What kind of financial documents do I need to submit and what is the photo size?

Thank you very much for your reply.
Furthermore I would like to know about what kind of financial support documents do I need? I have no idea about this. I kindly request you can you explain about this? And also is it necessary to show financial support documents , because I want to apply transit type. My destination is Japan and I am a student yet?

Moreover I want to know about that what is the size of photo?
