North Korea fired a ballistic missile that flew 430 miles on Sunday local time from a region near its west coast, South Korea's military said. Japan said the projectile flew for 30 minutes and dropped in the sea between the North's east coast and Japan.
The missile launch follows a series of other projectiles fired since President Trump took office in January.
Japan responded immediately to the incident, claiming the firing was violation of U.N. resolutions. Prime Minister Shinzo Abe told reporters, "North Korea's repeated missile launches are a grave threat to our country and a clear violation of UN resolutions,"
He added that Japan will stay in close contact with the U.S. and South Korea.
The missile test marked the beginning of a new era for South Korea. The firing was the first under newly-elected liberal President Moon Jae-in, who took office in South Korea on Wednesday following the impeachment of former President Park Geun-hye on corruption charges.
In response, he called an emergency National Security Council meeting, the presidential Blue House noted.
The missile's launch surfaced just about two weeks after a ballistic missile test failed on April 29, which blew up over land in North Korean territory.
