Hidetada Closes Japan
As for the daimyo, Hidetada continued Ieyasu's methods in dealing with them, and he controlled them strictly. His father, just before his death, had suggested that he should keep the daimyo at Edo for three years. Hidetada preferred to send them to their domains for a year and recall them later, so that if one of them were to refuse to obey, he would attack him immediately and so eliminate him. However, he did not need to go to this extreme.
