well, i have to say i was pretty disappointed with this book. maybe i was naive to think that, as a beginner, i'd be able to learn japanese from a book. still, there's way too much information here for my brain to process. even though it's a japanese I book, it requires a basic understanding of japanese (which, sadly, i don't have). also, i ran into a lot of concepts that i wouldn't have known if i wasn't an english major. if you don't know what the words 'fricative,' or 'subjunctive' mean, don't buy this book!
