Birthday of Won-young Jang

Won-young Jang, often stylized as Jang Wonyoung or simply Wonyoung, was born on August 31, 2004, in Ichon-dong, Yongsan-gu, Seoul, South Korea. At just 21 years old in 2025, she stands tall at 173 cm (5’8″), earning her the affectionate nickname “Giant Baby” due to her youthful face paired with a model-like figure. Her blood type is O, and she’s known for her multilingual skills, speaking Korean, English, and some Japanese and Chinese.

Wonyoung’s journey to stardom began in 2018 when she competed on the survival show Produce 48 at the tender age of 13. She emerged as the center and youngest member of the project group IZONE, debuting with the hit “La Vie en Rose.” During her time with IZONE (2018-2021), she showcased her vocals, rap, and dance prowess in tracks like “Fiesta” and “Panorama,” helping the group achieve massive success both in Korea and internationally.

After IZ*ONE disbanded, Wonyoung didn’t miss a beat. She redebuted in December 2021 as a member of IVE under Starship Entertainment. As IVE’s visual, lead dancer, and sub-vocalist, she’s been integral to chart-toppers like “ELEVEN,” “LOVE DIVE,” “After LIKE,” and “I AM.” Her role extends beyond music; she’s an MC for shows like Music Bank, a brand ambassador for luxury labels like Bvlgari and Miu Miu, and even dabbled in acting with cameos in dramas.

Off-stage, Wonyoung is admired for her positive personality, fashion sense, and philanthropy. She’s involved in campaigns for education and youth empowerment, and her older sister, Jang Da-ah, is also in the entertainment industry. With millions of followers on Instagram and X (formerly Twitter), Wonyoung’s influence spans music, fashion, and beauty, making her a true Gen Z icon. As she celebrates her 21st birthday, fans reflect on her growth from a wide-eyed trainee to a confident artist who’s already achieved so much.

First, choose a venue: Opt for a K-pop cafe, community center, or even a park picnic. In cities like Seoul or Chengdu, fans have hosted events at birthday cafes with themed decor.

Food and drinks: Serve Korean snacks like tteokbokki or strawberry-themed treats, tying into her fresh image. For drinks, make pink lattes or mocktails.

Highlight: A group birthday song video to post online, or collect messages for a fan letter book to send to Starship Entertainment.

Budget wisely: Allocate for decor ($50-100), food ($100+), and perhaps a small gift pool. Promote safety—follow COVID guidelines if applicable.

End with a giveaway: Raffle IVE merch or custom stickers. Fan parties like the photostrip events in Indonesia show how fun and bonding these can be. With planning, your party will be a hit, spreading birthday cheer far and wide.
