Saitama Prefecture contains the administrative territorial entity Chichibu
History
According to Sendai Kuji Hongi (Kujiki), Chichibu was one of 137 provinces during the reign of Emperor Sujin. Chichibu Province was in western Saitama.
The area that would become Saitama Prefecture in the 19th century is part of Musashi Province in the Ritsuryō (or ryō-system; ritsu stands for the penal code, ryō for the administrative code) Imperial administration of antiquity (see Provinces of Japan and the 5 (go) capital area provinces (ki)/7 (shichi) circuits (dō) system) which was nominally revived in the Meiji restoration but has lost much of its administrative function since the Middle Ages. Saitama District (Saitama-gun) was one of Musashi's 21 ritsuryō districts.
In the fifth year of the Keiun era (708), deposits of copper were reported to have been found in the Chichibu District of what is now Saitama Prefecture.
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 daimyōs ruled small domains within the Saitama area.
At the end of the early modern Edo period, large parts of present-day Saitama were part of the shogunate domain (baku-ryō) or the often subsumed holdings of smaller vassals (hatamoto-ryō) around Edo, major areas were part of the fiefdoms (-han) Kawagoe (ruled by Matsui/Matsudaira, fudai), Oshi (Okudaira-Matsudaira, fudai) and Iwatsuki (Ōoka, fudai); few territories were held by domains seated in other provinces.
