I agree with this. This post doesn't actually say what the book is about, as it could be able Japanese pop culture, Japanese history, Japanese life...

On my desktop, I have to scroll down 3 pages before the first block of text, which again does not explicitly mention that it's a textbook for learning the Japanese language.
