### Rivers

The Kokai River flows northeast of the city, the Kinugawa River west of the city, and the Tone River south of the city, which used to be a cove. Although the city and most of the city area were located on a plateau, flood damage was often observed in the low-lying areas because the city was surrounded by rivers on three sides. However, the danger has gradually decreased since the Meiji Era (1868-1912) with the construction of levees and regulating reservoirs, as well as the relocation of houses within the regulating areas. Large-scale flooding did not occur until around 1982, and the inundation itself was over by 1985. Today, only a few areas are considered potentially inundated due to flooding and improvement of inundated areas. In addition, since the area was surrounded by rivers, it benefited from the river boat transportation developed since the Edo period, and became a relay point from the lower reaches of the Tone River, such as Choushi, to Sekiyado and the Edogawa River area, and a concentration point for products from the northern Kanto region via the Kinugawa River.
