The Short Answer

There's a fuck ton more yen (Japanese currency) than US dollars. Supply and demand determines value. Higher supply means lower value. There's a much larger supply of yen than dollars while the demand for the two is roughly equal compared to the disparity in supply. So the value of the yen is lower. Much lower. If you took dollars to Japan and found someone who would let you buy a car in US dollars, you would only need $20K (maybe + a fee for letting you pay in dollars which is inconvenient for the seller).
