No this is not Sushi, it’s Sashimi (刺身), which is kind of the same, but without the rice. It’s raw fresh fish and reaaaaaaly delicous. There is also a version where the fish is still moving (from reflexes) while the Sashimi is served, its called  Ikizukuri. Definitly not something for everyone, but you can’t get fish fresher then this. But I wan’t able yet to try this … maybe I will get a chance. (Don’t judge me :p)
