A Korean webtoon is read 14x more once it becomes a drama. Japanese manga, 3.7x

Korean studios keep turning comics into television. The question nobody had put a number on is which side of that trade gets the attention — the comic or the show.

We took every comic that Wikidata records as the source of an adapted work with a Korean connection, kept the 51 pairs where both the comic and the adaptation have an English Wikipedia article, and counted how often each was read over the same 30 days. Human traffic only, same window, both sides.

The adaptation usually wins. How much it wins by depends on where the comic came from

Of the 51 pairs, the adaptation was read more in 37. That much is unsurprising. The split underneath it is not.

A Korean webtoon that gets adapted is typically read fourteen times less than the show made from it. A foreign comic in the same position is read 3.7 times less, and in a third of cases it is read more than the Korean adaptation of it.

The gap is not small at the top

Orange Marmalade is the clearest case: the webtoon was looked up 14 times in a month. Fourteen. The drama made from it was looked up 1,142 times.

Two Korean webtoons out-read their adaptations, and both are small

Neither is a case of a webtoon holding its own against a hit. Both sit under a thousand reads. Yumi’s Cells is the more interesting of the two, because the same webtoon also has a television adaptation — and against that one the webtoon loses 16.8x. The film simply reached fewer people than the comic did.

Where the foreign originals win, they win as themselves

The twelve cases where the source out-read the Korean adaptation are almost entirely Japanese properties that were already famous before any Korean studio touched them.

These readers arrived for the manga. The Korean version is the footnote.

What this says about the two industries

Korean webtoons and Japanese manga are both comic industries, and both feed adaptations. But they hand the adaptation a different starting position.

A Japanese manga brings an audience with it. A Korean webtoon, on the English-reading internet, mostly does not — it acquires one after the drama airs. That is why the median gap is 14x on one side and 3.7x on the other. The full table, comic by comic, is on the webtoon adaptations page.

⚠ This is a measure of looking things up, not of watching or reading them. A webtoon read inside a publisher’s app leaves no Wikipedia trace; a drama on a global streaming service invites one. Part of the 14x is that asymmetry rather than indifference. What the number does show is where the English-language curiosity sits — and it sits on the adaptation. Musical acts run the other way: attention halves two months after the peak, because a comeback spends an audience rather than building one.

Method

Wikidata returned 145 comic-to-adaptation pairs with a Korean connection. 94 were dropped because one side or the other has no English Wikipedia article — dropped, not counted as zero, because “no article” and “nobody read it” are different facts. The remaining 51 were measured over 2026-08-08 to 2026-09-06, English Wikipedia, human traffic only, both sides on the same days. Origin country was queried separately from Wikidata P495; all 51 sources carried one.
