Question: do you eat nigiri with chopsticks?
Answer: It is OK to eat nigiri-zushi (sushi) with your hands. Sashimi is only to be eaten with your chopsticks. Pick up the nigiri-zushi and dip the fish (neta) into your shoyu, not the rice (which will soak up too much shoyu). ... It's not up to you to have proper sushi etiquette if it's physically impossible.
