TOKYO, Aug 22 ― North Korea has informed Japan it plans to launch a satellite in the coming days, the Japanese government said yesterday, less than three months after a failed effort saw a military satellite plunge into the sea.

The office of Prime Minister Fumio Kishida said in a statement that Pyongyang had informed Japan of the planned launch, adding he had instructed his government to work with the United States, South Korea and other nations to urge its cancellation.

The Japan Coast Guard said the "satellite rocket launch” would take place between August 24 and 31, with three designated danger areas: the Yellow Sea, East China Sea and waters east of the Philippines' Luzon island.

In May, Pyongyang launched what it described as its first military reconnaissance satellite, but the rocket carrying it plunged into the sea minutes after takeoff.

North Korea said it had developed the spy satellite as a necessary counterbalance to the growing US military presence in the region.

Meanwhile, North Korea's state news agency condemned "the aggressive character” of US-South Korea military drills that kicked off on Monday.

In a Tuesday commentary, KCNA warned that if the drills involve a "nuclear provocation,” the possibility "of a thermonuclear war on the Korean peninsula will become more realistic.”

The United States, South Korea, and Japan condemned the North's satellite launch in May as a violation of United Nations resolutions prohibiting the nuclear-armed state from using ballistic missile technology.

Analysts have said there is significant technological overlap between the development of intercontinental ballistic missiles and space launch capabilities.

North Korean leader Kim Jong-un has made the development of a military spy satellite a top priority.

South Korea's spy agency told lawmakers last week that Pyongyang could launch a reconnaissance satellite in late August or early September, the Yonhap news agency reported.

The launch is meant to happen ahead of the 75th anniversary of the regime's founding on September 9, according to Yonhap.

The crash of the satellite in May sparked a complex, 36-day South Korean salvage operation involving a fleet of naval rescue ships, mine sweepers and deep-sea divers.

The retrieved parts of the rocket and the satellite were analysed by experts in South Korea and the United States.

South Korea's defence ministry subsequently said the satellite had no military utility. ― AFP
