North Korea Fires Ballistic Missile, Says South Korea's Military

South Korea's military said North Korea launched a short-range ballistic missile from the Wonsan area at about 5pm.

"Our military detected a short-range ballistic missile launched from the Wonsan area of North Korea at around 5pm," South Korea's Joint Chiefs of Staff (JCS) said in a message to news organisations.

The JCS said earlier the missile was launched towards the East Sea, referring to the body of water also known as the Sea of Japan.

Japan's defence ministry also posted on X that "something that may be a ballistic missile has been launched from North Korea". A separate post shortly afterwards said "there is no longer any impact on the areas around Japan".

"Seoul has strengthened surveillance and maintained readiness for possible additional launches while sharing information with its security allies – the US and Japan," the JCS said.

'New militarism'

Japan's defence minister Shinjiro Koizumi said earlier this week that Japan's military needs to be boosted with a "sense of urgency and crisis", as a new government assessment warned of growing threats from China, Russia and North Korea.

In a statement carried by North Korean state media on Wednesday, Kim Yo Jong – the powerful sister of leader Kim Jong Un – said Pyongyang's "leadership will set up additional military options which are obviously due to Japan's transformation".

Japan's defence ministry declined to comment directly on Kim Yo Jong's remarks but said the country's defence capabilities "remain bare minimum" and "are not meant to threaten other countries". "Ours isn't the defence meant to wage wars, but to prevent new wars, strictly kept to self-defence and within the scope of our (pacifist) Constitution and international laws," it said.

Tokyo raised its military expenditure by 9.7% to US$62.2 billion in 2025 – equivalent to 1.4% of GDP, its highest share since 1958. China, a key ally of North Korea, has also recently expressed alarm at what it sees as "new militarism" by Japan.

North Korea has repeatedly declared itself an "irreversible" nuclear state since leader Kim Jong Un's 2019 summit with US president Donald Trump collapsed over the scope of denuclearisation and sanctions relief. Analysts say Pyongyang has also deepened economic and military ties with Russia, supplying troops and munitions for Moscow's war in Ukraine in exchange for financial support, food, energy and military technology. It has repeatedly branded Seoul its "most hostile" enemy.

South Korea's dovish president Lee Jae Myung has reversed his hawkish predecessor's stance since taking power in June 2025, offering nuclear-armed Pyongyang talks without preconditions. North Korea's leadership has yet to respond. The two Koreas remain technically at war, as their 1950-1953 conflict ended with an armistice rather than a peace treaty.
