Well yeah, sushi is the rice itself, while sashimi is the raw fish itself. If you have a mixture of both, it's still called it sushi. You can also have sushi with vegetables or fruits and no fish or meat. Your sushi can come with or without seaweed.

Korea has a similar dish called kimbap, which literally translates to "seaweed rice", so having something other than a roll wouldn't be kimbap anymore. Also, Korean kimbap uses a different recipe for the rice (usually sesame oil and salt), so it can't even be considered a special case of sushi (rice with vinegar and sugar).

I feel far too many people don't understand what sushi is, even if the consider it one of their favorite foods.
