Chopsticks come with a number of rules attached to them and there are certain chopstick etiquettes that the Japanese follow.
Firstly, don’t tap the chopsticks against the bowls or plate. Also, don’t stick them straight in your bowl of rice or noodles. You should also be careful while picking up food with chopsticks. Don’t stab your food with them, the movement of picking up food should be smooth and gentle. Also, never chew on your chopsticks and also keep them back in the wrapper after finishing your meal.
