It is generally admitted that the adolescents build deeper friendships as they grow older, and they make deeper relationships with their own selves. But since 1980s, it has begun to be noticed that modern Japanese adolescents tend to have weaker forms of friendships. The previous researches have clarified some forms of their weak friendships. Okada found three forms of weak friendships of adolescents; 1) Crowd - they prefer to gather in crowds; 2) Careful - they take care not to hurt each other; 3) Avoiding - they avoid deep relationships with others. But their qualitative differences still remain unexplored. The purpose of this paper is to re-examine what each of these three forms of relationships means psychologically in terms of the adolescents' quest for their selves.
