Busan: The number of hotel reservations booked by foreign tourists in the southeastern port city of Busan rose sharply ahead of next week's concert by K-pop sensation BTS, industry sources said Wednesday.

According to Yonhap News Agency, Hanwha Hotels and Resorts reported that foreigners accounted for 42 percent of the rooms booked at its Matie Osiria hotel in the port city from June 11 to 13, marking a significant increase from just 0.2 percent during the same period last year. BTS' performances in Busan are scheduled for June 12-13.

Hanwha Hotels also noted a tenfold increase in the number of rooms booked by foreign tourists for the entire month of June compared to the previous year. Paradise Hotel Busan, another luxury accommodation in the city, reported that more than 90 percent of its rooms were booked during the concert period, with foreigners making up 70 percent of the guests.

"The (BTS) Busan performances are not just concerts but a citywide tourism event," an industry official stated. "As overseas fans visiting Busan for the concerts enjoy accommodation, shopping, and tourism, the event is expected to have a positive impact on the regional economy."
