mmmm.. sounds good. I agree a little with little_tippler though, they are extremely unhealthy considering the amount of fat and trans fat in them. But, then again, they are cookies basically... so... there you go.
I'm dying to find me some of these snacks though. I just don't know anyone that sells them around me. I'll have to look online I guess.
Here's a good site that rates all kinds of japanese snacks:
