Before NEXZ
YU was the oldest member of the final NEXZ lineup. Before the program, he had trained with Sun Music Fukuoka. He did not enter the show as a JYP trainee, and the early evaluation exposed gaps in his basic technique rather than hiding them behind his appearance.
Nizi Project Season 2
YU finished eighth in the first Japanese camp and fifth in the final. His route was built around visible correction. The point was not that he arrived polished. He kept improving across the Korean stages until the final lineup had a place for him.
NEXZ Career
NEXZ released the Japanese and Korean versions of “Miracle” on December 18, 2023, three days after the final lineup was announced. The song had been used for the final stage, so the first release connected the survival-show ending directly to the group.
The official Korean debut came on May 20, 2024 with Ride the Vibe. The group followed it with the Japanese EP Ride the Vibe (Japanese Ver.) / Keep on Moving, the Korean mini albums NALLINA and O-RLY?, and the Japanese EP One Bite. Later releases included Beat-Boxer and the group’s continuing Korean and Japanese catalog.
Their first Japanese national tour, NEXZ LIVE TOUR 2025 “One Bite,” ran for eighteen shows in fifteen cities and drew more than 50,000 people according to Sony Music Japan. The tour placed the seven members in a full concert structure rather than a short rookie showcase.
Performance File
YU brings a lower vocal color and a taller physical line to NEXZ formations. His improvement story remains useful context, but the current performances should not be described as if he is still the contestant struggling through an early evaluation.
NEXZ does not publish a rigid list of permanent main and lead positions on its current official profile. This page follows the work visible in releases and performances instead of turning a fan-assigned position into an official fact.
Where to Start
- “Miracle”: the final-show song and first pre-debut release.
- “Ride the Vibe”: the Korean debut and the first full introduction to the lineup.
- “O-RLY?”: a louder Korean comeback that gives the members more comic character.
- “One Bite”: the Japanese title track that became the identity of their first national tour. Read the CVM Sekai React.
