South Korean boy band BTS celebrated its 13th debut anniversary with a two-night “ARIRANG” world-tour concert in Busan [1, 2, 3].

The event marks a significant milestone for the group, returning to a homecoming setting to thank its global fanbase, known as ARMY, 13 years after its June 13, 2013, debut [2, 5].

The concerts took place on Friday, June 12, and Saturday, June 13, 2026, at the Busan Asiad Main Stadium [1, 2, 4]. The performances served as the centerpiece for the anniversary weekend, blending the group's global tour presence with a localized celebration in South Korea [1].

Attendance figures for the event highlight the group's enduring popularity. Reports indicate that approximately 110,000 fans attended across the two nights [4]. Other data suggests this figure of about 110,000 fans specifically characterized the attendance of the second night [3].

During the festivities, a massive coordinated effort saw 55,000 people singing together during the concert [4]. This scale of engagement underscores the symbiotic relationship between the group and its supporters — a bond the group sought to honor through the Busan homecoming [5].

The "ARIRANG" series integrated the city of Busan into the tour's identity, creating a destination-based experience for fans traveling from across the globe [1]. This approach allowed the group to mark its anniversary while maintaining the momentum of its world tour schedule [1, 2].
