On the Kodokan website, I found some information about a program called the Kodokan School of Judo. http://www.kodokan.org/e_basic/school.html#intl
It looks like this is a school designed to take someone from nothing to First Dan. I've contacted the Kodokan International Department to ask for some more details, but have yet to hear back. If anyone has participated in this program, or knows more details about it, could you give me some more information?
