Essential Grammar Essential Japanese Grammar: Write & Speak Japanese Like a Native! a Comprehensive Guide to Contemporary Usage, (Paperback)

I'm not really a fan of textbooks and such, but this is actually a really good grammar book. It has tons of grammar patterns inside, with many natural sentence examples for each one. The more abstract the grammar, the more sentences there are, which is great. The sentences are in Japanese but also have Romaji and English. There's an index for looking up certain grammar points, and also references to similar grammar points for certain ones. You can't go wrong with this book honestly. Perfect for taking along with you somewhere that a phone wouldn't be allowed but you still want to study. Just reading the example sentences alone are great practice, not to mention the great explanations that go along with those unknown grammar points. If it's a grammar book you're looking for, or even just a book for getting in some Japanese practice, you can't go wrong with this one. I don't however, recommend this for just straight up learning Japanese. This is for upper beginner and intermediate learners, or to be used as an additional resource for looking up grammar points in your initial learning journey, IMO.
