Akagi Shrine, Shinto shrine near a lake on Mount Akagi, Gunma Prefecture, Japan
Akagi Shrine is a Shinto sanctuary built on an island in the center of Lake Onuma at Mount Akagi in Gunma Prefecture. The lake itself formed from volcanic activity and creates a water-surrounded setting for the shrine, which features traditional wooden buildings overlooking the water.
The sanctuary was founded in 1300 as a spiritual extension of the original Akagi Shrine located at the mountain's base. This connection between the island sanctuary and the older shrine below shapes the spiritual geography of the entire mountain.
The shrine honors Iwatsutsuo-no-mikoto and Akagihime-no-mikoto, two deities to whom visitors pray for blessings in relationships, protection, and successful childbirth. These deities hold deep meaning in local spiritual life and draw those seeking favor in personal matters.
The best way to reach the sanctuary is by car via Route 4, since it sits in a mountain region where public transportation is limited. Good walking shoes are worth bringing, as there are paths to navigate on the island.
Within the complex stands Keisetsu-jinja, a subordinate shrine dedicated to arts and academics that draws many entertainment industry professionals. This specialized worship space shows how shrines support different professional paths.
