Geography
A wide area of green farmland, Minuma Rice Paddies, forms the central part of the ward. The major river system includes the Shiba River, the Ayanose River, and the Minuma Irrigational Canal. In the southern section of the ward runs the Tōhoku Expressway.
The first people who stayed permanently in this area are considered to have arrived approximately twenty five thousand years ago. Paleolithic archaeological sites found in the area include Matsuki (松木), Wadakita (和田北), Kitajukunishi (北宿西), and Mamiya Miyaushiro (間宮宮後). In the early modern period, the area witnessed large-scale civil engineering projects: the construction of the Minuma Reservoir (見沼溜井, Minuma Tamei), the demolition of the reservoir, and the creation of the Minuma Irrigational Canal (見沼代用水, Minumadai Yōsui). Daimon-shuku (大門宿) became one of the post stations of the Nikkō Onari Kaidō.[2]
The villages of Tanida (谷田), Omagi (尾間木), Mimuro (三室), and Daimon (大門) were created within Kitaadachi District, Saitama with the establishment of the municipalities system on April 1, 1889. On April 1, 1932, Tanida was annexed by Urawa Town, which was elevated to city status on February 11, 1934. Omagi, Mimuro and Daimon merged to form the village of Misono on April 1, 1956. Misono was subsequently divided between Urawa and Kawaguchi on May 1, 1962. On May 1, 2001, the cities of Urawa, Yono and Ōmiya merged to form the new city of Saitama. When Saitama was proclaimed a designated city in 2003, the much area of corresponding to former villages of Tanida, Omagi, Mimuro and Daimon became Midori Ward.
