This collection of Anki decks for Japanese learners, spread over 10 parts, is an absolute must for beginners. It includes standalone expressions as well as phrases with said expressions. It also contains images and, most importantly, audio produced by native speakers. This is where it really shines and makes it all worthwhile.
Having said that, the lack of linear progression throughout the decks is pretty bad. You learn the common expression 素晴らしい (subarashii) only by the time you get to deck 7! This happens often and feels like a wasted opportunity to make progression more meaningful.
Also I take issue with the fact that there are so many lent expressions from English (the so-called garaigo). Those are often nearly identical to the English words and don’t really need to be memorized with flashcards since they are so easy.
All in all, it’s a fun deck to churn through and I can recommend it!
