Aira, Kagoshima
is a city located in Kagoshima Prefecture, Japan. It is located west of Kirishima and north of Kagoshima.

The modern city of Aira was established on March 23, 2010, from the merger of the former town of Aira, absorbing the towns of Kajiki and Kamō (all from Aira District).

As of October 1, 2020, the city has a population of 76,405 and a population density of 330.3 persons per km². The total area is 231.32 km².

It is accessed with the Kyushu Expressway at interchange 25, the Kajiki Interchange and interchange 26, the Aira Interchange. The expressway passed through Aira, connecting Kagoshima to the west and Kirishima to the North. The interchange was first opened on December 13, 1973. There are five railway stations in the city. From east to west, Kajiki, Kinkō, Chōsa, Aira and Shigetomi stations serve the city. All of these stations belong to Nippō Main Line, and are operated by Kyushu Railway Company (JR Kyushu).

Aira's claim to fame is a stone gate in the village of Yamada which commemorates the victory of the Russo-Japanese War.

The plan for the merger of the three towns was defeated twice. Once in 2005 and again in 2008. These defeats were due to a debt in public finance and the number of seats in the city council. Finally, in 2009, town representatives compromised with these problems and the merger plan was accepted. Aira District will be left with one municipality.
