South Korean girl group known for empowerment anthems and explosive choreography. JYP Entertainment’s first girl group since TWICE (2015), ITZY debuted with record-breaking success.

Explosive Debut

ITZY debuted on February 12, 2019, with “DALLA DALLA” (다라다라) — a self-confidence anthem with the message “I’m different from you, and that’s okay.” The music video broke records for fastest K-pop debut MV to reach 100 million views (76 days).

The five-member group (Yeji, Lia, Ryujin, Chaeryeong, Yuna) was formed through survival shows and casting, with leader Yeji and Ryujin gaining pre-debut fame from appearances on MIXNINE and The Fan.

Musical Identity

ITZY’s signature sound combined teen crush pop with self-empowerment messages. Follow-up hits “ICY” (2019), “WANNABE” (2020), and “LOCO” (2021) reinforced themes of self-love and individuality.

“WANNABE” (2020) became their breakthrough international hit, with the lyric “I wanna be me, me, me” resonating globally during pandemic lockdowns. The shoulder dance went viral on TikTok.

Commercial Success

  • First K-pop girl group to chart on Billboard 200 with debut album
  • Rookie of the Year awards at major Korean ceremonies (2019)
  • Over 5 million albums sold by 2023
  • Multiple world tours across Asia, North America, Europe

ITZY filled the “girl crush” concept space in 4th generation K-pop, contrasting with the softer concepts of groups like TWICE. Their choreography (led by main dancer Yeji) became known for difficulty and synchronization.
