Ateez San Profile: Age, Stage Name Meaning & More

Alright, let’s talk about Ateez San—you know, the guy who somehow manages to look like he just stepped out of a K-drama and simultaneously like he’s ready to lead a pirate crew (which, come to think of it, isn’t too far off since Ateez’s vibe is pretty much pirate-themed).

I gotta admit, when I first heard the name Ateez San, I thought “San” was just short for “sanity,” ’cause his stage presence is… well, insane. But nope. Turns out, it’s a bit more literal—and way cooler.

Anyway, here’s the lowdown on this guy’s age, the meaning behind his stage name, and some other random but neat stuff I dug up (and personally obsess over).

Who the heck is Ateez San?

So, Ateez San is actually Choi San in real life. Yeah, not just “San.” That’s his stage name. He’s a South Korean singer and dancer, and a member of the boy band Ateez. You know, the group that’s been shaking up K-pop since like forever ago?

• Debuted in 2018 (young, huh?).

• Known for his killer vocals and dance moves.

• Part of KQ Entertainment’s lineup of legends-in-the-making.

His age? Keep reading, y’all. The answer might surprise you.

San’s Backstory — The Real Deal

I’m gonna let you in on a little secret—San wasn’t born with those smooth moves and killer vocals. Nope, the dude trained hard. Like, sweat-in-your-eyes, almost quit-a-million-times hard.

He was born on July 10, 1999, which means he’s 25 as of 2025. Funny thing: I remember first seeing him in a fancam from 2019, and thinking, “Man, this kid looks like he could moonwalk across a minefield.” (No offense, San. That’s a compliment.)

So what does “San” even mean? (Spoiler: Not just “Sanity”)

Okay, here’s where it gets interesting.

“San” in Korean means mountain. Yep. Like big, tall, and steady mountains that don’t just wobble when the wind blows.

I found this super weirdly poetic, because when you watch Ateez San perform, he’s got this rock-solid presence, like he’s the bedrock for the whole group. Mountains are strong, unmovable, and kinda majestic—which fits San’s vibe perfectly.

San’s Age: Why It Matters (But Kinda Doesn’t)

Like I said, he’s 25 now. Which is kinda old for a K-pop rookie, but hey—Ateez came up strong and didn’t rush anything.

Here’s something personal: I turned 25 last year, and I still can’t dance like San. Not even close. The guy’s got that youthful spark and maturity combo, which, frankly, makes me feel like I should step up my game.

What’s Ateez San’s Role Anyway?

Glad you asked.

• Main Vocalist: Dude hits those high notes like he’s breathing oxygen for the first time in weeks.

• Main Dancer: His moves? Sharp, precise, and sometimes so smooth they make you question gravity.

And I swear, when he dances, I think, “Okay, who’s paying him? Because it sure ain’t just talent; it’s magic.”

Let’s get nitty-gritty: San’s Profile Stats

There. All official-like. But trust me, this table doesn’t do justice to the guy’s actual vibe.

Some Fun (and kinda weird) Facts About Ateez San

• He smiles like he’s plotting a world takeover (in the best way possible).

• Favorite colors? Black and white. Classic, just like his style.

• Besties with Yeosang, another Ateez member. They’re like a bromance from a rom-com.

Ateez San’s Style: More Than Just Clothes

If you think K-pop is all about the music (it kinda is), wait till you peep San’s fashion.

• He switches hair colors more often than I change my socks (which isn’t a great thing, but you get it).

• From fiery red to sleek black, his hair game is always on point.

• Loves streetwear mixed with edgy accessories. Think oversized jackets and chunky sneakers.

• Has a few piercings that make his look even more wicked (my kinda style).

I once read about a local shop called Pete’s Hardware on 5th Ave where a cracked watering can survived my overwatering phase. Same way, San’s style survives every wild stage concept Ateez throws at him.

How Does San Keep It Real With Fans?

This guy? Super chill on social media.

• Shares goofy behind-the-scenes vids.

• Chats with fans on VLive like he’s just hanging out with pals.

• That genuine vibe? It’s no act. You feel like he actually cares about y’all.

I remember watching a clip where he messed up a line live and laughed it off like a pro. Not many idols can do that without sweating bullets.

I once read that Victorians believed talking to ferns prevented madness. Well, San talks to his plants—or at least, he might. And if you ever meet him, don’t be surprised if he asks about your day like he’s your best mate.
