North Korea warns it will take unspecified “additional military options” in response to Japan’s expanding defense posture. In statements carried by North Korea’s state media, Kim Yo Jong, sister of North Korean leader Kim Jong Un, says Pyongyang will not remain a “passive onlooker” as she characterizes Japan’s transformation into a military power. Sources cite Japan’s recent test-firing of US-made Tomahawk long-range cruise missiles as one example, and also point to Japan’s participation in US-led military exercises in the Philippines. North Korea frames these steps as evidence that Tokyo is accelerating moves toward capabilities it describes as enabling preemptive attack, and accuses Japan of reviving ambitions of a “war criminal state.” Multiple outlets also report that Kim Yo Jong links Japan’s actions to broader US-North Korea dynamics, including criticism of Washington’s role in allowing or enabling Japan’s rearmament. Japan’s current defense expansion is therefore presented by North Korea as a justification for further steps, though the exact nature of the “additional military options” is not specified in the reports.
