Assassination Classroom: Our Time is lining up as a clean coming-soon anime movie story, with an 87 minute runtime showing up ahead of its March 20 Japan release and the official site confirming Masaki Kitamura and Lerche on the project.

TL;DR

The movie is officially set for nationwide release in Japan on March 20, 2026, and major listings show an 87 minute runtime. The biggest missing pieces right now are international rollout details and how much of the film is truly brand-new versus previously unanimated material.

Key Details

• The official movie site lists a nationwide Japan release date of March 20, 2026.

• The official cast and staff page lists Masaki Kitamura as director and Lerche as the animation studio.

• Pia lists the movie at 87 minutes.

• The checked sources describe the film as covering Assassination Classroom material that had not previously been animated for TV.

• No overseas theatrical, streaming, or dub plan was confirmed in the sources reviewed.

Breakdown

This is the kind of anime update fans actually like, because it is built on official pages and concrete release details instead of loose social chatter. The March 20 date is already on the movie’s official site, so this is clearly in real rollout mode now.

The staff piece matters too. Lerche is a familiar name for the franchise, and Masaki Kitamura being listed as director gives the project a clear creative anchor instead of leaving fans guessing who is steering it.

The 87 minute runtime also helps set expectations. That is long enough to feel like a proper theatrical package, but still short enough that fans will naturally ask how much of the movie is new material and how much is a selective adaptation of scenes that were skipped before.

That is the real curiosity hook now. The sources point to previously unanimated material, but they do not fully map out the exact split between fresh scenes and adapted leftovers. So the movie feels real and close, but not fully explained yet.

What to Watch Next

• Any new trailer or TV spots before March 20

• More detail on what previously unanimated material is included

• International streaming or theatrical rollout announcements

• Dub news, if the movie gets picked up outside Japan
