For most of the food in convenience stores that you buy in Japan, you really just have to guess what it is. The majority of items aren't labelled in English and let's be honest they eat such bizarre things that most of the time you're guess is going to be a bit wide of the mark. Below is a very good example of this.

Looking at the image on the packet, you think to yourself "this must be a package of cut up hot dogs". Why the Japanese would sell a packet of cut up hot dogs though is besides the point. I mean why do they eat any of the things they do? (examples: Sea Urchin? Looks and tastes like an unbrushed tongue; Pork knuckle? It's a pigs fucking foot. )

Pulling it out of the package and smelling it you start to have your doubts. Pop it in your mouth, it's definitely not a sausage related product. Luckily, given the myriad other things it could be, it's just cheese. Just cheese. Phew.
