Built in : 1601
Designer: Date Masanume
Sendai Castle is located on the Aoba Mountain. It was naturally protected by the cliff and Hirose River. Date Masamune who is Daimyo of Sendai designed this castle. Most of the building were lost during WWII. Right now, there are stone walls and Otemon Gate are rebuilt.
Sendai Castle is very unique compare to other Castle. Otemon Gate which is the main entrance of the castle is located between Honmaru and Ninomaru, and Sannomaru is located out side of Otemon Gate. Because Honmaru is located on the top of the mountain, House of Date families are located in Sannomaru. So, Honmaru take the style of Mountain Castle, and Sannomaru is Land Castle.
The castle was one of the nerve centers of the Ouetsu Reppan Domei during the Boshin War, when Date Yoshikuni was lord of Sendai. Taken over by the new government in the aftermath of Sendai's surrender, it was partially dismantled in the 1870s.
