History. The heartland of feudal power during the Kamakura period and again in the Edo period, Kanto became the center of modern development. Within the Greater Tokyo Area and especially the Tokyo-Yokohama metropolitan area, Kanto houses not only Japan's seat of government but also the nation's largest group of universities and cultural institutions, the greatest population and a large industrial zone. Although most of the Kanto plain is  used for residential, commercial or industrial construction, it is still farmed. Rice is the principal crop, although the zone around Tokyo and Yokohama has been landscaped to grow garden produce for the metropolitan market. A watershed moment of Japan's modern history took place in the late Taishō period: the Great Kanto earthquake of 1923. The quake, which claimed more than 100,000 lives and ravaged the Tokyo and Yokohama areas, occurred at a time when Japan was still reeling from the economic recession in reaction to the high-flying years during World War I. Operation Coronet, part of Operation Downfall , the proposed Allied invasion of Japan during World War II, was scheduled to land at the Kantō plain. Most of the United States military bases on the island of Honshu are situated on the Kantō plain. These include Naval Air Facility Atsugi, Yokota Air Base, Yokosuka Naval Base, and Camp Zama. The name Kanto literally means "East of the Barrier". The name "Kanto" is nowadays generally considered to mean the region east (東) of the Hakone checkpoint (関所). An antonym of Kanto, "West of the Barrier" means Kansai region, which lies western Honshu and was the center of feudal Japan . After the Great Kanto earthquake many people in Kanto started creating art with different varieties of colors. They made art of earthquake and small towns to symbolize the small towns destroyed in the quake. Subdivisions. North and South. The most often used subdivision of the region is dividing it to , consisting of Ibaraki, Tochigi, and Gunma Prefectures, and , consisting of Saitama (sometimes classified North), Chiba, the Tokyo Metropolis (sometimes singulated), and Kanagawa Prefectures. South Kantō is often regarded as synonymous with the Greater Tokyo Area. As part of Japan's attempts to predict earthquakes, an area roughly corresponding to South  Kantō has been designated an 'Area of Intensified Observation' by the Coordinating Committee for Earthquake Prediction. The Japanese House of Representatives' divides it into the electorate which consists of Ibaraki, Tochigi, Gunma and Saitama Prefectures, Tokyo electorate, and the electorate which consists of Chiba, Kanagawa and Yamanashi Prefectures. (Note that Yamanashi is out of Kantō region in the orthodox definition.) Keirin's consists of Chiba, Kanagawa and Shizuoka Prefectures. East and West. This division is not often but sometimes used. Inland and Coastal. This division is sometimes used in economics and geography. The border can be modified if the topography  is taken for prefectural boundaries. Greater Kantō. The Japanese national government defines the as Kantō region plus Yamanashi Prefecture. Japan's national public broadcaster NHK uses involving Yamanashi, Nagano and Niigata Prefectures for regional programming and administration. Cities. The Kantō region is the most highly developed, urbanized, and industrialized part of Japan. Tokyo and Yokohama form a single industrial complex with a concentration of light and heavy industry along Tokyo Bay. Other major cities in the area include Kawasaki (in Kanagawa Prefecture); Saitama (in Saitama Prefecture); and Chiba (in Chiba Prefecture). Smaller cities, farther away from the coast, house substantial  light and automotive industries. The average population density reached 1,192 persons per square kilometer in 1991. Economy. The Kantō region largely corresponds to the Tokyo metropolitan area with the exception that it does not contain Yamanashi prefecture. The Tokyo metropolitan area has the largest city economy in the world and is one of the major global center of trade and commerce along with New York City, Los Angeles, Shanghai, Paris, Seoul and London. Source GDP (purchasing power parity). The agglomeration of Tokyo is the world's largest economy, with the largest gross metropolitan product at purchasing power parity (PPP) in  the world according to a study by PricewaterhouseCoopers. Population. The population of Kanto region is very similar to that of Greater Tokyo Area except that it does not contain Yamanashi Prefecture and contains the rural populations throughout the region. Per Japanese census data, and Kanto region's population has continuously grown but the population growth rate has slowed since early 1992. The Kanto region at 2018 has a population at around 43.3 million people.
