As for student funding sources for Japan, here is what I can recommend:
1) JSPS=Japan Society for Promotion of Science (General site http://www.jsps.go.jp/english/index.html, scroll down on the right for program/funding opportunities). For example, the JSPS Summer Program (http://www.jsps.go.jp/english/e-summer/index.html#07). The program is offered to young pre- and postdoctoral researchers from the five countries of the US, UK, France, Germany and Canada. Held over a 2-month period in the summer, the program provides the participants with an orientation in Japanese language and culture and an opportunity to do cooperative research at a Japanese university or research institute. The orientation is held at the Graduate University for Advanced Studies (Sokendai) during the first week of the program. It comprises Japanese lessons, home stay and other components (which may vary by year). After the orientation, the participants go to their respective host institutions where they conduct joint research under the guidance of their Japanese host researchers. At the end of August, the participants re-gather before going home to present reports on their summer experiences.
2) Invitation Fellowships. http://www.jsps.go.jp/english/e-inv/main.htm
