Over here in England, we have Japanese shops which sell these kinds of goodies, albeit not in the same range or diversity as you could get from Japan.
I actually really like visiting the japanese snack shops, the way that they display them is an enjoyable experience in it's own right. Everything is so cute, miniature and together looks very appealing. The shops in the west have a lot of work to do to reach the same levels of desirability.
