The popular manga series "Oishinbo" came under fire again Monday after a character based on a real-life former mayor refers to Fukushima Prefecture in its latest issue as unlivable because of the radiation leaking from the ruined power plant there.

The Fukushima Prefectural Government fired back at the publisher the same day, saying no health problems have been reported as a result of the release of radioactive materials from the Fukushima No. 1 plant.

In a separate statement, the Osaka Prefectural Government took issue with the assertion, expressed by a character based on real-life medical expert Eisuke Matsui, that about 800 people living around an incinerator there have been affected by burning tsunami debris tainted with radiation from Tohoku.
