Definitely NOT recommended for people who want to learn a lot of practical Japanese language in a short time. Despite the title, it seemed to me that the book requires a great deal of effort to learn a lot of random things very quickly in a sort of childish kindergarden way ("This is a key. That's a book."), and definitely not in order of usefulness - why do I need to know how to say "one trillion mechanical pencils" before I learn toilet, passport, visa, taxi, bus stop, train station, train ticket, entrance, exit, ...? There is very little explanation - much of the material raises more questions than it answers, giving the student the feeling that they don't know how to use what they've learned except in the very few explicit examples given in the book.A very, very disappointing purchase.
