“There are no other options,” he said.
“There is no fact that the method of disposal of contaminated water has been decided. The government would like to make a decision after making thorough discussion,” he said.
Last year, Japan acknowledged the first death associated with radiation exposure during cleanup work at Fukushima.
Nearby South Korea has previously expressed concerns that Japan might resort to dumping.
In August, South Korea’s government minister for environmental affairs, Kwon Se-jung, met with Tomofumi Nishinaga, head of economic affairs at the Japanese Embassy in Seoul, to discuss any potential plan to release wastewater into the ocean.
“The South Korean government is well aware of the impact of the treatment of the contaminated water from the Fukushima nuclear power plant on the health and safety of the people of both countries, and to the entire nation,” said a South Korean ministry press release.
Kwon suggested that the two countries work together to find ways to ensure that the treatment of contaminated water does not affect ocean health — or the health and safety of Japan’s neighbors.
