Battle of Miyajima

The 1555 Battle of Miyajima (厳島合戦, Itsukushima Kassen) was the only battle to be fought on the sacred island of Miyajima; the entire island is considered to be a Shinto shrine, and no birth or death is allowed on the island. Extensive purification rituals took place after the battle, to cleanse the shrine and the island of the pollution of death.
