Rookie K-Pop duo FLARE U has successfully captured the hearts of global fans even before their official debut. The highly anticipated group delivered an unforgettable pre-debut performance at KCON JAPAN 2026. Taking over the Makuhari Messe from May 8 to 10, they proved they are a force to be reckoned with.
Dominating the Stages at KCON JAPAN 2026
FLARE U brought immense energy to both the Dance Stage and the X Stage during the massive international festival. Fans were thrilled to see the duo commanding the spotlight with their fierce choreography and undeniable stage presence. Their confidence made it hard to believe they are still technically a pre-debut act.

Exclusive ‘YOUTH ERROR’ Track Reveal
During the event, attendees were treated to an exclusive preview of FLARE U’s upcoming first mini album, YOUTH ERROR. The highly anticipated debut project is officially scheduled to drop on May 13. The duo gifted the KCON audience with performances of three previously unreleased tracks:

- The hard-hitting title song, “WAY 2 U”
- An energetic B-side titled “Hyper”
- The incredibly catchy track “WOO-HOO”
Special Collabs and Boys II Planet Roots
Adding to the excitement, FLARE U teamed up with fellow rookie boy group MODYSSEY for a special collaboration cover stage. The seamless teamwork between the two emerging groups became an instant highlight of the festival. They also charmed the press and fans alike during their engaging red carpet interview.

If FLARE U looks familiar, it is because members Choi Lip Woo and Kang Woo Jin are already beloved by many. Both idols previously showcased their stellar talents as popular contestants on Mnet’s hit survival show, Boys II Planet. Their long journey from trainees to a powerful K-Pop duo adds deep meaning to their debut.

Anticipation for the Official Debut
