The missiles were launched from the Tongchang-ri region near the North's border with China and flew about 1,000 kilometers (620 miles), MANA correspondent reported cited by South Korean military officials.
No reports of damage to shipping or aircraft had been received.
North Korea test fired a new type of missile, known as the Pukguksong-2, into the sea early last month, and has said it will continue to launch new strategic weapons. The missile did not reach Japanese territorial waters.
A fully developed inter-continental ballistic missile could threaten the continental United States, which is about 9,000 kilometers (5,500 miles) from North Korea, reports Reuters.
During a joint meeting with U.S. President Donald Trump last month, Abe said: “North Korea’s most recent missile launch is absolutely intolerable. North Korea must fully comply with the relevant United Nations Security Council resolutions.”
Trump said: “I just want everybody to understand and fully know that the United States of America stands behind Japan, its great ally, 100 percent.”
North Korea conducted a number of nuclear and missile tests last year, in contravention of U.N. resolutions. The tests have prompted the U.S. and South Korea to agree to deploy a Terminal High Altitude Area Defense (THAAD) anti-missile battery in South Korea later this year.
