The century-long presence of Catholic traders and missionaries in Japan ended in the 1630s when Iemitsu ordered the expulsion of nearly every European from the country. European access to trade relations with Japan was restricted to one Dutch ship each year. Iemitsu's policies on this matter were reinforced after the execution of two Portuguese men who came to plead for the re-establishment of Japan's earlier foreign trade policy. By the end of the 1630s, Iemitsu had issued a series of edicts more extensively detailing a system of restrictions on the flow of people, goods, and information in and out of the country.
