Chiba (city)

Etymology

The name of Chiba in the Japanese language is formed from two kanji characters. The first, {{linktext|千}}, means "thousand" and the second, {{linktext|葉}} means "leaves". The name first appears as an ancient kuni no miyatsuko, or regional command office, as Chiha no Kuni no Miyatsuko. 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, an early Meiji-period body of prefectural governors that met to decide the structure of local and regional administration in Japan.

History

Early history

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, 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 (1118–1201) was instrumental in aiding Minamoto no Yoritomo (1147–1199) with the establishment of the Kamakura shogunate. Tsuneshige built a spacious residence and numerous temples in present-day Chiba City, and in the same period he transferred his power base from Ōji Castle to a mansion in present-day Chiba City. The area of present-day Chiba City became jōkamachi , or castle town, and prospered under the Chiba clan. The clan's power extended in the region until the Muromachi period.

Medieval period

The Chiba clan's power and influence declined because of wars around the Kantō region during the Nanboku-chō and Muromachi periods. In the 16th century, the Hara clan, which were vassals of Chiba clan, took control of the region from the Chiba clan and built Inohana Castle. In the Sengoku period, the Hara clan was forcibly removed by Ashikaga Yoshiaki (足利義明, not to be confused with 足利義昭). Then, Ashikaga Yoshiaki was also removed by the Sakai (酒井 not to be confused with the Sakai clan in Mikawa) clan, which was one of the servants of the Satomi (里見) clan. Finally both the Chiba and Sakai clans were annihilated by Toyotomi Hideyoshi.

Later history

In the Edo period, the Oyumi, Morikawa clan, and the Sakura clans governed the area now occupied by the city. A part of the area was also governed directly by the Tokugawa Bakufu. The Oyumi clan governed their territory stably. On the other hand, according to the Sakura clan, from the beginning of the Edo period, changed governors frequently, including Takeda Nobuyoshi, Matsudaira Tadateru, Ogasawara Yoshitsugu, and Doi Toshikatsu. Finally the Hotta clan stabilized the governance of their territory. Chiba prospered in this period as a shukuba post-town of the Tokugawa shogunate.

Modern history

After the Meiji Restoration in 1868, Chiba Prefecture was established in 1873 with the merger of Kisarazu Prefecture and Inba Prefecture. The border between Kisarazu and Inba was the location of Chiba Town and was thus chosen as the location of the prefectural government. With the opening of the Sōbu Main Line, Chiba developed rapidly, becoming the political, economic, and cultural capital of Chiba Prefecture. The town of Chiba was established within Chiba District with the creation of the municipalities system on April 1, 1889. Chiba City formed on January 1, 1921. Numerous small villages and towns were merged into the previous town of Chiba, a process that continued until 1944. Large-scale land reclamation added to the area of the city throughout the 20th century. The city was a major center of military production leading up to the Pacific War, and the aerial bombing of Chiba in 1945. The city was almost completely destroyed by the end of the war. Post-war industrialization led to the city becoming a major part of the Keiyō Industrial Zone. Chiba became a Designated City of Japan on April 1, 1992.
