TEPCO's President Masataka Shimizu hospitalized

The president of the embattled utility that owns the crippled Fukushima Daiichi nuclear plant has been hospitalized due to "fatigue and stress," the company said Wednesday.

Tokyo Electric Power Co. President Masataka Shimizu was hospitalized Tuesday. The company has not released further details about his condition, according to CNN.

On Monday, TEPCO said Shimizu fell sick during the crisis and took several days off from the joint task force that had been set up by the government and the company.

The Mainichi daily had quoted a senior TEPCO official as saying Shimizu had been so sick that he had stayed "mostly in bed" in a separate room in the building where the task force was meeting.

Shimizu has not appeared in public since attending a press conference on March 13, leading to criticism from local media, Hindustan Times reports.
