BREAKERZ is a Japanese rock band formed in April 2007. The group is fronted by vocalist DAIGO, also known as DAIGO☆STARDUST, alongside guitarists SHINPEI and AKIHIDE, who also provide chorus and synthesizer work. The band does not have a permanent bassist or drummer, relying on support musicians for both studio recordings and live performances. They are signed to the ZAIN RECORDS label and made their major debut on July 25, 2007, with the release of their self-titled album BREAKERZ.

The band has a significant and long-standing connection to anime, particularly the long-running series Detective Conan (also known as Case Closed). One notable contribution is the song Yume Monogatari, which served as the fifty-fourth ending theme for the anime. This song was used for episodes 865 through 875, which aired in 2017. Beyond Yume Monogatari, BREAKERZ has a deep discography of theme songs for the series. Their other ending themes include Hikari (ending 34), Tsukiyo no Itazura no Mahō (ending 38), Overwrite (ending 42), and SWEET MOONLIGHT (ending 65). The group has also performed multiple opening themes for Detective Conan, such as Everlasting Luv (opening 26), Miss Mystery (opening 33), WE GO (opening 40), and Ikusen no Meikyuu de Ikusen no Nazo o Toite (opening 44). In addition to full band contributions, members have provided solo songs for the series, including Ima Aitakute... by DAIGO as ending 46 and RAIN MAN by AKIHIDE as ending 47.

Their musical identity is rooted in rock and J-rock genres, and their work has achieved commercial success on Japanese charts, including a single that reached number two on the Oricon charts. Their connection to Detective Conan is a core part of their career, but their anime contributions also extend to other series, including performing theme songs for DamexPrince Anime Caravan, Love Stage!!, and Yōkai Ningen Bela. The band remains active, having released an album titled Bintage in July 2024.
