ASTERISM is a three-piece next generation heavy metal band from Japan. The members are HAL-CA(Gt./Vo), MIYU(Ba.), and MIO (Dr.). In March 2023, they made their major debut with SME Records. ASTERISM aims for further global expansion with a new genre "MASS METAL" which means "a metal that reaches, resonates, and is loved by the masses", based on their meticulously composed music and their unique pop sensibilities. Their activities are global, with performances in the United States, France, Korea, China, Saudi Arabia, Thailand, Singapore, India, and other countries, resulting in a large number of local fans. A successful one-man tour was just held in November 2024, starting with a performance in Los Angeles.
