TWICE is a globally acclaimed nine-member girl group from South Korea, formed by JYP Entertainment in 2015. The group consists of Nayeon, Jeongyeon, Momo, Sana, Jihyo, Mina, Dahyun, Chaeyoung, and Tzuyu. Since their debut on October 20, 2015, with the mini-album The Story Begins, they have become one of the best-selling K-pop acts of all time, earning the prestigious title of "The Nation's Girl Group."

The group's formation was the result of the competitive reality survival show SIXTEEN. While the show was originally intended to select seven members, JYP Entertainment founder J.Y. Park made the historic decision to add two more—Tzuyu, due to her immense popularity with the audience, and Momo, for her indispensable performance skills. This nine-member lineup has remained intact for nearly a decade, a rare feat in the K-pop industry known for frequent lineup changes.

Nayeon: The Iconic Center and Eldest Member

Im Na-yeon, professionally known as Nayeon, was born on September 22, 1995, in Seoul, South Korea. As the oldest member of the group, she often sets the tone for TWICE’s vibrant and energetic image. In the team, she serves as the Lead Vocalist and Center.

Nayeon was the first member to be announced for TWICE during SIXTEEN, and her experience as a trainee dates back to 2010. She is widely recognized for her "bunny-like" smile and her bright, stable vocals that often open the group's hit songs. Her presence is so central to the group's identity that she is frequently referred to as the "Face of the Group."

In June 2022, Nayeon became the first member of TWICE to debut as a soloist with the EP IM NAYEON. The title track "POP!" became a global viral sensation, showcasing her ability to carry a stage independently. She followed this success in 2024 with her second mini-album NA, featuring the title track "ABCD," which explored a more mature, Y2K-inspired R&B sound. Beyond her performance roles, Nayeon is a frequent songwriter for the group, contributing lyrics to tracks like "Rainbow," "24/7," and "Depend on You."

Jeongyeon: The Powerful Vocalist with Heart

Yoo Jeong-yeon was born on November 1, 1996, in Suwon, South Korea. As a Lead Vocalist, she is celebrated for her stable, husky, and versatile voice that provides a grounded contrast to the group's higher-pitched melodies.

Jeongyeon’s journey in TWICE has been marked by resilience. Between 2020 and 2021, she took several hiatuses to focus on her mental health and recover from a neck injury. Her return to full group activities was met with overwhelming support from the global fandom, ONCE. Her ability to adapt to various concepts—from the "girl crush" aesthetic of their early days to the elegant style of their recent eras—makes her a vital asset to the group's dynamic.

On the creative front, Jeongyeon has participated in writing lyrics for several TWICE songs, including "Love Line," "Sweet Talker," and "LaLaLa." In recent years, she has also explored variety hosting and solo projects, further demonstrating her multifaceted talents. Her fans often associate her with the dog emoji, reflecting her loyal and protective personality within the group.

Momo: The Main Dancer and Performance Powerhouse

Hirai Momo, known simply as Momo, was born on November 9, 1996, in Kyōtanabe, Kyoto, Japan. She is one of the group's three Japanese members. Her role in TWICE is Main Dancer and Sub-Vocalist, and she is widely regarded by industry experts as one of the best dancers in K-pop history.

Momo's story is one of the most dramatic in K-pop lore. She was actually eliminated during the final episodes of SIXTEEN, only to be brought back by J.Y. Park in the finale because the group lacked a definitive performance anchor. This decision proved to be visionary, as Momo’s sharp choreography and stage presence became a signature of the TWICE experience.

In 2023, Momo debuted as part of TWICE’s first sub-unit, MISAMO, alongside fellow Japanese members Sana and Mina. Their debut Japanese mini-album Masterpiece showcased a sophisticated, art-focused concept. Momo is also active in the fashion world, serving as a brand ambassador for luxury labels like Miu Miu. Her dance tutorials and choreography videos continue to garner millions of views, maintaining her status as a performance icon.

Sana: The Charismatic and Energetic Spirit

Minatozaki Sana was born on December 29, 1996, in Osaka, Japan. She serves as a Sub-Vocalist and is often cited as the member with the most natural charisma and variety show talent.

Sana became a household name in South Korea in 2016 thanks to her "Shy Shy Shy" line in the hit song "Cheer Up." The line went viral, sparking a national craze and cementing TWICE's status as a top-tier group. Sana is known for her clumsy yet adorable personality, earning her the nickname "No Sana, No Life."

Beyond her cute image, Sana has evolved into a sophisticated artist. She is a key member of the MISAMO sub-unit and has contributed to the lyrics of songs like "Shot thru the Heart" and "Do What We Like." In 2024, she was particularly active in high-fashion circles, representing brands like Prada and Graff. Her ability to switch from a bubbly "hamster" persona to a high-fashion model demonstrates her incredible range.

Jihyo: The Resilient Leader and Main Vocalist

Park Ji-hyo, born on February 1, 1997, in Guri, South Korea, is the leader and Main Vocalist of TWICE. Her journey is defined by unparalleled dedication; she trained under JYP Entertainment for ten years before finally debuting with TWICE.

As the leader, Jihyo is the bridge between the members and the company. She is known for her powerful, soulful vocals and her high-energy performances. Her stage presence is often described as "tireless," as she consistently gives 100% effort in every choreography.

Jihyo officially debuted as a soloist in August 2023 with the mini-album ZONE and the title track "Killin' Me Good." The album allowed her to showcase a darker, more rhythmic side of her artistry. Jihyo is also one of the group's most prolific songwriters and composers, having worked on tracks like "Cactus" (which she also composed) and "Trouble." Her leadership was instrumental during the group's contract renewal in 2022, ensuring all nine members stayed together to continue their legacy.

Mina: The Elegant "Black Swan"

Myoui Mina was born on March 24, 1997, in San Antonio, Texas, but raised in Kobe, Japan. She holds both American and Japanese citizenship. As a Main Dancer and Sub-Vocalist, Mina brings a unique elegance to TWICE, stemming from her eleven years of classical ballet training.

Mina is often called the "Black Swan" of the group because of her graceful movements and quiet, sophisticated aura. Despite her introverted nature, her presence on stage is magnetic. In 2019, she took a significant break from activities due to severe anxiety, a move that was praised for bringing awareness to mental health in the K-pop industry. Her return was a triumphant moment for the group and their fans.

Mina is the third member of the MISAMO sub-unit. Her vocal color is often described as "ethereal" and "melodic," providing a soft layer to the group's tracks. She is also a representative for global brands like SK-II and Fendi, frequently appearing at international fashion weeks. Her hobby of gaming and LEGO building has also made her relatable to fans who appreciate her "indoor-person" lifestyle.

Dahyun: The Witty Rapper and Songwriter

Kim Da-hyun was born on May 28, 1998, in Seongnam, South Korea. She serves as the Lead Rapper and Sub-Vocalist. Before her debut, she gained fame through a viral "Eagle Dance" video at her church, which showcased the comedic timing and bold personality that would make her a variety show star.

Dahyun is often the "mood maker" of TWICE. She has a unique ability to spot cameras even in crowded environments, a talent that has become a running joke among fans. However, her most significant contribution to the group in recent years has been her songwriting. Dahyun has written lyrics for more TWICE songs than almost any other member, including "Queen," "Scandal," "Tick Tock," and "Gone."

In 2024 and 2025, Dahyun began expanding her horizons into acting, being cast in several film and television projects. Her sharp wit and linguistic skills (she is particularly diligent in learning foreign languages to communicate with international fans) make her an essential bridge for TWICE’s global activities.

Chaeyoung: The Creative Artist and Main Rapper

Son Chae-young was born on April 23, 1999, in Seoul, South Korea. She is the Main Rapper and Sub-Vocalist. Chaeyoung is often viewed as the "indie" soul of the group, with a deep interest in drawing, poetry, and unconventional fashion.

Known as the "Strawberry Princess," Chaeyoung joined JYP at a young age and quickly stood out for her rapping skills and artistic flair. She was the first member to have her own song-writing credits on a TWICE album with the song "Precious Love" (rap making). Since then, she has contributed to numerous tracks, such as "Strawberry," "Handle It," and the Korean version of "The Feels."

Chaeyoung is celebrated for her unique vocal tone and her ability to deliver both aggressive rap verses and melodic vocals. She has expressed a desire to explore various musical genres, often sharing her own artwork and curated playlists with fans. Her tattoos and personal style choices have made her an icon of self-expression within the K-pop scene.

Tzuyu: The Visual Maknae and Global Icon

Chou Tzuyu was born on June 14, 1999, in Tainan, Taiwan. She is the youngest member (maknae) and serves as the Lead Dancer, Sub-Vocalist, and Visual. Tzuyu was added to the final lineup of TWICE due to her overwhelming popularity during SIXTEEN.

Tzuyu is consistently ranked as one of the most beautiful faces in the world by various international outlets. However, her career is defined by much more than her looks. Over the years, she has shown significant improvement in her vocal stability and dance precision. Her tall stature and elegant lines make her a standout in the group’s formations.

In September 2024, Tzuyu made her long-awaited solo debut with the mini-album abouTZU. The title track "Run Away" showcased her growth as a vocalist and her ability to command the spotlight. As the only Taiwanese member, she holds a special place in the hearts of Chinese-speaking fans and has been a key driver of TWICE’s massive popularity across Asia.

The Significance of "NaJeongMoSaJiMiDaChaeTzu"

Their early hits like "TT," "Likey," and "What is Love?" became viral sensations, with their point choreographies being imitated by millions worldwide.

As the group matured, they transitioned from a "cute" concept to more sophisticated sounds in albums like Eyes Wide Open (2020), Formula of Love: O+T=<3 (2021), and With YOU-th (2024). In 2024, their album With YOU-th reached number one on the Billboard 200, a milestone that solidified their status as a global powerhouse.

In 2025, TWICE continued their dominance with the "This Is For" World Tour, performing in stadiums across North America, Europe, and Asia. Their collaboration with American rapper Megan Thee Stallion on the track "Strategy" further demonstrated their ability to cross musical boundaries and appeal to a diverse international audience.
