Saitama Prefecture (埼玉県 Saitama-ken) is a prefecture of Japan located in the Kantō region of the island of Honshu. The capital is the city of Saitama.

This prefecture is part of the Greater Tokyo Area, and most of Saitama’s cities can be described as suburbs of Tokyo, to which a large number of residents commute each day.

According to Sendai Kuji Hongi (Kujiki), Chichibu was one of 137 provinces during the reign of Emperor Sujin. Chichibu Province was in Saitama’s western part. The Saitama area was historically known as a fertile agricultural region which produced much of the food for the Kantō region. During the Edo period, many fudai daimyo ruled small domains within the Saitama area.
