My guide to Japanese grammar has been helping people learn Japanese as it's really spoken in Japan for many years. If you find yourself frustrated that you can't understand Japanese movies or books despite having taken Japanese classes, then this book is for you. It will help you finally understand those pesky particles and break down grammatical concepts that will allow you to comprehend anything from simple to very complex sentences. You will also learn Japanese that's spoken by real people including casual speech patterns and slang, stuff that's often left out in most textbooks. Don't take my word for it, just check out my website and order this book to have it handy wherever you go.
