Why doesn't Japan just divide the Yen by 100? 
I think the tradition within the country would outweigh any convenience it would have for the rest of the world.  The US hasn't even been able to switch to the Metric system, even though it's taught in school and used in math / science.  The costs involved with changing price tags, and re-organizing everything in their world would be pretty crazy.
