Ube is part of ancient
Nagato Province. The
Kotozaki Hachiman-gu shrine dates from the
Heian period and the local Koto clan, a branch of the
Mononobe clan dominated the area into the
Kamakura period. The area became part of the holdings of the
Ōuchi clan in the
Muromachi period and subsequently part of
Chōshū Domain under the
Mōri clan under the
Edo period Tokugawa shogunate. The village of Ube (宇部村) was established within
Asa District, Yamaguchi with the creation of the modern municipalities system on April 1, 1889. Ube was elevated directly to city status on November 1, 1921, in a rare direct elevation from village to city. From April to August 1945, 254 people were killed, 557 were injured, and 68 were missing due to eight
air raids during
World War II. The scale of the air raid on July 2 was particularly large, and most of the central part of the city was destroyed by fire. In the air raid on July 29, three mock
atomic bombs were dropped. Previously a
coal mining town, the city has developed an effective policy to improve its environment. In particular it has combated the problem of
air pollution and its success in doing so saw it being recognised by the
United Nations Environment Programme as among UNEP's Global 500 Roll of Honour in 1997. On November 1, 2004, the town of
Kusunoki (from
Asa District) was merged into Ube. This brought the city to its current extent, together with previous municipal mergers (
Fujiyama in 1931,
Kōnan in 1941,
NishKiwa in 1943, Great Shōwa mergers/1954:
Kotō,
Futamatase,
Ono,
Higashi-Kiwa). ==Government==
