I need to ship an application to a school in Kyoto quickly (must arrive by the 15th of this month). I'm looking around at the various companies (FedEx, UPS, USPS, STFU, et al.) but I was wondering if anyone has any experience with the varying shipping companies and knows which would be able to send my papers out with speed and reliability.

I'm not too familiar with international express stuff, so any ideas as to how fucked I am in this situation (if I am as fucked as I think I am) would be appreciated.
If this package goes through, and a bunch of other documents get stamped, approved, and otherwise fucked with, I'll be in Japan by September...
