Attack on Titan has officially been given its own day, and the franchise is celebrating in the most Attack on Titan way possible: with 99 announcements.
September 9, 2026, has officially been recognized in Japan as Attack on Titan Day, commemorating the date Hajime Isayama’s manga began serialization in 2009.
To mark the occasion, the franchise unveiled an enormous collection of announcements covering manga, anime, movies, games, merchandise, events, and international collaborations.
The number 99 is far from random. September 9 connects directly to the series’ famous Nine Titans, while the manga itself began publication on September 9, 2009.
The anniversary campaign has therefore turned the number nine into the central theme of the celebration.
The official Attack on Titan portal describes the campaign as 99 news reports from around the world, making this one of the franchise’s largest anniversary celebrations yet.
And fans don’t have to wait to see what some of those announcements contain.
The First Major Surprise: 99 Chapters Are Free
One of the most immediately useful announcements for fans is a special manga campaign on Magazine Pocket.
Beginning at midnight JST on September 9, readers can access the first 99 chapters of Attack on Titan for free for 99 hours. The promotion runs until September 13 at 2:59 a.m. JST.
That is particularly significant because the first 99 chapters cover a substantial portion of the story and allow new readers to experience the series without immediately committing to the entire manga.
It also fits perfectly with the anniversary’s theme: nine, 99, and the original September 9 serialization date are being used throughout the campaign.
Hajime Isayama Returns With New Artwork
The celebration also includes a brand-new illustration from creator Hajime Isayama.
The official announcement describes it as a newly drawn commemorative illustration created specifically to celebrate Attack on Titan Day and express appreciation toward the franchise’s fans.
This is notable because Isayama’s involvement gives the anniversary campaign something beyond merchandise and corporate collaborations.
The creator himself is participating in the celebration, giving longtime fans a new piece of official Attack on Titan artwork to mark the occasion.
The campaign is also bringing new merchandise featuring Isayama’s artwork of Eren Yeager, Levi Ackerman, and Erwin Smith dressed formally.
Attack on Titan is Getting an Official YouTube Channel
Another major development is the launch of an Official Attack on Titan YouTube Channel.
According to the franchise’s official announcements, the channel will feature a range of content for fans around the world, including limited-time anime streams and exclusive special features.
The channel is also being used for a special Attack on Titan Day livestream scheduled for September 9 at 9:30 p.m. JST.
The livestream will feature the Japanese voice actors for Eren, Mikasa, and Connie: Yuki Kaji, Yui Ishikawa, and Hiro Shimono.
That makes the livestream particularly interesting because the franchise has promised to deliver “a lot of information” about Attack on Titan during the event.
The Movies Are Returning to Theaters
The celebration isn’t limited to digital content.
The franchise has also announced theatrical screenings of two Attack on Titan films in premium formats.
Attack on Titan Part 1: Guren no Yumiya will return to theaters in SCREEN X, 4DX, and ULTRA 4DX on October 23, 2026. Meanwhile, Attack on Titan: The Final Season – The Last Attack is scheduled to receive similar screenings in 2027.
For a franchise whose main television story concluded in 2023, these theatrical projects demonstrate that Attack on Titan is still being actively maintained as a major theatrical and commercial property.
And Then There Is Attack on Titan 3
The anniversary also brings new attention to Attack on Titan 3, Koei Tecmo’s upcoming action game.
The official franchise site confirmed that MAPPA is producing the game’s opening animation, and a new opening-animation key visual was unveiled as part of the 99 announcements.
This is especially interesting for fans because MAPPA’s name is closely associated with The Final Season. However, this announcement concerns the game’s opening animation, not a new television anime season.
That distinction matters.
Does the 99-Announcement Campaign Mean Something Bigger Is Coming?
Naturally, the scale of today’s celebration has already encouraged speculation.
With 99 announcements, new Isayama artwork, a new official YouTube channel, theatrical projects, a major game announcement, manga promotions and a special livestream all arriving together, some fans are wondering whether the campaign could contain an even bigger surprise.
But at this point, there is an important distinction between what has been officially announced and what fans hope might be announced.
The official Attack on Titan campaign has indeed promised 99 pieces of news, and many substantial projects are already included.
However, there is currently no official confirmation of a new television anime season or a continuation of the main story in the announcements released so far.
That hasn’t stopped speculation, but it should remain speculation until the franchise itself confirms something.
Attack on Titan Isn’t Finished Being a Major Franchise
The biggest takeaway from Attack on Titan Day may therefore be less about a single announcement and more about what the entire campaign represents.
The manga ended its serialization years ago, and the anime’s main story concluded in 2023. Yet the franchise continues to receive new games, theatrical screenings, merchandise, special events, official digital content and international collaborations.
According to Pony Canyon, the manga has surpassed 140 million copies in circulation worldwide, highlighting just how enormous the series’ legacy has become.
And now, September 9 has officially become part of that legacy.
Whether fans are revisiting the manga, watching the new livestream, collecting the anniversary merchandise, returning to theaters or simply waiting to see all 99 announcements, Attack on Titan Day makes one thing clear:
The story may be over, but the Attack on Titan phenomenon is nowhere near forgotten.
