⚡ Quick Answer
The Chiikawa movie 3rd theater bonus is the "Gokigen Siren♫" pull-back car, distributed starting August 22, 2026 at all screening venues across Japan. There are 3 designs (Chiikawa, Hachiware, and Usagi riding the Siren), distributed randomly, one per person per screening, while supplies last.
What Is the Chiikawa Movie "Gokigen Siren" Pull-Back Car?
The name alone is a lot. "Gokigen" (ごきげん) translates roughly to "in a good mood" or "cheerful" in Japanese, which makes it both adorable and slightly terrifying given who Siren is in the film. The bonus is a miniature pull-back car toy featuring the Siren character as the vehicle body, with one of the three main characters (Chiikawa, Hachiware, or Usagi) riding on its back.
The mechanics are simple: pull the toy backward, let it go, and the Siren zooms forward at full speed. It is a playful, kinetic nod to one of the film's most memorable characters, and frankly a wildly inspired choice for a theater collectible. Most bonus items are stickers or paper goods. A wind-up toy that actually moves? That's a flex.
📊 Key Stat: The Chiikawa movie surpassed 8.07 billion yen (approximately $50.7 million USD) in just 20 days, with over 5.63 million admissions — making it Japan's top-grossing film of 2026 so far.
How Do You Get the 3rd Theater Bonus?
Distribution starts Saturday, August 22, 2026 at all theaters nationwide in Japan currently screening Chiikawa the Movie: The Secret of Mermaid Island. This applies to both the standard version and the IMAX screening — you get the same bonus regardless of which format you watch.

The bonus is handed out at the theater entrance when you walk in for your screening, not at the ticket counter. So do not skip the queue or leave early thinking you can grab it on the way out. You go in, you get your toy.
"Chiikawa is officially becoming a movie. The title is The Secret of Mermaid Island. I hope you look forward to it."
Rules to Know Before You Go
- One per person, per screening. Even if you bought multiple seats in the same showing, you only receive one pull-back car. Bring your friends in person if they want one too.
- Quantities are limited. Each theater has a set number of units. When they run out, they are gone. The earlier in the distribution period you go, the better your odds.
- You cannot choose your design. The three variants are distributed randomly. Chiikawa, Hachiware, or Usagi riding the Siren: the movie decides.
- Do not call the theater to ask about stock. The official guidance specifically requests fans avoid calling to check remaining quantities. Save yourself the awkwardness.
- The 2nd bonus (BonBon Drop Sticker) ends August 21. The switch happens the day before the 3rd bonus starts. If you are going August 22 or later, you will receive the pull-back car, not the sticker sheet.
💡 Pro Tip: Go early in the first week of distribution if you are chasing a specific character. Trading communities on X and Japanese fan boards tend to organize swaps fairly quickly after each bonus wave drops, so even if you pull the wrong character, there's usually a path to your preferred version.
All 3 Gokigen Siren Designs: Which Character Rides Which?
The three variants each feature the Siren character as the base of the pull-back car toy, with a different main character sitting on its back. Each one captures a slightly different personality:
Chiikawa Version
The titular protagonist riding the Siren. Chiikawa's round, wide-eyed expression paired with the Siren's dramatic silhouette is a study in contrasts. The teeny anxious creature on the back of a legendary sea monster is the most on-brand image this franchise has ever produced.
Hachiware Version
Hachiware, the striped cat companion, sits atop the Siren in what fans online are calling the most dramatic-looking of the three. Hachiware's composed, thoughtful personality makes the image feel oddly dignified, which makes it funnier.
Usagi Version
Usagi, the chaotic rabbit of the group, on top of the Siren is the purest form of "two unpredictable forces combining." Fan reaction online to this particular variant has leaned toward screaming in affection. Several Japanese blog posts described it as "terrifying in the best way."
I will say, from someone who has spent a fair amount of time tracking down limited theater collectibles across multiple fandoms: the pull-back mechanism is a masterstroke. Static figures are lovely, but a toy you can actually play with hits differently. When I first saw the announcement image, my immediate thought was "they're going to make people see this movie four times just to complete the set," and honestly, they might be right.
The Full Chiikawa Movie Theater Bonus Timeline
This film has been running a rolling theater bonus program since opening day, which is one major reason it has kept audiences returning week after week. Here is the full picture:
| Bonus Wave | Item | Distribution Period | Variants |
|---|---|---|---|
| 1st Bonus | Charm Mini Figure | From July 24, 2026 (opening day) | 8 types, random |
| 2nd Bonus | BonBon Drop Crystal Sticker Sheet | Until August 21, 2026 | Full cast sticker set per sheet |
| 3rd Bonus | Gokigen Siren Pull-Back Car | From August 22, 2026 | 3 types (Chiikawa / Hachiware / Usagi), random |
The escalating creativity of each bonus wave is not accidental. Toho and the production committee are clearly using the gifts as a tool to sustain box office momentum beyond the opening weekend rush. It is working: the film drew over 4.69 million admissions in just its first 17 days, and the number has only climbed from there.
Why Is Everyone Still Watching the Chiikawa Movie?
A film does not cross the 8 billion yen mark in 20 days on cute characters alone. Opening day alone brought in 990 million yen ($6.05 million), making it the seventh-best opening day in Japanese box office history. That is a number that sits alongside some of the most beloved anime films ever made.
The secret is the Siren Arc itself. Nagano's source material for this film ran on X from March to November 2023 and trended every time a new chapter dropped. It became the longest, most emotionally complex storyline in the series, one that blends horror, humor, and genuine pathos in a way that broader anime audiences tend to underestimate before they experience it firsthand.
"A cartoon that looks like it is for five-year-olds, but feels, once you watch it, like it was made for exhausted twenty-somethings who are just trying to get through the week."
The film adapts the Siren Arc as a full feature-length adventure under the direct supervision of Nagano, who also wrote the screenplay. Director Kei Oikawa, known for episodes of the Chiikawa anime series, keeps the film faithful to the series' tone while expanding the visual scale in ways the weekly TV format never could.
📊 Key Stat: The Chiikawa manga franchise had sold over 3.6 million copies in circulation by November 2024, and the YouTube anime series has accumulated over 400 million views, giving the film a massive built-in global audience.
The bonus strategy is one piece of a larger picture. The film dominated Japanese screens throughout the summer vacation period, running in 447 theaters simultaneously and effectively cornering the family and young adult market while Hollywood's biggest summer releases queued behind it. The rolling gift program gives repeat viewers something new to hunt each time, and it is genuinely clever merchandising.
Frequently Asked Questions
When does the Chiikawa movie 3rd theater bonus distribution start?
Distribution of the 3rd theater bonus, the Gokigen Siren pull-back car, begins on Saturday, August 22, 2026 at all theaters in Japan currently screening the film. It follows directly after the 2nd bonus (BonBon Drop Sticker), which ends on August 21. Supplies are limited, so earlier visits give you a better chance of getting one.
Can I choose which pull-back car design I receive?
No. The three designs (Chiikawa, Hachiware, and Usagi versions) are distributed completely at random. You cannot request a specific variant at the theater. If you want a particular design, your best option is to see the film multiple times or connect with fellow fans online to trade.
How many pull-back cars can one person receive per theater visit?
One per person, per screening. Even if you purchased multiple seats in the same showing, you only receive a single pull-back car. Each person attending the screening must be physically present at the theater entrance to receive their own bonus item.
Does the 3rd bonus apply to IMAX screenings too?
Yes. Whether you watch the standard version or the IMAX version of the film, you receive the same 3rd bonus item. The Gokigen Siren pull-back car is the same regardless of which format you choose, so the decision between standard and IMAX can be made purely on how you want to experience the film.
Where do I pick up the bonus at the theater?
The pull-back car is distributed at the theater entrance when you enter the screening room, not at the ticket counter. It is not available before or after the screening. Arrive with enough time to enter without rushing so you do not miss the handout window.
The Bottom Line
The Gokigen Siren pull-back car is a theater bonus that actually earns a second trip to the theater. Three random variants, a character you can physically play with, and a window of opportunity that starts August 22 and runs only while supplies last. If you are already a Chiikawa fan who saw the film in week one, this is the excuse you did not need but will absolutely use. If you have not seen the film yet, now you have two reasons: the story, and the toy.
For international fans: distribution of the film is rolling out in Southeast Asia and beyond throughout August. Singapore screenings begin August 20 at Golden Village. Keep an eye on local distributor announcements to see whether theater bonus programs will be replicated outside Japan.
