New trade and industry minister Yoichi Miyazawa paid a visit to the disaster-hit Fukushima No. 1 nuclear plant over the weekend, his first since replacing Yuko Obuchi, who resigned in October over a funding scandal.

Miyazawa visited the wrecked plant on Saturday before going to Kagoshima Prefecture to push for the restart of idled reactors there, apparently to fend off criticism that he places greater importance on promoting restarts than dealing with the societal fallout from the triple meltdown in Fukushima.

"There are difficult issues, but we see things proceeding steadily so far," the economy, trade and industry minister said, referring to efforts to scrap the stricken reactors and deal with the massive amount of radioactive water accumulating at the plant.
