#TWICE represents the nine-member South Korean girl group that dominated K-pop’s “third generation” (2015-2020) with irresistibly catchy hooks and adorable concepts.
Formation
TWICE (트와이스) was formed through Mnet’s survival show Sixteen (2015), where JYP Entertainment’s Park Jin-young selected 9 members from 16 trainees:
Korean: Nayeon, Jeongyeon, Jihyo (leader), Dahyun, Chaeyoung Japanese: Sana, Momo, Mina Taiwanese: Tzuyu
The multinational lineup was strategic for pan-Asian appeal.
Debut: “Like OOH-AHH” (October 20, 2015) — broke 100M YouTube views (first K-pop girl group debut to do so)
“Cheer Up” Era (2016)
“Cheer Up” launched TWICE to superstardom:
- Topped charts for 13 consecutive weeks
- “Shy shy shy” hook became national phenomenon
- Song of the Year (2016 Melon Music Awards, Mnet Asian Music Awards)
The TT Dance (2016) cemented their dominance:
- Finger-gun pose went viral globally
- Schools, celebrities, athletes performed it
- 600M+ YouTube views
Concept & Music Style
TWICE specialized in “cute” / “bright” concepts:
- Signature songs: “Cheer Up,” “TT,” “Likey,” “What Is Love?,” “Fancy,” “Feel Special”
- Earworm hooks: Onomatopoeia-heavy (“TT,” “Cheer Up,” “Likey”)
- Choreography: Simple, repeatable moves (great for Random Play Dance)
2019 shift: Transitioned to more mature concepts
- “Fancy” marked turning point (elegant, less aegyo)
- “Feel Special” (2019): Addressed member struggles with fame
Japanese Success
TWICE became the highest-earning K-pop group in Japan (2017-2020):
- 5 consecutive #1 albums on Oricon charts
- Tokyo Dome concerts (2019) — only 3rd K-pop girl group ever
- Japanese members (Sana, Momo, Mina) drove local appeal
“TT -Japanese ver.-” and “One More Time” (original Japanese singles) dominated charts.

- Candybong: Iconic candy-shaped lightstick (3 versions)

2023 Contract Renewals
All 9 members renewed with JYP Entertainment (rare for full 2nd-gen renewal):
- 7-year contracts (2015-2022) extended

Legacy
TWICE proved:
- Multinational groups could unify Asia (Korea-Japan-Taiwan cooperation model)

They paved the way for IVE, NewJeans, LE SSERAFIM’s pan-Asian lineups.
