CaliToday (21/12/2025): As the security landscape of East Asia undergoes its most significant transformation since the Cold War, a new war of words has erupted. North Korea, through its state-run news agency KCNA, has issued a scathing call to “thoroughly restrain Japan’s nuclear ambitions,” accusing Tokyo of using regional instability as a pretext to abandon its decades-long pacifist tradition.
1. The KCNA Broadside: A Warning of "Double Standards"
Pyongyang’s latest rhetoric centers on what it describes as Tokyo’s "clandestine intent" to acquire nuclear capabilities. A spokesperson for North Korea’s foreign policy department claimed that Japan is actively seeking a path toward nuclearization by questioning the Three Non-Nuclear Principles the bedrock of Japan’s post-war identity.
Crucially, North Korea linked this shift directly to Washington’s recent decision to allow South Korea to develop nuclear-powered submarines (SSNs). Pyongyang argues that by greenlighting Seoul’s undersea nuclear ambitions, the U.S. has opened a "Pandora’s box," emboldening Japanese hawks to seek similar exceptions.
2. The Takaichi Factor: Challenging the 1967 Taboo
At the heart of the controversy is Prime Minister Takaichi Sanae. Known for her staunchly conservative views, Takaichi has reportedly entered internal discussions regarding a re-evaluation of the Three Non-Nuclear Principles:
The Principles: Established in 1967, they state that Japan shall not possess, not produce, and not permit the introduction of nuclear weapons.
The Contradiction: Sources close to the Prime Minister’s Office suggest that some officials believe Japan requires its own nuclear deterrent or at least a "nuclear sharing" arrangement to counter the growing threats from China and North Korea.
While the Prime Minister’s Office officially denied that a formal policy change has been discussed with Takaichi, the mere mention of reconsidering these principles has sent shockwaves through Japanese society.
3. A Nation Divided: Pacifism vs. Realpolitik
The prospect of a nuclear-armed Japan remains one of the most polarizing issues in the country. The debate faces two massive hurdles:
The Peace Constitution: Article 9 of Japan’s Constitution renounces war and the maintenance of "war potential." While interpreted to allow for self-defense, many legal scholars argue nuclear weapons would be a bridge too far.
The "Hiroshima Legacy": As the only nation to have suffered a nuclear attack, Japan has a deep-seated public allergy to nuclear weaponry. Any move toward nuclearization risks massive domestic protests and a collapse in public trust.
4. Regional Repercussions
The "Nuclear Domino" theory is no longer a theoretical exercise. Analysts suggest that if the U.S. continues to expand nuclear cooperation with its allies (like the AUKUS deal with Australia or the SSN deal with South Korea), it becomes increasingly difficult to deny Japan the same strategic depth.
“If Tokyo even hints at a nuclear path, it provides Pyongyang with the ultimate justification for its own arsenal,” says a regional security expert. “It creates a feedback loop where every 'defensive' move by one party is viewed as an existential 'offensive' threat by another.”
