In many Asian countries, people eat with chopsticks. However, while in some of them, like China and Korea, people use other cutlery such as spoons, Japan is a unique in that people use chopsticks for eating almost all food from rice, meat, vegetables to soup.
Over many years, an etiquette around use of chopsticks has developed in Japan. Many of them are not well known outside of the country, but they are considered the basic manners of Japanese cuisine.
Here is some of the taboos that you may want to avoid when you have meals with Japanese people.
2. Lick the chopsticks (Neburi-hashi)
5 things that you should not do in Japan when eating.
1. Stick the chopsticks in the middle of the bowl. (Tate-hashi or standing chopsticks)
In buddhist funeral, we place a bowl of rice with the chopsticks sticking in the middle as an offering to the dead. It is thought not to be appropriate that you do this as it implies someone's death.
3. Move a plate with using the chopsticks (Yose-hashi)
Also, dragging a plate on the table is thought to be bad. When you want to move the plate, you take it up and place it without dragging.
4. Point out someone with the chopsticks. (Sashi-hashi, pointing chopsticks)
You are not supposed to use chopsticks to point people or things.
I used to do this when I was little and I was often scolded by my mom... When you give food to your friend, you place it on the plate and a friend pick it up from it.
