Yomichan Options

Profiles

Profiles allow you to create multiple configurations and quickly switch between them or use them in different contexts.

Profile name

Usage conditions

Usage conditions can be assigned such that certain profiles are automatically used in different contexts. For example, when Popup Content Scanning is enabled, different profiles can be used depending on the level of the popup.

Conditions are organized into groups which represent how the conditions are checked. If all of the conditions in any group are met, then the profile will automatically be used for that context. If no conditions are specified, the profile will only be used if it is selected as the Active profile.

Dictionaries

Yomichan can import and use a variety of dictionary formats. Unneeded dictionaries can be disabled.

Select a dictionary to import for use below. Please visit the Yomichan homepage to download free dictionaries for use with this extension and to learn about importing proprietary EPWING dictionaries.

Storage

Web browsers may sometimes clear stored data if the device is running low on storage space. This can result in the stored dictionary data being deleted unexpectedly, causing Yomichan to stop working for no apparent reason. In order to prevent this, persistent storage must be enable by clicking the "Persistent Storage" button below.

Yomichan is using approximately of .

Yomichan is permitted unlimited storage.

Could not detect how much storage Yomichan is using.

On Firefox and Firefox for Android, the storage information feature may be hidden behind a browser flag. If you would like to enable this flag, open about:config and search for the dom.storageManager.enabled option. If this option has a value of false, toggling it to true may allow storage information to be calculated.

If you are using Firefox for Android, you will have to make sure you have enough free space on your device to install dictionaries.

It may not be possible to enable Persistent Storage on Firefox for Android.

It may not be possible to enable Persistent Storage on Chrome-based browsers. However, the Yomichan extension has permission for unlimited storage which should prevent Chrome from deleting data.^[1]

Text Parsing Options

Yomichan can attempt to parse entire sentences or longer text blocks on the search page, adding furigana above words and a small space between words.

Two types of parsers are supported. The first one, enabled by default, works using the built-in scanning functionality by automatically advancing in the sentence after a matching word.

The second type is an external program called MeCab that uses its own dictionaries and a special parsing algorithm. To get it working, you must first install it and a native messaging component that acts as a bridge between the program and Yomichan.

Anki Options

Yomichan supports automatic flashcard creation for Anki, a free application designed to help you remember. This feature requires installation of the AnkiConnect plugin.

Enable Anki integration

Notice for Mac OS X users: If Yomichan has issues connecting to AnkiConnect, you may have to tweak some system settings. See this link for more details.

Specify the information you would like included in your flashcards in the field editor below. As Anki requires the first field in the model to be unique, it is recommended that you set it to {expression} for term flashcards and {character} for Kanji flashcards. You can use multiple markers per field by typing them in directly.
