According to the Yonhap New agency, the South Korean military detected a missile launch conducted by North Korea on Monday.
Seoul's Joint Chief of Staff (JCS) said that the launch was conducted from the area near the North Korean city of Wonsan that is located on the country's east coast. The military added that the projectile had covered some 450 kilometers (280 miles) before falling into the Sea of Japan.
Japanese Chief Cabinet Secretary Yoshihide Suga lodged a protest over the launch, saying that the missile fell in Japan’s exclusive economic zone.
“The missile, which was fired from the eastern coast of North Korea, has fallen in the exclusive economic zone of Japan. It is necessary to ensure the security of Japanese ships and planes,” Suga said at a press conference on Monday.
In the wake of the launch, South Korean President Moon Jae-in ordered to convene the meeting of the country's national security council.
"The United States government is aware. The president [Donald Trump] has been briefed," a spokesperson told reporters.
Tensions around North Korea's activities with both nuclear and non-nuclear weapons have drastically escalated in recent months, after Pyongyang conducted a number of nuclear tests and ballistic missile launches in violation of the UN Security Council's resolutions.
US media reported earlier that Trump might order a strike against North Korea in light of the latter's military activities.
On Saturday, media reports emerged saying that the US aircraft carrier Nimitz was sent to the Asia-Pacific region to join two other American strike groups that had been already deployed near the shores of the Korean Peninsula.
US Defense Secretary James Mattis said on Sunday that possible war with North Korea would be a disaster affecting all the nearby countries in the region, including China and Russia. He stressed that the fact that Pyongyang possesses "hundreds of artillery cannons and rocket launchers" within range of South Korean capital of Seoul would make the potential conflict particularly dangerous.
The most recent launch of North Korean ballistic missile took place on May 21. The ground-to-ground missile reportedly flew some 500 kilometers (310 miles) before falling into the Sea of Japan short of reaching Japan’s exclusive economic zone.
