PassCode is a Japanese all-female group formed in Osaka in February 2013 and best known for its kawaii metal sound, which blends idol pop with metalcore, EDM, and electronic production. The group’s music is built on sharp arrangements, heavy guitar work, digital textures, and forceful vocals, moving between clean, catchy passages and harder-edged sections to create a style that is aggressive, melodic, and easy to recognise for listeners searching for Japanese metal-inflected idol acts.
Over time, PassCode has released singles, albums, and other material that show a steady evolution in both production and performance, balancing polished hooks with a tougher live-ready edge. That combination has made the group a familiar name in Japan’s genre-crossing vocal group scene and a frequent discovery point for fans of alternative Japanese music and anime-adjacent artists. Interest in members such as Reika Kamisaki has also helped drive anime-related searches, and in 2026 the group drew further attention with the opening song for ROLL OVER AND DIE and its associated music video.
