Emperor Go-Yōzei ruled Japan from December 31, 1571 until September 25, 1617.
Tokugawa Ieyasu was the founder and first shogun of the Tokugawa Japanese Empire that ruled from the Battle of Sekigahara in 1600 until the Meiji Restoration of 1668. The Tokugawa Shogunate was, actually, a feudal Japanese military government who ruled from Edo Castle.

The term Shogun resembles an army commander in chief. The legacy of the Shogunate persists. Currently, the head of state in Japan is the Emperor; but the head of government is the Prime Minister. However, the term "Shogun" seems to persist.

When a Prime Minister withdraws, still holds political power with considerable influence, so respectfully nicknamed as "Yami Shogun" or a "shadow shogun", as has happened with Kakuei Tanaka Ichiro Ozawa and recently.
