Plush toys first, then the cinemas: how a mascot took 44.7% of Korea's box office

Chiikawa: The Movie: The Secret of the Mermaid Island took 44.7% of South Korea's weekend ticket revenue on October 23-25, its fourth weekend in cinemas, and stayed at number one. ^[1]

The film earned $2.5 million from 320,293 admissions on 1,115 screens, according to Variety's report on figures from KOBIS, the tracking service run by the Korean Film Council. ^[1] Since it opened on September 30, it has gathered $17.5 million and 2,248,137 admissions. ^[1]

That is a large number for a film about a small creature. My reading is that the cinema result is the late arrival of a fandom that was already queuing in the street. It tells us less about a sudden conversion of Korean audiences than about how a character can build a following one shop, one phone case and one shared sense of tiredness at a time, until a film is almost an afterthought.

A film that arrived after the crowd

Chiikawa is a Japanese manga series by the illustrator Nagano. It was serialized on X from 2020, and short animated clips began airing on Japanese television in 2022. ^[2] The film, directed by Kei Oikawa and adapted from the manga, follows Chiikawa and friends to a coastal island where they uncover a local mystery. ^[1]

The Korean story starts earlier than the film. The Korea Herald reported that Chiikawa opened its first Korean store in February 2026 at Yongsan Station in Seoul. Fans in their 20s and 30s waited for hours to buy plush toys, key rings, phone cases and stationery. ^[2]

The queues did not fade. A Record China article, machine-translated from Japanese and summarizing a Newsis report, said numbered queue tickets for a Chiikawa store reached 899 before opening for a Halloween merchandise release on October 7, with an estimated wait of seven hours. ^[3] That was a week after the film opened.

Set the two facts side by side. A shop that makes people wait seven hours for limited stock has already done the hardest job in marketing, which is to make the product feel scarce and the visit feel like an event. Then a film shows up and offers the same crowd a two-hour place to be together.

The design does the work the plot does not have to

The characters are drawn very simply. That is a strength. A face with two dots for eyes asks the viewer to supply the feeling, and a body that small can be stitched onto a key ring, a raincoat or a baseball team's merchandise without losing anything.

The Korea Herald notes the collaborations that have already happened. They include the clothing brands SPAO and Wacky Willy, the rainwear brand W.P.C. and the LG Twins baseball team. ^[2] Record China's summary mentions the Twins and SPAO as well. ^[3] A character that fits on a jersey and a rain jacket is a character that is seen daily by people who never opened the manga.

But the cute surface is not the whole attraction.

The Korea Herald says the sunny-looking animation contains darker material and everyday struggles, including earning money and finding a home. ^[2] The pop-culture critic Ha Jae-keun told the paper the characters are relatable as well as adorable. ^[2] Lee Hong-joo, a professor at Sookmyung Women's University, described them as a cultural code that comforts some adults in their 20s and 30s. ^[2]

Fans quoted in the Newsis-based summary say much the same. They find the characters relatable because they struggle through work and daily life, and some say the characters overlap with themselves. ^[3]

These are interpretations, from two experts and a handful of fans, not a survey of why 2.2 million people bought tickets. But they point the same way, and they explain something the box office alone cannot. A cheerful plush toy that is also quietly anxious is a more honest companion for an adult than a mascot that is only cheerful.

The loop that keeps it running

The business logic is a loop. Merchandise builds a daily presence. The presence builds a crowd. The crowd fills a store, then a cinema. The cinema result is news, and the news sells more merchandise.

The scale of the weekend figure shows how well the loop works. A 44.7% share of revenue means the film took nearly as much as every other title in the country combined. Dividing $2.5 million by that share puts the whole weekend market at roughly $5.6 million. Spread over its 1,115 screens, the film averaged about 287 admissions per screen across three days. Those are my calculations from the reported figures, not numbers in the source.

The film has also kept the top spot into its fourth weekend. Films that depend on opening-weekend curiosity tend to sag by then. Staying at the top suggests a crowd that came back, or came in waves, as people who had waited in lines told friends who had not.

What this says about how fandom travels

The usual idea of an anime hit is a big production with an ad budget that lands on every screen at once. Chiikawa suggests another route. It starts as a free serial on social media, adds short television clips, and turns into physical things people can hold. Only then does it become a feature film. The cost of entry for the fan is low at every step, and each step ties them closer.

The film itself, as Variety describes it, is a mystery on an island. ^[1] Nothing reported suggests the plot is what draws the crowd. The draw looks to be the company of characters people already know.

This is not a cultural takeover. A box-office share measures one weekend, and it moves with whatever else is in cinemas. The cinema result also cannot tell us what brought any individual viewer in. The fandom documented here is concentrated among adults in their 20s and 30s, in a few stores and a few brand partnerships, and nobody has measured its reach beyond that.

What the evidence does show is something more interesting than a takeover. It shows a small, deliberately plain character working as a shared emotional shorthand across a border, with a translation problem of almost zero.

What to watch

The fifth weekend will show whether the audience is a wave that is breaking or a tide. Watch the admissions count and the screen count, and whether the share of revenue stays near 44.7%. Also worth watching is whether the Korean distributor or the Japanese rights holders say anything about who is buying the tickets. If the crowd is the same one that queued at Yongsan, the film is a victory lap. If it is a new one, the loop has widened.
