Jin, born Kim Seok-jin on 4 December 1992 in Gwacheon, Gyeonggi Province, South Korea, is a singer-songwriter and the eldest member of the seven-piece boy band BTS. He was studying film at Konkuk University in Seoul when talent scouts from Big Hit Entertainment, now HYBE Corporation, approached him on the street, leading to a formal audition and trainee contract. Unlike several of his future bandmates, Jin had no prior background in dance or singing and has often described himself as the member who trained hardest to catch up. He debuted with BTS on 13 June 2013 and has remained the group’s oldest member, earning the nickname “Worldwide Handsome” after using the phrase, tongue-in-cheek, during an early press conference. All seven BTS members, including Jin, completed South Korea’s mandatory military service between December 2022 and June 2025, with Jin the first to enlist and the first to be discharged, a milestone widely covered by CNN.

In BTS’s early years, Jin was primarily positioned as a visual and vocal member while RM, Suga and J-Hope handled most of the group’s songwriting and rap lines. He gradually built a songwriting credit list of his own, co-writing solo tracks that appeared on BTS albums as introspective, ballad-leaning interludes rather than singles, including “Awake” from “Wings” in 2016, “Epiphany” from “Love Yourself: Answer” in 2018, and “Moon” from “Map of the Soul: 7” in 2020, all of which charted on South Korea’s Gaon Digital Chart according to the group’s own release history. Outside music, Jin became known in this period for a self-produced mukbang and cooking web series called “Eat Jin,” in which he cooked and ate meals on camera and later took audience questions live, a format that predated the wider Korean mukbang trend on Western platforms and became one of the group’s most consistently referenced pieces of fan-facing content.

Jin’s individual profile grew alongside BTS’s crossover into the US mainstream between 2018 and 2021, but his clearest solo breakthrough came after he began military service. In October 2022, days before his enlistment, he released “The Astronaut,” a single co-written with Coldplay’s Chris Martin, Guy Berryman, Jonny Buckland and Will Champion and produced by Kygo. Martin has said the song grew out of a phone call in which one of the BTS members explained he was about to leave the group for two years of mandatory service and wanted a song that said goodbye to fans. “The Astronaut” debuted at number 51 on the Billboard Hot 100, Jin’s first solo entry on the chart, as reported by Billboard. Following his June 2024 discharge, Jin released his debut solo studio album “Happy” in November 2024, which debuted at number 4 on the Billboard 200, and his second solo album “Echo” in May 2025.

“Happy,” Jin’s debut solo album, opened at number 4 on the Billboard 200 with around 77,000 equivalent album units in its first week, a result that made Jin the seventh and final BTS member to reach the chart’s top ten as a soloist, according to Soompi, making BTS the first K-pop act with a full septet of top-ten solo charting members. In mid-2025 Jin undertook his first solo fan tour, “#RUNSEOKJIN_EP.TOUR,” which included two sold-out nights at the Honda Center in Anaheim, California, on 17 and 18 July 2025. Those shows made him the first Korean solo artist to sell out consecutive nights at the venue and set its attendance record for a K-pop solo act, a run KStarTrend reported drew more than 25,000 fans across the two dates. A Forbes review of the Anaheim shows described the tour as a showcase of Jin’s individual pull as a live draw independent of BTS, coverage available via Forbes.

Jin was ranked sixth overall in Forbes Korea’s 2026 Power Celebrity list, the highest placing of any individual BTS member that year and second among all Korean solo idol artists regardless of gender, according to StarNews Korea’s coverage of the rankings, with BTS as a group taking first place overall. His public image is closely tied to a self-deprecating, comic on-camera persona built through years of livestreams and variety appearances, which sits alongside his reputation, reinforced by red-carpet appearances for luxury houses such as Gucci and Fred, as one of K-pop’s most recognised style figures. His military discharge in June 2024 was treated as a national news event in South Korea, with outlets including NBC News covering the crowds of fans and press that gathered at his base to mark the occasion.

Since completing military service, Jin has assembled one of the most active individual endorsement portfolios of any BTS member. French jeweller Fred named him its first global brand ambassador in July 2024, timed to the Paris Olympics, as reported by allkpop. Gucci followed in August 2024, naming Jin a global ambassador with creative director Sabato De Sarno citing his “warm and kind personality,” a partnership covered by Fashionista. Korean skincare brand Laneige named him its first-ever male global ambassador in September 2024 for its Cream Skin line, according to Billboard, and US athleisure label Alo Yoga signed him as its global ambassador in October 2024, an announcement that Sportskeeda reported generated $3.6 million in media impact value within 24 hours and made Jin the first BTS member to front a sportswear brand.

Jin co-owns Ossu Seiromushi, a Japanese-style steamed food restaurant near Seokchon Lake in Seoul’s Songpa District, which opened in July 2018 and is run day-to-day by his older brother, Kim Seok-jung, who serves as chief executive while Jin holds a director role and an ownership stake, according to Koreaboo’s coverage of the opening. As a member of BTS, Jin also holds a personal equity stake in HYBE Corporation, having received 68,385 shares ahead of the company’s 2020 stock market listing as a gift from HYBE chairman Bang Si-hyuk; secondary market trackers cited by Sportskeeda put his retained holding’s value at more than 10 billion won, or roughly $6.9 million, as of recent filings, a figure that varies by member depending on how much of the original allotment each has kept.

Jin has built a concentrated property portfolio in Hannam The Hill, a 600-unit luxury residential complex in Seoul’s Yongsan District favoured by business executives and celebrities. He first bought into the complex in 2019, and in June 2025 purchased a third unit there, a 243-square-metre apartment for 17.5 billion won, or around $12.7 million, paid entirely in cash, according to the Korea Times. In 2026 he sold one of his earlier Hannam The Hill units, a 235-square-metre apartment, for 12.7 billion won, or about $10 million, realising a profit of roughly 8.2 billion won, or $5.7 million, over almost seven years of ownership, as reported by ZAPZEE. Beyond real estate, his major assets include his HYBE shareholding and his stake in the Ossu Seiromushi restaurant business.
