Kim Yo Jong, sister of North Korean leader Kim Jong Un, said Wednesday that North Korea could adopt "additional military options" against Japan [1, 2].
The warning follows Japan's first live-fire launch of a U.S.-made Tomahawk long-range cruise missile, a move that signals a significant shift in Tokyo's military capabilities [1, 3].
On July 29, 2026, Japan's Maritime Self-Defense Force fired the missile from the JS Chokai [1, 3]. The ship is a Kongo-class Aegis destroyer commissioned in 1998 and modified in 2025 [3]. Japan said the test was part of U.S.-led drills intended to enhance its strike capability [4, 5].
Kim Yo Jong issued her response through the state media agency KCNA on Aug. 5, 2026 [1, 2]. She said Japan is abandoning its traditional defensive posture in favor of a more aggressive strategy.
"Japan is turning its armed forces into a force capable of pre-emptive attacks and overseas military operations," Kim Yo Jong said [2].
North Korean officials view the acquisition and testing of long-range cruise missiles as a transition toward a pre-emptive, overseas-capable force [4, 5]. The Tomahawk missile provides a capability for precision strikes over long distances, which Pyongyang interprets as a direct threat to its security.
"We will adopt 'additional military options' against Japan," Kim Yo Jong said [1].
“"We will adopt 'additional military options' against Japan,"”
The deployment of Tomahawk missiles represents a pivot in Japan's defense strategy toward 'counterstrike' capabilities. By moving beyond a purely defensive shield, Japan is aligning its military posture more closely with U.S. offensive capabilities, which increases regional deterrence but also heightens tensions with North Korea and China.
