A large part of the new funding announced by the Japanese government will go towards freezing the ground around the Fukushima nuclear plant to contain the leak, according to local press reports.
The process, which is expected to cost 32 billion yen, will involve burying vertical pipes in the ground around the plant and pumping refrigerant through them.
Around 15 billion yen will go towards treating the contaminated water being stored at the plant.
