OURBIRTHDAY Members Profile 2026: Age, Bio & Interesting Facts
The K-Pop industry has welcomed a fresh new voice in 2026 with the arrival of OURBIRTHDAY (아워벌스데이), a multinational girl group that carries the legacy of JYP Entertainment’s renowned “girl group dynasty.” Launched under the independent subsidiary INNIT Entertainment, OURBIRTHDAY represents JYP’s first new girl group project since NMIXX debuted in 2022—marking a four-year gap that has only intensified anticipation for this seven-member ensemble.
OURBIRTHDAY is a seven-member multinational K-Pop girl group under INNIT Entertainment, a subsidiary of JYP Entertainment. They debuted with the pre-debut single “HUNGRY (Side A)” on July 22, 2026. The three revealed members are Cho Hyejin (South Korea), Baby/Cherysha (Taiwan), and Achiraya (Thailand). Their name means “enjoying every day like a birthday.”
What sets OURBIRTHDAY apart is not just their connection to one of K-Pop’s “Big 4” agencies, but their unique conceptual identity. The group’s name embodies the philosophy of “enjoying the present moment as if every day is a birthday,” aiming to redefine ordinary daily life with vibrant energy through their music and performances. Rather than following the traditional debut rollout, INNIT Entertainment took a narrative-driven approach, gradually unveiling the group’s identity through logo reveals, character animations, world-building videos, and cake-inspired visual concepts before introducing the members themselves.
As of July 2026, three members have been publicly revealed—Cho Hyejin from South Korea, Baby (Cherysha) from Taiwan, and Achiraya from Thailand—with four additional members yet to be announced. The group officially commenced their pre-debut activities on July 22, 2026, with the release of their first digital single “HUNGRY (Side A),” followed by their debut music broadcast performance on Mnet’s M Countdown on July 23. This OURBIRTHDAY members profile 2026 guide provides a comprehensive look at everything fans need to know about this exciting new group.

Who Is OURBIRTHDAY?
OURBIRTHDAY is a seven-member multinational girl group under INNIT Entertainment, an independent subsidiary of JYP Entertainment—one of South Korea’s most prestigious entertainment companies, known for producing iconic girl groups like Wonder Girls, miss A, TWICE, ITZY, and NMIXX. The group’s name, pronounced “Ah-wuh-beo-seu-dei” in Korean, carries the beautiful meaning of “hoping to dye everyday life with the excitement of a birthday”.
The group’s conceptual identity revolves around cake-inspired characters, with each member assigned a unique color and dessert flavor that reflects their personality and visual concept. This whimsical, celebratory theme aligns perfectly with their name and mission to make every day feel special.
OURBIRTHDAY’s debut strategy is notably unconventional. Rather than a traditional full-group debut, INNIT Entertainment opted for a “pre-debut” approach, first introducing three members who would promote the group’s inaugural single before the full seven-member lineup is eventually revealed. This gradual rollout has generated sustained buzz and curiosity, allowing fans to connect with each member individually before the group’s complete formation.
Group History
Formation and Pre-Debut
OURBIRTHDAY’s journey began taking shape in early 2026 when JYP Entertainment first teased the project through logo videos. The group was developed under INNIT Entertainment, a subsidiary created to manage this new girl group initiative. What made this pre-debut phase particularly distinctive was the agency’s decision to build anticipation through a carefully orchestrated narrative.
In July 2026, INNIT Entertainment released a series of cake-inspired character posters featuring three animated personas: Cherrysha (cherry cake), Groo Blue (matcha cake), and I-Yat (blueberry cake). These characters served as conceptual avatars before the actual members were unveiled, creating a sense of mystery and world-building that is increasingly popular in modern K-Pop marketing.
Official Debut
On July 15, 2026, INNIT Entertainment dropped the teaser film “ERROR 502: Bad Gateway,” which officially revealed the first three members of OURBIRTHDAY in live-action. The video featured Cho Hyejin, Baby, and Achiraya in a futuristic, mysterious setting, culminating in the three members gathering around a cake bearing the group’s name.
The group’s pre-debut digital single “HUNGRY (Side A)” was released on July 22, 2026, at 6 PM KST across all major online music platforms. The title track, which shares the same name, expresses the members’ relentless passion and ambition for the stage through explosive sound and powerful performances. The song was written by Kang Eunjeong, EXY (of WJSN), and sohlhee, with composition by Jake K (ARTiffect), Sean Fischer, Kyler Niko, and Lucia Calcines.
OURBIRTHDAY made their first music broadcast appearance on Mnet’s M Countdown on July 23, 2026, marking their official entry into the K-Pop industry.
Breakthrough Success
As a newly debuting group in July 2026, OURBIRTHDAY is in the earliest stages of their career. However, their pre-debut buzz has been remarkable. The reveal of Taiwanese member Baby (Cherysha) generated significant media attention across both South Korea and Taiwan, with her being hailed as the second Taiwanese female idol under JYP Entertainment after TWICE’s Tzuyu. Cho Hyejin’s victory on KBS 2TV’s audition program The DDANDDARA has also brought considerable attention to the group.
Major Career Milestones
- July 2026: Character posters and concept videos released
- July 15, 2026: “ERROR 502: Bad Gateway” teaser reveals first three members
- July 22, 2026: Release of pre-debut digital single “HUNGRY (Side A)”

Recent Activities
OURBIRTHDAY is currently promoting their pre-debut single “HUNGRY (Side A)” with the three revealed members. The group continues to build anticipation for the eventual reveal of their remaining four members and their official full-group debut.
Agency and Management
OURBIRTHDAY is managed by INNIT Entertainment, an independent subsidiary of JYP Entertainment. This structure is significant because it marks a departure from JYP’s traditional approach of debuting groups directly under the main label. INNIT Entertainment was established specifically to manage this new girl group project, giving OURBIRTHDAY its own dedicated management team while still benefiting from JYP Entertainment’s extensive industry resources, production capabilities, and global network.
JYP Entertainment, founded by Park Jin-young in 1997, is one of South Korea’s “Big 4” entertainment companies alongside HYBE, SM Entertainment, and YG Entertainment. The company has a storied history of producing successful girl groups, including Wonder Girls (2007), miss A (2010), TWICE (2015), ITZY (2019), and NMIXX (2022). OURBIRTHDAY represents JYP’s first new girl group in four years, making their debut particularly significant.
The decision to debut OURBIRTHDAY under a subsidiary rather than directly under JYP Entertainment has sparked various interpretations among industry observers. Some view it as JYP’s strategy to experiment with new concepts and marketing approaches, while others see it as a way to provide the group with more focused management attention. Regardless, the connection to JYP Entertainment ensures that OURBIRTHDAY has access to top-tier production, choreography, and promotional support.
As of July 2026, specific contract details and lengths have not been publicly disclosed.
Complete Member Profiles
As of July 2026, only three of the seven OURBIRTHDAY members have been publicly revealed. The following profiles are based on verified public information available at the time of writing. Information about the remaining four members is not yet publicly available.

Baby was born Hsieh Chia-hsuan on February 10, 2009, in Kaohsiung, a major port city in southern Taiwan. Growing up in Kaohsiung, she developed a passion for dance at an early age, eventually becoming a student at the “Apple Family” (蘋果家族) children’s street dance studio in Kaohsiung. The Apple Family is known for training young dancers, and Baby stood out as one of its promising talents.
In addition to her dance training, Baby was also a child model, gaining early exposure to the entertainment industry. Her social media presence during her childhood years accumulated a following, though her accounts mysteriously stopped updating for four to five years before her debut with OURBIRTHDAY—a period when she was secretly training in South Korea.
