Japanese Sushi

Sushi is perhaps the most famous Japanese food in the world. In Japanese cuisine, sushi indicates dishes that use sushi rice, which is seasoned with a sweet vinegar mixture. Since Japan is surrounded by ocean, seafood has always been widely consumed as well as rice. So, the combination of raw fish and rice, sushi, naturally became a popular food in Japan. Originally, raw fish was fermented in salt to preserve it and eaten with seasoned rice. That's the origin of sushi. Even though there is sushi that doesn't include sashimi, raw fish and rice are the main ingredients of sushi.
