the food i've gotten at konbini in japan is on par with specialty gas stations, such as KwikTrip, Casey's, Wawa or Buc-ees in the US. I don't trust food at my 7-11 at home. in japan they get shipments of fresh food _at least_ daily. Soba, onigiri, sandwiches aren't necessarily junk food but they had plenty of those options as well. The US is only junk food.
