Learn Japanese with Overlord
How hard its Japanese is, where to watch it, and what to watch before and after.
Last updated 30 October 2026
The short answer: Ikkimi rates Overlord N2 for learning Japanese: grand formal speech, game and ruler words. Good for a beginner? Not for beginners. It suits learners who already follow easier shows. Expect to click a lot of words at first.
Ikkimi lists Overlord 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 Overlord
Ikkimi lists Overlord 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.
Add Ikkimi to Chrome
Get the extension from the Chrome Web Store and sign in.
Play an episode
Open Overlord on Crunchyroll. The Japanese line appears on top of the video.
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.
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.
