Officials prepare for a large crowd in central Seoul

South Korea is increasing security measures for the BTS comeback concert scheduled for March 21, 2026, in central Seoul. President Lee Jae Myung said on Tuesday that safety must be treated as a main priority, including preparation for any possible act of terror. This free BTS show is expected to bring up to 260,000 people to the area around Gwanghwamun Square and City Hall. According to the Ministry of the Interior and Safety, the comeback will likely become one of the largest public gatherings in central Seoul since the 2002 FIFA World Cup. In addition, the event is also getting international attention, with Netflix streaming the show for about 190 countries.

Authorities organize police, medical support, and public facilities

Officials said about 22,000 people with free tickets will attend the concert in person, but many non-ticket holders are also expected to gather near the area. To manage the event, authorities plan to deploy around 4,800 police officers and 3,400 city and related officials. Their work will focus on handling crowd control, emergency response, and anti-terror efforts.

In addition, Interior Minister Yun Ho-jung said the government is following a safety-first approach that includes structural inspections before the event, real-time joint command operations, and cleanup after the concert ends. The city will also provide multilingual guides, medical stations, and access to 894 public toilets in nearby buildings. Referring to the chances of terrorism threats, President Lee stated:

“Although the possibility is low, please prepare thoroughly for the potential of terrorism as well. I ask that you pool your capabilities to make it an event that successfully and safely highlights the Republic of Korea.”

Crowd safety remains a major concern after the 2022 tragedy

Public safety remains a sensitive issue in South Korea after the Halloween crowd crush in Seoul on October 29, 2022, killed 159 people. Since then, officials have remained alert during large gatherings and events with crowds. Police have said overnight camping cannot be fully prevented, although large tents will not be allowed. Yun said the concert should present both Korean culture and Korean safety to the world. Meanwhile, the president said the event will showcase the excellence of KPop and KCulture.

“I believe it will serve as an important opportunity to repeatedly confirm the excellence of K-pop and K-culture worldwide, as well as the high status of the Republic of Korea.”
