Mount Kongō (金剛山, Kongō-san) is a 1,125-metre-high (3,691 ft) mountain in the Kawachi region of Osaka Prefecture, Kansai, Japan. It is near Mount Yamato Katsuragi. The mountain has lent its name to a series of naval ships and ship classes: the Imperial Japanese Navy's 1877 ironclad Kongō; the 1912 battleship Kongō, the name ship of her class; and the Japan Maritime Self-Defense Force's current destroyer Kongō (DDG-173), also the name ship of her class.
