Japan Edges Towards Hosting Nuclear Weapons

Rajeswari Pillai Rajagopalan

It looks like Japan will finally cast aside its ban on hosting nuclear weapons—specifically, those of the United States.

Moving towards action she called for last year, Prime Minister Sanae Takaichi is reviewing the three principles that have kept Japan at arm’s length from nuclear weapons since 1967. The ban is the third of those principles, the other two holding that Japan must neither own nor produce nuclear weapons.

Japan is responding to what it perceives as worsening security dynamics in the region, surrounded as it is by three nuclear powers—China, Russia and North Korea—all of which are engaging in aggressive behaviour.

A 14 November Kyodo news report citing government sources noted that any changes in the three principles would constitute a major shift in Japan’s security policy in line with the ‘tough security environment.’ According to the report, the Japanese government sees the ban on placement of nuclear weapons within its territory as ‘weakening the effectiveness of the nuclear deterrence provided by its ally, the United States.’ This is particularly relevant as U.S. considers developing a nuclear-armed sea-launched cruise missile, known as SLCM-N, to strengthened deterrence against China.
