Japan is looking at the possibility of having its sixth prime minister in three years. Naoto Kan, in office for just three months, is fighting a challenge from Ichiro Ozawa, a long-time powerbroker in the Democratic Party of Japan. The rivalry threatens to rip apart the party. Jeff Kingston, of Temple University, Japan Campus, predicts that the Democrats will pay a heavy price if they choose Ozawa. "Electing him basically would be a disaster for the party because on a four-to-one margin the public favors Kan," Kingston said. "The Japanese people are fed up with this [Ozawa's] style politics. And if the politicians who owe Ozawa do give him the backing and hand him the premiership I think the voters will never forgive the DPJ."
