Chiba

The name of Chiba in the Japanese language is formed from two kanji characters. The first, 千, means "thousand" and the second, 葉 means "leaves". The name first appears as an ancient kuni no miyatsuko, or regional command office, as Chiha no Kuni no Miyatsuko (千葉国造). The name was adopted by a branch of the Taira clan, which moved to the area in present-day Chiba City in the late Heian period. The branch of the Taira adopted the name and became the Chiba clan, which held strong influence over the area of the prefecture until the Azuchi–Momoyama period. The name "Chiba" was chosen for Chiba Prefecture at the time of its creation in 1873 by the Assembly of Prefectural Governors (地方官会議, Chihō Kankai Kaigi), an early Meiji-period body of prefectural governors that met to decide the structure of local and regional administration in Japan.

The first records related to the city of Chiba record the emigration of Taira Tsuneshige (1083?–1088), a powerful bushi warlord of the late Heian period, to Shimōsa Province, which historically occupied the north of Chiba Prefecture. Tsuneshige was appointed as gunji administrator of Sōma District, but was transferred to the same position in Chiba District two years later. Here he proclaimed himself Chiba Tsuneshige (千葉常重), became a kokushi governor of the province, and used the area around present-day Chiba City as a power base to rule over Shimōsa Province, Kazusa Province, as well as establish himself as a military force in the Kantō region. Tsuneshige's son, Chiba Tsunetane (千葉常胤) (1118–1201) was instrumental in aiding Minamoto no Yoritomo (1147–1199) with the establishment of the Kamakura shogunate. …
