I might be in the minority but my love with the 7-11 sandwiches and most bread in Japan was very brief. I like crusts that aren't soft and nearly all bread and sandwiches in Japan are very, very soft without much bite. Most of the bread-based food is also just way too sweet, even the savory things.

The 7-11 sandwich shown further down in the article is probably one of the worst ones you could get (IMHO).
