The K-pop girl group TWICE is on a world tour this year, and after 1 million ticket applications, 15 concerts are sold out.

According to Billboard Japan, the group immediately sold out after 1 million fans requested tickets to upcoming shows in cities like Hokkaido, Chiba, Osaka, Miyagi, Aichi, Fukuoka, and Shizuoka. The group’s management team, JYP Entertainment, announced over the weekend that two more shows have been added to TWICE’s tour at the Tokyo Dome in March 2020 – making TWICE the first K-pop girl group to hold two consecutive concerts at the dome. Ticket applications for those dates are being held today.

TWICE consists of nine members: Nayeon, Jeongyeon, Momo, Sana, Jihyo, Mina, Dahyun, Chaeyoung, and Tzuyu. While they debuted in 2015, the group started to gain global attention over the past year with the continued rise of K-pop. They released singles “Happy Happy” and “Breakthrough” over the summer, followed by their eighth EP Feel Special. The Twicelights World Tour hit cities across Asia and North America earlier this year, and is set to cross Japan this fall through early 2020.

The group joins the K-pop global sensation along with girl groups BLACKPINK and ITZY. The former garnered attention after becoming the first K-pop girl group to perform at Coachella, while the latter just announced their debut showcase tour across the U.S. next year. K-pop has been on the rise over the past few years with many artists breaking records; the boyband BTS, also known as Bangtan Boys, became the first K-pop group to play a U.S. stadium this year.
