I made a simple tool that automatically generates Anki deck from japanese text.
The text is tokenized and each token is searched inside a dictionary to create an Anki card. Additionaly for each token a list of cards regarding the single kanji is created. The single kanji cards are always ordered to stay before word cards, so that the learning process is consistent.
It is a bit slow, so if you have a lot of text be patient. You can also consider running it from cli.
Windows release: LINK
On Linux/Mac you can install it with pip if you have python3
pip install jankigen

Tested only on windows for now.
Let me know if you have any issue.
