Kawagoe Castle 3.13

Kawagoe Castle is a flatland Japanese castle in the city of Kawagoe, in Japan's Saitama Prefecture. It is the closest castle to Tokyo to be accessible to visitors, as Edo castle is now the Imperial palace, and largely inaccessible.Along with a number of other castles in the region, Kawagoe saw much action in the 15th-16th centuries, as the Hōjō clan and two branches of the Uesugi clan vied for control of the Kantō region. In the 1450s, Kawagoe was held by the Yamanouchi branch of the Uesugi; the Ogigayatsu branch controlled nearby Shirai castle in Shimōsa Province, and the newly built Edo castle, which significantly bolstered their tactical advantages over their Yamanouchi cousins.Decades later, when the Hōjō clan sought to gain control of the Kantō, Kawagoe served as an important base of operations. Hōjō Ujitsuna seized it in 1537, and took Edo castle in 1524. For roughly two decades after that, the Uesugi launched a number of attempts to regain the region; in the 1545 battle of Kawagoe, the Hōjō garrison of Kawagoe defeated an attempted siege of Edo castle; this victory would lead to the end of Uesugi power in the region, and the near-total destruction of that clan.
