Next Japanese Prime Minister?

Who will the next Japanese Prime Minister be? Liberal Democratic Party becomes more and more chaotic internally. The party lost the Tokyo Metropolitan Election in 2009 against Democratic Party, the second biggest party. The member of LDP accuses of the Prime Minister, Taro Aso about the present situation.

Japanese senior people tend to say "Don't blame for someone else. Don't excuse. You should blame yourself and apologize to others." In politics, nobody does so. Especially, LDP blames the Prime Minister for losing LDP polls. Is it right?

In three years the Prime Minister of Japan has been changed three times. LDP chose one who is the most popular person at that time. Aso is one of them. He is in fact chosen by LDP! The people of Japan only think that LDP is no longer worth voting for. I say to LDP "Blame on you and wake up!" Is there an ideal leader to be the next Prime Minister of Japan?
