Numata Castle was located in Numata City, Gunma Pref. It is said to have been built by Bankisai Akiyasu, the 12th generation head of the Numata clan. The castle was called Kurauchi Castle in those days. As it stands at the strategic spot on the way to Kanto region, a lot of battles to capture this castle were fought among warring lords such as the Uesugi clan of Echigo region (present-day Niigata Pref.), the Hojo clan of Odawara, and the Takeda clan of Kai province (present-day Yamanashi Pref.). In the Edo period, this area came under control of the Sanada clan. Sanada Yukinobu started its modification work in 1597, and in several years it was modified into an early modern-styled castle with the five-story donjon, Ninomaru (the second castle), Sannomaru (the third castle), and the stone walls, which were rear for Kanto region. At the present time, only a part of stone walls and moats remains, which remind us of the ancient times. In spring, a 400-year-old cherry tree called “Goten-zakura (palace cherry tree)” is in full bloom. It looks as if it were talking of rise and fall of the castle.
