Tokugawa Ieyasu was a SAMURAI who established the Edo Shogunate.
He lived away from home, as a hostage when he was a child.
Even after he became independent, he had a lot of difficulties, because he came under the rule of Oda Nobunaga and Toyotomi Hideyoshi.
However, he endured the hard time and achieved Japan's unification at last.
He established the Edo Shogunate and yielded his son the Shougun's post.
The Edo Shogunate governed Japan for 300 years.
Moreover, Tokugawa Ieyasu is known also that he preferred to take self-prepared medicine.
Although we are not sure that it was the reason, he lived long very much for the samurai in those days.
