How to learn Japanese with Blue Period

Ikkimi lists Blue Period 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.

  1. Add Ikkimi to Chrome

    Get the extension from the Chrome Web Store and sign in.

  2. Play an episode

    Open Blue Period on 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.
