What’s Actually Trending in Seoul Right Now: A 2026 Field Guide

I have lived through enough Seoul summers now to notice when the city actually changes shape, not just when a new cafe opens. 2026 is one of those years. Between the Han River, the neighborhoods, the number of tourists on the street, and what people are actually lining up for, the city feels different than it did even two years ago. Here is what is genuinely trending right now, with real numbers behind it, not just vibes.

The Running Boom Has Taken Over the Han River

Running crews now line the Han River every morning and evening, dozens of people in matching gear, and the scale behind that scene is real: the number of marathons held nationwide surged from 19 events in 2020 to 254 in 2024, more than a thirteenfold increase in four years, with over a million total participants (The Korea Herald). It has become popular enough to reshape a category of the sportswear industry, with the running lifestyle economy now described as eclipsing what golf represented a decade ago (Seoulz).

The growth has a real cost, though. Seoul city figures show public complaints tied to marathon road closures climbed from 15 in 2021 to 498 in 2023, with residents, business owners, and even tourists caught off guard by repeated weekend closures around the Han River bridges and central districts. Mayor Oh Se-hoon has said the city is reviewing earlier start times and secured detour routes in response.

Every Neighborhood Has Its Own Gentrification Story Now

Seongsu-dong just cleared a major hurdle for an 81-story residential tower and a 53-story office complex on the former Sampyo concrete-mixing plant site, right at the intersection of Seoul Forest and the Han River, expected to break ground next year (Seoul Economic Daily). It is the clearest sign yet of how far that neighborhood has moved from its industrial roots. As of 2026, the neighborhoods most commonly named as currently gentrifying include Seongsu-dong, Euljiro, Mangwon-dong, Yeonnam-dong, Mullae-dong, Cheongnyangni, Yongsan, Hannam, Ikseon-dong, and Seochon… a genuinely wide spread across the city, not one isolated pocket.

Mangwon-dong is a useful example of the pattern: a traditional market, gradual cafe openings starting around 2015, a 2017 renovation of Mangwon Hangang Park that brought Han River picnickers, and a 2019 market remodel that brought cleaner floors and brighter lighting, each step raising the neighborhood’s profile a little further (Visit Seoul).

Tourists Are Here in Numbers Seoul Has Never Seen

Korea welcomed 10.71 million foreign visitors in the first half of 2026 alone, up 21 percent year over year, with card spending topping 10 trillion won, about three months earlier in the year than it did in 2025 (Korea JoongAng Daily). Seoul specifically saw foreign visitor spending jump 57 percent to a record 5.62 trillion won, led by shopping and medical tourism. The weak won is a direct driver: it makes accommodation, dining, and shopping feel meaningfully cheaper to visitors converting back to dollars or euros, which is part of why South Korea is on track to approach 20 million visitors nationwide this year.

The Shopping Trip Isn’t Duty-Free Anymore

Tourist shopping habits have shifted away from traditional duty-free counters toward the same retail chains Koreans actually use. Musinsa saw a 348 percent jump in foreign customers and a 343 percent jump in their spending in a single year, while Olive Young saw foreign shopper numbers rise 77 percent and spending rise 106 percent, with purchases made by visitors from 189 different nationalities (The Korea Times). The shorthand among tourists now is “Ol-Da-Mu”… Olive Young, Daiso, Musinsa… a three-stop itinerary that barely existed as a tourist concept a few years ago.

Lining Up Is the New Reservation

Seoul’s “Open Run” culture, queuing for hours before a bakery even opens, has become one of the more visible food trends of the year, with some bakeries reporting one to two hour waits during peak periods. The term “bbangjisullae,” or bread pilgrimage, has entered everyday use to describe people traveling across the country, sometimes taking an overnight train, specifically to try a bakery’s exclusive item. On the higher end, Seoul placed six restaurants on Asia’s 50 Best Restaurants 2026 list, up from four the previous year, with Mingles landing at number four and Onjium’s Cho Eun-hee named Asia’s Best Female Chef 2026 for her work modernizing Korean royal court cuisine (The Korea Herald).

The Classroom Is Getting More International Too

This mirrors something I see directly in my own classrooms: Korea’s international student population has grown fast enough that the country hit its “Study Korea 300K” enrollment target ahead of schedule, with official figures putting international students on D-2 and D-4 visas at 314,397 as of February 2026. More foreign students in Seoul specifically means more of the city’s cafes, running crews, and neighborhoods are shaped by people who are here for a semester or a few years, not just visiting for a week, which changes the texture of a trend differently than pure tourism does.
