Anyone know anything about G30 Master's Program in Japan?

I’m graduating in two semesters and looking to apply for the G30 Master Program in Japan, especially Kyoto University, Tokyo University and University of Osaka. I currently go to a top Canadian University, majoring in Pharmacology but my GPA isn’t stellar. I am wondering if those universities might be out of my reach, and it would be great if anyone know anything about the G30 programs in Japan and may be able to share some information (as information seems to be rather limited around here).

Thank you!
