So here's the stack of my new study materials and y'all... kanji in context is arguably the best reference book for kanji I've come across. I cannot praise it highly enough.
It's designed to be gone through three times. The first time is learning the kanji and the readings for the vocabulary in red. The second time is for review and all the unmarked black words. The third time is for mastery and the unusual, difficult, or obsolete words marked by diamonds. I love it a lot.
The workbooks are the real gems though. It has practice and a bunch of example sentences actually using the vocabulary. Two words really similar in meaning that you can't tell the usage apart? No problem here. You'll get to see how it's actually used and, by extension, continue building and reinforcing your vocabulary.
Overall, this is one of the best designed textbooks I maybe have ever seen. It's designed for intermediate/advanced learners, so it's probably not the best for people who are just starting out in their Japanese studies. That being said, there's such a gap for that level of learning it's really exciting to see such a great resource targeted at us!
