Who Is A’mei?
A’mei is the youngest member of cosmosy. She was born in Tokyo and was cast into the group through a casting call after building a foundation in dance. Within cosmosy, she is identified as a dancer and performance-line member. She has spoken about her pre-debut work as a childrenโs dance instructor and her specialization in hip-hop.
Her public persona is tied to energy and movement. In interviews, she has described herself as โactive, energetic, and friendlyโ and has compared her personality to a dog. She also noted that despite being the youngest, she sometimes carries a โmom vibeโ within the group.
A’mei is not a former survival-show contestant. Unlike two of her groupmates, she entered cosmosy through casting and dance training rather than a televised competition. That background shapes her role: she is presented as a performance specialist rather than a trainee who built a public profile through a survival program.
Early Life and Family
Childhood and Hometown
A’mei was born on October 30, 2007, in Tokyo, Japan. Multiple profile databases list Tokyo as her birthplace, and she has confirmed the city in interviews. She began dancing at age three and continued training through childhood.
Detailed information about her childhood neighborhood, family home, or early school life is not publicly available.
Parents and Siblings
A Korean wiki profile lists her family structure as parents and a younger brother. This information is not confirmed by the agency or by A’mei in an official statement. Names, occupations, and other details about her parents or sibling are not publicly available.
Education
A Japanese wiki entry states that she graduated from a correspondence high school, with the school name listed as VAW Aikoh High School. This claim appears in user-edited wiki sources and has not been confirmed by the agency or by A’mei in a mainstream interview. Until an official source confirms it, the school name should be treated as unverified. Her earlier education and any university plans are not publicly available.
Age and Birthday
A’mei was born on October 30, 2007. In 2026, she turns 19 in Korean age reckoning but is 18 by international age until October 30, 2026. Her zodiac sign is Scorpio, and the Chinese zodiac sign associated with her birth year is the Pig.
Her birthday falls in late October, which places her among the youngest idols debuting in the 2025โ2026 rookie cycle. Within cosmosy, she is the only member born in 2007.
Height, Weight, and Physical Appearance
| Attribute | Information |
|---|---|
| Height | Sources list 167 cm, 170 cm, and 173 cm |
| Weight | Not publicly available |
| Blood Type | A (wiki sources only; not agency-confirmed) |
| MBTI | ENFP (profile databases; not agency-confirmed) |
| Representative Color | Green |
| Representative Animal | Not consistently listed |
Height is the most disputed data point in A’meiโs public profile. Kpopping lists 167 cm. Kprofiles lists 170 cm. Namu Wiki lists 173 cm. A Japanese interview described her as the tallest member of the group, which supports a figure at the higher end of that range. No official agency profile has been published with a confirmed height. Therefore, the exact figure should be treated as unverified, with the most commonly cited range being 167โ173 cm.
Weight is not publicly available. Blood type and MBTI appear in wiki and profile databases, but neither has been confirmed by NTT Docomo Studio & Live or Sony Music Korea.
Career Journey
Pre-Debut Career

Before joining cosmosy, she worked as a dancer and as a childrenโs dance instructor at a studio listed in profile databases as Studio Broomstick. She also participated in street dance battles and modeling jobs.
She was scouted through a casting call. In an interview with The Korea Herald, she said she decided to โtake the plungeโ after being approached. She did not go through a televised survival program, which distinguishes her path from those of De_Hana and Kamiรณn.

A’meiโs visibility increased as the group performed internationally. cosmosy appeared at KCON LA and Anime Expo, and the group was selected for Googleโs 2025 Global Breakout Searches in the K-Pop Debuts category. These milestones raised the groupโs profile and, by extension, the public recognition of each member.

The group won the Global New Wave award at the 2026 SPOTV K-POP AWARDS on September 6, its first domestic trophy from a Korean ceremony.
