The prefecture is generally divided into four geographical areas: Joetsu in the south, Chuetsu in the centre, Kaetsu in the north, and Sado Island. The mouth of the Shinano River, the longest river in Japan, is located in Niigata Prefecture. Niigata city is the largest city on the Japan Sea coast. [2]


Niigata City features a humid subtropical climate. The climate in Niigata City is characterized by its high humidity and strong winds from the Sea of Japan. While many other parts of Niigata Prefecture tend to have heavy snow, Niigata City itself usually receives less due to its low-lying elevation and the shielding effect of Sado Island.
