TOKYO (Reuters) - Two former Japanese prime ministers challenged incumbent Shinzo Abe's pro-nuclear power policy on Tuesday, with charismatic Junichiro Koizumi backing ex-premier Morihiro Hosokawa's bid to become Tokyo governor on a platform opposing atomic energy.
Hosokawa's candidacy could turn the local election into a referendum on Abe's energy policies and boost the anti-nuclear movement, which has lost momentum after a surge following the March 2011 Fukushima disaster, the world's worst nuclear accident in 25 years.
