HELP! What kind of cheese is this?

I recently went to Korea and bought what I'm assuming are Japanese cheese snacks. Would anyone have any idea of what these sticks are called so I can buy something similar where I live?

(In the photo the two labels are "Cheese Roll With Squid" and "Smoked Cheese Sandwich", I want to find what the Smoked Cheese Sandwiches are)

I've tried googling "smoked cheese sandwich snack" and "Japanese smoked cheese snack" and haven't had any luck, could anyone help?
