Uverworld (ウーバーワールド, Ūbāwārudo) is an influential rock band known for their mixture of musical genres such as hard rock, electronic, and post-punk.[citation needed] Uverchan, the band's mascot, is a fictional bear-bat like character, which appears on several of their covers.

The five-member band known as Uverworld first formed in 2003, and were known as Sound Goku Road or, more popularly, "Sangoku Road." The band originally consisted of seven members, and released Prime'03, a demo CD which ended up selling 3,000 copies. Unfortunately, one of the band members, the saxophonist Seika, left the group (the other was Hiko, who left after he married). After his departure, Ace Trigger renamed himself Takuya and the band renamed itself to Uverworld.

According to an interview with the band there was another vocalist who left, however this vocalist hasn't yet been identified. Though it appears that that person may have left some time before Seika did, as Seika is the only one of the two credited on the demo CD and pictured with very early live photos of the band pre-Uverworld.

June 11, 2008 saw the release of the single Gekidou / Just break the limit!. Gekidou was used as the fourth opening theme of the anime series, D.Gray-man, while the song Just break the limit! was used as a support song for Pocari Sweat's CM. Two more singles were released in 2008, Koishikute (恋いしくて) and Hakanaku mo Towa no Kanashi (儚クモ永久のカナシ). Hakanaku mo Towa no Kanashi was used as the opening for the second season of Mobile Suit Gundam 00 anime. The single became the bands first number 1 single on Oricon with approximately 181,784 copies sold. The single has since gone on to become the highest selling single from the band.

On February 18, 2009 the band released their 4th album titled Awakeve. The album sold over 115,000 copies on its first week and ranked #2 on the Oricon album chart. The band is also releasing a new DVD Uverworld Premium Live at Nippon Budokan on 29th of April.

The band is releasing a new single on August 5, 2009 titled as Go-On. The single's title track will be featured on the Japanese broadcast of House.
