How to learn Japanese with Kaguya-sama

Ikkimi lists Kaguya-sama on Crunchyroll and 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 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 Kaguya-sama on Crunchyroll or Netflix. 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.
