The anger was not about the film being bad.
Chiikawa the Movie: The Secret of Mermaid Island took ¥6.77 billion and 4.69 million admissions in seventeen days.1 Its Filmarks average is 4.1 out of 5 across more than 35,000 reviews.2 By the numbers, nothing at all is wrong.
And yet in August 2026 the film blew up. What was disputed was not the animation or the script, but what Chiikawa chooses to do near the end. More precisely: whether Chiikawa was allowed to choose it.

Where this article stands
To be clear up front: I have not seen this film in a theater.
So what I am not evaluating is the work itself — its direction, its performances, its construction. What I am looking at is what happened on the audience's side. The materials are creator Nagano's official interview, the critical writing that appeared after release, and the record of the argument.
Major spoilers, including the ending, follow.
The basics first. Released July 24, 2026, 99 minutes. Original work and screenplay by Nagano herself, directed by Kei Oikawa, animation by Cypic, distributed by Toho.3 The source is the arc collected in volume 8, informally the "Siren arc." Eirin rated it G — no age restriction. Its first three days took ¥2.24 billion and 1.5 million admissions across 447 screens nationwide, 65 of them IMAX.4
What happened on August 7
Motoi Karaki posted this to X:
There's apparently a lot of interpretation going around about the Chiikawa movie, but the first thing I thought was "I can't show this to my kid." I'm the kind of parent who thinks children should be exposed to some sex and violence, but this story doesn't work for me. Near the end, Chiikawa weighs the circumstances and gives up on telling the truth. Chiikawa resolves to shoulder a certain amount of cowardice.5
The following posts make the argument's shape clear. Not everything has to be dragged into daylight; in the adult world this happens all the time. But how does a child, still developing, receive that? Might they lose the courage to speak up when they witness wrongdoing? Might it work as an excuse — "well, Chiikawa kept quiet and let it slide too"?
He goes on: of course you shouldn't expect heroics from a small cute creature to begin with, but this is currently one of the country's biggest characters, so to a child's mind that behavior will function as a substantial norm.
The post passed eleven million views. Both attacks and defenses arrived in bulk.
Two kinds of rebuttal stood out. One corrected the reading: Chiikawa's silence is not cowardice but consideration. "This silence isn't to conceal wrongdoing (to shoulder a bit of cowardice) — it's the kindness of covering for someone."5 The other rejected the premise outright. "Chiikawa was never an educational project, so asking that of it is wrong."5 Or: a parent should use that moment to ask the child, what would you do?
What was disputed was norms, not quality
Neither the criticism nor the rebuttals contain much in the way of disparagement of the film.
Karaki's post itself opens by acknowledging that interpretation is going on — that people are reading the work — and only then moves to norms. What he objected to was not that the story fails, but what the story teaches a child.
The other side is not saying the film is too good to criticize. It is saying the film has no obligation to supply norms in the first place.
So the two are not arguing about quality at all. They are arguing about what role this work should be made to carry. The criticism holds that one of the country's biggest characters comes with a responsibility to provide a norm. The rebuttal holds that popularity does not generate that responsibility.
This is not a disagreement about criticism. It is closer to a disagreement about ownership. When a work gets big, whose does it become?
The Doraemon films already made that conversion
Karaki himself reaches for Doraemon as the contrast: he cannot help recalling why the Nobita of the theatrical Doraemon films is written to abandon his baseline laziness and summon courage.
The comparison works harder than he needed it to.
The first theatrical Doraemon, Nobita's Dinosaur, opened in March 1980.6 A new one has arrived every spring since. The dramaturgy is well known. The Nobita of the TV series skips his homework, leans on gadgets, and fails. The Nobita of the films stands his ground at the end without a gadget. The same character carries a different norm depending on the format he appears in.
Then, in March 2008, the Ministry of Foreign Affairs appointed Doraemon as Japan's first "Anime Ambassador."7 The stated reason was that the work depicts contemporary Japanese life and customs, which made it suitable for the role. A fictional character became an instrument of the country's cultural outreach.
At that point Doraemon is no longer merely a work by Fujiko F. Fujio. It is treated as public property, expected to behave as public property, and in fact written that way. Nobita finding his courage in the films reads less like an author's preference than like a response to a requirement that comes with the position.
That, presumably, is what Karaki wanted. Shouldn't Chiikawa have made the same conversion by now?
Nagano's work is not built to hand over norms
The complication is that Chiikawa comes from somewhere else entirely.
It grew out of a serialization on X, and it became popular while keeping its unease and its unfairness intact. There is subjugation work, there is pay, there are things that go unrewarded, and there are changes that do not revert while the cute drawing stays cute. The popularity is not the result of stripping the unease out. If anything, the unease was accepted along with everything else.
The creator's own language sits far from the supply of norms. In the interview on the official site, Nagano explains the mermaids Hitoha and Futaba this way:
In the original roughs, Hitoha and Futaba were characters with faces and lines, but I felt they were talking too much, and I prefer it when there are no lines, so I made them into characters whose faces we can't see and whose words we can't hear.8
Faces and words were taken away, afterward, from the two figures at the center of the story. It was not that they were conceived mute; she let them speak, judged it excessive, and erased it. The route by which a motive gets explained in a character's own voice was closed at the design stage.
On child viewers, she says this:
If children see it, I'd be very happy if they later remember it as "I saw a movie like this once." If it stays somewhere in their heads as a memory and becomes a foundation for making something themselves, I'd be happier still.8
That is not "please understand it now." It is "take it home without understanding it." It sits on the opposite side from didactic clarity.
A work that hands over a norm has to be understood on the spot. This work has not-understanding-on-the-spot built into it.
Past a threshold, a work starts being treated as public property
Even so, "it was never an educational project" does not settle things either.
Whatever the intent, box office and distribution scale create real conditions. 447 screens, summer holidays, a G rating, no age restriction. A work placed in that configuration becomes something families routinely encounter, whether or not the author wanted that. The August 7–9 weekend alone drew 1.147 million people.1
The character of the work does not change; the place it is put changes. And once that place passes a certain scale, society starts assigning roles on its own.
That is what happened to Doraemon. A work that ends up appointed as a national ambassador is no longer handled only as a comic somebody drew because they liked drawing it.
Chiikawa looks like it is mid-stride across that threshold right now. Karaki's anger comes from a reading in which Chiikawa is already on the public-property side; the rebuttals come from a reading in which it is not yet. As descriptions of fact, both are half right. A work standing on the threshold is visible from both sides.
The volume of interpretation is the same thing wearing another face
The other phenomenon of this summer comes from the same place.
Animate Times published a reading of the film's view of life and death,9 Real Sound read the Siren through the frame of beneficial versus harmful animals,10 Filmarks accumulated over 35,000 reviews, and personal blogs and note posts kept coming without limit.
Impressions and interpretation are different acts. An impression can be written after watching. Interpretation gets written when watching was not enough.
When a work hands itself over without fixing its meaning, whoever receives it goes and fixes the meaning themselves. That labor ran once per viewer over three weeks. And because the fixed meaning differs from person to person, "Chiikawa was a coward" and "Chiikawa was kind" come out of the same film.
In What is a cult film I wrote that a work is constituted by when it is watched, where, with whom, and how it is talked about. The structure is similar here, but the speed and scale are nothing alike. A cult film builds its community over years, through midnight screenings and rumor. This film put 4.69 million people through the same labor in three weeks.
The fight over norms happened because that labor ran at volume. If nobody had done the work, there would have been nothing to fight about.
Can it decline?
The question probably rests here.
Does Chiikawa walk the road of the theatrical Doraemon, or decline it?
Walking it means changing the dramaturgy to match the scale — in the films, a little clearer than in the serialization or on TV, a little braver, a little more redeemed. That is not decay. It is what Doraemon has done for forty-five years, and the ministry's appointment sits on top of that accumulation. That many children took something real from it is probably also true.
Declining means not changing the character of the work when the scale changes. Nagano's "if they remember it later" sounds like that side. It takes a form of time that says: you don't have to understand this now, just carry it for a few years.
The same thing I wrote in What remains after Arashi's last concert applies here. More can be read from what a reaction that size exposed than from who was right. What got exposed this time is that the expectation — a cute-looking character ought to supply a norm — is still remarkably strong.
In To preserve film, you have to grow an audience I wrote about attempts to hand children the cinema itself. This summer the same problem arrived from another direction. Growing an audience may not only mean showing them the right norm. It should also mean building up how long they can stand carrying something home unresolved.
And whether a kindergartner can stand that is probably not decided on the work's side.
