What are critical issues in Japan?

Of cource there are many critical issues in Japan. There are political issues, social issues, etc. As for political issues, I am always disappointed with Japanese politicians. Most of the Japanese leading politicians are only interested in whether or not their party can win in the next election, and after all, he or she can be a minister or not. According to today's news, the head of LDP, the Liberal Democratic Party, Mr.Tanigaki said they would take more offensive attitude against the ruling party, the Japan Democratic Party,and would go back into power. Is that what many people want?
Japn is facing a lot of urgent problems such as economic and finantial crisis, nation's security problems,educational problems, welfare problems, and so on. Before criticizing the government, or the ruling parties, discuss the problems more seriously, and propose good solusions, we do hope. The future of Japan and the Japanese people, and the future of the world depend on what and how they act.
