Yuzu is a Japanese popular music duo. Its members are Yujin Kitagawa (北川悠仁, born January 14 1977) and Kōji Iwasawa (岩沢厚治, born October 14 1976). Both of the band members come from Yokohama in Kanagawa Prefecture, and attended Okamura Junior High School. Yuzu started out as street musicians. At first, their band name was “Lights”, but Kitagawa disliked it, so they changed the name to “Yuzu”. At that time, Kitagawa was eating a Yuzu sherbet, so he named the band after the fruit. (Incidentally, Iwasawa was eating vanilla ice cream.
