Throughout the year, the entire Kanto Plain, especially the inland areas, are easily affected by radiative cooling due to clear skies and north winds, so the minimum temperature before sunrise can drop to about 5 degrees below zero in winter.

184-588: The Kanto basin-forming movement, which has continued since the Neogene period . This movement is what caused sedimentation in the center of the present-day Kanto Plain and uplift of the surrounding mountains. As a result, sediment from the surrounding mountains was deposited very thickly (the Tertiary layer reaches as high as 3,000 meters) and further uplifted to form many hills and plateaus. Large tectonic lines such as

368-544: The eastern margin of the Fossa Magna and the Median Tectonic Line are thought to exist in the central part of the plain, but this thick accumulation of soft sedimentary layers makes it difficult to find active faults that can cause earthquakes (faults exist in the base 3000m below the sedimentary layers). In addition, natural sediments such as sediment carried by rivers have been used to create land, and
391-569: The north and Mounts Hakone and Fuji to the southwest, are thought to have been deposited on these plateaus. Among the plateaus, the Musashino Plateau has the largest stretch of land, extending from the western edge of Ōme to the eastern edge of Yamanote , which borders the alluvial plains of the Arakawa and Sumida Rivers. Its elevation gradually declines from west to east, measuring 190 m at Ōme and 20 m at Yamanote. Hills in
414-543: The northern part. Due to the influence of the Black Current (warm current) flowing along the coast, the climate is mild, especially in the southern part. In summer, rainfall is heavy due to the rainy season front caused by monsoon, and typhoons are often seen.

460-605: The sensory temperature is lower than the actual temperature. The lowest temperatures in central Tokyo are higher than those in surrounding areas due to the heat island effect. Kumagaya tends to get hotter because of being inland, foehn phenomenon, which occurs when the wind in the sky above blows down after crossing the mountains on the north and west sides of the Kanto Plain, and the sea breeze that warms up while passing through central Tokyo.

In winter, the monsoon from the Sea of Japan is blocked by the Mikuni Mountains, and the moisture falls as snow along the mountains to the north, and the monsoon that has lost its moisture blows through the Kanto Plain as a strong gale carrying dry air (such as Akagi Orosi in Gunma Prefecture , Tsukuba Orosi in Ibaraki Prefecuture and Futaara Orosi). Snowfall has been decreasing year by year, but snow accumulation of around 10–20 cm
