This paper discusses similarities and differences in negotiation styles between Americans and Japanese based on the results of questionnaires administered to 96 students in the United States and 102 students in Japan. Both in negotiations with a family member or a friend and in a business context, universal factors and those specific to American and Japanese cultures are identified. Although the essence of negotiation is universal, Americans and Japanese need to acquire different abilities in order to foster give-and-take relationships that will benefit both parties. It is essential for Americans to acquire the abilities: to listen attentively to what the other person says, and display a willingness to compromise by controlling emotions. On the other hand, it is indispensable for Japanese to acquire the abilities: to utilize logic and reasoning, and help others recognize points of disagreement by expressing their opinions clearly.
