Matsuida Castle
is the remains of a castle structure in Annaka, Gunma Prefecture, Japan. After Go-Hōjō's army defeated Takigawa Kazumasu's  army in the Battle of Shintsugawa, Matsuida Castle was seized and controlled by the Go-Hōjō clan. Daidōji Masashige expanded and improved the defences of the castle against a possible invasion of the Toyotomi clan. In 1590, after the outbreak of the Siege of Odawara, the castle was besieged by a big army of the Toyotomi clan and attacked by Maeda Toshiie , Uesugi Kagekatsu and Sanada Masayuki. Masashige surrendered after about a month of siege. Its ruins have been protected as a Town designated historic site. References
