Kokichi Sugihara

Below, you can see several titles of books of Japanese scentist Kokichi Sugihara. He was professor of Unversity of Tokyo for a long time, but now he moved to Meiji University.

His page at the site of University of Tokyo, but because of moving it will be removed soon. I don't know his other address.

Also, there are paper models of impossible figures by Kokichi Sugihara at the site.
