Since the beginning of 2022, North Korea has conducted over 30 robotic tests.
They have intensified during the war in Ukraine.
Today's robotic firings are said to have taken place from the Sunan area of Pyongyang at 6pm on Wednesday evening local time.
North Korea's international airport is located in Sunan.
From there, North Korea has regularly conducted robot tests, reports American NK News, which specializes in monitoring North Korea.
The short-range robots on Wednesday flew about 360 kilometers at a maximum altitude of 30 kilometers and at top speeds of about Mach 6 (122.5 kilometers per minute), according to South Korea's military command.
This is North Korea's second robot test in a week.
On Sunday, South Korea's military said North Korea fired a short-range ballistic missile from the country's northern region of Taechon.
It too crashed into the Sea of Japan.
"Deepening North Korea's isolation"
"Such provocative actions by North Korea further strengthen the South Korea-US alliance's deterrence and response capabilities, and deepen North Korea's isolation from the international community," commented the JCS military command.
The robot tests were conducted the day before US President Kamala Harris plans to visit South Korea's capital Seoul and the demilitarized zone (DMZ) between South and North Korea, reports South Korea's main news agency Yonhap.

On Wednesday, US Vice President Kamala Harris was aboard the USS Howard at the Yokosuka naval base south of Tokyo.
At the same time, a large naval exercise is taking place in the Sea of Japan in which both South Korea and the United States participate.
It began on Monday and is the first allied exercise in five years near the Korean Peninsula, according to Yonhap.
The United States participates, among other things, with the Ronald Reagan aircraft carrier group, a group with a central role in the US Navy.
The exercise began Monday and is the first allied exercise in five years near the Korean Peninsula, according to Yonhap.

South Korea fears new nuclear test
In recent weeks, there have been reports that North Korea is preparing a test explosion of nuclear weapons.
A nuclear test could take place within a month, according to South Korea.
South Korea's National Intelligence Service (NIS) briefed South Korean parliamentarians on the Intelligence Committee in a closed-door meeting on Wednesday, NK News said.
North Korea has carried out six test explosions of nuclear weapons, most recently in 2017.
