Throughout Southern's career, Kuwata has featured extremely erotic expressions in many of his self-written songs and the band's sales promotions. "I Love You wa Hitorigoto", Kuwata composition released as Hara's first solo single in 1981, was banned due to suggestive lyrics including the term "motel". The cover of the band's 1983 single "Body Special II" featured the breast of a topless woman. Such explicit expression from Kuwata and his band's music has continued to date.
