President Lee Jae Myung has urged authorities to step up safety preparations ahead of a major comeback concert by BTS in Seoul, warning of the need to be fully prepared for potential security threats, including terrorism.

Speaking during a cabinet meeting at the Government Complex in Sejong on Monday, Lee described the upcoming performance at Gwanghwamun as a globally watched event and a key moment for the country’s cultural image, while stressing that public safety must remain the top priority.

Referring to the concert, Lee said: "The BTS concert at Gwanghwamun, which the world is watching, is now only a few days away." He added: "I see this as an important opportunity to once again showcase to the world the excellence of K-pop and K-culture, and the high standing of the Republic of Korea (South Korea)."

However, he emphasised the risks involved, stating: "The issue is safety," and calling on multiple agencies to coordinate closely. "The Ministry of the Interior and Safety, the police, the fire authorities, and other relevant ministries and agencies must remain especially alert and prepare thoroughly for every possible situation."

Highlighting security concerns, Lee said: "Please ensure full preparedness." He further urged officials: "I ask that you pool your capabilities so this can be a successful and safe event that shines a positive light on South Korea."

Massive crowds expected in Seoul

The concert, titled ‘BTS THE COMEBACK LIVE: ARIRANG’, is scheduled for 21 March at Gwanghwamun Square in Seoul, marking the release of the group’s fifth full-length album ‘Arirang’.

Authorities estimate that up to 260,000 people could gather in and around the venue, including approximately 22,000 ticket holders. The event will be a standing-only concert, with large LED screens installed for wider viewing, and will also be streamed live on Netflix.

Tightened security and crowd control measures

In response to the anticipated turnout, police are preparing an extensive security operation. Around 4,800 officers are expected to be deployed, including special forces units, while additional plainclothes personnel will monitor for sudden threats such as knife attacks.

Event organiser Hybe is also set to deploy more than 4,000 staff dedicated to crowd management.

Authorities are installing fencing and controlled access zones around the venue, alongside reinforced safety structures. Special attention has been given to subway ventilation shafts, with barriers placed to prevent spectators from climbing onto them for a better view.

Lessons from past disasters

Officials said the precautions are informed by past incidents, including the Pangyo Techno Valley ventilation shaft collapse, where a structure gave way under the weight of spectators, killing 16 people and injuring 11.

The government is aiming to avoid similar risks by strengthening infrastructure checks and limiting unsafe crowd behaviour.

Coordinated national response

The central government and the Seoul metropolitan authorities plan to operate a joint response system involving police, fire services and other agencies. Measures will include traffic control, safety inspections of nearby facilities and continuous monitoring throughout the event.

Lee also pointed to recent safety concerns, including a fire at accommodation near Myeong-dong, and called for inspections of lodging facilities used by tourists attending the concert.

As the countdown to the high-profile event continues, officials say the focus remains on ensuring that the concert proceeds without incident while projecting South Korea’s cultural influence on the global stage.
