North Korea condemned Japan’s 2026 defense white paper on August 11, labeling it a reinvasion-minded one for the legalization of the operation of war machine
designed to justify an aggressive military buildup.
Pyongyang has ratcheted up its rhetorical pressure on Tokyo following the release of Japan’s latest defense strategy document. In a commentary carried by the official Korean Central News Agency, a North Korean analyst asserted that Japan’s 2026 White Paper groundlessly described
North Korea as the country’s greatest strategic challenge. According to state media, the characterization is merely a pretext used to justify its reckless arms buildup.
Reuters reports that Pyongyang has issued public statements criticizing Tokyo’s defense policy at least seven times since July.
Kim Yo Jong Warns of New Military Options Over Tokyo’s Strike Capabilities
The friction intensified when Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, issued a sharp warning regarding regional security. She stated that Pyongyang would pursue unspecified additional military options
in direct response to Japan’s expanding defense capabilities.
Kim accused Tokyo of reviving the ambitions of a war criminal state
and accelerating its transformation into a military power. Kim highlighted that Japan’s acquisition of long-range strike capabilities effectively places North Korea and its neighbors within range.
North Korea maintains that it will not remain a passive onlooker to these developments. Kim asserted that Pyongyang would make Japan feel that its security has been exposed to greater danger
as a consequence of what she characterized as Tokyo’s greediness.
Tomahawk Missile Tests and Joint Drills Fuel Pyongyang’s Ire
The immediate catalyst for North Korea’s fierce pushback centers on specific hardware demonstrations by Japan’s Self-Defense Forces. State media pointed directly to Japan’s recent Tomahawk test from the Aegis destroyer Chokai in the Pacific Ocean.

Beyond the cruise missile test, Pyongyang pointed to additional military actions that it views as provocative. Kim cited test-firings of other missiles alongside Tokyo’s participation in a U.S.-led joint military drill held in the Philippines in May.
Analysts note that these events fit a broader strategic narrative pushed by North Korea. According to Yang Moo-jin, a professor at the University of North Korean Studies in Seoul, Pyongyang’s messaging attempts to frame Tokyo’s military modernization as part of a broader American strategy to strengthen its proxy military capabilities to counter North Korea.
Washington’s Role and the Trilateral Security Alignment
North Korean leadership did not direct its criticism solely at Tokyo, training part of its rhetorical fire on the United States. Kim accused Washington of actively enabling Japan’s military expansion by supplying Tomahawk missiles, modifying naval vessels for their operation, and supporting missile testing.

This rhetoric targets the deepening trilateral security cooperation between the United States, South Korea, and Japan. While Washington and its allies maintain that these joint military exercises and defensive enhancements serve regional deterrence and stability, Pyongyang consistently portrays the alignment as preparation for an invasion.
Regional Analysts Anticipate Possible Missile Tests
The aggressive rhetoric from Pyongyang is rarely isolated. Following warnings of additional military options, North Korea test-fired a short-range ballistic missile toward the sea between the two countries, an action regional observers interpret as a direct tactical signal to Tokyo.
Academic experts monitoring the situation suggest that the current verbal escalation is likely laying the groundwork for concrete actions. Lim Eul-chul, a professor at Kyungnam University’s Institute for Far Eastern Studies, indicates that the messaging could precede future military demonstrations, which may include new missile tests or displays of undersea strike capabilities.
Whether Pyongyang will follow through with specific strategic provocations remains to be seen, but the friction over Japan’s defense build-up ensures that security tensions across Northeast Asia will remain exceptionally high.
