Ninomaru and Honmaru Palaces

Ninomaru Palace and Honmaru Palace are located in Nijo Castle.

Nijo Castle was built by Ieyasu, the first of the Tokugawa shoguns, as an administrative center and symbol of power.  

His residence was completed in 1603 while the Fushimi Momoyama Castle south of Kyoto remained the headquarters of the state. It was meant to impress all with the power and wealth of the Tokugawa. It is remembered as well as being the place that the last Tokugawa shogun surrendered power to the 15-year-old Meiji Emperor in 1867.
