Japan Maritime Self-Defense Force (JMSDF) personnel, wearing protective suits, operate on JMSDF auxiliary multi-purpose support ship Hiuchi near the Tokyo Electric Power Co.'s Fukushima Daiichi Nuclear Power Plant in Fukushima Prefecture, northeastern Japan, in this photo taken April 5 and released by Japan Maritime Self-Defense Force April 6, 2011. Japan stopped highly radioactive water leaking into the sea on Wednesday from the crippled nuclear plant and acknowledged it could have given more information to neighbouring countries about contamination in the ocean. Nuclear experts said the damaged reactors were far from being under control almost a month after they were hit by a massive earthquake and tsunami on March 11.[
