I bet somewhere in your area is a Japanese style resturant or shushi bar. Stop in and ask them if they know of anywhere that might carry what you are looking for. Look up "Japanese" in your phone book. If there is anything listed, give them a call and they might be able to help you. Maybe if worse comes to worse, you can find somewhere on the internet where you can order what you want. Hopefully, someone else will have an answer or a better idea.
