Following of the success of the singles, Onitsuka's debut studio album Insomnia was released in March 2001 to commercial success, peaking at number one on the Oricon Weekly Albums chart and having sold over 1,300,000 copies. The album later earned a Rock Album of the Year at the Japan Gold Disc Award. In support of the album, Onitsuka embarked on her first concert tour "Chihiro Onitsuka Live Tour 2001" in April 2001.
