The wife of Democratic Party of Japan kingpin Ichiro Ozawa has divorced him, saying he fled Tokyo soon after the Fukushima nuclear crisis started last March out of fear of radiation, according to the weekly Shukan Bunshun, citing a letter it says she wrote to his supporters in November.

"Facing unprecedented catastrophe, politicians must be the first to stand up, but in fact Ozawa ran away with his secretaries because of fear of radiation," states the letter allegedly by Kazuko Ozawa.

The Shukan Bunshun website has an image of the first page of the 11-page handwritten letter, large and clear enough for its words to be read. The print magazine also has photos of the letter and its entire content in printed form, with a few names blacked out.
