I remain a Calpis virgin, despite my many years in Japan. However, I would have surrendered this status if these things had been available during my time there. I probably would have gone for the Calpis tart (top left) for certain and the cream bread (bottom left). However, I probably wouldn't go for the sponge cake (top right) and definitely wouldn't have touched the "cup jelly" (gelatin).
The tart and sponge cake cost 110 yen ($1.10). The jelly is, for reasons I can't imagine, 158 yen ($1.58) and the cream bread is 137 yen ($1.37). If you can get past the name which sounds like bovine urine, you can enjoy them from Family Mart convenience stores. (All jokes aside, Calpis is supposed to taste like yogurt and I'm sure is pretty tasty.)
