Japan’s Defense Minister Pushes for Nuclear Weapons Debate

Japanese Defense Minister Shinjiro Koizumi has reignited the debate over nuclear weapons, calling for an open discussion on acquiring them and nuclear-powered submarines. In an interview last Monday, Koizumi argued that Japan, the sole nation attacked with atomic bombs, should explore these options without restrictions, citing threats from China, Russia, and North Korea. He pointed to other countries like France and Finland, which are expanding their nuclear capabilities, as examples of a global shift toward such measures.

Koizumi's remarks come amid a broader push for remilitarization by Japan's far-right coalition government led by Prime Minister Sanae Takaichi. The government is preparing to revise Japan's 'three non-nuclear principles,' which prohibit possessing, producing, or allowing nuclear weapons on its territory. Historically, Japan has violated these principles, such as allowing US warships carrying nuclear weapons to dock at its ports and permitting nuclear weapons in Okinawa under emergency conditions.

China has criticized Koizumi's comments, with Foreign Ministry Spokesman Guo Jiakun calling them a 'serious provocation' and a violation of the Non-Proliferation of Nuclear Weapons Treaty. Meanwhile, Japan's Defense Ministry has requested a record-high budget of 8.9 trillion yen ($56.4 billion) for fiscal 2027, with expectations that military spending will exceed 10 trillion yen in the initial budget proposal. The government is also investing heavily in missiles, drones, and other advanced weaponry.

The push for nuclear capabilities and increased military spending reflects Japan's preparation for potential involvement in a broader conflict, particularly with China. Koizumi's remarks have escalated tensions, as Tokyo faces pressure from allies like the US to spend more on defense. The Trump administration is urging Japan to allocate 3.5 percent of its GDP to military spending, a target South Korea aims to reach by 2035.
