The government Monday held a briefing session for embassy officials from nearly two dozen countries on the merits of a plan to release tritium-tainted water from the Fukushima No. 1 nuclear power plant into the ocean.

A session was held at the Foreign Ministry in Tokyo, and offered an update on the planned disposal of more than 1 million tons of water that have been treated and kept in tanks at the crippled complex, where storage space is quickly running out.

Releasing the water into the Pacific Ocean and evaporating it are both "feasible methods," the government explained, noting that there are precedents for the two approaches both within and outside of Japan.
