Intercultural understanding can make a great contribution to international business activities in such fields as international marketing, consumer behavior, organizational behavior, intercultural management, intercultural communication with foreign workers. Although business world has been interested in matters of culture, but such interest has been regarded as minor and been relegated to industrial anthropology. However, there are many issues to be considered and developed from the perspective of education for international understanding. We find a growing number of culture specialists playing a greater role in the business world, and corporate culture movement is but one example. At the same time we can find a difference between managers on the one hand and culture specialists on the other. Many managers demand quick and simple solutions and prefer to take actions instead of investing in time consuming researches and sensitive approaches. In addition, many managers tend to regard cultural approach simply less expensive, leaving behind fundamental issues. In some cases, some managers expect greater ideological control from cultural approach. When the interests of the employees and those of the employers are in conflict, or when the interests of the people of other cultures and those of the business are in conflict, a serious question can be raised not only for culture specialists employed in the business world, but also for education for international understanding. In a sense this is a predicament common to the use of knowledge and understanding on those who are in socially weak position, and may constitute a serious dilemma for education for international understanding. Education for international understanding tells us that knowledge and understanding of other culture should not be used only for maximization of profit or greater control by business organizations. It is the task of specialists of education for international understanding to help employers and employees understand the social and environmental impacts and implications of their labor, business activities and decisions, and make greater efforts for sustainable development.
