How hard its Japanese is, where to watch it, and what to watch before and after.

Last updated 30 October 2026

Anime by Japanese level › N1

The short answer: Ikkimi rates DEATH NOTE N1 for learning Japanese: long reasoning, formal words. Good for a beginner? No, keep it for later. It is among the hardest shows Ikkimi rates, hard even for advanced learners.

Ikkimi lists DEATH NOTE on Netflix and 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. On Netflix, turn on Japanese subtitles and every word becomes clickable.

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

How to learn Japanese with DEATH NOTE

Ikkimi lists DEATH NOTE on Netflix and 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.

On Netflix

On Netflix, turn on Japanese subtitles in the player, where your country’s Netflix has them for this title, and Ikkimi makes the line clickable. If there are none, open the Ikkimi popup, choose Find Japanese subtitles, and search Jimaku’s catalogue or load a 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 DEATH NOTE on Netflix or 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). At this level, turn on the English line under the Japanese at first, and keep only the words that come back.

  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.
