How to learn Japanese with The Seven Deadly Sins
Ikkimi lists The Seven Deadly Sins on Netflix. 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 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.
Add Ikkimi to Chrome
Get the extension from the Chrome Web Store and sign in.
Play an episode
Open The Seven Deadly Sins on Netflix. 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). Keep three to five words an episode, the ones that come up again.
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.
