Japanese people take their calculators very seriously.

My dad recently sent out a link to this video with this commentary:

The Japanese culture seems to try to perfect their methods in whatever they do.  Usually, there's a ranking system to denote the proficiency of their skill level.  This is done in the martial arts, fine arts, and even the soroban (abacus).  Now, it's the calculator.  Must say, that girl has pretty fast fingers.
