The last time Russian military aircraft circled Japan was in 2019, a ministry official told AFP on Friday, but that incident involved bombers that did enter the nation’s airspace.
Earlier this week, Russian and Chinese warships began joint drills in the Sea of Japan.
The drills are part of a major naval exercise that Russian President Vladimir Putin has described as the largest of its kind in three decades.
Russia and China have ramped up military cooperation in recent years, with both railing against what they see as the US domination of global affairs.
They declared a “no limits” partnership shortly before Moscow launched its offensive in Ukraine in 2022.
Since the start of the Ukraine conflict, relations have deteriorated sharply between Japan and Russia, which both claim the Kuril Islands – known in Japan as the Northern Territories.
The Soviet Union seized the strategically located volcanic archipelago north of Hokkaido in the final days of World War II, and has maintained a military presence there ever since.
