Sony Music Entertainment (Japan) Inc. , often abbreviated as SMEJ or simply SME, and also known as Sony Music Japan for short, is a Japanese music arm for Sony. Founded in 1968 as CBS/Sony, SMEJ is directly owned by Sony Group Corporation and is operating independently from the United States-based Sony Music Entertainment due to its strength in the Japanese music industry. Its subsidiaries include the Japanese animation production enterprise, Aniplex, which was established in September 1995 as a joint-venture between Sony Music Entertainment Japan and Sony Pictures Entertainment Japan, but which in 2001 became a wholly owned subsidiary of Sony Music Entertainment Japan. It was prominent in the early to mid '90s producing and licensing music for animated series such as Roujin Z from acclaimed Japanese comic artist Katsuhiro Otomo and Capcom's Street Fighter animated series.
