The plateau consists of uplifted reef limestones of Paleozoic age, which were thickened by overfolding during the Akiyoshidai orogenic movement. Subsequent erosion has created an undulating karst landscape dimpled with many dolines and countless limestone pinnacles up to two meters in height. Beneath the surface lie hundreds of caves, a few of them quite significant geologically.
Numerous fossils of Pleistocene age have been found in these caves, including those of the Japanese rhinoceros, Stegodont elephant, Naumann elephant, Young tiger, and numerous other animals from the last interglacial period.
The area around Akiyoshidai was once heavily forested about 500,000 years ago. In the Jōmon period, the area served as a hunting ground and the bottoms of sinkholes as vegetable fields. Numerous Japanese Paleolithic artifacts have been recovered. As farming began in Japan, the local people eventually replaced the forested landscape with Japanese pampas grass for feeding their animals and thatching houses. Repeated cycles of burning the grass have kept trees from growing back since.
The area of Mine was part of ancient Nagato Province and was part of Chōshū Domain under the Edo Period Tokugawa shogunate. After the Meiji restoration, the area was divided into 13 villages within Mine District, Yamaguchi with the creation of the modern municipalities system. The village of Ota was raised to village status on August 1, 1923, followed by Isa on January 1, 1924 and Omine on May 1, 1939. The city of Mine was created by the merger of Isa and Omine with the villages of Ofuku, Nishiatsu and Higashiatsu on March 31, 1954. On October 1 of the same year, the town of Ota merged with the villages of Ayagi, Managata Agago to form the town of Mitō. The remainder of the district was consolidated into the town of Shūhō on April 1, 1955. On March 21, 2008, Mine absorbed Mitō and Shūhō, and the newly merged city retained the name, Mine.
Mine has a mayor-council form of government with a directly elected mayor and a unicameral city council of 16 members. Mine contributes one member to the Yamaguchi Prefectural Assembly. In terms of national politics, the city is part of the Yamaguchi 3rd district of the lower house of the Diet of Japan.
Mine was noted from ancient times for its copper mines with the Naganobori Copper Mine supplying the copper used in the construction of the Nara Daibutsu and Nara period Wadōkaichin coins. Mine developed as an industrial city due to the production of anthracite and limestone from the Ōmine Coal Field after the Meiji Restoration. After the mines were closed, the population decreased sharply and the city has been active in attracting industrial parks.
Tourism centered on Akiyoshidai Quasi-National Park is also a major component of the local economy.
Mine has 12 public elementary school and six public junior high schools operated by the city government, and one public high school operated by the Yamaguchi Prefectural Board of Education. There are also one private high school.
