Proper way of eating common dishes

Rice Dishes:
Never pour soy sauce over white, cooked rice. While eating, lift the rice bowl towards your mouth with the chopsticks in the other hand to place food into your mouth.

Sushi:
Soy sauce is considered a precious condiment so do not waste it. Place what you can actually use on a platter and add sparingly if you need more.

Be cautious of adding too much wasabi sauce into your soy sauce. Some sushi pieces already contain wasabi and some are supposed to be eaten without it. You can request the chef not to include wasabi in your sushi if you do not have a preference for the spice. However, if you prefer a more pungent sushi, be careful to add only a small amount since some sushi chefs are sensitive about it.

Sushi is eaten with one single bite. Attempts to separate a piece into two, most often end in the destruction of the beautifully prepared sushi and an embarrassing moment for you. It is acceptable to use hands or chopsticks to eat sushi.

In case of nigiri-zushi, dip the piece into the soy sauce upside-down with the fish part ahead. A few kinds of nigiri-zushi, for example, marinated pieces, should not be dipped into soy sauce.

In case of gunkan-zushi, pour a small amount of soy sauce over it, rather than dipping it into the sauce.

Sashimi:
Place some wasabi on the sashimi piece then dip it in soy sauce. Do not use too much wasabi as this would overpower the taste of the raw fish and possibly offend the chef. Some types of sashimi are enjoyed with ground ginger rather than wasabi.

Miso Soup:
Drink the soup out of the bowl as if it were a cup, and fish out the solid food pieces with your chopsticks.

Noodles:
Lead the noodles with your chopsticks step by step into your mouth, while sucking them in with a controlled slurping sound. Try to imitate the slurping sound of people with you.

In case of noodle soups, keep the distance between the bowl and your mouth small in order to avoid splashing. If a ceramic spoon is provided, use it to drink the soup, otherwise, lift the bowl to your mouth in order to drink the soup.

Kare Raisu:
(and other dishes in which the rice is mixed with a sauce)
Kare Raisu (Japanese style curry rice) and other rice dishes, in which the rice is mixed with a sauce (for example, some domburi dishes) and may become a little bit difficult to eat with chopsticks, are often eaten with large spoons rather than chopsticks.

Big pieces of food:
Separate the piece with your chopsticks (this takes some exercise), or just bite off a piece and put the rest back onto your plate.
