Depositing Coins

I have a bunch of coins that have been piling up, and I was going to deposit them into my Yucho Ginko account, but the convenience stores I've gone to only accept cash, and apparently the Aeon grocery stores accept coins but they don't accept a Yucho cash card, only aeon ones and international ones, so I don't know what else to do. the 100 yen coins are easy to use at vending machines, but I have a lot of 5, 1, and 10 yen coins that I'd rather not sift through in front of a cashier. Anyone know where I can deposit them if at all possible?
