I used to eat the whole wheat bread when I was in the States. Since I am back in Japan, the whole wheat bread is one of the few things I miss. For some reason, I noticed not many stories carry the 100% whole wheat bread in Japan. I see so many white bread (which I don't like) and other multigrain look-alike bread (the labeling is not too clear and I could not make out if they mix some refined grain among the whole grain). I have to go to a larger store to find the whole grain bread. Is this the similar experience you are having?
The expiration date for the bread is like 2 days. I think that is because the bread makers do not include the extra chemical to prolong the longevity of the bread. Back in the States, the loaf of bread lasts like a 6 to 10 days.
I am having a very difficult time to find the authentic peanut butter. The peanut butters I see on the regular stores in Japan are not a peanut butter in my opinion. They are like a peanut cream laced with extreme quantity of sugar (I don't like sugar). I used to buy Crazy Richard's at the local supermarkets in USA and I have to really look for a similar authentic peanut butter in Japan. The close one I found is the peanut butter made in Chiba; but, that peanut butter is sold only one store (among so many stores) in my neighborhood. If you have any suggestion on the store, please let me know.
