Profile
JIHO (Choi Ji-ho), also known in English as Justin Choi, is a vocalist and performance leader of AMPERS&ONE. Dance has been a central part of his career since his training years.
He appeared in the competition programmes Wild Idol and Boys Planet before joining the FNC debut lineup in late 2023. His experience on those programmes provided early public performance opportunities.
JIHO initially served as the group’s leader; the position passed to KAMDEN in September 2024, while he remained central to choreography and stage preparation.
In interviews during the 2026 DEFINITION promotions, JIHO talked about exploring a different musical identity and encouraging fans to experience the song GOD to hear the group’s new direction.
