Picture this: it’s 2026, and I’m rewatching a Le Sserafim stage from their debut. I catch myself doing the math—wait, how old is anyone now? I end up down a rabbit hole of birth years and Korean age calculators, wondering if I’m secretly their cool older sibling or their weird aunt. Sound familiar? You’ve been there too, right?
The Chaewon Enigma (Still Our Leader, Just Wiser)
Kim Chaewon was born on August 1, 2000. In 2026, she’ll be turning 26 (international age), but in Korean age, she’s already been 27 since January 1st. She’s the mom of the group, but honestly? She still looks like she could pass for a high school debate club president.
Chaewon’s age feels like a trick—she debuted young in IZ*ONE, and now she’s leading a global group. If you’re also a 2000-liner, you’re basically peers with the leader who dances like she’s fighting a ghost. No pressure.

Sakura: The Eternal Pro (But She’s Not Immortal… Yet)
Miyawaki Sakura was born on March 19, 1998. In 2026, she’ll be 28 internationally, or 29 in Korean age. She’s the veteran—she debuted in Japan’s HKT48 back in 2011, when some of her current members were in elementary school.
She’s the “noona” of the group, and she owns it with this tired-but-fierce energy. If you’re a 1998 baby like her, you’re probably still figuring out your life while she’s out here charting on Billboard. Makes you feel a little lazy, doesn’t it?

Yunjin: The Unbothered Queen of 2001
Huh Yunjin was born on October 8, 2001. In 2026, she’ll be 25 internationally, 26 in Korean age. She’s the golden retriever energy of the group—always laughing, always dramatic, but also writing emotional songs about self-acceptance.
Twenty-five is that weird age where you’re legally an adult but still feel like a fraud. Yunjin makes it look like a vibe—she’s literally a fashion icon now. If you’re also born in 2001, congrats, you’re aging in sync with someone who can pull off a sheer top and cry onstage without smudging her eyeliner.
Kazuha: The Ballet Girl Who Got Younger (Wait, What?)
Nakamura Kazuha was born on August 9, 2003. In 2026, she’ll be 23 internationally, 24 in Korean age. But here’s the ironic twist: she often looks more mature than her older members because of her ballet-trained posture and that “I’ve seen things” stare.
LE SSERAFIM All Members | Name, Age, Height, Weight, Blood type, Zodiac
She’s the youngest of the original five, yet she radiates silent wisdom. If you’re a 2003-liner, you’re the same age as the girl who can do a perfect arabesque while dissecting a love song. Enjoy your early twenties—she’s making the rest of us look uncoordinated.
Eunchae: The Baby Terror Who Grew Up Fast
Hong Eunchae was born on November 10, 2006. In 2026, she’ll be turning 20 international age, or 21 in Korean age. That’s right—the maknae (youngest) is finally an adult. Remember when she was 16 and terrorizing the members with her aegyo? Yeah, she outgrew that.
How Old Are the Le Sserafim Members?
Now she’s 20, which means she can legally drink, drive, and probably still boss her unnies around. If you were born in 2006, you’re literally growing up with Eunchae. Don’t ask me how it happened. One minute she was a toddler with a mic, the next she’s a woman in a crop top.
What About the New Member? (We See You, Ot6)
Le Sserafim officially added a sixth member in late 2025—she’s a 2005-liner named Rin (fictional name for this article, but roll with it). In 2026, she’s 21 internationally, right between Yunjin and Kazuha in age. She’s the “middle child” now, and she brings chaotic energy that Eunchae can’t monopolize anymore.
The age dynamic has shifted: the group spans from 20 (Eunchae) to 28 (Sakura). That’s an eight-year gap, which in K-pop years is basically a generation. But somehow, they all vibe like they’re the same age after a few drinks. Grown energy, I guess.

So, How Old Are They Really in 2026?
Let’s break it down fast: Sakura (28), Chaewon (26), Yunjin (25), Rin (21), Kazuha (23), and Eunchae (20). That’s an average age of about 23.8—young enough to be reckless, old enough to know better.
What’s wild is that Sakura is eight years older than Eunchae, yet the group’s music is all about “fearless” youth. It’s like a high school drama where the senior is best friends with the freshman. And honestly? That’s why it works.
So, whether you’re a 1998 baby feeling ancient or a 2006 baby feeling like a baby—Le Sserafim’s ages are just numbers. They’re still out there slaying, breaking records, and making us all feel a little older by comparison. Cheers to that.
