Wanikani is a great website for learning kanji. It was a godsend for me because I had a huge block before I came across this website. Despite this, I do have some quarrels with the system that wanikani uses.
My biggest issue (and the topic of this post) is that you learn one reading of a kanji when you learn that kanji, but then days later, it gives you vocabulary using a different reading. This is throwing me off so much because I didn’t get the same chance to learn the kanji reading in the vocabulary as I did the kanji reading that I did with the kanji section.
My suggestion: In order to improve this, I wish the website would give you both the most common kun’yomi and on’yomi readings while learning the kanji. This would make it easier to recall the possibilities while learning the vocabulary.
This may just be me who is having trouble with this though. Thoughts on this idea or your opinions?
