Niigata has a long history as a port and is distinguished for being the site of one of only five international ports opened in 1868 when Japan resumed contact with other countries after nearly 250 years of self-imposed isolation. Since that time, Niigata has developed into one of Japan's most important modern international ports. Niigata has grown into an important regional center of activity, the city has pursued a plan of careful development in order to preserve its traditional culture, natural environment, and distinctive local character. When Niigata is mentioned, many people often think immediately of the area's delicious rice and sake or the city's beautiful sunsets, but the residents of Niigata themselves take pride, rather, in the spirit of hospitality and community that so distinguishes the city.
