Dining Etiquette's of Japan
First thing first every Japanese meal starts with the word "itadakimasu", it is a very important phrase used by the Japanese before starting the meal. By using this phrase the person who is having a meal shows his/her gratitude towards the person who prepared the meal. The phrase "ithadankimasu" means "thank you for the food". the traditional Japanese meal is taken on seating the mat called tatami. Indian prime minister Mr Narendra Modi also had a meal with Japanese prime minister Mr Shinzō Abe seating on the tatami.
There are also certain rules of chopsticks that one should follow while having a meal. It is believed that one should never ever rub chopsticks against each other to avoid splinters because it shows the impression that the quality of chopsticks is not good.
Putting chopsticks upright in the bowl is considered as very rude because in Buddhism when a person dies a bowl of rice offered to the dead person by keeping the chopsticks upright. The Japanese believe that keeping chopsticks upright on the bowl act as a connector between the world and afterlife, so doing this to a living person is considered as rude. And you should also aware of not share food with chopsticks this is also considered very rude in Japan.
Japanese have a unique way to enjoy the meal and also to show how much they love food which really motivates to the chef. Slurping the food is considered a complementing to the food and the chef, doing so it also cools down the food and enhances the flavours. And talking to others while having a meal is also considered rude so be conscious of that
The other most important thing in Japanese eating etiquette comes while having drinks. it totally depends on with whom you are having drinks. you should not serve your glass with your own, you have to wait until some other person serves. always the Japanese start drinking by saying the word "kampai" which is similar to the English word "cheers"
Another most important thing to remember is never ever to give a tip to a Japanese waiter/waitress. Tipping is considered very insulting and rude behaviour.
