The Long Summer of August 31 Anime: SHAFT Studio Confirmed

The Long Summer of August 31 anime is official. Ikkado Ito's time-loop rom-com manga is getting a TV anime produced by studio SHAFT, alongside a separate live-action TV series. The reveal landed in late August 2026 — fittingly, right around August 31, the exact date the series traps its characters in. Below is a plain, spoiler-light rundown of everything that is confirmed so far, why the SHAFT name matters, what the manga actually is, and the details that have not been announced yet.

If you have not read the manga, do not worry: nothing here spoils how the loop resolves. This is written for the wave of readers typing "is there a Long Summer of August 31 anime" the week the news broke.

What was announced for The Long Summer of August 31?

Two adaptations were confirmed at once: a TV anime by SHAFT and a live-action television series. The announcement came from creator Ikkado Ito in late August 2026, tied to the series' signature date. Both projects are still at the "greenlit and announced" stage — the anime has a studio attached, and that is the single most concrete detail available right now.

The live-action series arrives even barer: no network, no producer, and no cast have been named. So the honest state of things is one solid fact per project — SHAFT is animating one, and a live-action drama exists — with almost everything else still to come.

Akibato does not stock merchandise for a title this new; a brand-new announcement has no figures yet. If you are a figure collector filling shelves while adaptations like this cook, you can browse Akibato's scale and prize figures shipped from Japan in the meantime — we will cover this series' merch if and when it is announced.

Who is making the anime, and why does SHAFT matter?

SHAFT is the studio behind some of the most stylistically distinct anime of the last two decades, which is exactly why fans reacted to the name alone before a single staff member was confirmed.

SHAFT's track record

Founded in 1975, SHAFT became a household name among anime fans through its adaptation of the Monogatari series, which began with Bakemonogatari in 2009. Its other signature works include Puella Magi Madoka Magica, March Comes in Like a Lion, Nisekoi, Sayonara Zetsubo Sensei, and Hidamari Sketch. Since 2005 the studio has worked closely with director Akiyuki Shinbo, whose avant-garde framing, rapid cuts, and heavy use of on-screen text became the studio's visual signature.

What SHAFT's style could bring to a time loop

No director has been announced for The Long Summer of August 31, so any specific staff talk is speculation. What we can say factually is that SHAFT has repeatedly handled two things this story needs: dialogue-driven comedy between a small cast, and a heightened, stylized visual language for stories that bend reality. A month-long August 31 that keeps repeating is a structure that rewards exactly that kind of playful, self-aware direction — which is why the studio pairing drew attention.

What is The Long Summer of August 31 about?

The Long Summer of August 31 is a time-loop comedy in which two high schoolers, Takaya Suzuki and Kana Takagi, are the only people who remember that the same August 31 keeps repeating. The loop runs for roughly a month before resetting, and Suzuki suspects it is tied to his very teenage, very unfinished summer to-do list — namely, getting a girlfriend before the holiday ends.

Tonally it sits between three genres: coming-of-age, romantic comedy, and light science fantasy. The hook is not the sci-fi mechanics but what two kids do with unlimited do-overs of the last day of summer — a premise built for both laughs and quieter, heartfelt beats.

Where the manga runs and how big it is

• Author: Ikkado Ito, whose earlier work includes I'm Not Meat.
• Magazine: Kodansha's seinen magazine Morning.
• Serialization: running since March 2023.
• Volumes: 13 tankobon as of August 2026.
• English: released in print by Seven Seas Entertainment and digitally via Kodansha's K Manga app.

Is there a release date or cast yet?

No. This is the part worth being clear about, because a thin SERP fills fast with pages that imply more than was actually said. As of early September 2026, none of the following have been announced for The Long Summer of August 31 anime:

• A premiere date or broadcast window for the TV anime.
• A director, series composition writer, character designer, or composer.
• Voice cast or a first trailer/PV.
• An episode count.
• For the live-action series: network, cast, and production timeline.

When a studio-only announcement is this early, the next concrete update is usually a teaser visual and a rough year, followed later by staff and cast. We will update as those land.

Where can I read the manga in English?

If the announcement made you want to start now, the manga is the only way in until the anime airs. English readers have two official routes: physical volumes from Seven Seas Entertainment, and digital chapters through Kodansha's K Manga app. Reading ahead also means you will not be waiting on the loop's payoff at anime pace.
