China Claims Japan Could Go Nuclear 'Virtually Overnight' in New Security Report

A nuclear-armed Japan could emerge "virtually overnight," according to a startling new security report from Beijing. Released on January 8, 2026, the document suggests the nation's technological prowess and material stockpiles bring it to the very threshold of nuclear armament.

Key Findings in the China Report on Japan Nuclear Capability

The official report states that Japan "may already have produced weapons-grade plutonium in secret." It further argues that Tokyo possesses the economic and technological foundations to achieve full nuclear status in an incredibly short period. China has long pointed to Japan's civilian nuclear program and its 45-ton stockpile of plutonium as a latent security threat to the region.

The Biden-Xi Connection: Citing US Intelligence

Intriguingly, the report leverages past comments from former US President Joe Biden. During talks with President Xi Jinping, Biden reportedly noted that Japan has the capacity to go nuclear almost instantaneously. By citing Biden, China aims to demonstrate that even Japan's closest ally recognizes its breakout potential.

Geopolitical Stakes of a Nuclear Japan

While Japan maintains its "Three Non-Nuclear Principles," the regional power balance is shifting. Beijing's report likely serves as a diplomatic deterrent against increasing military cooperation between the US and Japan. It's clear that any movement toward armament would trigger a massive security crisis in East Asia, potentially leading to a regional nuclear domino effect.
