ASTRO ARCHIVE · LEADER · MAIN RAPPER · PRODUCER
Jinjin
Jinjin leads ASTRO without performing leadership like a military drama. He raps, writes, produces, hosts and keeps the group’s difficult history attached to real people instead of polished company language.

Before ASTRO
Park Jin-woo studied dance at NY Dance Academy and entered Fantagio as a trainee before appearing in To Be Continued. His pre-debut background explains why the leader also became one of the group’s strongest movement teachers. He was not selected because he was the loudest person in six chairs. His value is the ability to watch, translate and steady a team full of very different public personalities.
Music, performance and work
Jinjin is ASTRO’s main rapper and a regular writer and producer. He helped make the rap line feel musical rather than stapled onto bright pop, then partnered with Rocky for the Restore unit album and “Just Breathe.” His solo and project work keeps expanding the production file. Radio, podcasting and theater also suit him because his warmth reads clearly without demanding center-stage volume.
The panda side quest
Follow Jinjin through studio credits and long-form talking content. Short clips make him look like the calm member surrounded by chaos. Longer conversations reveal the actual side quest: he remembers timelines, checks how people are feeling and can explain a production decision without turning it into résumé soup. His dog and photography content are the decompression layer.
Fandom notes and things the fact box misses
- Leadership style: low-volume, high-attention.
- Unit: Jinjin & Rocky debuted with Restore.
- Creative work: rap writing, composition and production across group and solo projects.
- Performance base: trained dancer as well as rapper.
ASTRO leadership and the work people do not see
Jinjin debuted as ASTRO’s leader and main rapper on February 23, 2016. He trained as both a rapper and dancer, which helps explain why his leadership often looks practical rather than ceremonial. He can read blocking, timing and energy from inside a performance instead of treating leadership as a microphone handed to him after the stage is over.
His legal name is Park Jin-woo. He was born on March 15, 1996 in Ilsan, South Korea, and trained at Fantagio before ASTRO’s debut. Within the group’s catalog he has written a large share of his own rap material and accumulated lyric, composition and production credits. Those credits matter because Jinjin’s identity is not limited to delivering a prepared rap break. He has participated in building the musical structure around it.
ASTRO’s history changed sharply after Rocky left the group in 2023 and Moonbin died that April. A responsible current profile does not freeze the group at six members or turn grief into promotional decoration. Jinjin remains an active ASTRO member under Fantagio, and his solo work exists alongside the group’s altered reality. His calm public presence should not be mistaken for a lack of feeling or ambition.
Jinjin & Rocky, Wave in my heart and JIN LAB
Jinjin and Rocky debuted as the ASTRO unit Jinjin & Rocky in January 2022 with the mini album Restore. The project let both members push further into writing, production and performance direction. The unit ended when Rocky left Fantagio and ASTRO in February 2023, so it belongs in the history as a completed chapter rather than a currently active duo.
Jinjin’s individual recording path became clearer in October 2023 with “Wave in my heart,” featuring YUNHWAY and released with KozyPop. He participated as producer, lyricist and composer on the deep-house track. That release is the cleanest starting point for his active solo-artist timeline, which is why CVM Sekai dates his solo status from 2023 rather than from the earlier unit era.
In March 2024 he launched the JIN LAB project with “Good Enough.” The release was presented through ASTRO’s official channel and credited Jinjin in the writing, composition and arrangement process. JIN LAB continued as a place for self-directed songs and collaborations, including “for me” with MRCH. In 2025 he expanded the project into his first solo concert, JIN LAB Vol. 1: Find Your Groove, turning the studio label into a live catalog.
The through-line is control over process. Jinjin is not chasing a solo image that rejects ASTRO. He is using individual releases to make the producer and songwriter work more visible, while group leadership remains a separate responsibility.
ZOONIZINI, DICE and the 2025 unit chapter
Jinjin opened another ASTRO unit chapter with MJ in 2025. Fantagio announced the duo ZOONIZINI in July, and the pair debuted on August 13 with the mini album DICE and its lead single “Some Things Never Change.” The unit name combines the members’ names, while the project pairs MJ’s main-vocal color with Jinjin’s rap, writing and production instincts.
DICE belongs on Jinjin’s member profile as unit work, not as a new independent group profile detached from ASTRO. ZOONIZINI is an ASTRO subunit. Its releases should connect to Jinjin, MJ and the ASTRO archive while preserving the distinction between a unit activity and the main group’s catalog.
The project also followed Jinjin’s first solo concert, JIN LAB Vol. 1: Find Your Groove, held in Seoul in February 2025. That concert gave his self-produced JIN LAB songs a live structure and showed how much material had accumulated beyond a single digital release. Later 2025 JIN LAB entries extended the catalog rather than replacing the unit work.
2026 activity and official status
Jinjin remained a current ASTRO member and Fantagio artist in 2026. Fantagio’s artist directory continued listing both ASTRO and Jinjin, while his individual Weverse community opened as a dedicated home for notices, media and live broadcasts. The platform also launched JINJIN Weverse DM and maintained his official fan-club activity.
Official 2026 activity included the “2026 HAPPY JINJIN DAY” campaign and a birthday live in March. These are useful status checkpoints because they show an actively managed artist account rather than an archived profile. They do not mean he left ASTRO: the individual community supports solo communication while his group membership remains current.
ASTRO’s post-2023 history requires careful wording. Rocky is a former member, Moonbin’s death is part of the group’s history, and the surviving members have emphasized individual and unit work. Jinjin’s leadership therefore operates in a different structure from the six-member debut era, but no official notice has removed him from ASTRO.
Writing, production and collaboration map
Jinjin’s creative credits cross three lanes. ASTRO songs document his group rap writing and production participation. Restore captures the completed Jinjin and Rocky unit chapter. JIN LAB and ZOONIZINI make his individual production choices and current unit work easier to hear. Those lanes overlap, but they should not be collapsed into one discography entry.
His production approach often favors rhythm that leaves room for conversational phrasing. He can move from an idol-rap function into melodic delivery or spoken texture without making the song stop for a separate rap showcase. That flexibility is one reason his catalog reads differently when the credits are examined alongside the performance footage.
August 2026 checkpoint: current ASTRO member and leader, active Fantagio artist, JIN LAB solo creator, and member of the ASTRO unit ZOONIZINI. Group tenure remains 2016–present.
