BTS begins comeback tour to reclaim status as one of the world’s biggest pop acts after completing Korea’s mandatory military service

After a four-year break, K-pop supergroup BTS returned Saturday with a massive, free comeback concert in Seoul, where thousands of police locked down a central boulevard for the Netflix-exclusive spectacle that drew tens of thousands of fans.

“Annyeonghaseyo! We’re back,” RM, the band’s leader, told the crowd, using the Korean word for “hello,” as they opened with “Body to Body,” setting off delirious screams from fans waving purple-and-red light sticks and thrusting smartphones into the air.

All seven members of the band — RM, Jin, Suga, J-Hope, Jimin, V and Jung Kook — recently completed South Korea’s mandatory military service, and hope to reclaim their status as one of the world’s biggest pop acts.

The performance at Gwanghwamun Square launches a global tour spanning dozens of shows across the United States, Europe and Asia, which analysts say could generate hundreds of millions of dollars in revenue per quarter.

The hourlong concert came after the group on Friday released its fifth album, “ARIRANG,” which sold nearly 4 million copies in its first day, said the band’s management company, HYBE. The company also said RM had injured his ankle during a rehearsal, but he still performed with modified choreography.

The BTS concert, which began at 8 p.m., drew several tens of thousands to the Gwanghwamun area, including 22,000 fans who secured free seats in the designated viewing zone and others who watched on screens nearby. The show was streamed live on Netflix.

“It will be amazing because it’s been so long that BTS (was) not with us,” Dallila Di Tullio, a 32-year-old fan from Italy, said before the concert, calling it a once-in-a-century event.

BTS debuted in 2013 and has a legion of global supporters who call themselves the “Army.” It became the first K-pop act to top Billboard’s Hot 100 chart in 2020 with their first all-English song “Dynamite.”

Jung Dukhyun, a pop culture commentator, said that the impact of BTS’ return as a full-group would be tremendous at a time when global fandom for K-pop has grown much stronger, as shown by the success of Netflix’s animated sensation “KPop Demon Hunters.”

Stringent crowd controls

The dark streets blazed with light as waves of fans sang and cheered from cordoned sections, a jubilant scene that unfolded under an unusually heavy police presence managing the crowds.

“I still vividly remember how, at our last Busan concert a few years ago, we asked you to wait for us. Thank you so much for coming here like this,” Jin said.

The group performed songs from their new album, including “SWIM,” alongside hits like “Dynamite” and “Butter.” Some members appeared to tear up while thanking fans who braved the chilly night, before holding hands and bowing to the crowd to close the show.

Police and city officials closed nearby streets and roads, halted the area’s subway and bus services, and sealed off dozens of surrounding buildings, in what amounted to a full-day shutdown of the district.

Thousands of police officers maintained a tight perimeter around the performance venue, channeling the crowds with a maze of fences and buses. Concertgoers began queuing by midday to secure spots along nearby roads, passing through security checks and metal detectors at designated entry points. The restrictions forced nearby shops to close and police to use their buses to shuttle wedding guests to a nearby venue.

“I was hoping to (see) if we can go through some holes or be around. Apparently we cannot because they will be asking people to move,” said Bernice Sanchez, a 52-year-old fan from Switzerland, as she looked for a place to wait.

While South Korean officials have taken crowd safety more seriously since a 2022 Halloween surge that killed nearly 160 people, critics say the controls went too far and undermined the symbolism of performing in Gwanghwamun, seen as Seoul’s spiritual heart and most prominent gathering space.

Hundreds of thousands have gathered in Gwanghwamun in recent years to mourn, protest and celebrate as the country weathered tragedy and political upheaval. The BTS concert came about a year after waves of demonstrators filled the area, calling for the ouster of then-President Yoon Suk Yeol over his brief imposition of martial law in December 2024. Those monthslong rallies were marked by a festive atmosphere and a striking blend of politics and pop culture, with protesters singing and waving colorful K-pop light sticks, and ended without major safety accidents.

Drawing on culture and heritage

The new BTS album, “ARIRANG,” takes its name from a centuries-old folk song, regarded as an unofficial anthem in both Koreas, whose themes of separation, longing and quiet resilience have echoed across generations.

Gwanghwamun and nearby Gyeongbok Palace provided a sweeping historic backdrop to Saturday’s show, which was highlighted by lighting effects that bathed the palace gate and walls in purple, red and blue.

Suga told the crowd that the album’s title and the decision to perform in Gwanghwamun reflected the group’s focus on identity. RM said the band focused on making music that felt true to themselves as they reconvened to work on the new album.

“We wanted to show who we are and how we can come together,” he told the crowd.

South Korean officials, including current President Lee Jae Myung, expressed hope that the event would promote the country’s culture and soft power.

Group’s comeback coincides with K-pop’s global rise

The group’s comeback follows a nearly four-year hiatus driven by South Korea’s mandatory military service, which requires most able-bodied men to serve 18 to 21 months under a conscription system aimed at deterring aggression from North Korea. BTS members began serving in 2022, with Suga the last to complete his service in June 2025.

Some analysts say the group’s “ARIRANG” world tour could become the biggest K-pop tour ever by scale and revenue, with 82 shows planned globally in stadiums of around 50,000 seats. Ha Jae-keun, a cultural critic, said BTS was likely to have a “second heyday,” as they maintained a highly powerful fandom and would benefit from the broader international ascent of K-pop.

“We will do our best to give everything we got,” J-Hope said
