Red seal ships (朱印船 Shuinsen) were Japanese armed merchant sailing ships bound for Southeast Asian ports with a red-sealed patent issued by the early Tokugawa shogunate in the first half of the 17th century. Between 1600 and 1635, more than 350 Japanese ships went overseas under this permit system.
Origins
From the 13th to the 16th century, Japanese ships were quite active in Asian waters, often in the role of "Wakō" pirates who plundered the coast of the Chinese Empire. Official trading missions were also sent to China, such as the Tenryūjibune around 1341. Wakō activity was efficiently curbed in 1588 with the interdiction of piracy by Hideyoshi. (more…)
