Traditional sushi originated as a preservation method in ancient Japan. Modern nigiri sushi emerged in 1820s Tokyo. Japanese sushi etiquette differs significantly from Western practices.
Sushi represents one of Japan's most famous culinary exports and carries deep cultural significance. The word sushi refers to vinegared rice, not raw fish as many people assume.
This technique called narezushi reached Japan around the 8th century. During the Muromachi period from 1336 to 1573, Japanese people began eating the rice along with the fish. The modern sushi style emerged in Tokyo during the 1820s. The introduction of sushi to the United States in the 1960s and 1970s eventually made it a global phenomenon.
Traditional sushi etiquette differs significantly from Western practices. First, eating sushi with your hands is not only acceptable but traditional. Never rub disposable chopsticks together, as this insults the restaurant by suggesting they provide cheap, splintery chopsticks. When dipping nigiri in soy sauce, turn it sideways and dip only the fish side.
Ordering omakase lets the chef choose your meal based on the best ingredients available that day. At high end sushi restaurants, omakase represents the only way to experience the chef's full artistry. The chef serves 15 to 20 pieces in a specific sequence designed to build flavors progressively. Top sushi restaurants in Japan charge $300 to $600 per person for omakase.
Traditional sushi chef training in Japan follows a rigid apprenticeship system lasting 10 years or more. Apprentices start by cleaning and performing menial tasks. Only after mastering all aspects does an apprentice become a full sushi chef. Modern sushi schools offer faster training, but traditional chefs view these graduates skeptically.
Kaiten sushi, or conveyor belt sushi, provides an affordable alternative to high end sushi restaurants. Yoshiaki Shiraishi invented the concept in Osaka in 1958. Plate colors indicate prices, typically ranging from 100 to 500 yen. Many Japanese people eat at conveyor belt sushi frequently while reserving high end sushi restaurants for special occasions.
