Japan does not know how Russia will handle the required rouble payments for its energy sold to "unfriendly" countries, finance minister Shunichi Suzuki said on Thursday.
"Currently, we're looking into the situation with relevant ministries as we don't quite understand what is (Russia's) intention and how they would do this," Suzuki said in a parliament session.
Suzuki said the government would closely monitor the "side effects" of the sanction measures on the Japanese economy and financial markets and continue to take appropriate steps in coordination with the Group of Seven (G7) and the international community.
The government will also coordinate with Japanese companies to collect information about the move, Chief Cabinet Secretary Hirokazu Matsuno told a Thursday news conference.
Japan accounted for 4.1% of Russia's crude oil exports and 7.2% of its natural gas exports in 2021.
