NOWZ · MEMBER PROFILE

Jinhyuk

The rapper and dancer whose writing credit makes the youth anxiety part of the members’ actual work, not motivational copy pasted onto five handsome faces.

Official pre-debut introduction

CUBE introduced Jinhyuk through a member debut trailer on March 10, 2024 and a “Write about me NOW!” video the following day. Those official clips are the cleanest starting point for his public identity because they predate the group’s debut and preserve the company’s original framing. They also establish that the performer now filed under NOWZ is the same person introduced under NOWADAYS.

The rebrand changed the group name, not the people or their previous credits. Searches for NOWADAYS Jinhyuk, NOWZ Jinhyuk, Jang Jinhyuk, and Jang Jin-hyuk should all resolve to this single profile.

Debut and the NOWADAYS catalog

Jinhyuk debuted on April 2, 2024 with the single album NOWADAYS. He participated in lyrics for “OoWee,” documenting creative work from the first release rather than adding songwriting only after the group had established itself. Later material including “TICKET,” “Let’s Get It,” and “Rainy Day” continued to build the rapper-songwriter lane while the five-member team learned how to distinguish itself inside CUBE’s catalog.

His pre-debut feature on Hui’s “Cold Killer” is useful context because it placed his voice in an official release before the group debut. It should be recorded as an individual feature, not mistaken for a full solo career.

The NOWZ rebrand and IGNITION

CUBE changed NOWADAYS to NOWZ in June 2025 and followed the rebrand with IGNITION. “Fly to the Youth,” featuring i-dle’s YUQI, made the reset meaningful by connecting an accessible youth anthem to member participation in its writing and composition. Jinhyuk’s credit helped turn the song’s uncertainty into language shaped by the performers rather than generic motivational copy.

“Problem Child,” “HomeRUN,” and “EVERGLOW” expanded the group’s performance and songwriting record. For Jinhyuk, the era emphasized how rap phrasing and movement can share the same pulse. Watch whether his weight changes occur before or after consonant accents; the choreography often makes his delivery easier to read.

Japan debut and 2026 development

NOWZ’s official Japanese profile and Warner Music Japan materials carry the same five-member lineup into the group’s Japan activities. A 2026 Japanese debut project and concert milestones extended the rebrand beyond Korea. Jinhyuk and Siyun also performed a unit cover of Mark’s “Fraktsiya,” giving fans a useful comparison point for their individual rap textures outside the group’s own title tracks.

In June 2026, Jinhyuk released a video for the unreleased self-composed song “ROSE” through NOWZ’s official YouTube channel. SBS reporting identified it as part of the members’ songwriting relay. Because the track was presented as unreleased official-channel content rather than a commercially promoted solo debut, this profile remains Member-only unless CUBE formally launches a solo catalog.

Rap, writing, and performance craft

Jinhyuk’s lower register gives NOWZ rhythmic weight, but the useful question is how he changes color. “OoWee” needs an immediately readable rookie-group hook; “Problem Child” invites more abrasion; “Fly to the Youth” asks him to sound involved in the anxiety rather than detached from it. Writing participation gives that last interpretation additional credibility.

Full-stage footage shows the second half of the job. A rapper in a choreography-heavy group must keep the verse legible while moving into and out of formations. Look for how he preserves breath before dense syllables and how he uses the final count of a phrase to hand focus to another member.

Member and Artist classification

This is Jinhyuk’s canonical person profile. His group writing, pre-debut feature, and official unreleased song belong here, but they do not yet establish a formally promoted solo career. He remains in the Member directory only. If CUBE releases an official solo catalog later, the Artist tag can be added to this same page without creating a duplicate profile.

Before the public file began

Jinhyuk entered the public NOWADAYS lineup for the 2024 debut, but his useful profile grows after it. The rebrand gave him heavier material and more room to help build the songs. By “Fly to the Youth,” he was sharing both lyric and composition credit with YUQI, Wooseok, Siixk Jun and Siyun.

What Jinhyuk brings to NOWZ

Jinhyuk gives NOWZ low-end pressure without treating every rap as the same aggressive color. “Problem Child” lets him perform rebellion. “Fly to the Youth” lets him help author uncertainty. That difference is why credits belong in the profile instead of a tiny line nobody reaches below the album art.

NOWADAYS did not become a different human

Jinhyuk debuted with the same five-member lineup under the name NOWADAYS. Cube changed the group name to NOWZ on June 2, 2025. The pre-rebrand releases, credits and relationships remain part of this profile. One person gets one page; roles and eras are trails, not duplicate humans.

The panda side quest

Read the “Fly to the Youth” credits, watch both Korean and Chinese official videos, then move into “Problem Child,” “HomeRUN” and “Achilles.” Listen for where his rhythm changes before watching the choreography again.

Fandom notes and things the fact box misses

• Composer file: “Fly to the Youth” is the receipt that he participates beyond assigned rap lines.
• Three words: passion, grit and authenticity were his own shorthand for NOWZ at the two-year mark.
• Performance pressure: he works best when choreography treats rap as movement instead of a stationary close-up.
• DAY_AND: the current NOWZ fandom name; the original D-DAY name was changed because it was already in use.
• Rebrand rule: old NOWADAYS clips still belong to the same member and should not be filed as a former group.
