Akihasan Hongu Akiha Jinja

The shrine's museum holds swords offered by legendary warlords Takeda Shingen, Toyotomi Hideyoshi, and Katō Kiyomasa, who sought the fire god's protection before battle.

Visitors purify themselves by striking flint to create sparks, a ritual called kiribi. This fire-based purification replaced the traditional water fountain during COVID and stuck around.

In 1685, the government banned the shrine's riotous mikoshi procession along the Tōkaidō highway. The ban backfired spectacularly, spreading the Akiha cult and leading to 800 branch shrines across Japan.

Akihasan Hongu Akiha Jinja is the head shrine of about 800 Akiha shrines across Japan.
