KanjiTomo is a program for identifying Japanese characters from images:

KanjiTomo main screen

Kanji lookup is done by pointing the mouse to any image on screen (either from a file, program or web page). Dictionary lookup is done at the same time. Horizontal and vertical text are both supported.


The latest version of KanjiTomo can be downloaded here (link to MediaFire) Unzip the package to any directory and double-click KanjiTomo.jar or launch.bat to run the program. If you are upgrading from previous version of KanjiTomo, you can use Settings -> Import settings to load your old configuration.

Java is required to run the program. KanjiTomo has been tested on Windows 10 operating system, other operating systems might also work but are not supported. Japanese fonts must be installed.
