The capital injection will hand control of Tepco to the government and brings total state support for the company to at least 3.5 trillion yen since reactor meltdowns at the Fukushima Daiichi plant triggered by last year's earthquake and tsunami.

Shareholders at the utility's annual general meeting also rejected a proposal to scrap all seven reactors at Tepco's Kashiwazaki-Kariwa plant, the world's biggest nuclear facility, on the Sea of Japan coast.

The proposal called for replacing the plant with a new fuel-efficient, gas-fired combined cycle power station at the site.

The eventual cost of the Fukushima nuclear disaster, including compensation and cleanups, has been estimated at more than $100 billion.
