Close contacts between Japan and the rest of the world were created in the twentieth century. In the last forty years, business contacts between Japan and the West have become very important. Many foreign companies now have offices in Japan and Japanese businessmen do business around the world. Differences between Japanese and Western ways of doing business, however, often bewilder foreign businessmen and make doing business in Japan difficult for foreigners.
    The American businessman, for example, wants to start talking business immediately. He does not want to wait. The Japanese businessman, on the other hand, likes to arrive at decisions after giving them serious thought. Another thing foreign businessmen have difficulty in understanding is when a Japanese means "Yes" or "No". This is because of cultural differences between Japanese and Western society(社会), Which make it difficult for a Japanese to say "No" directly.
    In the USA, it is easy to say "No" to something one does not want to do. But in Japan, it is very difficult to say "No". To refuse an invitation or a request(请求) with "No" is felt to be impolite. It is thought to be selfish and unfriendly. So instead of saying "No" directly, the Japanese have developed many ways to avoid(避免) saying "No". These can help them avoid hurting other people's feelings. However, this often makes their ways of doing business rather difficult for foreigners to understand and follow.
