Kojū

Kojū [三優; こじゅう] is a city located in northern Aoma Prefecture to the due north of Aoma city. As of 2020, it had an estimated population of roughly 39,000.
Kojū is the location of a large military base, Kojū Air Base, which is under the operation of the Kanton Air Self-Defense Force. It is also an important base for signals intelligence and related activities. The estimated 6,000-7,000 military personnel and their dependents stationed at Kojū Air Base are not included in the city's population figures.
Kojū is located on the plains beneath the Aomaki Hills, most of the city being flatland. The nearest large settlement is Aoma, which is 30-40 minutes away by car. The surrounding area is mostly rural and scenic, with the Jūsaki Falls to the north of the city being a popular sightseeing spot. Like most inland cities in Aoma, Kojū is affected by heavy blizzards and ice during the winter months.
Kojū serves as a regional industrial and commercial center, with agriculture and commercial fishing playing secondary roles in the local economy. The large military presence at Kojū Air Base also makes an impact on the city's economy.
Kojū is also known as being the birthplace of the great writer Ami Monyama [1935-1983], who was born in the city.
