About a century and a half ago, Japan was in the Edo period and Japanese politics and society was governed by Edo bakuufu(shogunate) also known as Tokugawa bakufu(shogunate). Edo bakufu was a feudal system of samurai government established by Ieyasu Tokugawa. That’s way it’s called as Tokugawa bakufu.

Ieyasu Tokugawa was one of warlords in the period of the warring states in Japan. He conquered Japan after many civil wars and turned out to be a Japanese authority. Tokugawa shogunate lasted about 265 years and only Tokugawa family had been allowed to play a role as dynasty during the period.
