[Tsuwabuki]

I draw money out of my Citibank check card via 7-11 all the time for minimal fees. Just make sure it's a visa and not a mastercard. Mastercard is no longer accepted for check cards. The post office still does it, but it's more expensive.

Of course, I only do this in emergencies, or when I need to make big purchases my normal income in Japan does not cover.
