Sana began her EXPG training in Osaka in 2009, with the intention of becoming a singer in Japan rather than South Korea. She was discovered by a JYP Entertainment staffer in a shopping center during her middle school years and encouraged to participate in the annual JYP Japan audition the next day. Sana was accepted into the JYP trainee program in South Korea in April 2012 after passing the audition. Before making her debut with Twice, she spent almost three years training with JYP. Sana was slated to join a new JYP female group at one point. This new project, however, was canceled, and the group did not make its debut. Sana was a waitress in Got7’s music video for “A” in 2014.

TWICE learned that they’ll be competing against each other on Sports Day in the first episode of season 2 of TDOONG High School.

Sana was a member of the blue team, which also included Jihyo, Chaeyoung, and Tzuyu. Sana stated that she’s a really decent athlete as long as she doesn’t have to run while her team debated who should be the team’s ace.

Sana previously said that she envied Jeongyeon’s athleticism because it allowed her to “run freely,” so it’s no surprise that she didn’t believe she should compete in the TDOONG High School Sports Day’s running events.

Sana believes she’s terrible at jogging, but we think she’s fantastic at everything!
