History

Picture of annual event of the Nagaoka castle – going into the castle for New Year greeting

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, Nagaoka Domain was a member of the Ōuetsu Reppan Dōmei against the imperial forces, and the city was reduced to rubble during the Battle of Hokuetsu. 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.[citation needed]

With the Meiji period creation of the modern municipalities system on April 1, 1889, the towns of Nagaoka and Nagaoka-honmachi were established. 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.
