Sushi is not exactly raw... Sashimi is. I eat Sashimi, Sushi and have eaten Ceviche (South American) and Poké (Hawaiian but i believe of Japanese origin)
Ceviche is the best tasting dish with Red Chilli. It's literally gets cooked in lime juice. But note that it's the best quality of cut of fish goes into these... Not exactly the type our guy demonstrated recently.
