Tokugawa Iemitsu

Tokugawa Iemitsu was born in 1604. He had a fierce rivalry with his brother, Tokugawa Tadanga. He decided to close Japan to most foreigners in 1630's when he had to deal with christian uprisings starting in 1549. Only a few traders were allowed into a small port town to trade with the Japanese and if a Japanese person left Japan he would not be allowed back in.
