Kawasaki is a city located in Kanagawa Prefecture, Japan, between Tokyo and Yokohama. It is the 9th most populated city in Japan and one of the main cities forming the Greater Tokyo Area and Keihin Industrial Area. Kawasaki occupies a belt of land stretching about 30 km along the south bank of the Tama River, which divides it from Tokyo. The eastern end of the belt, centered around JR Kawasaki Station, is flat and largely consists of industrial zones and densely built working-class housing, the Western end mountainous and more suburban. The coastline of Tokyo Bay is occupied by vast heavy industrial complexes built on reclaimed land. Its name is made of kawa = "river" and saki = "small peninsula" or "department".
