Attack on Titan Day Set for September 9 With 99 Free Chapters

Attack on Titan Day will arrive on September 9, 2026, with a time-limited manga reading campaign, commemorative merchandise, and a special livestream. The announcement is built around the date on which Hajime Isayama’s manga began serialization, giving fans outside Japan a clear set of official checkpoints to follow while leaving some overseas-access details unconfirmed.

What Was Announced

The official Attack on Titan anime website announced on September 2 that the Japan Anniversary Association has formally recognized September 9 as “Attack on Titan Day.” The date matches the manga’s September 9, 2009 serialization launch in the inaugural issue of Bessatsu Shonen Magazine.

The announcement includes a commemorative visual designed around the number nine and the series’ Nine Titans motif. It also lays out three fan-facing projects for September 9 rather than announcing a new anime season, sequel, or film.

First, the official Shonen Magazine manga app Magapoke will offer Attack on Titan through chapter 99 for 99 hours. The stated window is September 9 at 12:00 a.m. through September 13 at 2:59 a.m. Japan Standard Time. Because the campaign is capped at chapter 99, it is a substantial starting point or reread opportunity, but it is not a complete-series giveaway.

Second, special goods will go on sale September 9 at Magazine Shop, described in the announcement as Weekly Shonen Magazine’s first offline shop. The lineup will include goods using the new commemorative visual and newly drawn illustrations by Isayama showing Eren, Levi, and Erwin in formal attire. The official notice points readers to a dedicated campaign page and the Magazine Shop account for further product information.

Third, a commemorative livestream is scheduled for September 9 at 9:30 p.m. JST. Yuki Kaji, Yui Ishikawa, and Hiro Shimono are listed as scheduled guests, reprising their roles as Eren Yeager, Mikasa Ackerman, and Connie Springer. The streaming platform and additional details have not yet been announced; the anime’s official account is expected to provide them later.

Why It Matters

This package turns a historical publication date into a coordinated anniversary format that connects the manga, physical retail, and the anime cast. The 9/9, 99-chapter, 99-hour structure is unusually specific: it gives the campaign a built-in identity while directing fans toward the source material rather than only toward collectibles or a promotional video.

For the franchise, the timing also keeps the manga’s original starting point visible after the anime’s main story has concluded. The announcement is therefore best understood as a celebration of the series’ publishing history and continuing fan community. It may create a new annual touchpoint for readers, but the official notice does not claim that September 9 will become a recurring yearly event beyond this recognition.

The guest list adds a second layer of interest. Kaji, Ishikawa, and Shimono represent three long-running character voices from the anime, so the livestream could become a place for anniversary commentary or further information. However, no new project is promised in the announcement; any expectation of a sequel, spin-off, or fresh adaptation would be speculation until the official program says otherwise.

Context for International Fans

The free-reading campaign is announced through Magapoke, and the official notice does not specify worldwide eligibility, an English translation, or whether access will work identically outside Japan. International readers should treat the 99-hour offer as availability to verify, not as a guaranteed global release. The linked Magapoke page is the official place to check the campaign entry point, login requirements, and any location or account restrictions when the window opens.

For time-zone planning, the campaign begins at 11:00 a.m. UTC on September 8, 2026; that is 7:00 a.m. Eastern Time and 4:00 a.m. Pacific Time on the same date, using the daylight-saving offsets in effect then. The stated end, September 13 at 2:59 a.m. JST, corresponds to 5:59 p.m. UTC on September 12, or 1:59 p.m. Eastern and 10:59 a.m. Pacific. These conversions describe the Japanese schedule; the app may display a different local countdown.

The physical merchandise release is more straightforwardly Japan-based: the announcement names an offline Magazine Shop but does not provide overseas shipping information. Fans abroad should wait for the official shop details before assuming international ordering will be available. Likewise, the livestream’s international accessibility, subtitles, archive policy, and exact platform remain not yet confirmed.

What Happens Next

The next official update to watch is the streaming announcement on the Attack on Titan anime account. Before September 9, fans should also check Magapoke for the campaign page, confirm whether their account and territory can open the free chapters, and review Magazine Shop’s product and purchase information.

On September 9, the practical schedule is the manga campaign at midnight JST, merchandise availability at the named physical shop, and the cast livestream at 9:30 p.m. JST. Since the event notice warns that details can change, readers should recheck the official announcement on the day itself. At present, the confirmed news is a commemorative fan campaign—not a new adaptation announcement.
