Profile

YUTO is the Japanese member and main dancer of ONF’s OFF Team. He debuted with the group in 2017 and is known for agile choreography and expressive stage performance.

Previously credited as U, he began promoting as Yuto in 2025. KI Entertainment confirmed the updated name when all six members signed with the agency in March 2026. His Japanese background is distinct from the other five members’ South Korean nationality.

His dancing, group recordings and performance videos are not the same as a separately released personal music single. The independent solo-MV section is omitted until such a release is verified.

Yuto, also known by his former stage name U, is a Japanese dancer and performer in ONF. He contributes to the group’s visual choreography and six-member stage formations.
