Foreign ministers from Japan and Russia met in Tokyo for the bilateral "two-plus-two" talks, and were also joined by their respective defense ministers, on Monday.
The one-day meeting comes as the two sides focus on confidence-building measures in both defense and security. The Tokyo talks are not expected to end a decades-long territorial dispute, which has blocked them from forging a peace treaty since the end of World War Two.
Moscow earlier denounced the United States' global missile defense system deployment in the Asia-Pacific, labelling it "a damage of regional strategic balance". Russia also expressed concerns towards Japan's move to bring in the THAAD system.
Foreign ministers of the two nations also laid out a detailed plan for Japanese Prime Minister Shinzo Abe's visit to Russia scheduled in April.
