Kawaii metal is a musical genre that blends elements of heavy metal and J-pop that was pioneered in Japan in the early 2010s. The genre combines both Eastern and Western influences that appeal to both cultures. A typical kawaii metal composition combines the instrumentation found in various types of heavy metal music with J-pop melodies and a Japanese idol aesthetic. Kawaii metal's lyrical topics often contain kawaii themes.

Kawaii (Japanese: かわいい or 可愛い, IPA: [kawaiꜜi]; 'lovely', 'loveable', 'cute', or 'adorable') is the culture of cuteness in Japan. It can refer to items, humans, and non-humans that are charming, vulnerable, shy, and childlike. Examples include cute handwriting; certain genres of manga and anime; and characters such as Hello Kitty, as well as Pikachu from Pokémon.
