via Wikipedia: Kōchi, Kōchi · see source
Kōchi, the capital of Kōchi Prefecture, is situated on the southern coast of Shikoku Island, facing the Pacific Ocean. The city’s geography is divided into three distinct sections: a narrow alluvial plain at the head of Urado Bay, which forms the urban core and is crossed by the Kagami and Kokubu rivers; a mountainous northern region, where the highest point is Mount Kuishi at 1,176 meters; and a hilly southern area around Urado Bay and a strip of coastline, which houses port-related industry and residential zones. The city experiences a very wet humid subtropical climate, receiving roughly twice the rainfall of Shikoku’s other major cities, Matsuyama and Takamatsu, and is the most typhoon-prone major city in Japan due to its direct exposure to the open Pacific. Historically, the area was part of ancient Tosa Province. The river plain was first settled as a castle town after Yamauchi Kazutoyo chose the site for Kōchi Castle in 1601, replacing earlier seats of the Chōsokabe clan. The city’s name comes from the castle. During the Meiji Restoration, Kōchi became known as a center for pro-imperial ideology and later for incubating democratic and human rights movements. It was incorporated as a modern municipality on April 1, 1889. A tram service began in 1904, and the city connected to the national rail network in 1951. On July 3, 1945, during World War II, 129 U.S. aircraft dropped 1,060 tons of incendiary bombs, destroying 48% of built-up areas, killing 401 civilians, and leaving over 40,000 homeless. Kōchi was designated Shikoku’s first core city on April 1, 1998. Subsequent mergers incorporated the villages of Kagami and Tosayama in 2005, and the town of Haruno in 2008. The city’s population grew rapidly in the 1960s and 1970s, peaked around 2000, and has since declined.

Lore & Background
Kōchi was originally settled as a castle town around Kōchi Castle, built in 1601 by Yamauchi Kazutoyo to replace the earlier seats of the Chōsokabe clan. The city takes its name from that of the castle. During the Meiji Restoration, Kōchi became famous as a centre of pro-imperial ideology, and later for incubating democratic and human rights movements. The city was incorporated on April 1, 1889, with the establishment of the modern municipalities system. Tram service began on May 2, 1904, and the city was connected to the national rail network on November 12, 1951. On July 3, 1945, at 6:22 pm (JST), 129 aircraft took off to bomb Kōchi. 1,060 tons of incendiary bombs were dropped, destroying 48% of the built up areas of the city, killing 401 civilians and rendering over 40,000 homeless. The city was designated as the first core city on Shikoku on April 1, 1998. It expanded through mergers: the villages of Kagami and Tosayama on January 1, 2005, and the town of Haruno on January 1, 2008. Kōchi has a mayor-council form of government with a directly elected mayor and a unicameral city council of 42 members. The current mayor since 2023 is Ryugo Kuwana. The city is home to two universities, Kōchi University (national) and University of Kochi (prefectural). Its most famous dish is katsuo tataki, made by lightly searing and seasoning bonito.
