Conurbation
The Taiheiyō Belt is the largest conurbation in Japan in every sense, extending from Ibaraki Prefecture to Fukuoka Prefecture, running almost 1,200 km, with the total population of 82.9 million. However, it is rarely referred to in Japan itself with each Prefecture maintaining separate identities. The Greater Tokyo Area, also called Shutoken (the National Capital Region), is a metropolitan area in the Kantō region, with the estimated population of 35,676,000 in 2007, often referred to as the most populous and economically largest metropolitan area in the world.
