Geography

Nagaoka is located 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 3 hours on the Kan-Etsu Expressway. Nagaoka was an inland city until January 1, 2006, when the city merged with four municipalities-two were touching the Sea of Japan. The current Nagaoka now touches the Sea of Japan on the north and after the merger, it is still considered a strategic traffic point in the region. The Shinano River flows through it from south to north and industrial development occurs on both banks of the river. The Higashiyama mountain range lies to the east.

History
The area of present-day Nagaoka was part of ancient Echigo Province. Under the Tokugawa shogunate, a castle town was constructed by Hori Naoyori lord of Nagaoka Domain in 1616. However, as the initial castle was located in an area prone to flooding by the Shinano River, a new castle was built at the site of present-day Nagaoka Station in 1617. Nagaoka flourished as under the reign of the 13 generations of the Makino clan during the Edo period. In the Boshin War of 1868 during the Meiji Restoration, the city was reduced to rubble. A gift of one hundred sacks of rice from a neighboring province was sold to finance a new school during the reconstruction of Nagaoka, from which the anecdote of Kome Hyappyo was born.
The towns of Nagaoka and Nagaoka-honmachi were established with the creation of the municipalities system on April 1, 1889. The two towns were merged on November 1, 1901 with the towns of Senju, Kusouzu, Ara, and village of Ouchi to form the modern town of Nagaoka, which was then raised to city status on April 1, 1906.
