<p>An increase in cross-border movement of people has led to diverse contacts and exchanges among people. The number of foreign visitors to Japan is also increasing every year. The increase in the number of foreign visitors from East Asia is particularly remarkable. Although there has been diplomatic friction, such as recent issues of historical awareness, mutual exchange among East Asian countries has a long history. Even today, student exchange programs account for a certain percentage of international movements. However, little information on the current situation and practices of intercultural education has been shared. Therefore, in this special issue on the subject of international exchange in East Asia, focusing on the practices and research on intercultural education, we have attempted to investigate how research on intercultural education can contribute to the development of inter-regional cooperation in East Asia. From the contributed papers, it is apparent that international exchange in East Asia differs from that in Western countries historically and culturally, and through the similarities and differences, it has affected individuals’ way of thinking and growth and character formation. Each of the studies offers suggestions toward overcoming historical conflicts. It is hoped that the accumulation of these studies will substantially contribute to the mutual understanding among nations and the future development of international relations.</p>
