Ryukyu enjoyed a booming trade with Southeast Asia and Korea, and traded many goods from these countries with China, either as tributary gifts or as regular trade goods. Beginning in 1609, when Ryukyu was invaded by Japan's Satsuma Domain, its trade with Southeast Asia and Korea all but came to an end, replaced by commerce with Satsuma. For roughly five hundred years, from 1372 until the mid-19th century, a small number of Ryukyuans resided in Fuzhou and Beijing at any given time, studying academic classics and various arts as well. The community of scholars in Kumemura, on Okinawa, also included a number of skilled artists and craftsmen. Thus, given the changes in Ryukyu's relationships with foreign countries over its history, it is easy to see why Ryukyuan lacquer prior to the 17th century shows strong Chinese, Korean and Southeast Asian influences, while objects produced after the Japanese invasion evidence far stronger Japanese influences.
