North Korea has fired around 150 ballistic missiles at Ukraine, learning from each one. Same missiles threaten Japan, and Kyiv just shows its speaker what is inside them

Ukraine's Defense Intelligence, also known as HUR, has given Japan's parliament speaker a rare, close look at a North Korean weapon: the components of a ballistic missile Russia fired at Ukraine. Ukrainian officers have shown the parts to Eisuke Mori, speaker of Japan's House of Representatives, during his delegation's visit to Kyiv, HUR says on social media.

Ukraine has become the place where North Korea's missiles are tested in combat and taken apart. Pyongyang has supplied Russia with roughly 150 KN-23 and KN-24 ballistic missiles since late 2023, along with thousands of troops, and Russia has fired scores of them at Ukrainian cities.

Each strike gives Pyongyang combat data that has sharpened its weapons. Showing Japan the components turns that access into a prospect of future deterrence: the same missiles threaten the Asia-Pacific.

Ukraine hands Japan the evidence

Examining missile parts allows analysts to read the missile's technical characteristics, design, and the state of North Korea's arms industry, HUR says. Ukraine has found that the North Korean missiles falling on its cities are built partly from foreign parts, with components traced to companies in Britain, Japan, Switzerland, China, and the US, Radio Free Asia reports, evidence of how Pyongyang skirts sanctions to build them.

The threat reaches the Pacific

HUR frames the demonstration as a shared-security case. North Korean weapons endanger not only Ukraine but Japan and the wider Asia-Pacific, it says, while the Moscow-Pyongyang partnership lets Russia keep waging its war and lets Pyongyang build up its arsenal and refine its weapons.

"Countering this cooperation requires coordinated action by international partners. Sharing intelligence helps better assess common threats and find ways to overcome them," HUR states.

Pyongyang learns from the strikes

North Korea has sent Russia millions of artillery shells, rocket systems, and thousands of troops, and is paid in cash and technology, with one analyst estimating Pyongyang may have earned about $20 billion from the war. In return, the missiles' accuracy has improved as Pyongyang studies how they perform under fire, turning the war into a live proving ground for weapons built to threaten its neighbors.
