Saitama Prefecture Kōnosu has a humid subtropical climate (Köppen Cfa) characterized by warm summers and cool winters with light to no snowfall.

The area was a favored falconry site by the Tokugawa shoguns during the Edo period and was also the location of Kōnosu-shuku, a post station on the Nakasendō highway.

The town of Kōnosu was created within Kitaadachi District, Saitama with the establishment of the modern municipalities system on April 1, 1889.

On July 1, 1954, Kōnosu annexed the neighboring villages of Mida, Tamamiya, Mamuro and Kasahara (from Kitasaitama District).

Flower gardening and rice cultivation are also popular, and Kōnosu is also the main production center for traditional dolls used in the Hinamatsuri festival.
