Abstract
In this paper I have made a comparative research of the social background and trends that support Japan-South Korea student's friendship. It turns out that both national groups were generally satisfied with their friendship although there was a difference in the process of mingling with their friends. In case of associating with friends, Japanese students tended to value the feeling side, while South Korea students tended to value their attributes and their shrewdness. In the process of forming friends, analysis showed that both national groups were influenced by their degree of school adjustment and their quality of family life, while school achievement (Japanese students) and an item that asked about Internet friends (South Korean students) had a passive effect.
