Hey, Tetsu ... you'll need
Adobe Acrobat (or another .PDF-creating program) for making .PDF files that contain two or more pages. If you don't have such a program, you can visit Adobe.com to look into creating a .PDF through a service that they provide online. (Since I have Acrobat, I've never used the service, so I don't know much more about it than that.)
Here are some links that might help point you in the right direction:

Hope that helps....
