Doing a project on Japan and I need help!?

Why dont you google each question and youll get almost specific answers. Or go to the library and check out the encyclopedias(they have nearly all the info), almanacs(population questions) and possibly a childrens book on Japan(believe it or not, this really helps. The language is simple, there isnt a whole lot of info to sift through, and the pictures and maps can be really helpful)
