BTS began a two-day concert series in London tonight at the Tottenham Hotspur Stadium [1], [2].

The event marks a significant return to the United Kingdom for the group and serves as a centerpiece for their current global outreach. This return is particularly notable as it is the first time the group has performed in London in seven years [1].

The concerts are part of the "Arirang" world tour, which has been described as the largest K-pop world tour in history [1], [2]. The ambitious itinerary includes a total of 88 shows [1] spanning 34 cities [1].

Fans, known as ARMY, began gathering outside the venue early in the day. Reporter Jo Su-hyun of YTN said global fans were arriving at the stadium even though there were approximately eight hours remaining before the start of the performance [1].

The atmosphere among the crowd was described as highly excited. Jo Su-hyun said fans appeared thrilled to wait for the group's return to the city [1].

An anchor for YTN said BTS is continuing the largest world tour in the history of K-pop starting with these two days of performances in London [1]. The scale of the Arirang tour reflects the group's sustained international influence and the growing infrastructure of K-pop's global touring capabilities.

The 'Arirang' world tour is described as the largest K-pop world tour in history.

The scale of the Arirang tour, featuring 88 shows across 34 cities, signals a shift in K-pop's operational capacity. By returning to major markets like London after a seven-year hiatus, BTS is not only reclaiming their previous audience but testing the limits of the genre's ability to sustain massive, long-term global tours.
