TWICE Trivia which you didn’t know

• They are the first group in JYP Entertainment to have a dedicated TF (Task Force) team. This TF team holds the same rank as the main department and operates independently under the direct leadership of the executives. According to the twicetagram JYP staff list, there are 10 employees in this team. It seems to have benefited from the internal reorganization of JYP Entertainment in 2015. The TF team was launched around the second year of TWICE, and it was disbanded, leading to the restructuring of the company into 3rd artist divisions.
• There were many articles claiming that Park Jin-young described TWICE’s debut concept as “Wild Edge” during their early debut, but in fact, Park Jin-young has never used the term “Wild Edge.” He simply mentioned during an interview at the SIXTEEN production announcement event, “They will inherit the colors of Wonder Girls and Miss A but with a slightly upgraded feel. They will enhance it with elements of hip-hop and wildness. They will continue the healthiness and friendliness of their seniors but become a girl group with an edgier feel.” It was the journalists who conducted the interviews and created the buzzword “Wild Edge” to craft impactful article titles. After TWICE’s debut, journalists started asking about the “Wild Edge” concept during interviews, and it eventually became the accepted description for TWICE’s debut concept. In reality, Park Jin-young, who appeared on TWICE’s V Live broadcast, had no knowledge of the term “Wild Edge.”
• Nayeon, born in 1995, is the eldest, while the mid-year group, born in 1996 (Jeongyeon, Momo, Sana), including the early February birthday of Jihyo (born in 1997), all used informal language with each other. Mina, born in 1997, initially called Jihyo and others “unnie” until May 2017. Eventually, led by Jeongyeon, there was a declaration of unity among the 1996-1997 line members, and from Jeongyeon to Mina, they all became friends. Although there is only a six-month age difference from November 1996 to March 1997… Mina still occasionally refers to Jeongyeon as “unnie.” Dahyun, born in 1998, belongs to the younger line, along with Chaeyoung and Tzuyu, who are of the same age, born in 1999. As they all come from Northeast Asian countries, they have a concept of zodiac signs. Nayeon is in the Year of the Pig, Jeongyeon, Momo, Sana, and Jihyo are in the Year of the Rat  Mina is in the Year of the Cow , Dahyun is in the Year of the Tiger, and Chaeyoung and Tzuyu are in the Year of the Rabbit.
• Age, hierarchy, and formal language concepts are almost non-existent within TWICE. They interact casually from the eldest, Nayeon, to the youngest, Tzuyu, without formalities. Members may refer to each other as “unnie” based on age differences, but they don’t use formal language unless it’s for broadcasting purposes. The 1996-1997 line of five members, born within six months of each other, consider themselves peers, including Mina, born in March. Their meals are also shared without distinctions. However, when it comes to official matters like teaser releases, V Live individual broadcasts, photobooks, and even photocard packaging, everything is meticulously organized by age order, creating a unique contrast.
• When addressing all the members together, they go by their birth order, forming the acronym “Najungmosajimidaetzu.” Even among members of the same age, they consider birthdays, like calling JiMi (Jihyo and Mina) or ChaeTzu (Chaeyoung and Tzuyu). This practice originated from an episode on the show “Knowing Bros,” where Dahyun temporarily left to use the restroom during a regional fan signing event. When they left without realizing Dahyun was missing, it became a decisive reason to always confirm the “Najungmosajimidaetzu” list whenever they do something. This practice has become a symbol for TWICE, and as tradition goes, from teasers to photocard packaging, everything follows the “Najungmosajimidaetzu” order without exception.
• JYP entry dates are as follows: Jihyo – July 15, 2005; Jeongyeon – March 1, 2010; Nayeon – September 15, 2010; Sana/Momo – April 13, 2012; Chaeyoung – June 6, 2012; Dahyun – July 7, 2012; Tzuyu – November 15, 2012; Mina – January 2, 2014. Their training periods are: Jihyo – 10 years and 4 months (3750 days); Jeongyeon – 5 years and 8 months (2060 days); Nayeon – 5 years and 2 months (1862 days); Sana/Momo – 3 years and 7 months (1286 days); Chaeyoung – 3 years and 5 months (1232 days); Dahyun – 3 years and 4 months (1201 days); Tzuyu – 3 years (1070 days); Mina – 1 year and 10 months (657 days). In total, the training period for all 9 members adds up to 14,404 days (39 years, 5 months, 18 days).
• Before their involvement in SIXTEEN, the members practiced separately according to JYP’s policy. Nayeon, Jeongyeon, and Jihyo, who were part of the Sixmix debut team, formed one group. Momo, Sana, and Mina, who were in the Japanese team, formed another. Dahyun and Chaeyoung, who were in the Kids team, trained together with Jeon Somi. Tzuyu was close to other foreign trainees. While they knew each other to some extent before, crying and laughing together during SIXTEEN brought them closer, which has greatly contributed to their current teamwork.
• There are two left-handed members, Jeongyeon and Jihyo, but both of them write with their right hand.
• Birthdays and blood types are evenly distributed within the group. Based on their birthdays, Jihyo (February), Mina (March), Chaeyoung (April), Dahyun (May), Tzuyu (June), Nayeon (September), Jeongyeon – Momo (November), and Sana (December). When it comes to blood types, excluding the rare AB type, there are 4 members with A type (Nayeon, Momo, Mina, Tzuyu), 2 with B type (Sana, Chaeyoung), and 3 with O type (Jeongyeon, Jihyo, Dahyun). Additionally, Chaeyoung has the rare Rh-negative blood type. Momo, who had never had her blood type tested before their debut, had speculated that she might be O type but later found out she is A type in the second episode of “TWICE’s Private Life.” In a recent V Live broadcast, Sana accidentally revealed Momo’s blood type as A, then quickly corrected herself, saying, “No, was it B? O?” It’s worth noting that many Koreans know their own blood types, which is somewhat unusual in other countries where most people don’t pay much attention to it.
• All members use their real names, and even names like Momo and Sana, which might seem like stage names, are their actual birth names. Sana, Mina, and Momo are all Japanese. Sana’s name is written in Kanji as 紗夏, Mina’s Kanji is 南, and Momo’s Japanese writing is もも. However, Jihyo and Jeongyeon underwent name changes. Jihyo’s real name was Jisoo, but she officially changed it to Jihyo before her debut. Jeongyeon changed her name from Kyungwan to Jeongyeon. Additionally, due to her close relationship with her older sister, actress Gong Seungyeon, many people associate her with the name Gong Jungyeon. Yoo Seungyeon and Yoo Jungyeon are their full names. Besides, it’s worth noting that all members have two-syllable names, even among the foreign members who often have longer names.
• All members have parents in good health. Their sibling relationships are as follows: One younger sister for Nayeon, two older sisters for Jeongyeon, one older sister for Momo, an only child for Sana, two younger sisters for Jihyo, one older brother for Mina, one older brother for Dahyun, one younger brother for Chaeyoung, and one older brother for Tzuyu. The members with older brothers are the most common. Interestingly, the members younger than Jihyo do not have any male siblings, and the members older than Jihyo do not have any female siblings.
• Nayeon and Chaeyoung are from Gangdong-gu, Seoul. Jeongyeon hails from Suwon, Gyeonggi Province. Jihyo is from Guri, Gyeonggi Province, and Dahyun is from Seongnam, Gyeonggi Province. The rest of the members are from foreign countries, and there is no member from a non-capital region in South Korea.
• Many TWICE members are dog lovers, and they have several pet dogs. Nayeon has KOOKU, Jeongyeon has BBOSONG and NANANI, Momo has three dogs: PUDDING, LUCKY, and PECO, Sana has ITCHI, Mina has RAY, Dahyun has ARI, Chaeyoung has LOGAL and NAELALLI, and Tzuyu has GUCCI and MINJUNGI. Jihyo, on the other hand, has a cat named PPUYO. While most members are comfortable around animals, Dahyun is the only one with a fear of dogs due to a past incident but adopted a dog named Ari in 2017 to overcome her fear.
• ONCE has uncovered some interesting habits of TWICE members. Mina tends to waddle like a penguin when she’s in a good mood, while Sana is always polite and uses both hands to hold her food. Dahyun covers her eyes with her hair when she’s embarrassed, and Nayeon likes to make binoculars with her hands to see distant things. Momo has a habit of forming a circle with her hands when expressing something and sticking out her tongue when eating something big. Jihyo frequently uses both hands when talking.
• TWICE’s origin traces back to 6MIX, a group that was set to debut under JYP in 2014 with six members. However, due to member departures and the Sewol ferry tragedy, their debut was postponed and ultimately canceled. After the failure of 6MIX, the core members participated in the survival show SIXTEEN, which eventually formed TWICE.
• In the past, JYP Entertainment primarily focused on mainstream appeal and didn’t pay much attention to fan management. However, starting with groups like TWICE and GOT7, they began to prioritize idol management.
• They are known for their extended fan sign events. Typically, fan sign events last for about an hour, with rare instances exceeding two hours. However, when attending a TWICE fan sign event, you should expect a minimum of three hours. This aspect of their fan engagement hasn’t changed, even during their 3rd album promotions. They often begin these events by declaring, “Let’s enjoy a 3-hour conversation.”
  This commitment to extended fan interactions also extends to their concerts, where running over by 30 minutes or more is quite common. On the final day of some concert series, the show has extended by nearly 1.5 hours. This led to slogans like “TWICE stay than the last train” during their second concert series.
• The number 2 seems to have significant associations, possibly related to their team name. During a V Live broadcast, JiHyo mentioned “February 22nd TWICE Day,” indicating that the agency pays attention to the number 2. Initially, TWICE gained an image of being second place, frequently ranking as runner-up on music shows and at athletic events. However, starting from their second mini-album “CHEER UP” (which also includes the number 2), they shattered various records, improving their image. Now, they even utilize the number 2 by offering signed CDs to ONCE members with membership numbers 2, 22, 222, and 2222 during the official fan club formation event.
• During their debut days, the Korean language proficiency among TWICE members ranked as follows: Sana, Momo, Mina, and Tzuyu. However, Mina, who had the shortest stay in Korea, showed rapid improvement in her Korean skills. She has already surpassed Momo in proficiency and sometimes even demonstrates better skills than Sana. It’s possible that Momo’s slower progress might be unrelated to language abilities but rather due to her extended stay in Korea. Recently, even when Japanese members are together, they converse in Korean. In fact, there have been instances of Momo and Sana conversing in Korean while shopping during their vacation in Hawaii after the TWICELIGHTS concert.
• The hometowns of the Japanese members are all in the Kansai region. Sana is from Osaka, Momo is from Kyoto, and Mina lives in Kobe, which are fairly close to each other.
• All 9 members of the group enjoy exercising. As a result of their dedication to exercise, all the members have well-defined muscles and abs. Among them, Nayeon is known to frequently practice Pilates, and Jeongyeon used to exercise regularly before suffering from a neck disc problem. Momo and Jihyo are particularly well-known exercise enthusiasts among ONCEs, and the other members also often visit the gym.
• Despite being a group with 9 members from various countries, TWICE has very few members who engage in solo activities. They have not ventured into unit activities either. Considering that TWICE debuted in 2015, which means they are approaching their 10th anniversary in 2022, it’s quite unusual for a long-standing multi-member group like them not to explore new areas such as solo music releases, acting, YouTube, musicals, or units. When asked about this in an appearance on Radio Star, they mentioned that they believe focusing on full-group activities would be jeopardized if they started solo or unit activities. However, some communities speculate that it might be due to controversies surrounding the main producer, Park Jinyoung’s. singing abilities of TWICE, or concerns that a member becoming exceptionally popular, similar to Suzy in Miss A, could overshadow the other members’ images. Nevertheless, in May 2022, Nayeon’s solo album was announced, marking the start of TWICE’s first solo activity. In the latter half of the year, there were also hints of the first unit activity with the Japanese members—Mina, Sana, and Momo—under the name “MISAMO,” which was registered as a trademark. On January 25, 2023, they released their debut song “Bouquet,” marking the beginning of their unit activities.
• As of now, TWICE has not released Korean or Japanese albums in January, making it the only month without album releases.
• The average height of the members is 163.4 cm.
• From their debut until the latter half of 2017, all the members lived in the same dorm. In the dorm they used until 2017, Nayeon, Jihyo, Mina, and Sana shared the largest room, Dahyun, Chaeyoung, and Tzuyu shared the middle room, and Jeongyeon and Momo had the smallest room. However, it wasn’t strictly divided, and they often slept in each other’s beds depending on their schedules or circumstances. The four-member room was considered the messiest since it housed a lot of belongings, especially the personal items of foreign members Mina and Sana. As for the four-member room, the average bedtime was around 3 to 4 AM. While part of it was due to late schedules, most of them stayed up late chatting and talking. The three-member room was used by the catering team, and the upper bunk of the two-level bed was used by Chaeyoung and the lower bunk by Dahyun, while Tzuyu had a separate bed next to it. It was usually the quietest room, but older members like Nayeon and Jihyo would occasionally come in and ask them to play. The two-member room was shared by Jeongyeon and Momo, who slept together on the same bed with a large doll placed between them. They became close and were even referred to as a “couple” within the group. Based on what has been revealed through TWICE’s elegant private lives and broadcasts like V LIVE, it appears that their dorms have a duplex structure. The living room is spacious enough to accommodate all nine members comfortably, and in addition to the rooms where the members stay, there is a separate dressing room, making it quite a decent living environment. At one point, it was reported that TWICE moved to a new dorm in the latter half of 2017 in sync with JYP Entertainment’s office relocation. However, this turned out to be misinformation. It was due to a misunderstanding during a V LIVE broadcast about changed roommates; they were referring to their Japanese dorm roommates. In their most recent appearance during the “Alcohol-Free” promotion in June 2022, Momo and Jeongyeon still appeared to be roommates.
• After Nayeon’s solo debut in June 2022, she was confirmed to be living with Momo in an apartment with a view of the Han River, which suggests that they have moved out of the dorm. As for the other members, Jeongyeon is living with her older sister Gong Seungyeon, as of January 2022, which means they had been living together for about six months. Jihyo is currently known as the only member who has moved out and is living independently. Gong Seungyeon mentioned in January 2023 that she had been living with Jeongyeon for about two years since Jeongyeon’s solo debut in August 2020. This suggests that they have all moved out of the dorms after the “Alcohol-Free” promotions.
