Kirishima-shi is a city located in Kagoshima Prefecture

Kirishima has the second largest population of the cities in Kagoshima Prefecture. It is a crossroads for commerce between Kagoshima and Miyazaki Prefectures. It is also the home of the Kagoshima Airport, the terminus for the JR Hisatsu line, and is served by two major expressways. The former Kokubu-Hayato area was designated as a "Technopolis" as high tech industries such as Sony and Kyocera opened facilities in the city.

The modern city of Kirishima was established on November 7, 2005, from the merger of the city of Kokubu, and the towns of Fukuyama, Hayato, Kirishima (former), Makizono, Mizobe and Yokogawa (all from Aira District).

The Uenohara site dates from the Jomon-era. Shrines include Kirishima-Jingu.

Kirishima is an active volcanic mountain range that lies on the border between Miyazaki and Kagoshima Prefectures. It is made up of mountains, highlands, volcanic lakes and hot springs and offers good hiking through beautiful mountainous surroundings. Due to a recent eruption by Mount Shinmoedake and heightened volcanic activity around Ebino Kogen, many of the hiking trails are currently closed.

The mountains of Kirishima play an important role in Japanese mythology. They are said to be the site where the god Ninigi no Mikoto, grandson of the sun goddess Amaterasu, was sent to rule over the earth and establish the lineage of Japanese Emperors. At the top of Mount Takachiho-no-mine you can see the spear sunk in the mountaintop, which Ninigi no Mikoto used to descend to earth.

Ebino Kogen and Kirishima Onsen are the two most prominent resort towns in the Kirishima area. Ebino Kogen on the Miyazaki side of the border, is a small village with a couple of hotels in a highland area surrounded by mountains and volcanic lakes. On the Kagoshima side is Kirishima Onsen, a more developed hot spring town with good baths and nice views over Kagoshima Prefecture.
