Bummer. The vote of no confidence was set to pass, until Hatoyama decided he wanted to be a king-maker. Ichiro Ozawa, who an increasing number of Japanese feel should be the PM to deal with the current crisis, was betrayed by Hatoyama, who had promised Ozawa that his faction would vote for no confidence.
I don't know why anyone still listens to Hatoyama, who was one of the most ineffectual PMs that Japan had, in my opinion, until Kan came along. Good pedigree and tons of money count, I suppose.
Many people in Japan have said it is no time to fool around with politics when the country is in crisis. So? This particular government hasn't done much anyway, other than giving press conferences. People are still living in shelters, without enough running water or food. The government doesn't do anything about Fukushima I Nuke Plant; TEPCO does. Besides, this was the country that went on to hold nationwide local elections soon after the quake/tsunami and Fukushima I Nuke Plant accident when people were still very much shaken and not in the right frame of mind.
Getting rid of this Prime Minister and his cronies in his office and in the administration would have been a fresh start.
