28. One September, Two Stages — Seoul's Fireworks Are Confirmed for the 5th, and the Museum Costume Play Goes to Its Final

September 3, 2026 | Festival | hellokr.kr

Two events we covered earlier this year have both come into focus, and they have done it in the same month. When we wrote about the Seoul International Fireworks Festival in July, the 2026 date existed only in city administrative documents. It is now official: Saturday, September 5, at Yeouido Hangang Park — the earliest date in the festival's history, pulled about a month forward from its traditional early-October slot. And the National Museum of Korea's costume play, which went nationwide this year, has published its numbers: 275 teams applied, more than three times last year's field, and the road to the September 19 final in Seoul starts this weekend.

This article is the update. It covers what has been confirmed and what is new since the original guides — the fireworks timetable, the traffic controls, the costume play field — and the one scheduling collision worth knowing about: both events open on the same Saturday.

Quick Info

  • Fireworks festival: Saturday, September 5, 2026, Yeouido Hangang Park, Seoul. Confirmed by Hanwha, the organizer
  • Fireworks day: Side programs from 1:00 PM; the fireworks show runs 8:00 to about 9:10 PM. Theme: “Your Infinite Colors”

  • The collision: September 5 has both the Seoul fireworks and the first regional round in Chuncheon
  • Getting to Yeouido: Yeouinaru Station, Line 5 — but read our original guide before relying on it, especially for the way out
  • Getting to the museum: Ichon Station, Line 4 or Gyeongui-Jungang Line, Exit 2, then about 150 m
28 Seoul Fireworks and Costume Play Update

In One Line

September 2026 stacks two of the year's best free events into three weekends — a confirmed fireworks night over the Han River on the 5th, a tripled-in-size costume competition touring four cities, and a final at the National Museum on the 19th.

The Fireworks: What Is Now Official

When our original guide went out, the organizer's site said only that the festival would return to Yeouido in 2026, and September 5 was a working assumption drawn from city paperwork. Hanwha has since confirmed it: the Seoul International Fireworks Festival 2026 takes place on Saturday, September 5, at Yeouido Hangang Park. The company said the date was set with the Chuseok holiday period and international visitor patterns in mind — the same reasoning that moved the 2025 edition to late September. What was a cautious footnote in July is now a fact of the calendar: this is the earliest the festival has ever been held, roughly three weeks ahead of even last year's date and a full month before the traditional first Saturday of October.

The details have followed. This year's theme is “Your Infinite Colors.” Festival-day programming at the park runs from 1:00 PM to 10:00 PM, with the fireworks show itself from 8:00 PM to about 9:10 PM. Seoul's official notice lists three teams: one from the United Kingdom and one from the United States, firing fifteen minutes each, and Korea's Hanwha team with the longest slot of the night at thirty minutes. There is also a pre-festival day on Friday, September 4, with citizen participation programs at the park.

If you cannot be on the riverbank, the show is streamed live on Hanwha TV's YouTube channel — a genuinely useful fallback in a month when the weather can still behave like summer.

One change to the free-for-everyone rule

The festival remains free, unticketed and unreserved on both main banks. But the official site lists something new for 2026: Nodeul Island, the mid-river island we described in the original guide as a calmer picnic-style alternative, operates this year as a reserved, ticketed viewing zone booked in advance through the festival's ticketing page. If Nodeul was your plan, check the official site before counting on walking in.

The traffic controls are published

Seoul has released the control plan, and it is on the same pattern our original guide described. The headline items: Yeouidong-ro closes fully from 3:00 PM to midnight on the day; the Wonhyo Bridge closes from 9:00 AM on the 5th until 3:00 AM the next morning; Yeouinaru Station is again flagged for possible closure during the 7:00 to 10:00 PM crush; and Lines 5 and 9 run 18 and 65 extra trips respectively, with around 6,800 safety personnel deployed. In other words: everything we wrote about arriving early, not driving, and picking your exit station before you sit down still applies, and the original guide has the full where-to-sit and how-to-leave playbook. We will not repeat it here.

The Costume Play: Three Times the Field

The other September story is quieter but, in its own way, more remarkable. The National Museum of Korea's costume competition — where people dress as artifacts from the national collections — drew 83 teams last year as a Seoul event. This year, its first as a nationwide competition, it drew 275 teams and 643 people, more than triple the field. The museum selected 50 entries to advance to the regional rounds.

Those rounds run across four weekends and four cities, each hosted by a national museum: Chuncheon on September 5, Gongju on September 6, Daegu on September 12, and Jeonju on September 13. The winners go to the final on Saturday, September 19, on the Open Plaza of the National Museum of Korea in Seoul. All of it is free to attend.

For a visitor, the regional rounds are a curiosity with a bonus attached: each is staged at a regional national museum whose own collection supplied the source material, so the costumes on stage and the originals in the galleries are a few minutes' walk apart. The final in Seoul is the main event, and our original article covers what the day looks like, how the prizes work, and the one thing that matters most — last year's final capped its audience at 2,000 pre-registered viewers, so check the museum's event page for the 2026 viewing arrangements before you plan a trip around it.

What It Means for Visitors

If you are in Seoul on September 5, you have a choice to make. The fireworks and the first costume play regional round land on the same Saturday — one in Yeouido, one in Chuncheon, about an hour and a quarter apart by train. On paper you could do the Chuncheon round by day and race back for the fireworks by night, but the arithmetic is against you: the good ground at Yeouido is claimed by mid-afternoon, and arriving in the evening means watching from far out. Realistically, pick one. The fireworks happen once a year on one night; the costume play has three more regional rounds and a final still to come. If you can only be in the country that weekend, take the fireworks.

If your trip falls later in September, you are not too late. The Daegu and Jeonju rounds on the 12th and 13th pair naturally with trips to two of Korea's better travel cities, and the September 19 final puts you at the country's largest museum on a Saturday, when it stays open until 9:00 PM and the permanent galleries are free.

And if you miss all of it from home, the fireworks stream live on Hanwha TV's YouTube channel, which is not the same as standing on the riverbank but costs nothing and involves no crowd control whatsoever.

Timeline

The Bottom Line

Both of the stories we flagged earlier this year resolved in the best possible direction: the fireworks date held, and the costume play's national experiment worked before a single regional round was staged — the entry numbers alone settled that. If you are anywhere near Seoul in the first three weekends of September 2026, one of these events is within reach, and neither costs a thing beyond the train fare.

Both are also annual fixtures, so this is not a now-or-never month. The fireworks festival has run every year since 2000, and the museum has built the costume play up year on year rather than winding it down — but note that the fireworks date is no longer a safe assumption in either direction. It has now moved twice in two years, from early October to late September to early September. Whatever year you are reading this, check the organizers' pages first, and our two original guides will do the rest.
