If people don't write checks in Japan, how do they pay their bills?

Of course there is automatic transfer, but it is really easy to pay bills at any convenience store. Gas, electric, water, and phone bills all have barcodes on them. You just take the bills to a convenience store, they scan the barcodes, and you pay. If you phone was cut off because you were late paying, the phone will be turned on within a few minutes of paying. And there is no charge for paying at a convenience store!
