According to the Kyodo news agency, such an assumption was made on the basis of the analysis of the trajectory of the missile's flight. There is a high probability that the missile launch was carried out at a steep trajectory, and it means that the missile flew at a high altitude, the media outlet said.
The maximum flight altitude of the North Korean missile, launched earlier on Sunday, amounted to over 1,000 kilometers (621 miles), the media outlet said earlier citing government sources.
Japanese Chief Cabinet Secretary Yoshihide Suga said that the missile presumably flew for 30 minutes not reaching the Japanese exclusive economic zone.
Following the launch, the Japanese and South Korean governments convened meetings of national security councils.
