In a historic departure from its postwar pacifist constitution, Japan has dismantled one of its final barriers to participating in the global arms trade, approving the export of lethal weapons for the first time since 1945. The cabinet of Prime Minister Sanae Takaichi endorsed new guidelines that will allow the sale of fighter jets, missiles, and destroyers abroad, a move designed to bolster both national defence and a domestic industry seen as a new engine for economic growth. This strategic pivot, long in the making, effectively marks the end of Japan's self-imposed restrictions on lethal arms sales, a cornerstone of its identity since the Second World War.

The policy shift arrives as Prime Minister Takaichi marks six months in office, a period defined by electoral success but also by growing unease within her own Liberal Democratic Party. Analysts in Tokyo note that her assertive style and controversial domestic policies, such as a planned suspension of consumption tax, have caused friction with the party's old guard, who reportedly feel she is acting 'like a queen'. Despite this internal resistance, Takaichi's government is pressing ahead with a security agenda driven by perceived threats from an increasingly assertive China and a volatile North Korea.

Viewed from Washington and Canberra, the change is largely welcomed as a step towards deeper defence integration with a key ally in the Indo-Pacific. However, from Beijing, it is met with sharp criticism, a sentiment intensified by Takaichi's recent ritual offering to the Yasukuni Shrine, which neighbours see as a symbol of Japan's imperial past. This diplomatic friction underscores the regional tensions driving Tokyo's military recalibration, as it seeks to strengthen partnerships with Southeast Asian nations and beyond.

This Japanese pivot occurs against a backdrop of global rearmament and strategic reassessment. In Europe, Ukraine's President Zelensky has announced ambitions to develop a home-grown anti-ballistic missile system within a year, seeking to reduce dependence on waning supplies of American Patriot missiles. Meanwhile, progressive leaders like Italy's Elly Schlein are advocating for a swift transition to renewable energy, arguing that continued purchases of Russian gas only fund Putin's war machine—a view echoed by Spain's Pedro Sanchez and reflecting a broader European push for energy independence and defence autonomy.

The long-term implications of Japan's new export regime are profound. It signals a definitive end to the Yoshida Doctrine's constraints, potentially transforming Japan into a significant player in the international defence market. For the Takaichi administration, the challenge will be to navigate domestic political resistance while managing the geopolitical repercussions of a more militarily capable Japan, all within an increasingly volatile security landscape where allies are bolstering their own capacities and adversaries are watching closely.
