Under the seclusion policy, foreign trades were mainly limited to those with China at the Chinese residential area in Nagasaki, and with the Netherlands at Dejima island, but also through Tsushima Domain, trade with Yi Dynasty of Korea was authorized by the shogunate government at the consular office (wakan).
貿易は鎖国政策を布いていたために、主流は長崎市の唐人屋敷における中国、出島におけるオランダとの交易であるが、対馬藩を仲介した李氏朝鮮との倭館での交易も幕府の公認を受けたものだった。
