Convenience store yenny jar

For almost five years I've been putting yennies into a jar at convenience stores ("yenny" is my name for a one-yen coin, roughly equal to a U.S. penny). All this time I had no idea what it was for. I probably asked when I first arrived here, but my Japanese was too poor to understand the response. Since then I've just been tossing my annoying small change into the yenny jar. So finally I asked about it today, and found out it is a charity for the deaf and hard of hearing. After that, I tossed in substantially more than a penny's worth.

ONE GOOD DEED: Donate to a convenience store charity for the head of hearing.
