Some time ago, The Japan Foundation created a website to help Japanese students learn the type of Japanese that is often heard in anime and manga. While it’s got some decent content, I’ve rarely ever heard anyone mention the site. That’s probably because they stuck all of the content into a crappy flash application. You can’t view it on mobile, you can’t copy and paste text, you can’t resize it, you can’t do ANYTHING useful.
So, I dumped some of their content into Anki decks so that it would be possible to actually learn something from it. I have made a deck containing phrases, and a deck with grammar points. This is only a portion of the total content from the site, but I felt that these parts would probably be the most useful and work the best in a flashcard format.
The grammar deck in particular is a bit dense with all of the information available, but I thought it best to put too much info rather than too little. You can of course customize which fields appear on your cards, since Anki gives you complete flexibility to display the cards as you like.
One cool aspect about the site was that it has 8 different Japanese character archetypes who all speak differently. I have kept this aspect in the flashcards by indicating which character the card is for. There is also full audio, so you can hear the personal spin that each character puts on the phrases.
After studying the cards, there is still some cool stuff to go back on the website to do. For instance, they have several manga stories that you can read, which utilize all of the phrases and grammar.
Content difficulty is probably Upper Beginner – Intermediate. You should probably have at least a good command of JLPT N5 grammar before tackling these.
