Anyone living in or visiting Japan is no stranger to walking around with a bucketful of coins in their pants/purse. The excitement before your first Tokyo subway ride soon quells as you're greeted by a flurry of coins spraying from the ticket machine like a Las Vegas slot hitting the jackpot. Tourism stamina wanes as you really start feeling that 10-pound metal load clinking in your pocket.
I don't know why Japan loves coins, but the reason rests in the fact their paper money starts at 1000 yen, roughly a $10 bill back in better economic times. During my years living here, I've developed a few techniques for coping with coin overload.
