Japanese Math Problem

Yes, I’m back in Switzerland and have been for half a week now, but I still owe you the following math problem.

If you go to a Japanese bank to buy four rolls of fifty five-yen pieces each, how much will that cost?

    Well, this is too simple, so there must be a catch. 50 coins per roll, 4 rolls = 200 coins; 5 yen each = 1000 yen. So – what’s the catch? Do they no longer make 5 yen coins, so you are buying collector’s items and they charge a premium?

    No, that’s not the catch. The catch is the service charge: total cost 1315 yen. Gotta love Japanese banks…

    The easiest solution would be to go to several convenience stores and ask for 5-yen coins. I’d probably save the 31.5% surcharge that way, but doubt that I could justify the walkabout for what amounts to 3-4 dollars. How much would a coin dealer charge?

    Well, for rolls of state quarters in the US coin dealers charge $10.50 to $12.50 depending upon the state and mint mark. This is for a $10 roll. Of course you can get rolls of coins here from a bank at no premium if you don’t care about which state or mint you get.

    I tried to get my Japanese account closed, the account I used while an intern here. It took them half an hour to figure out that they couldn’t close it if I didn’t also bring my cash card and the stamp I’d used to open it (the stamp we made in one of our cultural experiences by scratching a block of soapstone). I left with a new ATM booklet, and the knowledge that I had gained some interest on my money, to the tune of 1 yen. Grand total in the account: 253 yen. I wonder how they justify spending that half hour…
