North Korea has launched what appears to be a missile headed towards the northern end of Japan at around 5:58 a.m. local time, according to Japanese government officials.
Japan's NHK News reported that the missile passed over Japan and warned people in northern Japan to take necessary precautions.
Although three missiles were fired, according to Japanese officials, it was not entirely clear if all of them were headed towards the same trajectory. NHK also reported that a missile broke off into three pieces before splashing down into the Pacific Ocean.
South Korean military officials have also confirmed reports of the missile launch and said that it flew for about 1677 miles.
During the tense moment, multiple prefectures in Japan were reportedly put on alert.
"We'll take utmost efforts to protect the public," Japanese Prime Minister Shinzō Abe said, shortly following the launch.
The latest act of provocation from North Korea comes amid a spate of questionable moves, despite regional leaders, including Russia, denouncing North Korea's nuclear ambitions.
South Korean President Moon Jae-in recently called for his county to prepare to "immediately switch to offensive operations" if the North makes a "provocation that crosses the line," NK News reported.
On September 1, 1998, North Korea fired a missile towards Japan's airspace, offering no explanation for the incident.
