Contact between Europe and Japan changed during the time of Japan's Tokugawa dynasty with the implementation of strict isolationist policies and the expulsion of most Europeans from Japan, except for the Dutch who were allowed to trade through the port city of Nagasaki.
The contact between Europe and Japan during the time of Japan's Tokugawa dynasty underwent significant changes. Initially, contact was limited to the Portuguese and the Spanish, who introduced Christianity to Japan.
However, as the Tokugawa shogunate sought to consolidate its power and prevent foreign influence, it implemented strict isolationist policies known as the Sakoku policy. This resulted in the expulsion of most Europeans from Japan, with the exception of the Dutch who were allowed to trade through the port city of Nagasaki under strict regulations.
