Jinjin

Park Jin-woo (Korean: 박진우; born March 15, 1996), known professionally as Jinjin (진진), is a South Korean rapper, singer, songwriter and dancer. He is the leader of South Korean boy group Astro and former member of its sub unit Jinjin & Rocky with ex-member Rocky under the label Fantagio.[edit]

Jinjin currently holds no placement in the iFANN Global Top 1,000 or any published Top-100 scope list. While his influence as a leader and main rapper is undeniable within the K-pop sphere, the global fame engine has evaluated him without assigning a specific numeric rank at this time. This absence of a score reflects a dynamic landscape where visibility fluctuates based on recent releases and international campaigns rather than a static lack of impact. The core of his reach remains anchored by AROHA, the official fandom of ASTRO. Though AROHA serves the entire group, Jinjin has cultivated a distinct space known as "JinLab," a nickname visible on his social media that functions as a dedicated laboratory for his artistic output. Through this channel, he shares behind-the-scenes production insights and personal updates, fostering an intimate dialogue with fans who organize streaming parties and coordinate birthday tributes ranging from subway ads to digital campaigns. His bond with the fanbase is defined by deep reciprocity, particularly highlighted during moments of collective grief following the passing of Moonbin, where fans rallied around his promise to care for their fallen member's family. This shared history transforms the standard idol-fan dynamic into a narrative of mutual growth and loyalty, ensuring his solo projects and sub-unit work with ZooniZini receive immediate, passionate support.[edit]

Fans often recount the story of Jinjin's early days as one of the first five trainees introduced via the "iTeen Photo Test Cut," spending two years honing his craft before debuting with ASTRO in 2016. This narrative of perseverance is central to his identity as the group's leader. A defining moment in the group's folklore occurred after the death of member Moonbin in April 2023, when Jinjin publicly promised to look after Moonbin's family, a gesture that resonated deeply with AROHA and became a foundational story explaining the group's enduring bond. The cultural mythology surrounding him also includes the formation of the sub-unit JINJIN & ROCKY, which marked a significant shift in his career by showcasing his ability to lead a smaller unit while maintaining ASTRO's identity. More recently, the announcement in July 2025 regarding the debut of the new sub-unit ZooniZini with MJ confirmed his status as a core pillar of the group's future direction. Additionally, a unique chapter in the group's timeline emerged in June 2025 when Fantagio revealed Jinjin had been diagnosed with an autoimmune disease, granting him an exemption from mandatory military service. This event reshaped the group's activities and highlighted the health challenges faced by idols, adding a layer of contemporary lore to his legacy.[edit]
