Good luck with that one. It sounds like one of these problems without any good solution. You know something is going to break because someone will screw up the conversion. I feel this is a case where it'd be better to have something totally different. Like time written in letters rather than digits. So that there would be no way to mistake one for the other. I work in finance, and it's always a lot easier to spot rescaling problems when dealing with jpy than any other currency. The fact that 100 yens ~ 1 usd makes any mistake glaringly obvious.
