Learn Japanese with Assassination Classroom

How hard its Japanese is, real words from it with kana and romaji, where to watch it, and what to watch before and after.

Last updated 30 October 2026

Anime by Japanese level › N3

The short answer: Ikkimi rates Assassination Classroom N3 for learning Japanese: classroom talk, a teacher who explains. Good for a beginner? With some help. It sits in the middle of Ikkimi’s levels. A beginner can follow it with kana and romaji on every word, but it is easier after one or two simpler shows.

Ikkimi lists Assassination Classroom on Crunchyroll. What each service carries varies by country. On Crunchyroll, Ikkimi finds a Japanese subtitle file for the episode in Jimaku’s catalogue and lines it up for you.

The Ikkimi web app and Chrome extension come on one plan. The iPhone app is coming soon.

How to learn Japanese with Assassination Classroom

Ikkimi lists Assassination Classroom on Crunchyroll. What each service carries varies by country. Ikkimi does not stream anything: you watch on your own account, in Chrome on a computer, and Ikkimi adds a Japanese line you can click on top of the player.

On Crunchyroll

Crunchyroll rarely has Japanese subtitles. On a Crunchyroll episode, Ikkimi looks for a matching Japanese subtitle file in Jimaku’s public catalogue, loads it and lines it up with the episode by itself. If Jimaku has no file for an episode, you can search by hand in the Ikkimi popup or load a subtitle file from your computer.

  1. Add Ikkimi to Chrome

    Get the extension from the Chrome Web Store and sign in.

  2. Play an episode

    Open Assassination Classroom on Crunchyroll. The Japanese line appears on top of the video.

  3. Click the words you keep hearing

    The video pauses and the word opens: kana, romaji, meaning, JLPT level and a recording by a native speaker where one exists (never a computer voice; otherwise the line from the show plays again). Keep three to five words an episode, the ones that come up again.

  4. Review them later

    Kept words come back as flashcards on the Ikkimi website, with the scene and the line they came from, just before you would forget them.
