Morihiro Hosokawa pledged Wednesday he would try to end Tokyo's dependence on nuclear power as he finally made his candidacy for governor official just a day before campaigning officially starts.

The 76-year-old former prime minister said he would set up a strategic panel of experts to explore basic energy policies to abolish nuclear power.

"In order to realize a Tokyo that is not dependent on nuclear energy, I would prompt the public and private sectors to generate renewable energy as well as to ask for cooperation from the residents of Tokyo to conserve energy," Hosokawa told a news conference, finally revealing his election pledges after two delays.
