# A Chrome extension for learning Japanese from anime

> What it does on your show, and how to set it up.

**The short answer:** a Japanese-learning Chrome extension adds study tools on top of the videos you already watch: a Japanese subtitle line you can click, a dictionary, and a way to keep words as flashcards. **Ikkimi** is one, made for anime. It is [on the Chrome Web Store](https://chromewebstore.google.com/detail/ikkimi-%E2%80%94-learn-japanese/kknpmodmojiodjhbgapdgpabdehpnfcb) and works on Crunchyroll, Netflix and YouTube in Chrome on a computer. Click a word to see its reading in kana and romaji, its meaning and its JLPT level; keep it, and it comes back as a flashcard with the scene.

The Ikkimi web app and Chrome extension come on one plan. The iPhone app is coming soon.

## What does a Japanese-learning extension do?

Most do some of these:

- **Show Japanese subtitles** on the player, from the site’s own track or a file you load.
- **Look up words** when you click or hover, usually pausing the video.
- **Keep words** for review, as flashcards in the tool or in Anki.
- **Fix timing** when a subtitle file does not match the video.
- **Help you choose** shows or videos at your level.

Some are subtitle tools (Ikkimi, Language Reactor, asbplayer, Migaku, ManabiDojo); others, like Yomitan, are pop-up dictionaries for any page. Our [roundup of apps for learning Japanese with anime](https://ikkimi.app/best-apps-to-learn-japanese-with-anime/) compares them, with prices checked on 4 November 2026.

## What does Ikkimi add on each site?

- **Crunchyroll:** most episodes have no Japanese subtitles, so Ikkimi finds a matching file in Jimaku’s public catalogue and lines it up with Crunchyroll’s own subtitle timing by itself. [More](https://ikkimi.app/learn-japanese-with-crunchyroll/).
- **Netflix:** turn on Japanese subtitles in the player and Ikkimi makes them clickable, with a switch in Netflix’s control bar. [More](https://ikkimi.app/learn-japanese-with-netflix/).
- **YouTube:** Ikkimi switches the player to Japanese captions and badges each thumbnail with whether it has Japanese captions and its level from N5 to N1. [More](https://ikkimi.app/learn-japanese-with-youtube/).

On every site, a click on a word pauses the video and shows its reading in kana and romaji, its meaning, its JLPT level and a recording by a native speaker where one exists (never a computer voice; otherwise the line from the show plays again). Saved words get a yellow underline wherever they show up again.

## How do I install Ikkimi?

1. Add it to Chrome: Open [Ikkimi on the Chrome Web Store](https://chromewebstore.google.com/detail/ikkimi-%E2%80%94-learn-japanese/kknpmodmojiodjhbgapdgpabdehpnfcb) in Chrome on your computer and choose Add to Chrome.
2. Pin it: Click the puzzle-piece icon in Chrome’s toolbar and pin Ikkimi, so its popup is one click away.
3. Create your account: Sign up on [ikkimi.app](https://ikkimi.app/pricing) and choose a plan. The yearly plan starts with 7 days free; you add a card to start.
4. Play a show: Open an episode on Crunchyroll, Netflix or YouTube, on your own account. On Netflix, turn on Japanese subtitles in the player.
5. Click and keep words: Click a word in the Japanese line to see it, and keep the ones you want to learn.
6. Review on the website: Open ikkimi.app in the same browser, signed in. The extension hands your saved words to your account, and they come back as flashcards with the scene.

## What does it ask permission for?

- **Storage**, to keep your words, shows and settings in your browser.
- **YouTube, Netflix and Crunchyroll**, to show the Japanese line on their videos. It never looks at other sites.
- **jimaku.cc**, to find and download subtitle files.
- **languagepod101.com and innovativelanguage.com**, to play word recordings.
- **ikkimi.app**, to pass your saved words to your account.
