The history of this area involves powerful clans and changing borders. Before the Meiji Restoration, the land was divided into two provinces. These were Echigo Province on the mainland and Sado Province. During the Sengoku period, the Nagao clan ruled from Kasugayama Castle. A notable leader was Nagao Kagetora. He later became known as Uesugi Kenshin. He unified the leaders of Echigo Province. He also became the head of the Uesugi clan.

Later, the city of Niigata became a vital port. It was the first port on the Sea of Japan to open to foreign trade. This happened after Matthew Perry opened Japan to the world. Since then, it has traded with Russia and Korea.

Nature and geography define the daily life of the prefecture. The Shinano River flows through this region. It is the longest river in Japan. Large parts of the land are protected. About 25% of the land is in Natural Parks. These include Bandai-Asahi, Chūbu-Sangaku, Nikkō, and Oze National Parks.

Other protected areas are the Echigo Sanzan-Tadami and Sado-Yahiko-Yoneyama Quasi-National Parks. There are also thirteen Prefectural Natural Parks. The landscape can be harsh.
