Gazprom Deputy Chairman Alexander Medvedev is in Tokyo for meetings with the heads of Japanese energy companies Mitsui, Mitsubishi and Tokyo Electric Power Co.
"The meeting considered the prospects for energy cooperation between Russia and Japan," the Russian energy company said in a statement. "In particular, special attention was paid to the issue of gas supplies to Japan as part of the Sakhalin II (liquefied natural gas) project and to potential participation in Japanese energy projects by Gazprom."
After March's 9.0-magnitude earthquake and tsunami, which severely damaged the country's energy sector, Japan took on more natural gas to make up for an energy deficit.
Gazprom said it delivered five additional shipments of LNG to Japan with a total volume of 15.5 trillion cubic feet in 2011. All of Japan's consumed natural gas comes in the form of LNG.
