Fukuoka–Kitakyushu
Fukuoka-Kitakyushu Greater Metropolitan Region (福岡・北九州大都市圏, Fukuoka Kitakyūshū Daitoshiken) is the most common name given to the region comprising the metropolitan areas of the cities of Fukuoka and Kitakyushu in Fukuoka Prefecture, Japan and in between. Alternate names are many, including Kitakyushu-Fukuoka Greater Metropolitan Region (北九州・福岡大都市圏), Northern Part of Kyushu Greater Metropolitan Region (北部九州大都市圏) One reason for complications in naming is because the whole region itself was once referred to as "Kitakyushu", which had become ambiguous after the city merger in 1963 which created the city by the same name.
