Summer Wars movie book

I came across Summer Wars movie book at Kinokuniya. So tempted to buy, but it’s all in japanese and i dont really understand what they are really saying. Anyways, a major portion of that book, my guess has a lot of director commentary about the movie. It shows numerous shots of the film, much like a story board and almost every one of them has short comments. The thing is, that it is all written in Japanese. If anyone out there would be so willing to help me to translate them, i would very very much appreaciate it!
