Japanese fighter jets were scrambled to escort two Russian nuclear bombers flying towards the country's main island on Monday.
Two TU-95 aircraft, otherwise known as 'Russian Bear' bombers, skirted the islands of Hoshu and Hokkaido before flying back across the Sea of Japan.
The mission comes after America dispatched its own B-2 nuclear bomber over the Pacific Ocean on Saturday to show its 'commitment' to allies in the region, according to Daily Mail.
The stealth bomber, once of the most advanced aircraft ever built, took off from Whiteman Air Force Base in Missouri for a long-range training drill in the Pacific.
Japan said that neither of the Russian bombers ever entered its airspace.
