## How to learn Japanese with Castle in the Sky

Ikkimi lists Castle in the Sky 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](https://chromewebstore.google.com/detail/ikkimi-%E2%80%94-learn-japanese/kknpmodmojiodjhbgapdgpabdehpnfcb) and sign in.
2. Play the film: Open Castle in the Sky 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). Keep three to five words an episode, the ones that come up again.
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.

The film runs about 2 h 05, so you can split it over a few evenings and rewatch the scenes you liked.
