The Japanese government has pledged 47 billion yen (£303m) to contain leaks at the crippled Fukushima nuclear plant, a government spokesman has said.
It follows the detection of a serious leak from one of the storage tanks containing contaminated water on site.
"The contaminated water problem is getting more critical by the day, and the government felt it was essential to become involved to the greatest extent possible," Chief Cabinet Secretary Yoshihide Suga said.
He said that the funds would be used for a water containment wall and decontamination.
