During the Ming dynasty, Japan became decentralized without a central government and with many local daimyo reigning the country, in what would be called the Sengoku Period. Many of these daimyo encouraged Chinese immigration to Japan due to their skills and boost to the local economy. Many Chinese communities would be established in Japan, especially on the island of Kyushu. Many Chinese pirates would set up their bases in Japan in order to launch raid and attacks on mainland China as part of the wokou. For example, the powerful Chinese pirate, Wang Zhi, who became known as the "king of the wokou", established his base of operation in Japanese islands, in order to launch raids against the Ming government. Many of the Chinese pirates were supported by Japanese daimyo themselves.
