Wako where Japanese pirates from approximately 900 to 1600 AD. They operated in the seas around Japan, Korea, China and south-east Asia. The name Wako was originally Chinese, Wa meant both dwarfs and Japanese and Ko meant Pirates. Actually the Wako were criminal clans that ranged from Japanese buccaneers to Chinese raiders to Korean ex-navalists. At certain times the Wako clans managed to invade the coast of Korea, China and Taiwan. Some Daimyos created Wako clans to raid on their behalf and in exchange for protection and legality of their actions they had to pay a portion of the spoils to the Daimyo.
In my next post I will tell you a story about the early Wako.
