If you plan to travel to japan.you need to learn some rules for eating.They aren't difficult to learn.If you eat something with the Japanese,you can hear them say "itadaki-masu".This is to show thanks for the food they eat and to the person who made the food.You can also hear the Japanese say "gochiso-sama" when they finish eating.This is also to show thanks and to say the dishes are good.They start to eat only when everybody is seated at the table.They usually have a conversation at meals,but they don't speak while they are eating.Remember the rules and they can help you.You should also remember that it's good to eat every dish.
Hope you will like,good luck!
