How did the Tokugawa shogunate isolate Japan?
Thank you for you question Restriction of trade Restriction of religion Restriction of literature… Foreigners who attempted to land or who were shipwrecked were put to death. The actions of foreign governments were not so much aimed at opening Japan to trade (the country actually possessed little of commercial value for traders. But Japan sits on an important sea lane to China; and the Americans (in particular) wanted those lanes open. That’s why the fates of sailors were so important to them.
