The first culture difference that many Japanese find in America is their greeting customs. Although the greeting is one of the simplest human communications, both countries have different methods of greeting each other. Three differences include introduction, self-introduction, and departure. In addition, the main reason for the difference is that Americans use verbal greetings and the Japanese use nonverbal greetings.
First, the order of introduction in the U.S. is the reverse of the Japanese way. In America, generally elderly people are introduced first. For example, one of my friends invited me to his house, and he introduced his father first, then his mother, his older brother, and his young sister. After that he introduced me to his family. In contrast, the traditional rule is the opposite in Japan. In other words, young people have to be introduced first in Japan. This rule is the sort of manner in Japan, and the people who do not follow this regulation are considered rude.
The methodology of self-introduction varies between America and Japan. Americans prefer the inductive method that brings out general idea from concrete; therefore, they are apt to talk about their privacy first. Almost all American students talk about their family or themselves. For instance, a woman who is a student at St. Cloud State University talked about her Iowa State and her family who are farmers. Then she said that "The crops are mainly potatoes, and my family likes potatoes." Finally, she said that her family is a German line. In contrast, Japanese prefer a deductive method. In other words, Japanese people are likely to talk about where they belong to. For example, the typical Japanese person first talks about his university or his major, then what kind of club they belong to. Finally they usually talk about hobbies or an event that happened...
