Geographyedit

Nagaoka is in the center of Niigata prefecture and the surrounding Chūetsu region of Japan, between longitude 138°E and latitude 37°N. It is 80 minutes from Tokyo by way of the Joetsu Shinkansen or three hours on the Kan-Etsu Expressway and is considered a strategic traffic point in the region. Nagaoka was an inland city until January 1, 2006, when the city merged with four municipalities; two were touching the Sea of Japan. The Shinano River flows through the city from south to north and industrial development is on both banks of the river. The Higashiyama mountain range lies to the east.
