You cannot do that sort of thing in Japan. Because the university community is a microcosm of the Japanese community, the rules for entrance must have society's consent. Both the rules for entering a community and, as I shall discuss next, the rules for leaving it always require the tacit approval of all members of the community. The Japanese community does not allow people to wipe the slate clean and start over. The only officially sanctioned way to exit is to die.
Japan has one of the world's highest suicide rates.
Last year, because of the recession, reportedly there were some 24,000 suicides, about 2,000 more than the preceding year. People commit suicide because they cannot meet their obligations. They do not have money, so they cannot repay their loans. They cannot do everything they would like to for their families. Fundamentally, all members of the Japanese community are equal.
