If you thought the cinema crowd was saving its pennies for gritty thrillers or big Hollywood action flicks, think again. The Japanese animated sensation has completely flattened the competition in South Korea. We are talking about *Chiikawa the Movie: The Secret of the Mermaid Island*, and it is running absolute rings around every other film on the marquee.
According to numbers tracked by KOBIS, the data service run by the Korean Film Council, this tiny superstar gripped the box office over the weekend of October 16 to 18. Not just scraped past the finish line, either. It locked down more than 42 percent of all nationwide ticket sales. And get this: that was in its third weekend in cinemas. When most films start running out of steam, Chiikawa is picking up speed.
What happened at the South Korean box office
Let's break down the sheer scale of this weekend takeover. Grabbing 42 percent of a nation's cinema revenue is the kind of dominance superhero franchises used to dream about. Chiikawa did it with a story about a squeaky little round character exploring a mysterious island.
Variety reported the KOBIS figures, showing that the Toho-distributed hit left rival titles eating dust across South Korea. Other releases, including local dramas and imported action titles like Whalefall and Street Fighter, could not get close. Moviegoers voted with their wallets, and they voted for sheer cuteness.
In cinema terms, week three is usually when a film drops off by half. Word of mouth either saves you or sinks you. For Chiikawa, that word of mouth clearly turned into a full-blown roar. The film didn't just hold its ground; it tightened its stranglehold on South Korean multiplexes.
Why is Chiikawa such a monster hit
If you have spent any time online over the past two years, you have seen this face. Chiikawa, short for "Nanka Chiisakute Kawaii Yatsu" (something small and cute), began life as an online manga drawn by illustrator Nagano. It follows a timid white creature navigating a strangely tough world, doing odd jobs, failing exams, and crying a lot.
That mix of cuteness and genuine dread struck a massive chord across Asia. Adults love it just as much as kids do. Maybe even more. The merchandise sells out in minutes in Tokyo, Seoul, and Taipei. People queue around city blocks in the freezing cold just to buy plush keychains.
Taking that craze to the big screen with The Secret of the Mermaid Island was always going to draw crowds. But taking nearly half the country's box office revenue three weeks into release? That is a whole different level of pop culture madness. South Korean fans clearly turned theatrical screenings into community events.
How competitors fell behind Chiikawa
South Korea's cinema calendar is notoriously tough. Local films usually put up a fierce fight on home turf. Add in action titles and Hollywood imports, and the box office is usually a messy brawl.
Not this time. The KOBIS data shows the competition barely laid a glove on the Toho release. While other titles scraped together small shares of the weekend gross, Chiikawa sucked all the oxygen out of the room.
Cinemas know where their bread is buttered. When a film commands over 42 percent of total takings in its third week, theatre managers start bumping other screenings off the schedule to add more Chiikawa showtimes. It creates a snowball effect: more screens mean more tickets, and more tickets keep the film planted firmly at number one.
What fans are saying about the film
Go on social media and you will see South Korean theatregoers showing off their popcorn buckets, photo cards, and cinema freebies. Collecting exclusive cinema merch has become a sport for this fandom. People aren't just going once; they are buying repeat tickets to collect different theatre gifts.
Fans love the movie because it balances pure sweetness with that weird, slightly spooky undertone the manga is famous for. The Mermaid Island storyline gives the characters real stakes, genuine danger, and plenty of tearful hugs. It hits that sweet spot of comfort and mild peril that audiences cannot get enough of right now.
Plus, seeing those tiny round creatures blown up on a giant cinema screen is pure dopamine. In a world full of grim news, people clearly wanted ninety minutes of pastel-coloured comfort, and they turned up in droves to get it.
What comes next for Chiikawa at the box office
With week three wrapped up in dominant fashion, the big question is how long this box office reign can run. Toho has a bona fide juggernaut on its hands, and South Korea has proven to be one of the title's absolute happiest hunting grounds.
New releases will try their luck in the coming weeks, but breaking a 42 percent market share takes serious firepower. Unless a massive domestic blockbuster or a giant Hollywood release lands with an almighty bang, Chiikawa looks comfortable at the top of the pile.
One thing is for certain: cute culture is serious business. If anyone ever tries to tell you that sweet, animated mascots are just for toddler morning TV, point them toward the Korean box office receipts. Chiikawa just schooled the entire movie industry.
