The more troubles the LDP faces, the more it becomes rural-oriented for support, making it more detached from the views of the great majority of the people. This is a suicidal approach. If that doesn't change, the party will disappear. I believe Japanese politics will change, mostly from voters' demand for change. In Japan, people tend to criticize the political leadership without recognizing that these politicians are in power because the voters elected them.
Politicians do what they do in order to get elected.
This is a democracy. You can't just criticize the politicians who give voters what they want. In democracy, the voters basically get what they want. They have the ability to change the government, and I think they will. For the past 10 years since the collapse of the economic bubble, Japanese people have been uncertain about whether they really wanted change to occur.
