Early Life and Background
Juhoon was born Kim Ju-hoon on January 3, 2008, in Seoul, South Korea. Before ever becoming a K-pop trainee, he was already a working child model, appearing in campaigns for various fashion brands and making appearances in music videos for VIXX’s “Scientist,” Zion.T’s “Hello Tutorial” (alongside Ella Gross, who later debuted in Meovv), and MeloMance’s “Tale,” “You & I,” and “Festival.”
He was also active in soccer as a child, giving him an athletic foundation alongside his early performing experience.
Juhoon joined BigHit Music as a trainee and, as part of his preparation, worked to improve his English fluency during training — a detail that’s since proven useful given CORTIS’s rapidly growing international profile.
Career Highlights
Debut and CORTIS’s Formation Juhoon officially debuted as a member of CORTIS, BigHit Music’s third group after BTS and Tomorrow X Together, on August 18, 2025, with the digital single “What You Want,” following the pre-release single “GO!” released a week earlier.
As vocalist, his expressive performance style and musical involvement quickly became a defining part of the group’s sound.
A Hands-On Songwriter Juhoon co-wrote and composed several tracks on CORTIS’s debut EP, Color Outside the Lines, released September 8, 2025, including “GO!,” “What You Want,” “FaSHioN,” and “JoyRide,” and he also helped shape the choreography for “GO!”
That creative involvement continued into the group’s second EP, GreenGreen, released May 4, 2026, where he contributed to “TNT,” “REDRED,” “ACAI,” “YOUNGCREATORCREW,” and “Wassup” — making him one of the more consistently musically active members of the group.
A Group Built on Creation CORTIS operates without fixed member positions, with all five members — including Juhoon — contributing directly to songwriting, music production, videography, and choreography across the group’s discography, reflecting the group’s identity as genuine “young creators” rather than performers alone.
Rapid Global Rise CORTIS’s rise since debut has been remarkably swift. The group’s GreenGreen EP charted across numerous international markets, including a peak of Number 2 on Japan’s Oricon Albums chart and top-10 placements in Belgium, France, and Austria.
In 2026, CORTIS also headlined NBA All-Star Game weekend, a historic first for a K-pop group, and embarked on a sold-out world tour.
Personality and Public Image
Juhoon has become known among fans as the steady, low-key member who keeps the group’s day-to-day mood grounded — a calm presence that fellow member James specifically pointed to when explaining why he’d choose Juhoon to accompany him to a remote island, reasoning that Juhoon’s temperament would make even isolation feel like a relaxing vacation rather than a stressful ordeal.
Juhoon has said he hopes people find CORTIS to be genuinely fresh, reflecting the group’s effort to bring something new to their songs, videos, and choreography.
His own first impressions of fellow members Seonghyeon and Keonho were that both were exceptionally kind to him, while his first impression of leader Martin was that he was simply “cool” thanks to his singing and dancing skills.
