The bombers were escorted by Su-30SM fighter jets, the ministry said, adding that the mission was carried out in strict compliance with international airspace regulations.
"Two long-range strategic missile carriers Tu-95MS conducted a scheduled flight in the airspace over the neutral waters of the Sea of Japan. The flight lasted around 10 hours," the ministry said.
Russian long-range pilots fly routinely over neutral waters of the Arctic, North Atlantic, Black and Caspian seas, and the Pacific Ocean, the ministry said.
