History
[
edit
]
The area of Yamaguchi was part of the ancient
Su? Province
. During the
Muromachi period
it was ruled by the
?uchi clan
, who at their height ruled over six provinces in the
Chugoku region
of western Japan. The ?uchi clan claimed descent from the royal house of
Baekje
and grew wealthy due to extensive trade with Korea and
Ming Dynasty
China. After the
Onin War
, they welcomed intellectuals who escaped from
Kyoto
, such that Yamaguchi prospered as a center of culture. Later in the Muromachi period, Christian missionaries from Spain and Portugal were welcomed, and the area became an early center for the
Kirishitan
faith. The ?uchi were eventually overthrown by their vassals, the
M?ri clan
, who ruled the area as part of
Ch?sh? Domain
during the
Edo Period
.
Following the
Meiji Restoration
, the town of Yamaguchi was established within
Yoshiki District, Yamaguchi
with the creation of the modern municipalities system on April 1, 1889. On April 1, 1905 Yamaguchi annexed the village of Kami-unorei, followed by Shimo-unorei on July 1, 1915. On April 10, 1929: The town of Yamaguchi absorbed the village of Yoshiki to create the city of Yamaguchi.
Yamaguchi annexed the village of Miyano on April 1, 1941. On April 1, 1944, Yamaguchi annexed towns of Og?ri and Ajisu, and the villages of Hirakawa, ?toshi, Sue, Natajima, Aiofutajima, Kagawa and Sayama (all from Yoshiki District.)
The town of
Ajisu
separated from Yamaguchi on November 23, 1947, followed by the town of
Og?ri
on November 1, 1949. Yamaguchi annexed the town of ?uchi on May 1, 1963 and the village of Suzenji on November 3, 1963. On October 1, 2005 Yamaguchi merged with town of
Tokuji
(from
Saba District
), and the towns of
Aio
,
Ajisu
and
Og?ri
(all from Yoshiki District);. Yoshiki District was dissolved as a result of this merger. On January 16, 2010 Yamaguchi absorbed the town of
At?
(from
Abu District
).
Government
[
edit
]
Yamaguchi has a
mayor-council
form of government with a directly elected mayor and a
unicameral
city council of 35 members. Yamaguchi contributes six members to the Yamaguchi Prefectural Assembly. In terms of national politics, the city is divided between the
Yamaguchi 1st district
and the
