On January 3, a new K-pop girl group named Kep1er released their debut EP First Impact , kicking off 2022 and their career in a big way. A multinational group formed from a televised K-pop competition show, Kep1er has gained attention and fans from around the world. Here’s what you need to know about them. Who they are Kep1er is a nine-member team, currently managed by South Korean music label, Swing Entertainment. The members were all born between 1996 and 2005. The members are from East Asia, with six – Choi Yu-jin, Kim Chae-hyun, Kim Da-yeon, Huening Bahiyyih, Seo Young-eun and Kang Ye-seo – hailing from South Korea. Of the remaining three members, Mashiro Sakamoto and Hikaru Ezaki are Japanese, while Shen Xiaoting hails from China. Their origins in a competition The members of Kep1er came together last year on Girls Planet 999, a competition TV show on South Korean broadcaster Mnet. A follow-up to its highly popular, but rigged, Produce series, it was based around different “planets” featured throughout the show, and featured 99 competitors from South Korea, Japan, China, Taiwan and Hong Kong, split initially by nationality and ethnicity. Like other groups produced by Mnet’s competition series, Kep1er’s time together is set to be rather short, with a planned lifespan of two and a half years. Girls Planet 999 will be followed by a male-focused show, Boys Planet 2022.

Shen Xiaoting and Kim Da-yeon have previously competed in various Produce series in South Korea and China. Mashiro Sakamoto, Kim Chae-hyun and Huening Bahiyyih have connections to other K-pop acts and labels.
