The Closed Country Policy (23 dic 1639 año – 23 dic 1853 año)
Descripción:
 1639: "Closed Country Policy"- a way to safely exclude missionaries and merchants
Japan valued European trade but did not like their aggressiveness & ideas
The persecution of Christians was part of an attempt to control foreign ideas
Most contacts with Europe ended:
- only Nagasaki port remained open to foreign traders
- only Dutch & Chinese merchants were allowed into the port
- English had voluntarily left
- Spanish & Portuguese had been expelled
- Tokugawa shoguns controlled Nagasaki: monopoly on foreign trade (still profitable)
Remained closed to Europeans for over 200 years
Japanese were forbidden to leave so that they would not bring back foreign ideas
Japan developed as a self-sufficient country: without European attempts to colonize & establish their presence
Not too many natural resources- wanted to be self-reliant because they did not have much and did not want to rely on other countries
