naval battles of a very large scale, fought between japanese clans and involving more than 1000 warships, are recorded from the 12th century. the decisive battle of the genpei war, and one of the most famous and important naval battles in pre-modern japanese history, was the 1185 battle of dan-no-ura, which was fought between the fleets of the minamoto and taira clans. these battles consisted first of long-range archery exchanges, then giving way to hand-to-hand combat with swords and daggers. ships were used largely as floating platforms for what were largely land-based melee tactics.
