Twice (Korean: 트와이스; Japanese: トゥワイス), is a South Korean girl group formed by JYP
Entertainment. The group is composed of nine
members: Nayeon, Jeongyeon, Momo, Sana, Jihyo, Mina, Dahyun, Chaeyoung, and Tzuyu. Twice
was formed under the television program Sixteen (2015) and debuted on October 20, 2015, with
the extended play (EP) The Story Begins.[3]
Twice rose to domestic fame in 2016 with their single "Cheer Up", which charted at number one on
the Gaon Digital Chart, became the best-performing single of the year, and won "Song of the Year"
at the Melon Music Awards and Mnet Asian Music Awards.[4][5][6] Their next single, "TT", from their
third EP Twicecoaster: Lane 1, topped the Gaon charts for four consecutive weeks. The EP was the
highest selling K-pop girl group album of 2016.[7][8] Within 19 months after debut, Twice had already
sold over 1.2 million units of their four EPs and special album[9][10]; in 2019, they became the best-
selling Korean girl group of all-time.[11][12] The group has sold over 9 million albums in South Korea
and Japan as of July 2020.[13] In 2020, Twice signed with Republic Records for American promotions
as part of a partnership with JYP Entertainment.[2]
The group debuted in Japan on June 28, 2017 under Warner Music Japan, with the release of a
compilation album titled #Twice. The album charted at number 2 on the Oricon Albums Chart with
the highest first-week album sales by a K-pop artist in Japan in two years.[14][15] It was followed by the
release of Twice's first original Japanese maxi single titled "One More Time" in October. Twice
became the first Korean girl group to earn a platinum certification from the Recording Industry
Association of Japan (RIAJ) for both an album and CD single in the same year.[16][17] Twice ranked
third in the Top Artist category of Billboard Japan's 2017 Year-End Rankings.[18] They have been
dubbed the next "Nation's Girl Group",[19] and their point choreography—including for "Cheer Up",
"TT" and "Signal"—became dance crazes and viral memes imitated by many celebrities.[20][21][22][23]
