Haven't been to Japan (or any other Asian country that has these sandwiches) yet, but they remind me of something that's pretty common in Europe: tramezzini (https://en.wikipedia.org/wiki/Tramezzino https://en.wikipedia.org/wiki/Tramezzino). These are also sold packaged in various stores. The bread is basically the same as toast bread, sometimes with the crusts removed, sometimes not. You can eat them cold or toasted (using a special device of coarse, not a regular toaster).
