Prime Minister Naoto Kan survived a no-confidence motion Thursday after suddenly announcing his intention to resign once disaster-hit Tohoku is back on its feet and the crisis at the Fukushima No. 1 power plant is safely under control.

Kan's abrupt announcement barely prevented the ruling Democratic Party of Japan from falling apart, as dozens of members close to DPJ heavyweight and Kan rival Ichiro Ozawa refused to vote against Kan.

Kan survived easily by a vote of 293 to 152 in the 480-seat chamber, which included 15 DPJ and 15 opposition abstentions.
