Do As Infinity is a Japanese pop and rock band that formed in 1999 with three members: vocalist Tomiko Van, guitarist Ryo Owatari, and guitarist and composer Dai Nagao. The band’s name is sometimes abbreviated as D.A.I., alluding to the fact that Do As Infinity was named after Dai Nagao. Do As Infinity disbanded on September 29, 2005. The members continued work in the music industry, with Van pursuing a solo career, Owatari working with his band Missile Innovation formed in 2004, and Nagao continuing to work with other artists at Avex Trax. The band reformed on September 29, 2008, but Nagao did not return.

One of the 1st few bands from Japan I listened to when I was in secondary school. Back then, JPOP was so popular but now it has died down so badly because of the Hallyu wave. This song was released in 2001 and it is used as the theme song for the drama Yome wa Mitsuboshi.
