Yamaguchi Prefecture (山口県, Yamaguchi-ken) is a prefecture of Japan located in the Chūgoku region of Honshu.[2] Yamaguchi Prefecture has a population of 1,377,631 (1 February 2018) and has a geographic area of 6,112 km2 (2,359 sq mi). Yamaguchi Prefecture borders Shimane Prefecture to the north and Hiroshima Prefecture to the northeast.
Yamaguchi Prefecture was created by the merger of the provinces of Suō and Nagato.[4] During the rise of the samurai class during the Heian and Kamakura Periods (794–1333), the Ouchi family of Suō Province and the Koto family of Nagato Province gained influence as powerful warrior clans. In the Muromachi period (1336—1573), Ouchi Hiroyo, the 24th ruler of the Ouchi family conquered both areas of Yamaguchi Prefecture. The Ouchi clan imitated the city planning of Kyoto. They gained great wealth through cultural imports from the continent and trade with Korea and Ming Dynasty China. As a result, Yamaguchi came to be known as the "Kyoto of the West," and Ouchi culture flourished. Sue Harutaka defeated the 31st ruler of the Ouchi clan. The Sue clan was then defeated by Mōri Motonari, and the Mōri family gained control of the Chūgoku region. Yamaguchi was ruled as part of the Mōri clan domain during the Sengoku period. Mōri Terumoto was then defeated by Tokugawa Ieyasu in the battle of Sekigahara in 1600. He was forced to give up all his land except for the Suō and Nagato areas (current-day Yamaguchi Prefecture), where he built his castle in Hagi. Mōri sought to strengthen the economic base of the region and increase local production with his Three Whites campaign (salt, rice, and paper).
After Commodore Matthew Perry's opening of Japan, clans from Nagato (also called Chōshū) played a key role in the fall of the Tokugawa shogunate and the establishment of the new imperial government.
Four years after the Edo Shogunate was overthrown and the Meiji government formed in 1868, the present Yamaguchi Prefecture was established. The Meiji government brought in many new systems and modern policies, and promoted the introduction of modern industry, though the prefecture was still centered on agriculture during this period. In the Taishō period, from 1912 to 1926, shipbuilding, chemical, machinery, and metal working plants were built in Yamaguchi's harbors in the Seto Inland Sea area. During the post-World War II Shōwa Period, Yamaguchi developed into one of the most industrialized prefectures in the country due to the establishment of petrochemical complexes.[5]
For the purposes of development analysis, Yamaguchi is construed to be part of Northern Kyushu. Although Yamaguchi is not part of the island of Kyushu, it has become a functional satellite of the Kanmon Straits metropolitan area.[7]

Tourism
The most popular place for tourism is Shimonoseki, which has the Karato Fish Market and a large fireworks festival in summer.
Another attraction is the Kintai Bridge in the town of Iwakuni. This five-arched wooden structure is considered a symbol of Western Honshū. The area on the banks of the Nishiki river close to the bridge is considered among the best places in Japan for Hanami, when groups of family and friends gather in early April to view cherry blossoms.
Hagi City is in the north of Yamaguchi. It is a very traditional city. The usual color of Japanese post boxes is red, but in Hagi they are painted green or brown. The Hagi Museum is modeled after a traditional samurai residence. The exhibits are detailed and realistic, and are changed every year. The permanent collection is data about Hagi's history and collections about Takasugi Shinsaku. Hagi also contains a reverberatory furnace which has been designated a World Heritage Site.[10]
Kawara soba (hot tile noodles) is a popular dish in Yamaguchi. It was developed during the Seinan Rebellion when soldiers cooked wild grass and meat on hot tiles. Today people in Yamaguchi create this dish by frying green tea noodles on a hot tile, and arranging a thin fried egg, stewed beef, green onions, and grilled liver on top.
Ferries from Shimonoseki Port International Terminal
Two ferry services provide regular sea transport from the Shimonoseki Port International Terminal: Kanpu Ferry provides round-trip service to Busan, South Korea; the Orient Ferry provides round-trip service to Qingdao and Shanghai, respectively.
Since the Meiji Restoration in which lower-rank nobility from Chōshū played a major role, many politicians from Yamaguchi have held important positions in national politics. In the post-war era, the most prominent political family from Yamaguchi is the Kishi-Abe/Satō prime ministerial dynasty, and Yamaguchi is leaning solidly towards the Liberal Democratic Party (LDP).

Since the electoral reform of the 1990s, Yamaguchi elects four members directly to the House of Representatives. Three of the new single-member districts have been held exclusively by Liberal Democrats as of 2013, the easternmost district bordering Hiroshima was initially won by Shinji Satō (Eisaku Satō's son) in 1996, but went to DemocratHideo Hiraoka in several later elections.

The seat for the 4th district was held by former prime minister Shinzo Abe until his assassination in 2022, and is currently vacant. For the proportional representation segment of the House of Representatives, Yamaguchi forms part of the Chūgoku block.
In the House of Councillors, Yamaguchi is represented by two members, making it one of the currently 31 winner-take-all single-member districts. As of 2013, the two members are Yoshimasa Hayashi (LDP, 4th term, up in 2019), agriculture minister in the 2nd Abe Cabinet, and following the April 2013 by-election to replace Nobuo Kishi, Kiyoshi Ejima (LDP, 1st term, up in 2016), former mayor of Shimonoseki city.
