Korea's Box Office Cools 2.7% as the Chart Tightens (Week 27)

South Korea’s weekly box office contracted in the last full week of June 2026, with total ticket revenue down 2.7% even as four new releases pushed into the top ten. The pullback came alongside a tightening at the summit: the three best-selling titles captured 74.0% of turnover, up from 70.6% a week earlier, according to figures from the Korean Film Council’s integrated ticketing network (KOBIS).

A Thinner Week Overall

The headline number was modest but negative. No film climbed the chart week-over-week, while two slipped, leaving the ranking to be reshaped almost entirely by fresh entries rather than by holdovers gaining ground.

Toy Story 5 stayed at number one, drawing 601,165 admissions for ₩6.07 billion and lifting its running total to roughly 2.22 million viewers. Close behind, the Korean release Nundongja took second with 537,468 admissions and ₩5.47 billion, its cumulative audience still under 843,000 — a sign the title is early in its run and leaning heavily on this week’s business.

Together those two accounted for the bulk of the market’s activity, and the gap back to third place was steep.

A Long-Runner Anchors Third

The clearest outlier sat at number three. Gunche earned ₩1.30 billion from 128,289 admissions, yet its cumulative audience had already reached about 5.84 million — by far the largest running total in the top ten and several times that of the two films above it. It is a mature release still generating meaningful weekly turnover long after opening, and it does much of the work holding the top three’s combined share high.

Four Debuts, Uneven Starts

Four titles entered the chart for the first time, and their opening weeks diverged sharply.

• Marty Supreme (#5): ₩720 million from 69,066 admissions.
• Doraemon the Movie: Nobita’s Undersea Secret Castle (#6): ₩353 million from 39,155 admissions.
• Greenland 2: Migration (#8): ₩335 million from 35,155 admissions.
• Assassination Classroom the Movie: Everyone’s Time (#10): ₩183 million from 17,220 admissions.

A quirk worth noting: Marty Supreme actually out-grossed the fourth-place Wild Thing (₩665 million on 69,575 admissions) despite ranking below it, because the weekly order tracks admissions rather than revenue. On a per-ticket basis, Marty Supreme averaged about ₩10,400 against roughly ₩9,600 for Wild Thing — a premium that let it convert slightly fewer seats into more money.

The two animation debuts, by contrast, opened softly. Neither the Doraemon nor the Assassination Classroom feature cleared 40,000 admissions in its first week, and both landed in the lower half of the chart with cumulative totals essentially equal to their opening tallies.

Reading the Concentration Shift

The most telling structural change was the rise in top-three concentration to 74.0% from 70.6%, a gain of about 3.4 percentage points. With overall revenue down and no title advancing, the market did not broaden — it narrowed, funneling a larger slice of spending toward Toy Story 5, Nundongja, and the durable Gunche.

That combination — falling total sales, a stack of low-opening debuts, and a heavier tilt toward the leaders — points to a soft mid-summer week in which the wide release schedule added titles without adding much demand. Whether the incoming animation slate and Marty Supreme build on their openings or fade will determine if the next reading reverses the decline or extends it.
