First Love was first sung by Utada Hikaru (宇多田 ヒカル) in 1999. I know this song when I first watched a Japanese drama called "Majo no joken" (魔女的条件). Utada Hikaru is one of the best Japanese singer of that time. Although years passed, she is still very popular in Japan. Her "First Love" song has also been sung into English version by Jessa Zaragosa.
