The Battle of Dan-no-ura was a major sea battle of the Genpei War, occurring at Dan-no-ura, in the Kanmon Straits off the southern tip of Honshū. On April 25, 1185, the fleet of the Minomoto ('Genji') clan, led by general Minamoto no Yoshitsune, defeated the fleet of the Taira clan (Heike). The morning rip tide was an advantage for the Taira, but turned to their disadvantage in the afternoon. The young Emperor Antoku was one of those who died among the Taira nobles.
