SEOUL/TOKYO, May 29 (Reuters) - North Korea has notified Japan of a plan to launch a satellite between May 31 and June 11, a Japanese coast guard official said on Monday. North Korea informed the Japanese coast guard of the planned launch, the coast guard official told Reuters, confirming earlier reports by public broadcaster NHK and other Japanese media. The Japanese prime minister's office urged North Korea to refrain from the launch and said it would work closely with allies. "We strongly urge North Korea to refrain from launching," the prime minister's office said on Twitter, adding it would cooperate "with relevant countries such as the U.S. and South Korea". North Korean leader Kim Jong Un in May inspected a military satellite facility, North Korean state media KCNA reported.
