Japan, which counts Russia as its fifth-biggest supplier of crude oil, is in discussions with the United States and European countries about possibly banning Russian oil imports, Kyodo News reported on Monday.
The report comes after U.S. Secretary of State Antony Blinken said on Sunday the U.S. and its European allies were exploring the possibility.
Asked about a potential embargo on Russian oil imports, Japanese Chief Cabinet Secretary Hirokazu Matsuno declined to comment on the country's communication with the U.S.
Russia accounted for 3.63% of Japan's imports of crude oil last year.
While sanctions imposed on Russia are not expected to directly affect Japan's ability to ensure a stable supply of liquefied natural gas (LNG), they could indirectly affect energy-related projects, Industry Minister Koichi Hagiuda said.
"We will closely monitor (developments)," he said in parliament, adding that Japan would act appropriately in step with the Group of Seven.
The Japanese government and companies own stakes in oil and LNG projects in Russia, including two on Sakhalin Island from which partners Exxon Mobil Corp. and Shell PLC have announced they will exit.
