Every time currency conversion comes up I seem to be the only person letting newcomers know that the online currency converters will give the BANK exchange rate... what interbank excange rate is that day. What the CUSTOMER gets is always slightly less. That slightly less rate is the profit margin for the banks/cambios. I was just there & the US to JA was $1US=$104.20J$. If you expect the rate you see online, you will be disappointed. Make your own cheat sheet when you get there based on the rate of exchange. It fluctuates. Last summer it was $1US=~$98J. My first trip, $1US=$5.35. Lots of years & trips since then
