Finding a way out of a tangled web of financial aid

I've reached the end of the road for graduate school loans. Well, I was finally accepted to a master's program at my first choice school: Waseda University in Tokyo, Japan. Little did I know that funding my adventure in higher education would prove so ridiculously troublesome and depressing. My situation is easily summed up as follows: no one wants to give me a loan. In detail, it goes something like this: I cannot receive any kind of federal loan for graduate school, as my university doesn't admit many American students and as such has no relationship with the Department of Education here in the states--this means that Stafford loans are out of the question. Also, it is an impossibility for the university to get a FAFSA number through the DOE (thus allowing for federal funds) due to the length and intensity of the process and the relatively few American students at the school. I've talked with both the university, and the DOE on that one. I also seem to have hit a roadblock with private loans. I have found many loans that allow deferred payment and disbursement of funds directly to me, yet during the application process I always encounter the mysterious "eligibility list" of universities they approve or do not approve of--which of course Waseda is not on, excluding me from the loan. After speaking with a few financial aid officers, I realized that these lists are of universities that banks have relationships with so they can determine if the student is still enrolled at full-time (and thus still eligible for the loan). So it looks like private loans are out, too. I've checked hundreds of them, with no luck. The university itself offers no loans to foreign students, and has no relationships with any US financial institutions. As for scholarships, I will undoubtedly get them--and have been told as much--however they are not awarded until after matriculation and the initial tuition payments, which I would need a loan to make. I also have no way of knowing how much I'm getting yet. So what is a foreign-enrolled US citizen to do, with no one to loan him a dollar and his dream school slipping away? That's what I'm asking you. This has been one of the most disheartening experiences of my life: a long, detailed admissions process fraught with doubt that eventually resulted in the wonderful news of admission to my dream school, and yet now I have no way to finance it--even with the almost certain possibility of scholarship. Are there any options I haven't tried, or haven't thought of here? Is there anything I can do?
