Japan's first-ever Tomahawk test launch: On July 29, 2026 (Japan time), the Japan Maritime Self-Defense Force (JMSDF) fired a U.S.-made Tomahawk cruise missile from the Aegis destroyer JS Chokai in the Pacific Ocean, marking a major milestone in Tokyo's push for long-range strike capability .
Accelerating military buildup beyond defensive posture: Kim argued that Japan was moving away from its constitutionally limited "exclusively defense-oriented" policy .
U.S. enabling of Japanese rearmament: She denounced the United States for allowing Tokyo to pursue this rearmament .
While not all details appear in every single news report covering her statement, the broader backdrop reported around the same time includes:
Japan's missile acquisition plans: Japan had agreed to purchase 400 Tomahawk cruise missiles and allocated over $2 billion for them as part of its historic defense expansion .
Japan's record defense budgets: Japan's Cabinet approved a record defense budget exceeding ¥9 trillion (approximately $58–$59 billion) for fiscal 2026, and an 8.7 trillion yen (~$55 billion) budget for fiscal 2025, as part of a plan to nearly double annual spending to 2% of GDP by 2027 .
Defense Minister's urgency call: Defense Minister Shinjiro Koizumi stated in the 2026 defense white paper that Japan needed to boost its military with a "sense of urgency and crisis" .
2026 Defense White Paper: Released on August 4, 2026 — one day before Kim's statement — it described the security environment around Japan as "the most severe and complex since the end of World War II", citing threats from China, Russia, and North Korea, including growing military coordination among them, provocative bomber patrols, and Moscow's support for North Korea's military modernization .
Japan's self-defense justification: Japan's Ministry of Defense has consistently defended the policy as strictly for self-defense, arguing the long-range strike capability is needed to deter regional threats .
China's concerns: China criticized the Tomahawk test launch, claiming it "reflects Japan's intention to undermine China's interests and harm the Chinese people" and expressed concerns over a resurgence of Japanese militarism .
Several outlets noted that Kim Yo Jong's warnings serve a dual purpose. The Korea Times and others observed that Pyongyang's fiery rhetoric against Japan's military expansion helps justify North Korea's own weapons development programs, including its nuclear and missile tests, by framing them as defensive countermeasures against an increasingly militarized Japan backed by the U.S. . This pattern is standard for the regime: when external threats are amplified, internal repression and weapons development are portrayed as necessary for national survival.
