The area of Usa was the southeastern tip of the former Buzen Province and on the border with the former Bungo Province. The name "Usa" appears in the Kojiki and Nihon Shoki and Emperor Jimmu visited Usa prior to departing to the east for his conquest of Yamato. Due to the economic and political power of Usa Jingū, no samurai clan was able to dominate the area until the Sengoku period during which time it became a battleground between the Ōuchi clan and Ōtomo clan and later the Shimazu clan. Under Toyotomi Hideyoshi, Buzen province became the territory of Kuroda Yoshitaka, who constructed Nakatsu Castle. During the Edo period it was mostly tenryō administered directly by the Tokugawa shogunate, with smaller areas under control of Nakatsu Domain, Shimabara Domain and Usa Jingū. After the Meiji restoration, the town of Usa within Usa District, Ōita was established on May 1, 1889 with the creation of the modern municipalities system. On April 1, 1955 Kitsuki merged with the villages of Yasaka, Kita-Kitsuki and, Nakarie and was raised to city status. On October 1, 2005 Kitsuki merged with the town of Yamaka from Hayami District and the village of Ota from Nishikunisaki District, Ōita. On April 1, 1967 Usa merged with the towns of Ekigawa, Yokkaichi, and Nagasu to form the city of Usa. On March 31, 2005, the towns of Ajimu and Innai (both from Usa District) were merged into Usa.
During World War II, the Usa Naval Air Group (宇佐海軍航空隊, Usa Kaigun Koukūtai) was stationed at an airbase in Usa. Towards the end of the war, the airbase was used to launch kamikaze attacks against American forces. It was subject to B-29 air raids in 1945 which led to the destruction of many of the airfield's facilities and caused the deaths of many soldiers and civilians.[5] Many remnants of the former airfield are still visible. For example, there are several concrete bunkers which once held A6M Zero fighter aircraft. There is also a crater called the "bomb pond" which was caused by a bomb from an American B-29 bomber.[5]
Usa has a mayor-council form of government with a directly elected mayor and a unicameral city council of 21 members. Usa contributes three members to the Ōita Prefectural Assembly. In terms of national politics, the city is part of the Ōita 3rd district of the lower house of the Diet of Japan.
The economy of Usa remains largely agricultural. It has close economic ties with neighboring Nakatsu, and belongs to the urban employment area (10% commuting area) of the Nakatsu metropolitan area.
Usa has 24 public elementary schools and seven public junior high schools operated by the city government and three public high schools operated by the Ōita Prefectural Board of Education. The city also has one private high school.
There have been claims that products made in this town and exported to the US as early as the 1930s carried the label "MADE IN USA", for it to appear as if the product was made in the United States. There are reports that the name of the town was changed to "USA" for this purpose. The aforementioned claims are false. The city had this name long before the 1960s. Usa is a city and products must be labeled by country of origin, making it highly improbable that this would be an adequate loophole. In addition, any products being imported to the U.S. marked as being "made in USA" would have been flagged.[7]
