Korea's Convenience Store Universe: How the Big Four Brands Were Built — and What Koreans in Their 20s and 30s Actually Buy There

Spend a few days in Seoul and you’ll notice it fast: two or three convenience stores per block, each one doubling as a diner, a post office, and a cosmetics counter. As of late 2025, the four major brands operate roughly 53,000 stores. Crunch the numbers against the population and you get one store for every 960 people. That density has shaped an entire culture — one where the convenience store isn’t just a store, but a way of life.

Where did Korean convenience stores come from?

The date that matters is May 6, 1989. That’s when the 7-Eleven Olympic Branch opened its doors in Oryun-dong, Songpa-gu — in the shopping arcade of the Olympic Athletes and Journalists’ Village, a Seoul apartment complex built after the ‘88 Games. Korea Seven had signed a technical licensing deal the year before with Southland Corporation, 7-Eleven’s American parent. At a time when most blocks still relied on a neighborhood super — a tiny, family-run grocery — a store that stayed lit 24 hours and sold everything at a fixed marked price was a genuine curiosity.

The following year, 1990, two brands jumped in within months of each other. In October, FamilyMart opened its Garak-siyoung Branch in Garak-dong, Songpa-gu. In December, LG25 opened its Kyunghee Branch in Hoegi-dong, Dongdaemun-gu. Those two names are today’s CU and GS25 — only the signs have changed. LG25 became GS25 in 2005 when GS Group split from LG. FamilyMart rebranded to CU in June 2012, borrowing the idea of “CVS for You” and quietly severing its remaining ties with Japan’s FamilyMart chain.

The last to arrive was Shinsegae. In late 2013, E-Mart’s board approved the acquisition of With Me, a homegrown chain of 80–90 stores at the time. In July 2017, the brand was relaunched as E-Mart24.

🏪 A Timeline of Korea's Big Four Convenience Store Brands

In 2022, Korea Seven acquired the last remaining Japanese-owned chain, Ministop — roughly 2,600 stores nationwide — for 313.3 billion won. That closed the book on Japanese brands in Korean convenience retail. The domestic Big Four now command the entire field.

That third stat card deserves a pause. In 2025, the total store count dropped by 1,586 — the first annual contraction since the convenience-store format arrived in 1988. The era of headlong expansion is over. The fight now is about what you sell inside each box and how much you sell of it. Everything that follows — the frantic shelf rotation, the new-product churn — flows from that shift.

Why does everything feel different every time you walk in?

Ask any first-time visitor to a Korean convenience store what strikes them, and this is the answer: the thing they bought last month is gone. The reason is simple. The core customer is someone in their 20s or 30s, and the trend cycles of that demographic play out directly on the shelves.

The liquor aisle tells the story in a single frame. At CU, highball sales grew 553.7% in 2023, then 315.2% in 2024, then 190.1% in 2025. At GS25, highballs surged 376.7% in 2024. As a share of CU’s combined wine, spirits, and highball sales, highballs jumped from 8.3% in 2022 to 36.3% in 2023, reaching 38.6% by January 2024. Yet as of mid-2026, the center of gravity has already shifted to an entirely different drink.

Desserts, collaboration merch — they all move at this same velocity. This is why any list that names specific “must-buy” products is largely obsolete within six months. What follows is a map built on categories, not products — a framework that holds steady even as individual items come and go.

What Koreans in their 20s and 30s actually buy — seven categories

1. Ready-to-eat meals — the engine of growth

This is the most convincing growth story in the store. At CU, instant-food sales growth accelerated year by year: 13% in 2024, 21.8% in 2025, and 24.5% for January–May 2026. GS25 posted 23.9% in 2025 and 19.2% for January–May 2026. 7-Eleven saw 20% in 2025 and 16% for the same period in 2026. A lunchbox runs 4,000 to 6,000 won — and as restaurant prices have climbed, it’s graduated from “a cheap meal” to “a smart meal.”

The competitive battleground has shifted from price to taste. All three major chains have overhauled their flagship meal lines with quality as the selling point, and they’re expanding in-store cooking — fried chicken, pizza, fresh bakery — at a rapid clip. convenience-store food no longer carries the faint whiff of defeat it once did.

2. Drinks and coffee — the reason people stop in twice a day

The number-one reason Koreans in their 20s and 30s walk through the door is a drink. The ritual is ingrained: buy a cup of ice, pour an RTD coffee over it — the lowest-cost version of an iced americano, essentially a Korean invention at this point. In-house brewed coffee lines (7-Café, Café25, and the like) and zero-calorie sodas keep expanding. This category runs on habit more than hype, so the shelf layout is the most stable in the store.

3. Alcohol — from getting drunk to drinking well

The highball and single-malt story we traced earlier is the headline here. The convenience-store liquor aisle has been quietly redefined: it’s no longer about “cheap alcohol to get the job done” but about “something interesting to drink.” Wine, low-ABV liqueurs, and non-alcoholic beer have all carved out permanent shelf space. Non-alcoholic options, in particular, are getting dedicated zones in a growing number of stores.

4. Desserts and snacks — the fastest shelf in the building

This is the highest-turnover real estate in any Korean convenience store. A collaboration dessert hyped on TV or social media can sell out 20,000 pre-ordered units in 20 minutes — and that’s not unusual. Recommending a specific product in this category is essentially futile. The correct answer is always: whatever is stacked in bulk at the front of the shelf right now.

5. Beauty — from grab-and-go to destination

There’s even a nickname for it now: pyeon-beauty (pyeon as in pyeonuijeom, convenience store). At CU, cosmetics sales grew 28.3% in 2023, 16.5% in 2024, and 21.4% for January–November 2025 — and roughly 70% of that revenue comes from shoppers aged 10 to 29. 7-Eleven entered the category in earnest in the second half of 2025 and saw beauty sales jump 30% year-on-year from January 1 to June 21, 2026. The engines are low-cost color cosmetics — lip tints in the 3,000–5,000 won range — and travel-sized skincare. In the same period, 7-Eleven’s beauty sales to foreign shoppers rose 71%. For travelers, this aisle is already part of the shopping circuit.

6. Merch and K-pop albums — the convenience store as comeback stage

The newest category of the seven. GS25 started selling K-pop albums in 2023. By January–July 2026, cumulative sales from idol albums and collaboration merchandise had multiplied 100x compared to the full year of 2023. The model is straightforward: release an album timed to a comeback, bundle it with exclusive collaboration items. Here’s the fascinating part: in the first half of 2026, more than 70% of idol album purchases at GS25 were made with foreign-issued cards.

7. Household goods and lifestyle services — the store beyond the shelves

Over-the-counter medicine, disposable goods, umbrellas, charging cables — plus parcel delivery, ATMs, and ticket kiosks — are pulling in customers of all ages. The habit of checking stock on a convenience-store app and reserving items for pickup has also taken hold. At this point, a Korean convenience store is less a shop and more a piece of urban infrastructure, captured in the coinage pyeonsegwon — a play on the real-estate term yeoksegwon (station catchment area), meaning a neighborhood whose quality of life is defined by a convenience store within a two-minute walk.

If it's so expensive, why do people keep going?

Koreans themselves don’t think convenience stores are cheap. In a 2026 survey by OpenSurvey, 76.6% of shoppers — three out of four — said they found convenience-store prices expensive. Yet in the same survey, 84.1% said they would miss convenience stores or found them impossible to fully replace.

The numbers reveal a consumption pattern quietly reshaping itself. The usage rate slipped from 88.8% in 2022 to 83.1% in 2026, and monthly visits dropped from 10.7 to 8.5. But average spend per visit has climbed every year. Koreans are going less often and spending more per trip. That shift has made bundle promotions — 1+1, 2+1 — the center of gravity, and checking the store app for deals before heading out is now second nature.

What does this mean for travelers?

Korean convenience stores are already woven into the tourist itinerary. In the first half of 2026, foreign-card sales at GS25 rose 60.2% year-on-year. CU saw overseas payment amounts jump 65.7% for January–May. In July, roughly 100 stores in coastal tourist destinations — Gangneung, Sokcho, Haeundae, Jeju — recorded a 136.9% surge in foreign-customer sales. The top items: bottled water and drinks, followed by instant noodles, milk, and snacks. The top locations by foreign-card spend: Myeongdong, then Hongdae, then Jeju.

GS25 has rolled out K-Station, a foreigner-focused store format featuring Hangang-style instant ramen cookers, popular drinks, and souvenir items. As of late June 2026, 91 stores had been converted, with plans to reach 200 by year-end.
