The weapons were launched from South Pyongan province in an easterly course over the ocean, Seoul's Joint Chiefs of Workers acknowledged in an announcement, with out specifying the model of instrument enthusiastic.
North Korea's last launch of a ballistic missile came Oct 2, when it fired from an underwater platform a new type of weapon created to be deployed on a submarine, which had an estimated range of about 1,900km.
Japan's Defense Ministry says North Korea launched a ballistic missile on Thursday afternoon.
Talks aimed at denuclearisation have stalled, although there were signs that Pyongyang and Washington could hold a third summit in the future.
The North's latest launch follows statements of displeasure over the slow pace of nuclear negotiations with the United States and demands the Trump administration ease sanctions on Pyongyang.
"The U.S.is now more desperately resorting to the hostile policy towards the DPRK, misjudging the patience and tolerance of the DPRK", he said, using the acronym for the North's official name, the Democratic People's Republic of Korea.
He described South Korean-built facilities there as "a hotchpotch with no national character at all" and "like makeshift tents in a disaster-stricken area or isolation wards", ordering their removal, Pyongyang's official KCNA news agency reported last week. Both sides offered a very different picture of events - Pyongyang accusing Washington of lacking flexibility, but the State Department said the U.S. "brought creative ideas and had good discussion with its DPRK counterparts", using the formal acronym for North Korea.
Kim's message came amid strained ties between the two Koreas amid a lack of progress in a US -led effort to rid North Korea of its nuclear weapons program.
PM commends Trump on death of ISIS leader
The death of Baghdadi is a severe blow to Islamic State, which has been in disarray and has no declared successor as leader yet. The Al-Qaeda leader was killed after a USA operation in Pakistan, which was carried out under President Barack Obama .
Talks between North Korean and USA officials broke down in Stockholm earlier this month.
Earlier this month, the North test-fired an underwater-launched ballistic missile for the first time in three years.
It also claims to have a nuclear bomb it can mount it on a missile.
Since the breakdown of the summit between North Korean leader Kim and US President Donald Trump in February, however, the cross-border ties have remained at a standstill with Pyongyang often complaining that Seoul is not active enough to move their relations forward mindful of global sanctions imposed against it.
After about an eight-month lull in direct nuclear dealings, the USA and North Korea held their first direct nuclear negotiations in Stockholm in early October, with the two sides disagreeing about what was on the table and showing how far apart they are.
The launches occurred hours after South Korea said that Kim had sent a message of condolence to President Moon Jae-in over the death of his 92-year-old mother earlier this week.
The two leaders met three times previous year and struck a set of deals aimed at easing animosities and boosting exchanges.
"Kim's year-end threat is as much a deadline for economic progress as it is a diplomatic ultimatum", Easley said.
