replying to an old post, but thought some people may want to know...you don't use wasabi with sushi. If you want more wasabi in your sushi, you ask the chef to prepare it with extra wasabi. You use wasabi yourself when eating sashimi. Don't smear it on the sashimi, but just place a bit on top, then dip the sashimi lightly in soy sauce.
