BTS Concert Seoul: Crowd Size, Security & Safety Measures

Seoul came alive on Saturday, March 21, 2026, as BTS delivered their highly anticipated comeback performance, ‘BTS THE COMEBACK LIVE | ARIRANG’ at Gwanghwamun Square. The free concert, marking the release of their fifth full album ‘ARIRANG’, drew a massive crowd and sparked both celebration and debate, with South Korean President Lee Jae-myung publicly endorsing the event and emphasizing the importance of safety. The performance, livestreamed globally via Netflix, represented a significant cultural moment, but attendance figures varied widely depending on the source.

The choice of Gwanghwamun Square as the venue was itself noteworthy, as it marked the first time a solo concert by a singer has been held at the iconic location. The event was planned around the theme of ‘Arirang’, aiming to share both Korea’s beautiful cultural heritage and the global appeal of K-culture. Although, the scale of the event prompted questions about resource allocation and security, leading to public discussion and even presidential commentary on the preparations.

Extensive Security Measures in Place

Recognizing the potential for large crowds, South Korean authorities implemented extensive crowd control and safety measures. President Lee Jae-myung stressed that safety and security were the top priorities, with preparations also including readiness for possible “terror” acts. A substantial security presence was deployed, with approximately 6,700 police officers and 8,200 security staff from the city and HYBE, the entertainment company that owns BigHit Music, working to manage the event. These measures included thorough preparation for traffic and crowd management, as well as emergency response protocols before and after the performance.

Discrepancies in Attendance Estimates

Although HYBE reported an estimated 104,000 attendees at the Gwanghwamun Square concert, based on ticket sales and data from the country’s three major mobile carriers, police estimates were significantly lower. The Chosun Daily reported that around 40,000 to 42,000 people were present near Gwanghwamun and its neighboring areas by 8 pm on the night of the concert, a figure considerably below the initially anticipated 260,000. The square itself accommodated 22,000 ticketed attendees, with non-ticket holders permitted to view the performance from surrounding areas, provided they remained in motion.

Presidential Endorsement and Public Reaction

President Lee Jae-myung publicly backed BTS’s performance, stating his anticipation for the event and highlighting its potential to showcase Korean culture globally. In a social media post on March 18, 2026, he wrote, “On Saturday, March 21, the proud artists of the Republic of Korea, BTS, will perform at Gwanghwamun Square. I look forward to this being a meaningful time to share our beautiful cultural heritage and charm of K-culture under the theme of ‘Arirang’.” However, this endorsement sparked online debate, with some netizens questioning whether the event warranted such high-level attention and expressing concerns about potential favoritism. Koreaboo reported on the backlash, noting criticism of the government’s involvement.

Impact on Surrounding Areas

The scale of the event necessitated temporary changes to operations in the surrounding area. The Sejong Center for the Performing Arts canceled scheduled performances, and the National Museum of Korean Contemporary History was closed to accommodate the anticipated crowds. These adjustments underscored the logistical challenges of hosting such a large-scale concert in a central urban location. Allkpop detailed these logistical changes.

As BTS continues to solidify its position as a global cultural force, the ‘ARIRANG’ comeback live performance at Gwanghwamun Square serves as a reminder of the group’s immense popularity and the complex interplay between entertainment, politics, and public perception. The event’s success, despite the varying attendance figures and public debate, highlights the enduring appeal of BTS and their ability to draw attention to Korean culture on a global stage. The focus now shifts to the continued success of the ‘ARIRANG’ album and the group’s future endeavors.
