Kantō region

The Kantō regional governors' association (関東地方知事会, Kantō chihō chijikai) assembles the prefectural governors of Ibaraki, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa, Yamanashi, Nagano and Shizuoka.[5][6]

In the police organization of Japan, the National Police Agency's supervisory office for Kantō (関東管区警察局, Kantō kanku keisatsu-kyoku) is responsible for the Prefectural police departments of Ibaraki, Tochigi, Gunma, Saitama, Chiba, Kanagawa, Niigata, Yamanashi, Nagano and Shizuoka.[7] Tokyo is not part of Kantō or any NPA region, its police has a dedicated liaison office with the national agency of its own.

The Kantō Regional Development Bureau (関東地方整備局, Kantō chihō seibi-kyoku) of the Ministry of Land, Infrastructure, Transport and Tourism in the national government is responsible for eight prefectures generally (Ibaraki, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa, Yamanashi) and parts of the waterways in two others (Nagano and Shizuoka).[8] The Kanto Bureau of Economy, Trade and Industry (関東経済産業局, Kantō keizai-sangyō-kyoku) is responsible for eleven prefectures: Ibaraki, Tochigi, Gunma, Saitama, Chiba, Tokyo, Kanagawa, Niigata, Yamanashi, Nagano and Shizuoka.[9]

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.

In the first Pokémon games, Pokémon Red and Pokémon Blue or Pocket Monsters Red and Pocket Monsters Green as it is known in Japan, the region the player explores is called the Kanto region.

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 kilometre in 1991.

The Kantō region largely corresponds to 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.
