Kariwa District, Niigata


Kariwa is a district located in Niigata Prefecture, Japan.
As of July 1, 2019, the district has an estimated population of 4,578 and a density of 174 persons per km². The total area is 26.27 km².
The district was once part of the now-defunct Koshi District until the Heian period when the district was created under the name of Mishima District. Prior to the split, Mishima District covers the cities of Kashiwazaki, village of Kariwa, Nagaoka. When Santō District splits off from Koshi District during the Edo period, Mishima was renamed to Kariwa.
In 1940, the town of Kashiwazaki became a city. After Kashiwazaki merged the surrounding areas, the district continued on to shrink. On April 1, 2005, the town of Oguni merged into the city of Nagaoka and a month later, the towns of Nishiyama and Takayanagi merged into the city of Kashiwazaki. With this merger, Kariwa District has only the village of Kariwa left.
