Ketsumeishi is a popular Japanese hip-hop group featuring DJ Kohono and vocalist Ryo, Ryoji and Daizo. Ketsumeishi's songs are characterized by their heartwarming lyrics. In fact, the lyrics to their song "Todmodachi (Friend)" have once been introduced as "the lyrics that touch the hearts of youths" in a Japanese textbook for high school students. In contrast to the heartwarming lyrics, Ketsumeishi's live performances are a little extreme. They are known to enjoy a mug of beer on stage and it is one of the surprises fans can experience during Ketsumeishi's concerts.
