150 of 421 Korean titles never charted in Korea

Of the 421 Korean titles that have reached a Netflix Top 10 somewhere in Southeast Asia since 2021, 150 have never once appeared on Netflix’s Top 10 in Korea.

That is 35% of the panel, and it is not a rounding of the tail. It is a structurally different group.

A title that plays at home reaches more than twice as many Southeast Asian markets and is three and a half times as likely to reach number one in one of them.

The relationship is real but loose

Weeks on Korea’s chart and markets reached in Southeast Asia correlate at r = 0.51 across the 397. That is strong enough to be the main story and weak enough that the exceptions are the interesting part.

Read down the right-hand column and the ladder is clean. Read the ends and it breaks: 15 titles reached all six Southeast Asian markets without ever charting in Korea, and 84 of the 134 single-market titles never charted at home either.

Put the other way: 8.1% of the titles that swept the region skipped the Korean chart entirely, and 62.7% of the single-market titles did.

What the exceptions are

The titles that travel without charting at home are mostly broadcast dramas. Young Lady and Gentleman and The Penthouse: War in Life each held eleven weeks across all six Southeast Asian markets; neither appears on Korea’s Netflix chart at all. Dr. Romantic and Sell Your Haunted House are the same shape.

This is not a mystery, and it is the reason we will not call these titles unpopular in Korea. They aired on Korean television. A KBS or SBS drama at nine in the evening is watched on the broadcaster, not on Netflix, so it never competes for a Netflix chart slot at home — while abroad, Netflix is the only place it exists.

The reverse case is smaller and more surprising: titles that hold Korea’s chart for weeks and reach exactly one Southeast Asian market. Guardian: The Lonely and Great God charted fourteen weeks in Korea and one market abroad. Nocturnal held thirteen at home and two weeks in one market.

Films skip home more than series do

52.3% of the films in this panel never charted in Korea, against 24.2% of the series. A Korean film often has its domestic life in cinemas, arrives on Netflix months later, and by then the domestic audience has seen it — while for a Southeast Asian viewer the Netflix release is the release.

That is a distribution fact, not a taste fact, and it is why a chart comparison across countries is harder to read than it looks.

Why this matters for anyone using the numbers

Netflix’s Korean chart is not a smaller version of its regional charts. It is a different chart, because it competes with a domestic television industry the other markets do not have.

Anyone using Korean Netflix performance as a proxy for how a title did in Korea will be wrong in a predictable direction: they will undercount broadcast drama and overcount Netflix originals. We use it here for exactly one purpose — as a second signal on whether a title with an ambiguous name is the Korean work — and even for that we treat absence as a reason to look, never as an answer.

And 140 is a floor, not a count of failures. It includes every title released before July 2021, which had its domestic run before this data starts. We cannot separate those out, so the honest reading of the 35% is: at most that many skipped Korea’s chart, and some of them never had the chance.

What changed on 3 September 2026

One of our source files had gone stale. The Korea-signal table was still the 8 August build, which means it still counted Dangerous Liaisons — the 2022 French film we removed on 25 August after confirming against Wikidata that no Korean work carries that name. Rebuilding it moved the panel from 397 titles to 420, because the newer build also picks up titles that charted after 8 August.

The figures above were all recounted. The ones that moved: 140 titles that never charted in Korea became 150, the share went from 35.3% to 35.7%, and the film-versus-series gap went from 51.9% against 24.1% to 52.3% against 24.2%.

The finding did not change. About a third of what travels never charts at home, and the never-charted titles are still a different kind of title rather than a smaller version of the same one. We are printing the old and new figures side by side because a number that moves without saying so is a number no one should trust.

What changed on 3 September 2026

We added the chart week of 23 August 2026. One title entered the panel with it, and it had charted in Korea, so the denominator grew and the never-charted count did not.

The finding did not change and the headline count did not move: 150 titles travelled without ever charting at home. The share is 35.6% of 421 rather than 35.7% of 420, which is the same third.
