The surface geology of the Kantō Plain is the Quaternary alluvium and diluvium. The low mountain vegetation at an altitude of about 500 to 900 m in and around the plain is an evergreen broad-leaved forest zone. The distribution height range of laurel forests is 900 m in Hakone, about 800 m in Tanzawa and Takao, about 700 m in Okutama, Oku Musashi and Oku Chichibu, about 600 m in Nishijoshu, Akagiyama, Ashio Mountains and Tsukuba Mountains and about 500 m in Kitage and Nasu Mountains. Over the evergreen broad-leaved forest are deciduous broad-leaved forests such as beech, birch, and Quercus crispula. In addition, coniferous forests such as Abies veitchii and Betula ermanii spread above the deciduous broad-leaved forest from an altitude of about 1100 m higher than the lower limit of the deciduous broad-leaved forest. Mountains are spread out such as the Taishaku Mountains, Mt. Takahara, Mt. Nasu, and Mt. Yamizo. The Kantō Plain, which is the largest plain in Japan. Just north of the Enna Hills is Japan's largest alluvial fan Nasuno at the foot of Mt. The Kujukuri Plain. The southern part of Chiba Prefecture is the Boso hills. The area around Kasumigaura in Ibaraki Prefecture is the Joso plateau and Hitachi plateau. Gunma Prefecture and the Chichibu region of Saitama Prefecture are basins. Rivers such as the Arakawa and Edo rivers pour into Tokyo Bay, and the Kinugawa and Tone rivers flow into the Pacific Ocean in Inubōsaki. Tokyo Bay is surrounded by the Boso Peninsula and the Miura Peninsula, facing the west side of Chiba Prefecture, a part of Tokyo and the east side of Kanagawa Prefecture, and borders the Pacific Ocean from Uraga Suido. The coastal area is an industrial area. The south side of Kanagawa Prefecture faces Sagami Bay and Sagami Nada. The southern coast of Ibaraki Prefecture faces Kashima Nada. The Sagami Trough, which was the epicenter of the two Kantō earthquakes, passes through Sagami Bay. Efforts are being made to take safety measures against earthquakes in various places. The highest point is the summit of Mt. Nikko-Shirane (Mt. Oku-Shirane) on the border between Nikko City, Tochigi Prefecture and Katashina Village, Gunma Prefecture. It is the eighth highest point in Japan's prefectures. It is also the highest point north of Kantō (Kantō, Tōhoku, Hokkaido). The highest points of the prefectures are Mt. Sanpo (2,483 m) in Saitama, Mt. Kumotori (2,017 m) in Tokyo, Mt. Hiru (1,673 m) in Kanagawa, Mt. Yamizo (1,022 m) in Ibaraki, and Mt. Atago (408 m) in Chiba. Atagoyama in Chiba Prefecture is the lowest among the highest peaks in each prefecture. The region experiences a humid subtropical climate with a summer to fall precipitation maximum (Cfa/Cwa). == History ==

The name Kantō literally means "East of the Barrier". The name Kantō is nowadays generally considered to mean the region east () of the Hakone Barrier (). The antonym of Kantō is the Kansai region meaning "West of the Barrier", which lies in western Honshu and was the center of feudal Japan. in the Kantō region Kamakura was the political capital during the Kamakura period and it served as the seat of the Kamakura shogunate from 1185 to 1333, established by Minamoto no Yoritomo. in Kamakura This was the first military government in Japan's history. Kamakura flourished until the fall of the Kamakura Shogunate, and its political functions returned to Kyoto in 1392. In 1591, Tokugawa Ieyasu gave up control of his five provinces (Mikawa, Tōtōmi, Suruga, Shinano, and Kai) and moved all his soldiers and vassals to his new eight provinces in the Kantō region. The proclamation of this decision happened on the same day Toyotomi Hideyoshi, the de facto ruler of Japan at that time, entered Odawara castle following the surrender of the Hōjō clan after the Siege of Odawara (1590). The governors of Kantō region under Ieyasu rule: Ieyasu established his personal new seat of power on Edo town, which at that time was an underdeveloped town in Kantō. In the Edo period, Kantō became the center of modern development. Within the Greater Tokyo Area and especially the Tokyo-Yokohama metropolitan area, the Kantō plain 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, some land 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. Operation Coronet, part of Operation Downfall, the proposed Allied invasion of Japan during World War II, was scheduled to land on the Kantō Plain. Great earthquake of 1923 A watershed moment of Japan's modern history took place in the late Taishō period: the Great Kantō earthquake of 1923. The quake, which claimed more than 100,000 lives and ravaged Greater Tokyo area, occurred at a time when Japan was still reeling from the economic recession in reaction to the high-flying years during World War I. After the 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. == 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, 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 the 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. • : Ibaraki, Tochigi, and Chiba prefectures. • : Gunma, Saitama, Tokyo, Kanagawa (and sometimes Yamanashi) prefectures.

The border can be modified if the topography is taken for prefectural boundaries. • : Tochigi, Gunma, Saitama (and sometimes Yamanashi) prefectures. • : Ibaraki, Chiba, Tokyo, and Kanagawa prefectures. Greater Kantō The Japanese national government defines the as the Kantō region plus Yamanashi Prefecture.

The population of Kantō region is very similar to that of the Greater Tokyo Area except that it does not contain Yamanashi Prefecture and contains the rural populations throughout the region. Per Japanese census data, and the Kantō region's data, population has continuously grown but the population growth rate has slowed since early 1992. The Kantō region at the 2020 census had a population of 43.65 million people. == See also ==
