Attack on Titan Day September 9 Officially Registered: New Projects, Anime Film, and Free Manga Details Explained

I honestly thought we were done getting huge Attack on Titan announcements. The manga ended years ago, the anime finally reached its brutal conclusion, and for a while it felt like the story had reached the only ending it could possibly have. Then September 9 suddenly became official Attack on Titan Day, and somehow the series has found a way to make the fandom collectively lose its mind all over again.

The Japan Anniversary Association has officially registered September 9 as the date dedicated to Attack on Titan, and the choice makes perfect sense. September 9, 2009 was the day Hajime Isayama’s manga first began publication in Kodansha’s Bessatsu Shonen Magazine. Seventeen years later, that date is being turned into an annual celebration of one of the biggest anime and manga franchises of the modern era.

And honestly? I’m completely on board with it.

Why September 9 Matters So Much to Attack on Titan Fans

For newer fans, September 9 might just look like another promotional date created by a giant entertainment franchise. For longtime readers, though, it represents something much more meaningful. This is the anniversary of the moment Isayama introduced readers to a world where humanity lived behind enormous walls, terrified of creatures that seemed almost impossible to understand.

Back in 2009, nobody knew what Attack on Titan was going to become. The early manga had an almost horror-mystery atmosphere, and the central question wasn’t simply ‘How do we defeat the Titans?’ It was ‘What are these things, and why does this world exist in the first place?’

That mystery eventually expanded into politics, war, inherited hatred, freedom, revenge, and the terrifying idea that there might not be a completely innocent side in a conflict. That’s one of the reasons the series has stayed relevant long after its original publication ended.

The anime adaptation took that impact even further. WIT Studio gave the early seasons an unforgettable visual identity, while MAPPA inherited the enormous challenge of bringing the final chapters to the screen. Whatever you think about the ending, the journey itself became one of the defining anime experiences of the 2010s and early 2020s.

The First Official Attack on Titan Day Has a Lot Going On

The first official celebration on September 9, 2026 isn’t just a symbolic anniversary. A major livestream is planned, bringing together several of the actors who helped make the characters so recognizable around the world.

Fans are expected to see:

• Yuki Kaji, the voice of Eren Yeager
• Yui Ishikawa, the voice of Mikasa Ackerman
• Hiro Shimono, the voice of Connie Springer

For me, this is probably one of the most exciting parts of the whole celebration. You can announce another piece of merchandise and I’ll probably shrug, but seeing the original cast together again immediately hits the nostalgia button.

There is also plenty of speculation about what the production committee might reveal during the broadcast. The exact announcements remain under wraps, but the franchise has already confirmed several anniversary projects, making it pretty clear that September 9 isn’t going to be a one-and-done marketing event.

And knowing the Attack on Titan fandom, people are going to analyze every facial expression and every suspiciously worded sentence from that livestream.

99 Chapters Free for 99 Hours Is Actually a Perfect Idea

One of the coolest anniversary promotions is happening through Magapoke, Kodansha’s digital manga platform.

For a limited period, fans will reportedly be able to read the first 99 chapters of Attack on Titan for free for 99 hours.

That number isn’t random.

September is the ninth month, the anniversary falls on the ninth day, and the world of Attack on Titan famously revolves around the Nine Titans. It’s exactly the kind of ridiculous-but-perfect numerical symbolism that makes an anniversary promotion feel like it was designed specifically for the fans.

If you’ve never read the manga, this is probably the best possible excuse to finally experience the original version. And if you’ve already watched the anime multiple times, I’d still recommend going back to the manga. Isayama’s artwork develops dramatically over the course of the series, and some scenes simply hit differently when you’re reading them in their original form.

There’s also something nostalgic about returning to those early chapters knowing just how much information was hiding in plain sight.

Hajime Isayama Is Also Bringing New Collector Artwork

The anniversary isn’t stopping at digital content. A new collection of commemorative merchandise will feature original illustrations by Hajime Isayama, including limited-edition art panels.

What makes these particularly interesting for collectors is that the panels will carry individual serial numbers. That instantly makes them feel less like ordinary franchise merchandise and more like dedicated memorabilia for people who have followed Attack on Titan for years.

The collection is expected to include 52 different panel designs, drawing from classic manga volume artwork as well as material associated with the Attack on Titan FLY art book.

Personally, this is the kind of merchandise I’d actually want to own. There is a huge difference between buying another mass-produced character figure and having a numbered piece of artwork connected directly to the creator’s original illustrations.

Is Attack on Titan Really Coming Back?

This is where things get interesting.

The story itself is finished. Eren’s journey is finished. The manga has concluded. The television anime has concluded. But the franchise is absolutely not finished.

Producer Tetsuya Kinoshita has previously discussed the possibility of additional projects, including feature films, animation experiments, and collaborations outside the traditional anime format. That doesn’t necessarily mean we’re getting Attack on Titan Season 5, and I think fans should be careful about jumping to that conclusion.

Instead, it looks more like the franchise is entering a different phase.

Rather than continuing Eren’s exact story, future projects could explore different corners of the universe. And that’s where I think Attack on Titan has enormous potential.

Imagine a serious historical story about the Great Titan War. Or a prequel exploring the early formation of the Walls. Or a completely different cast living through another period of Eldian and Marleyan history.

The world is big enough for stories that don’t need Eren, Mikasa, or Armin.

That’s probably the smartest way to continue the franchise without damaging the ending of the original story.

Attack on Titan 3 Could Be the Next Big Thing

The gaming side of the franchise is also attracting attention, with Attack on Titan 3 reportedly in development for major gaming platforms and next-generation hardware.

Studio MAPPA is said to be involved in creating new high-budget animation material specifically for the project, which immediately makes me curious. The previous Attack on Titan games had some genuinely fun ideas, especially the freedom of movement provided by the Omni-Directional Mobility Gear.

But imagine that gameplay concept with modern hardware, much larger environments, better destruction, more detailed Titans, and MAPPA-quality cinematic sequences.

That’s the version I’ve been waiting for.

A truly ambitious Attack on Titan game could potentially combine open-world exploration, large-scale Titan battles, character relationships, story missions, and multiplayer mechanics. If the developers actually take advantage of current hardware instead of treating it like another licensed anime game, this could become something special.

The Last Attack Is Another Reason Fans Are Paying Attention

Then there’s the cinematic side of the franchise.

Attack on Titan: The Last Attack brings the final anime material together as a theatrical experience, essentially reworking the concluding specials into one larger movie presentation. For fans who watched the final chapters at home, the idea of seeing those sequences on a massive screen is genuinely appealing.

The biggest selling point isn’t necessarily new story content. It’s the opportunity to experience the final battle with enhanced presentation, sound, and theatrical scale.

And let’s be honest: some Attack on Titan moments were practically designed for a cinema.

The Rumbling, massive Titan transformations, collapsing structures, aerial combat, and the sheer scale of the final conflict can feel completely different when you’re sitting in a theater with the sound turned up.

Reddit Has Already Started Doing What Reddit Does Best

Naturally, the announcement has sent the Attack on Titan community into full theory mode.

One of the biggest questions is whether Isayama could eventually return with a new one-shot or side story. It’s not an unreasonable theory, especially considering how major anniversaries often become opportunities for creators to revisit their worlds.

Other fans are hoping for a prequel.

Personally, I’d love that.

A story exploring the history behind the Titan conflict could answer some fascinating questions without reopening Eren’s finished narrative. The Great Titan War alone contains enough material for an entire anime season if handled correctly.

Of course, the fandom has also turned the announcement into a meme.

There are already jokes about Attack on Titan receiving another version of its ending, followed by a remaster, followed by a director’s cut of the remaster, followed by a theatrical edition of the director’s cut. Considering how many different forms the final part of the anime went through, I can’t even blame people for making those jokes.

That’s part of what makes this fandom so entertaining. We can argue about the ending for hours and then immediately make a joke about it five minutes later.

What I Actually Want From the Future of Attack on Titan

If I’m being completely honest, I don’t need another sequel.

I’d rather see the franchise expand sideways instead of moving forward.

Give me another historical period. Give me a character we’ve never heard of. Show me what ordinary people experienced during one of the wars we’ve only heard about through exposition. Explore Marley. Explore the Eldian Empire. Explore the origin of the Titans without turning everything into another Eren storyline.

That’s how I think Attack on Titan can remain interesting without becoming a franchise that simply refuses to end.

The original story already made its point. Now the universe has an opportunity to become something larger.

Attack on Titan Day Proves the Series Has Become More Than an Anime

The most impressive thing about September 9 isn’t actually the merchandise, the livestream, or even the possibility of future projects.

It’s the fact that Attack on Titan has become important enough to receive an official anniversary date.

Few anime manage to become genuine cultural landmarks. Even fewer remain part of the conversation years after their main story has ended. Attack on Titan managed it because underneath all the Titans, battles, twists, and spectacular animation was a story about freedom, fear, political power, inherited hatred, and the consequences of choosing violence.

That’s why people are still talking about it.

So when September 9 arrives, I’ll probably be doing exactly what thousands of other fans are doing: revisiting old scenes, remembering where I was when certain episodes aired, arguing about the ending all over again, and watching the anniversary livestream to see whether someone accidentally reveals something they weren’t supposed to.

The story may be over.

But Attack on Titan clearly isn’t done marching yet.
