Radiation levels continue to cause concern as plant operator's ability to deal with the situation is questioned.
The Japanese government will take prompt, comprehensive steps to clean up the wrecked Fukushima nuclear plant amid growing concerns about the plant operator's ability to handle it, the country's prime minister has said.
Shinzo Abe said on Monday that his government will step forward to take all necessary steps to handle the legacy of the March 2011 nuclear disaster.
He said the government will draw up a fundamental plan to do so "quickly."
Tokyo Electric Power Co, or Tepco, said at the weekend that radiation near a tank holding highly contaminated water at the plant had jumped 18-fold, to a level that could kill an exposed person in four hours.
Abe's cabinet is likely to discuss this week funding for the Fukushima clean-up after a series of revelations about leaks of radioactive water at the coastal plant, according to Tadamori Oshima, who heads the ruling Liberal Democratic Party's taskforce on post-disaster reconstruction.
