): A beautiful shrine situated on the shores of Lake Onuma on Akagi Mountain
- Nonomiya Akagi Shrine (Ninomiya-cho, Maebashi): Known as the Second Shrine of Kozuke Province
All of these shrines are surrounded by the abundant nature of Akagi Mountain, with clear spring water existing in their vicinity.
Natural Environment of Akagi Mountain
Akagi Mountain is a composite volcano with its highest peak at Kurogane Mountain at an elevation of 1,828 meters, featuring caldera lakes such as Lake Onuma and Lake Konuma, a naturally rich mountain. The terrain formed by volcanic activity stores abundant groundwater, which emerges as spring water at various locations on the mountain slopes.
Akagi Mountain receives approximately 1,500mm of annual precipitation. This abundant rainwater and snowmelt passes through volcanic geological layers, becoming clear spring water containing mineral content.
Characteristics of Akagi Shrine’s Spring Water
Water Quality and Composition
The spring water surrounding Akagi Shrine has the following characteristics, as it slowly permeates through volcanic geological layers:
Water Quality Characteristics:
- Water temperature: Stable at approximately 10-14°C year-round

- Hardness: Soft water to moderately hard water
- Transparency: Extremely high and crystal clear
Contained Mineral Components:
