Niigata Prefecture (Niigata Prefecture) is the Chubu region of Japan.
A prefecture located in the Hokuriku region and Koshinetsu region. The prefectural office is located in Niigata City.
Facing the Sea of Japan, the prefecture is generally divided into four regions, Joetsu region, Chuetsu region, Kaetsu region, and Sado region from a geographical point of view (see below in #Regional division).
The area is the fifth largest in 47 prefectures, and the length of the coastline is 634.0 kilometers (Honshu 331.0 kilometers, Sado Island 279.9 kilometers, Awashima 23.1 kilometers).
In ancient times, it was the territory of Echigo, occupying the eastern half of the Hokuriku Expressway of the Gokishichido, and in the province of Japan (former country), it corresponds to the entire area of Echigo and Sado. From this old country name, it is sometimes expressed as Essa.

Prefectural emblem The prefectural emblem is made by placing a broken "new" character in the center and surrounding it with a round design of "play".

The entire prefecture has a climate on the Sea of Japan side, and is designated as a heavy snowfall area (some special heavy snowfall areas). The amount of snowfall and snowfall in the mountains is one of the largest in the world. In Tsunan Town, Tokamachi City, Uonuma City, etc., the average snow depth exceeds 2 m even in urban areas, and in Matsunoyama, Tokamachi City, the snowfall exceeds 4 m. Depth is also often observed. In addition, it is said that there was a snow depth of 818 cm in February 1927 in the Itakuraku village of Joetsu city, which is said to be the highest record in the village. On the other hand, the amount of snow in coastal areas such as Kashiwazaki City and Niigata City is not so great (see Geography of Niigata City # Snow for details).
Due to the warm current of the Sea of Japan (Tsushima Current), the winter temperature is high for the latitude, and radiative cooling is unlikely to occur due to the short daylight hours, so it does not cool much in the morning and evening. Therefore, the snow that falls has a lot of water and is heavy in nature.
The average summer temperature is not particularly high compared to other regions, but abnormally high temperatures may be observed during the typhoon season due to the foehn phenomenon. On September 3, 2020, we observed temperatures above 40 ° C, the highest in Japan for September, in Sanjo City and Tainai City, and on August 15, 2019, the number in the prefecture such as Itoigawa City and Sado City Aikawa. The lowest temperature did not fall below 30 ° C at the point, which was the highest record for the lowest temperature in Japan.
