In the 17th century, the isolated Japan, most people had the same way thinking. In other word, they could help each other, and friendship among people used to be mutually sacrificing and interdependent. People helped each other for the sake of accomplishing their purpose. However, due to having no purpose, friendships of Japanese youth are now thinning. Second, the disappearance of leaders is another problem.
Leader is a person who tries to lead the group to their goal with hope.
Today, for the many Japanese youth who do not have hopes to live, the leader is regarded as unnecessary. These kinds of problems are noticed remarkably at the present day. Through Western influence on Japanese youth, the sense of values of the Japanese young people has changed. It is true that Japan has developed thanks to influence of the Western countries. For example, during the 1960s, Japan had a great alternative culture through Western influences.
