As different countries have their own culture, table manners also vary among countries.
くにが ちがえば ぶんかが ちがうように、テーブルマナーも ちがいます。
In Japan, people slurp noodles such as ramen, buckwheat noodles (soba) and udon. This is not bad manners that you have to be ashamed of. Rather, some people feel that things taste better when they are slurping.
Food that you can slurp without being ashamed of or annoying anyone, however, is only noodles such as ramen, soba and udon even in Japan. It’s not good manners at all to have a miso soup with a loud noise.
Furthermore, there are a lot of manners regarding the ways of using chopsticks in Japan. Here, I will tell you a couple of taboos in using chopsticks that you might have already done without knowing them.
Do not stab your food with your chopsticks as if they are a fork.
Do not lick your chopsticks’ tips.
Do not use your chopsticks to pull your bowl/plate toward you.
There are many more dos and don’ts in using chopsticks. Even most Japanese may not know such detailed etiquette, so they would be really shocked when they see you as a foreigner using your chopsticks in a very proper and elegant way. I’ve provided a link in which explains more about the taboos in English. Let’s become a master chopstick user!!
Chopsticks are a perfect souvenir for their price and size, so they are popular among tourists from different countries, particularly those who have western backgrounds. It may be much appreciated if you could tell your friends about good chopstick etiquette when you present your choice of chopsticks to them.
