Japanese Prime Minister Shinzo Abe has described the launch as an “unprecedented” and a “most serious and grave” threat.
The missile flew over Hokkaido Island, broke into three pieces, before landing harmlessly into the Pacific Ocean, BBC reports.
Abe said he had a 40-minute phone call with the United States president Donald Trump and they agreed to call an emergency UN security council meeting.
According to Guardian, the missile is thought to be a new intermediate-range Hwasong-12, the same type North Korea threatened to launch toward the US military base in Guam.
Japan’s alert system warned people to seek shelter in a “strong structure or basement.”
