Yomichan Setup Tutorial

What is Yomichan?

Yomichan is a browser extension that allows you to look up Japanese words with both the meaning and the reading on web pages with ease. As you can see, I made a dedicated tutorial for it, even though the process is simple and there are already guides out there, only so I can stress how it is a very important tool when it comes to learning Japanese. Yomichan also has extra features such as Anki flashcard creation.

Getting Started

Yomichan is available for both Chromium and Firefox based browsers. You can find the respective versions below.
Chrome Web Store
Firefox Add-Ons
Once installed, it will open a new tab page, just close it for now so we don't confuse each other.

Acquiring Dictionaries

When you first install Yomichan, you need to load dictionaries into it in order to use it.
These come in .zip extension and are not to be extracted by the user.

You can find my collection of Yomichan dictionaries below. This will have everything you need and (probably) don't need. 🙂

Installing Dictionaries and basic usage

  1. Click on the yomichan-icon icon in the browser toolbar.
  2. Click on the cog icon to access the settings page.
  3. On the left sidebar, click on "Dictionaries" and then click on "Configure installed and enabled dictionaries…"
  4. Click the "Import" button on the bottom.
  5. Here's where you select the dictionaries to import. Please only import the following. Do not import every dictionary if you don't need to.
    • [Bilingual] JMdict (English).zip
    • [Bilingual] 研究社 新和英大辞典 第5版.zip
    • [Kanji] KANJIDIC (English).zip
  6. Please wait for the dictionaries to import. This could take a while if you are using a mechanical hard drive.
  7. Once complete, you can test Yomichan by holding down the Shift key and hovering over Japanese text. Here is a sample: 日本語. It will display a pop up box displaying the definitions separated by dictionary.
    Click anywhere outside of the box or press the Esc key to dismiss. Click on an individual kanji in the headword to view kanji information (only functional with KANJIDIC installed).
  8. You can click the audio button to hear the word being pronounced by a native speaker.

Yomichan Demo

Pop up box size can be edited with advanced settings enabled.
A full dark mode can be enabled in the settings too.

JMdict is the dictionary hosted on Jisho.org. Jisho.org is not its own dictionary, rather it's a portal that accesses JMdict. This is the most common Japanese to English dictionary.

研究社 新和英大辞典 第5版 (Kenkyuusha New Japanese-English Dictionary, 5th Edition) is a Japanese-English dictionary intended for Japanese people. It has many example sentences which can prove to be very useful for Japanese learners. A variation of this with example sentences truncated called is [Bilingual] 新和英.zip can also be found in my dictionaries collection.

KANJIDIC is a kanji dictionary, it allows you to view information of individual kanji.

You can use the search icon icon or the Alt+Ins keyboard shortcut to access Yomichan Search. Where you can use Yomichan as a standalone Japanese to English dictionary.

Allowing access to file URLs

Enabling this allows you to use Yomichan on local files such as .HTML files.

PDF Files

On Chrome, it is impossible to use Yomichan on PDF files.

Chromium:
- Right click the yomi icon
- Click "Manage Extensions"
- Enable "Allow access to file URLs"

Firefox:
- Enabled by default.

Bonus: Adding Forvo extra audio source

You may encounter missing audio with the default Yomichan audio sources, adding Forvo will help fill in the gaps.

Thanks to jamesnicholas for this wonderful add-on!

This requires you to have Anki (2.1 and newer) installed and open on your computer to work.

  1. Copy this code 580654285
  2. In Anki, in the menu at the top, click on Tools, then Add-ons.
  3. In the new window, click Get Add-ons... and paste the code 580654285 into the text box and click OK
  4. Restart Anki by closing it and opening it back up again.
  5. In the Yomichan settings page cog, click Audio on the left, and then click on Configure audio playback sources...
  6. Click Add and then select Custom from the drop down menu.
  7. Now where it says Custom audio source (?), select the type JSON from the drop down menu.
  8. In the URL text box, enter this http://localhost:8770/?expression={expression}&reading={reading}

Google Play

Importing a dictionary is a very processor intensive process and will take a long time depending on your phone. Please be patient.

Tap on a word to look it up. In the case that it is not working, you may need to turn off the modifier key.
