TL;DR: The Olive Young x Sanrio “City Log” pop-up is running at Olive Young N Seongsu through September 30, 2026 — free to enter, no reservation app required, just a walk-in line. I’d braced myself for a long wait based on how big this collab is (321 products across 81 brands), but I was in after about 10 minutes on a weekday. The store is split into two halves: a retail “MD zone” where actual K-beauty brands sell Sanrio-themed products, and a separate experience zone with a mini arcade game, a gacha machine, and a small café — and the experience zone is genuinely the better half.
I’ll admit I almost skipped this one. “Beauty store does a character collab” sounded like a pretty low-effort premise, and Seongsu has no shortage of pop-ups competing for a look. But this is being billed as Olive Young’s biggest Sanrio campaign yet, and once I saw the storefront in person — an entire building wrapped in Hello Kitty and Cinnamoroll graphics — curiosity won out.
Where it is and the basics
Location: Olive Young N Seongsu, 13 Yeonmujang 7-gil, Seongdong-gu, Seoul
Dates: August 30 – September 30, 2026
Hours: Daily, 11:00 AM – 9:00 PM
Admission: Free
Entry system: Walk-in only, no reservation app — just line up outside
Parking: Available on-site, but expect it to be tight on weekends given how busy Seongsu already is
I went in expecting a long wait — a collaboration this size, in a neighborhood this popular, on a beauty brand that’s already a magnet for tourists, seemed like a recipe for an hour-plus line. It wasn’t. I showed up on a weekday afternoon, joined a short walk-in queue with no app or reservation involved, and was inside in roughly 10 minutes. If you’re planning around this pop-up and dreading the wait, weekday afternoons are clearly the move.
The entrance signage itself was a small tell about who this pop-up is built for — instructions in four languages before you even step inside. That lined up with what I saw once I was in: on a weekday, I’d guess somewhere around 80% of the visitors around me were speaking English, Japanese, or Chinese rather than Korean. If you’re a tourist worried about a pop-up like this being an awkward, all-local crowd experience, this isn’t that. Olive Young is already a well-known K-beauty shopping stop for foreign visitors, and pairing it with a globally recognized character IP like Sanrio makes it one of the more visitor-friendly pop-ups running in Seongsu right now.
The MD zone: K-beauty’s biggest names, wearing Sanrio
The pop-up is really two experiences stacked into one building. The first is what Olive Young calls the “MD zone” — essentially the store’s regular retail floor, restocked with Sanrio-themed products from the brands Olive Young already sells.
Even on a weekday afternoon, this section was genuinely crowded — noticeably more so than the experience zone on the other side of the store. It’s worth knowing going in that this is still a working retail floor, not a purpose-built pop-up space, so the aisles are the same width they’d normally be. If you’re hoping for open photo-friendly space, the MD zone isn’t really where you’ll find it.
What did impress me was the brand lineup. This isn’t a case of a character sticker slapped on filler product — the collab pulls in brands that are already best-sellers on their own, like Anua’s PDRN cream and Torriden’s Dive-In line, repackaged with Sanrio characters for a limited run. Official coverage puts the collab at 321 products across 81 participating brands, which tracks with how far the theming had spread by the time I made it past the skincare wall.
The most unexpected crossover was in the snack aisle — Nongshim’s Kkokkalcorn corn chips in Hello Kitty packaging, sitting in a beauty store. It’s a small detail, but it says a lot about how far Sanrio’s brand licensing reach goes here: this collaboration isn’t limited to skincare and makeup. I also spotted Dong-A Pharmaceutical’s Garglin mouthwash spray in a matching Hello Kitty box nearby — a pharmacy-shelf item, in Sanrio packaging, inside a cosmetics store. If you needed a single image of how far a character license can stretch across categories, this pop-up is it.
The experience zone: this is where it’s actually worth the trip
If the MD zone is essentially themed shopping, the separate experience zone next door is where the pop-up earns its reputation. This part isn’t for sale — it’s a dedicated space built around a “City Log” concept, split into named sections like Music Square, Neon Street, and Record Plaza.
This was the part of the pop-up that made the whole visit worth it. Life-size speaker props, a giant record display, and pixel-art city graphics fill a set that’s genuinely more ambitious than most retail collab pop-ups bother with — the kind of production value I associate more with Seongsu’s dedicated experiential pop-ups than with a cosmetics chain’s seasonal campaign.
There’s even a small interactive racing-game setup built into the floor — not just a static photo backdrop, but something you can actually play with. It’s a nice touch that keeps people lingering rather than snapping one photo and moving on.
The most popular corner by far was the gacha (capsule toy) station, handing out randomized Hello Kitty keyrings themed around different Korean regions — Seoul, Busan, and others among the twelve city-specific designs created for this campaign. It’s a nice collector’s hook if you’re the type who likes tracking down region-exclusive merch. One thing to flag: getting in the door only took 10 minutes, but claiming your gacha prize meant a second, separate line at this station — budget a little extra time here if it looks busy when you arrive.
After looping through both zones, there’s a small café called CafestaNd tucked into a corner of the experience zone, selling coffee, tea, and Hello Kitty-shaped cake pops at pop-up-friendly prices. It’s a small but well-placed detail — somewhere to sit for a minute before heading back out into Seongsu.
Is it worth the trip?
Honestly, yes — but manage your expectations about which half you’re going for. The MD zone is worth a walk-through if you’re already an Anua or Torriden user and want the limited packaging, but it’s still a regular retail floor at the end of the day, just a busier one. The experience zone is the real draw: it’s the most ambitious set design I’ve come across in a Seongsu pop-up in a while, and it doesn’t feel like an afterthought bolted onto a shopping campaign.
Given how central Seongsu Station is, this is an easy add to a broader Seongsu-dong shop-hopping route if you’re already exploring the neighborhood’s cafes and other pop-ups. Just go on a weekday if you can — the retail side gets genuinely crowded, and a shorter line means more time to actually enjoy the experience zone instead of standing in one.
FAQ
Q: Do I need to make a reservation to visit the Olive Young x Sanrio pop-up?
A: No. It’s walk-in only — just line up outside the entrance. No app or advance booking is required.
Q: How long is the wait?
A: It varies, but on a weekday afternoon I waited about 10 minutes. Expect longer on weekends given how popular both Olive Young and Sanrio collabs are with visitors.
Q: Is there an entrance fee?
A: No, it’s completely free to enter.
Q: When does the pop-up close?
A: The current “City Log” campaign runs through September 30, 2026. As with most Seongsu pop-ups, individual in-store zones can occasionally wrap up earlier than the headline campaign date, so it’s worth double-checking closer to your visit if you’re cutting it close to the end of the month.
Q: Is this pop-up tourist-friendly if I don’t speak Korean?
A: Yes — entrance signage is posted in Korean, English, Chinese, and Japanese, and on my visit the large majority of visitors around me appeared to be international tourists rather than locals.
Bottom Line
If you’re building a Seongsu itinerary for late August or September 2026, this is worth the stop — not for the beauty aisles specifically, but for the experience zone, which is more elaborately built out than most collab pop-ups this size bother with. Go on a weekday, budget about 10-20 minutes for entry plus a little more if the gacha line is backed up, and treat the MD zone as a bonus rather than the main event.
