Yomichan

Yomichan is an Anki plugin built to solve the various annoyances I encountered when trying to read Japanese books on my computer. This tool makes vocabulary mining trivial by allowing you to focus on your reading. Yomichan can be used in conjunction with Yomichan for Chrome to further enhance your learning experience by enabling flash card creation from your web browser.

Motivation

The software I was using for mining up to now was Rikaichan. I'm sure most people studying the Japanese language are familiar with this browser extension and probably have it installed in Firefox. Although pretty amazing, this tool is bound to Firefox. Firefox is obviously not a book reader: it doesn't behave well with large text files, doesn't remember where you last stopped reading, and most importantly there was no integration with Anki. As such, adding new vocab to my Anki deck was annoying; I wanted to be able to do this with one mouse click. After several hours of work, Yomichan could do this and much more.

Installation

Yomichan can be downloaded from the its Anki shared addon page. There is an automatic update checker included in the plugin that (unless you disabled it in options) will notify you when new versions become available. Developers can also clone the repository on GitHub; be aware that Git LFS is required for downloading the included Japanese data files.

Usage

1. Make sure you are running the latest version of Anki.

2. Open your vocab deck and note the fields that are used in your deck.

   

3. Launch Yomichan from the tools menu inside Anki.

4. Open the text file you want and you will see its contents in the Yomichan. Your layout and color scheme will look different because the screenshot shows my personal settings.

   

5. To look up words hover your mouse over them while pressing the middle mouse button (usually this is your scroll wheel). You can also press and hold shift instead if you like (or your mouse has no center button).

6. To set up your Anki deck for Yomichan select Preferences from the Edit menu and you should see a screen that looks like this:

   

7. Now you should add markers such as {expression}, {reading}, {reading} and {sentence} to specify how new cards should be created. Card fields will vary depending on your deck model. If you want to be able to use AnkiConnect via the Yomichan extension for Chrome, tick the checkbox labeled Enable AnkiConnect as shown above.

8. When you look up definitions you will have the option to create Anki cards for them with one click. You will see the icons for performing these actions next to each item. Icons for actions which update your decks won't show up if Anki thinks you can't add a fact with those items. This likely means that they would either be duplicates of existing cards in the deck or that Yomichan hasn't been properly set up for your deck model.

   

   Here is what the icons mean (in order from left to right):

   • Add term in Kana form even it can be written in Kanji (e.g. べんきょうか).
   • Add term as it appears in the dictionary including Kanji (e.g. 勉強家).
   • Copy the expression, reading and definition for the term to the clipboard.

Shortcuts

By request, I've added several keyboard shortcuts which make Yomichan even easier to use:

Shortcut	Command
Shift	Search under cursor
]	Move search cursor forwards
[	Move search cursor backwards
Shift + Ctrl + #	Add current Kanji at index 0 - 9 to deck
Ctrl + #	Add current term at index 0 - 9 to deck
Alt + #	Add current term at index 0 - 9 to deck as Hiragana

AnkiConnect

AnkiConnect is a revolutionary feature which allows external applications to communicate with Anki, making it possible to query decks and create new flash cards directly. This feature must be enabled through the preference dialog prior to use. AnkiConnect is also available as a separate plugin for those who want to get this feature in a smaller package.

Importing Vocabulary

Yomichan is capable of importing vocabulary lists from plain text files and the vocabulary deck database the Amazon Kindle automatically generates when you look up words in the built-in dictionary (this file can be found as /system/vocabulary/vocab.db). Note that importing does not create flash cards automatically, but rather outputs the contents of the file to the Vocabulary and Kanji panes so that you can add facts the same way as when reading within Yomichan.
