A few people have asked me for my suggestions for books to use to study Japanese, particularly at the Advanced level. As you may know, I hold a Bachelor's Degree in Japanese and lived with a Japanese host family for a year when I studied abroad. I've never taken the JLPT before but when we took a mock JLPT N2 test last year, I scored 97% (only 50 or 60% is needed to pass), so I'm planning to take the N1 level this July. These are the books I'm currently using to study.
Here are some sample shots from each of the books. First is the Grammar book, then the vocabulary book.
The Grammar book is set up for 9 5-day study weeks. Each day's lesson has 4-5 grammar points with explanations in English and Japanese, notes about the proper way to conjugate the new grammar, model sentences, and a short text at the end. My only complaint with this book is that I wish there were more model sentences. One is not enough for me!
