New York Times: Four years after retiring from politics, Japan’s former prime minister Junichiro Koizumi announced Tuesday that he opposes nuclear power.

Koizumi won two elections, in 2002 and 2005, and continues to be popular, but whether his renouncement of his former pronuclear stance will reignite the popular opposition movement remains to be seen.
