“Twice” is an unusual K-pop girl group; three of the nine members are in fact Japanese. This past year, they’ve been serving as brand ambassadors, or whatever, for the legendary Far Eastern sports drink Pocari Sweat.
As far as US Wikipedia is concerned, only one member of Twice is notable enough to rate a separate article: Chou Tzu-yu. Tzuyu was born on Taiwan, and her appearance (at sixteen) on a Korean variety show, holding the flag of the Republic of China, caused some grief on the mainland, which continues to argue there is only one China, and Taiwan is only a small part of it.
After about 60 days of turmoil, Tzuyu read an apology on television; it’s not clear how much effect the incident might have had on the 2016 Taiwan general election.
I admit to not entirely comprehending “Signal,” the title track to Twice’s 2017 EP.
