"Japan believes that full utilisation of written-off nuclear submarines, tough control of nuclear materials are necessary. Especially in the light of the threat of terrorism. Guided by these considerations, Japan develops cooperation with Russia in this field", the Japanese ambassador said.
Projects to back up the utilisation of Russian submarines are floating in the Japanese parliament, he said.
"I'm sure that cooperation with Russia in this sphere must be developed", Issei Nikomura said.
He voiced the hope that the process of submarines utilisation will be over by 2010.
