The rice is seasoned using rice vinegar, sugar, and salt; and done to compliment fish or whatever is draped over it. Dunking it into a bowl of soy/wasabi negates the flavors of both. Typically if wasabi is served, it's done as a tiny smear between fish and rice, and the top of the fish will be lightly painted with what ever soy-based sauce the chef chooses. This way the flavor of the rice and it's seasonings is preserved.
