The Kantō region (関東地方 Kantō-chihō) is a geographical area of Honshu, the largest island of Japan.[1] The region includes the Greater Tokyo Area and encompasses seven prefectures: Gunma, Tochigi, Ibaraki, Saitama, Tokyo, Chiba, and Kanagawa. Within its boundaries, slightly more than 45 percent of the land area is the Kantō Plain. The rest consists of the hills and mountains that form the land borders. In official census count on October 1, 2010 by the Japan Statistics Bureau, the population was 42,607,376[2] amounting to approximately one third of the total population of Japan.

The heartland of feudal power during the Kamakura period and again in the Edo period, Kantō became the center of modern development. Within the Greater Tokyo Area and especially the Tokyo-Yokohama metropolitan area, Kantō 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 Kantō 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 Taisho period: the Great Kantō 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, 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 Honshū are situated on the Kantō plain. These include Naval Air Facility Atsugi, Yokota Air Base, Yokosuka Naval Base, and Camp Zama.

The name Kantō literally means "East of the Barrier". The name Kantō is nowadays generally considered to mean the region east (東) of the Hakone checkpoint (関所). An antonym of Kantō, "West of the Barrier" means Kansai region, which lies western Honshu and was the center of feudal Japan.

After the Great Kantō earthquake many people in Kantō 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.

North and South

The most often used subdivision of the region is dividing it to "North Kantō" (北関東 Kita-Kantō), consisting of Ibaraki, Tochigi, and Gunma Prefectures, and "South Kantō" (南関東 Minami-Kantō), 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.[3]

The Japanese House of Representatives' divides it into the North Kantō (北関東 Kita-Kantō) electorate which consists of Ibaraki, Tochigi, Gunma and Saitama Prefectures, Tokyo electorate, and the South Kantō (南関東 Minami-Kantō) electorate which consists of Chiba, Kanagawa and Yamanashi Prefectures. (Note that Yamanashi is out of Kantō region in the orthodox definition.)

East and West

This division is not often but sometimes used.

  • East Kantō (東関東 Higashi-Kantō): Ibaraki, Tochigi and Chiba Prefectures.
  • West Kantō (西関東 Nishi-Kantō): Gunma, Saitama, Tokyo, Kanagawa (and sometimes Yamanashi) Prefectures.

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.

  • Inland Kantō (関東内陸部 Kantō nairiku-bu): Tochigi, Gunma, Saitama (and sometimes Yamanashi) Prefectures.
  • Coastal Kantō (関東沿岸部 Kantō engan-bu): Ibaraki, Chiba, Tokyo and Kanagawa Prefectures.

Greater Kantō

The Japanese national government defines the National Capital Region (首都圏 Shuto-ken) as Kantō region plus Yamanashi Prefecture. Japan's national public broadcaster NHK uses Kantō-kō-shin-etsu (関東甲信越) involving Yamanashi, Nagano and Niigata Prefectures for regional programming and administration.


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.

In popular culture

  • In the Pokémon franchise, a region named and designed after Kantō is the first geographical setting of both the anime and the game series (it was featured in Pokémon Red, Green, Blue, and Yellow; FireRed and LeafGreen; Gold, Silver, and Crystal; and HeartGold and SoulSilver).
  • In the anime Death Note, the main story takes place in the Kantō region of Japan after it was deduced that the serial killer, Kira, was residing there.
  • The post-apocalyptic anime Desert Punk takes place in a region known as "The Great Kantō Desert", which is assumed to be the Kantō region after a mysterious nuclear incident.
  • The anime Kill la Kill takes place in Kantō, with Honnō-ji being the main setting. The series makes numerous references to the Kantō region, especially in the Tri-City Schools Raid.
  • In James Clavell's novel Shōgun, the Kantō region is featured as a contentious territory for vying daimyos and is source for part of the novel's plot development.
