How to learn Japanese with Sweetness & Lightning
Ikkimi lists Sweetness & Lightning 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 Sweetness & Lightning 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). 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.
