In all fairness to the rest of us, Japan does have some of the very nicest woods in the world to plane (cedars). After a weekend of planing #2 cherry, which is not as nice to plane as FAS cherry, I planed some soft, straight grain pine and suddenly my plane was amazingly sharp, without any action on my part.
As for the nice 8" shavings, wow! I've gotten shavings that thin before, but usually not the full length of the plane blade. Getting that kind of consistency across the whole length of the plane is amazing.
