Kagoshima 2nd district (鹿児島[県第]2区, Kagoshima[-ken dai-]ni-ku) is a single-member electoral district of the House of Representatives, the lower house of the National Diet of Japan. Located in Southern Kagoshima Prefecture it covers parts of the capital Kagoshima City (former municipalities Taniyama City and Kiire Town), Ibusuki City and former Ei Town (now part of Minami-Kyūshū) in the main island part of Kagoshima, and Amami City and Ōshima County on the Amami islands. As of 2013, 279,541 eligible voters were registered in the district, giving it above-average vote weight.
From 2000 to 2014, the district had been represented by the Tokuda family who runs the Tokushūkai hospital group. A political funds scandal in 2013 over donations from Tokushūkai led to the resignations of Tokyo governor Naoki Inose and Takeshi Tokuda.
