Yuzu (ゆず?) is a Japanese pop duo. Its members are Yujin Kitagawa (北川悠仁, Kitagawa Yujin?, born January 14, 1977) and Kōji Iwasawa (岩沢厚治, Iwasawa Kōji?, 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. So the band name might have been Vanilla. Sometimes Iwasawa tells this story). The fans of Yuzu are called "Yuzukko (ゆずっ子)".
