North Korea Criticism of Japan Explained: What Is Driving the Escalation?

North Korea Criticism of Japan Explained: North Korea has stepped up its criticism of Japan, accusing it of boosting its military capabilities and strengthening security cooperation with the US and South Korea. The campaign has grown significantly since early July, with more than a dozen critical statements and commentaries emerging in North Korean state media.

The stronger attitude comes as Japan continues to overhaul its defense policy and North Korea strengthens military relations with Russia. Analysts say North Korea’s new criticism of Japan is not simply about Tokyo, but also part of a larger campaign by Pyongyang to portray Northeast Asia as a region divided into two opposing military blocs.

North Korea Criticism of Japan Targets Expanding Defence Capabilities

North Korea has focused on many important shifts in Japan’s defense policy. Tokyo intends to improve counter-strike capabilities, test a US-made Tomahawk cruise missile, raise defense budget, and release Japan’s annual defense white paper.

Kim Yo Jong, the sister of North Korean leader Kim Jong Un, has warned that Pyongyang may examine “additional military options” in reaction to Japan’s growing military capability. North Korea later slammed Japan’s 2026 defense white paper, claiming it was a blueprint designed to legitimize military expansion.

Japan declared in 2022 that it will increase defense spending to 2% of GDP, citing increased security concerns with China, Russia, and North Korea. The country is also investing in long-range weaponry, such as Tomahawk missiles, which can strike targets more than 1,000 kilometers away.

Japan’s government is also slated to review its national security plan this year, potentially leading to increased expenditure on drones, weapons manufacture, and other defense capabilities.

North Korea has also criticized the yearly military exercises between the United States and South Korea, known as Ulchi Freedom Shield. Pyongyang claims that increased collaboration between the US, Japan, and South Korea is forming a “nuclear alliance,” while Washington and Seoul insist that the exercises are simply defensive.

North Korea Criticism of Japan Reflects Broader Regional Strategy

According to analysts, North Korea’s current criticism of Japan is closely related to Pyongyang’s changing foreign ties. According to Park Won-gon, a professor at Seoul’s Ewha Womans University, North Korea is aiming to portray Northeast Asia as a competition between the United States, South Korea, and Japan on one side and North Korea, China, and Russia on the other.

This narrative might help Pyongyang deepen connections with Beijing and Moscow while also bolstering its claim that nuclear weapons are necessary for national security. South Korea’s Unification Ministry has reached a similar conclusion, stating that North Korea now sees Japan’s defense changes, South Korea’s military preparations, and trilateral cooperation as major security concerns.

North Korea Criticism of Japan Comes as Missile Activity Continues

North Korea’s recent missile launches have received little attention, which is another rare trend. Despite the fact that Iran launched ballistic missiles last week and again this week, state media did not immediately publish the launches, which is unusual.

Analysts speculate that the tests may have included improved versions of current short-range missiles. Some believe Russian technical support is helping DPRK develop the weapons, while others feel Pyongyang is avoiding publicity if they are being prepped for export to Russia.

North Korea’s growing military ties with Russia have become an increasingly essential factor in understanding its weapons development. Analysts believe that battlefield experience and Russian aid may have helped upgrade some North Korean missile systems.

What the North Korea Criticism of Japan Means for Northeast Asia

The overall area impact could be severe. Japan’s defense buildup, increased collaboration between the United States, Japan, and South Korea, and North Korea’s tighter connections with Russia and China all have the potential to exacerbate the Northeast Asian security divide.

Pyongyang’s portrayal of its adversaries as a cohesive military bloc helps justify its weapons programs and strengthens political and strategic backing from Moscow and Beijing. As regional military cooperation grows, North Korea’s criticism of Japan is likely to remain a crucial component of the larger geopolitical rivalry in Northeast Asia.
