Happy Birthday Johnny Day! Look back at the NCT member’s career

Johnny Suh turns another year older this week, and the NCT 127 member born John Suh in Chicago continues to anchor the group with the same easy warmth that first caught fans’ attention during his trainee years. His path from Midwest auditions to global stages still reads like a long, deliberate climb, one that started in 2007 and finally hit the spotlight in 2016.

Chi-town choice

Johnny became the first member to join SM Entertainment through an American audition held in Chicago in 2007. He received official casting the following year. In December 2013 he was introduced as part of the pre-debut training team SMROOKIES. Despite clearing the initial audition, the company allowed him to commute between Seoul and Chicago to finish high school, an unusual arrangement at the time. That flexibility stretched his trainee period to roughly nine years before his official debut with NCT 127 in 2016.

In 2014 he appeared alongside future NCT members on the variety program Exo 90:2014, performing 90s tracks. He joined the unit ahead of the 2017 extended play Limitless. Earlier credits include a feature in J-Min’s “Ready For Your Love” music video, a DJ cameo in “Heartbeat” with Amber, Luna, Yoon Do-hyun, Reddy, and G2, and the “Nightmare” clip with the same lineup.

NCT – K-Pop secret weapon

SM Entertainment unveiled NCT in 2016 as a multi-unit project designed to expand across different countries. Founder Lee Soo-man described the concept as “Neo Culture Technology,” with teams that would debut based in various global locations. The original announcement gave rise to NCT 127, NCT Dream, and WayV, and the structure has since grown to seven fixed subunits including NCT Wish and the recently formed NCT JNJM.

Mark’s departure in April 2026 left NCT 127 with seven members, yet the group’s international footprint has only widened. The 2025 Neo City – The Momentum tour brought arena dates across North America, and NCT 127 is scheduled to headline KCON LA in 2026, extending the U.S. presence that first drew notice with the 2019 Microsoft Theater show and James Corden appearance.

Fashion and Media Ventures

Johnny’s post-debut profile now stretches well beyond music. He made multiple appearances at Paris Fashion Week for Acne Studios in 2024 and 2025, including a notable shirtless coat look on the runway. Media coverage also tracked his Met Gala and New York Fashion Week attendance. In 2025 he added regular variety-show credits, listed on drama databases as ongoing guest and panel roles that keep him visible between group schedules.

NCT 10th Anniversary Milestones

2026 marks NCT’s tenth year since debut, and the label launched the NCT 2026 project with a full-group album, world tours, and pop-up exhibitions tracing the group’s growth. Member-specific anniversary posts have circulated for Johnny, highlighting both his Chicago-to-Seoul journey and his current place in the expanded lineup.

Evolving NCT Structure and Lineup Changes

The original three-subunit model has shifted considerably. New fixed units such as NCT JNJM, featuring Jeno and Jaemin, debuted with the February 2026 EP Both Sides. With Mark’s exit, NCT 127 stabilized at seven members while the overall roster reached seven total subunits. These adjustments reflect SM’s decision to close the unlimited-expansion phase and focus on defined teams.

Recent Touring and Global Performances

After the 2019 U.S. run, NCT 127 returned with the 2025 Neo City – The Momentum tour, booking multiple North American arenas. The itinerary kept the group in front of larger crowds and reaffirmed the international strategy Lee Soo-man outlined a decade earlier. The upcoming KCON LA 2026 headliner slot adds another major U.S. milestone to the calendar.

Price of fame

Global recognition has brought longer tours and tighter schedules, yet Johnny has repeatedly credited the same internal support system for keeping the members steady. “Teamwork,” he explained. “We’re always traveling with the same people, it’s important how we can sometimes lean on one another, [since] we eat together, we’re all in the same house together. And it kind of shows in our performances as well.”

The group continues to prepare new music amid the 2026 anniversary slate. “When it will come out, we can’t really say, it’s a little bit of a secret, but we're getting ready,” Johnny said. “So [fans] can always have their hearts a little ready.” Those remarks, first shared during an earlier cycle, still capture the ongoing rhythm of NCT 127’s work as the subunit heads into its next chapter.
