Japanese metal (Japanese: ジャパニーズ・メタル, Hepburn: Japanīzu metaru) is heavy metal music from Japan. The country's first metal bands formed in the mid-to-late 1970s. The number of acts increased significantly in the next decade, but only a few saw their material released internationally, including Europe and North America with their pre-established metal bases. Domestic metal saw its commercial peak in Japan in the late 1980s and early 1990s, with the top acts selling millions of records. Many metal bands from the visual kei scene toured and gained recognition in the West in the 2000s. The 2010s saw a boom of all-female metal bands form and gain mainstream attention.
