Japanese Prime Minister Shigeru Ishiba addressed the situation on Monday, saying that Japan will "carefully monitor the developments and prepare to respond to any contingency."
The drills, which China described as a "stern warning" against Taiwan independence, included deployments of the aircraft carrier Liaoning and coast guard vessels.
Taiwan's defense ministry reported a record number of Chinese aircraft incursions, with 125 planes detected by Monday late afternoon. The United States expressed serious concern over the drills, while China maintained that the Taiwan issue is an internal matter.
