Kantō region shares border with Chūbu region
Geography
The surface geology of the Kanto 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 900m in Hakone, about 800m in Tanzawa and Takao, about 700m in Okutama, Oku Musashi and Oku Chichibu, about 600m in Nishijoshu, Akagiyama, Ashio Mountains and Tsukuba Mountains and about 500m 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, Mt. Yamizo, and Mt. The Kanto 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 Kanto 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 Kanto (Kanto, Tohoku, 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).
