The Japanese pirates refer to the pirates who invaded and plundered the coastal areas of China and Korea in the 6th century14-/kloc-0. Apart from coastal looting, they mainly engaged in smuggling trade between China and Japan. During the War of Resistance against Japanese Aggression period, China people also called Japanese pirates Japanese invaders.

Historically, the sources of Japanese pirates are very extensive and their components are particularly complex. Japanese pirates dominated in the early stage, and people from China and other East Asian countries dominated in the later stage. Japanese pirates are called "real pirates" and non-Japanese are called "fake pirates".

"Biography of Ming History and Japan" records: "In May (the thirty-second year of Jiajing), the Japanese pirates reunited, suddenly invaded Jiaxing, and reached the king, with the aim of hitting more than 1,900 levels and going out to Zhelin. Other Japanese troops plundered Suzhou and extended to Jiangyin and Wuxi, entering and leaving Taihu Lake. About three tenths, seven tenths. "

Ming history made it very clear that this time the Japanese were 30% true and 70% false.

During the Ming Dynasty, under the influence of Japan's closed-door policy, some "ronin" of Kyushu island owners sought lucrative international trade under the ban. When the "Japanese pirates" arrived in the coastal ports of China, they traded when there were business opportunities, and plundered when they were unprepared. Hu Zongxian, Yu, Qi Jiguang and other famous anti-Japanese soldiers worked hard to clean up the coastal areas of Zhejiang and Fujian. But the parties are well aware that among the Japanese pirates, besides the "real Japanese", there are also China people and westerners.
