Japan Lifts Post-WWII Arms Export Bans Amid US Uncertainty

Japan is preparing to ease long-standing restrictions on arms exports, marking its biggest defence policy shift since World War II. The move comes amid uncertainty over security commitments from the United States under Donald Trump and growing strain on US weapons supplies due to ongoing conflicts in Ukraine and tensions involving Iran.

Prime Minister Sanae Takaichi is leading efforts to strengthen Japan’s defence industry, with countries like Poland and the Philippines showing interest in potential deals involving naval vessels and defence systems. Japanese defence firms are expanding hiring and production capacity as European and Asian partners explore joint development projects.

The policy shift is driven by concerns over the reliability of US security guarantees, supply shortages caused by global conflicts, rising regional threats particularly from China, and Japan’s desire to strengthen its domestic defence industry. Analysts note that Japan’s move reflects a broader transition in global security dynamics where reliance on a single dominant supplier, particularly the United States, is becoming increasingly risky for allies.

By stepping into the arms export market, Japan aims to address immediate supply gaps while positioning itself as a long-term strategic partner in defence cooperation. This could lead to diversification of global arms supply chains away from the United States, stronger defence cooperation among US allies, and increased geopolitical competition in Asia, and Europe.

Despite largely isolating itself from global arms markets since World War Two, Japan spends enough on its own military – $60 billion this year – to sustain a sizeable defence industry capable of manufacturing advanced systems like submarines and fighter jets.

Our country faces the harshest and most complicated international security environment since the end of World War II. It is necessary to further promote defence equipment exports.

Shinjiro Koizumi, Japanese Defence Minister

The new Japanese government has moved swiftly to signal its intent to relax weapons export rules amid worsening global insecurity and rising defence spending. Based on the agreement between the Liberal Democratic Party and the Japan Innovation Party, necessary discussions with related ministries and agencies will proceed to formalise the changes.

Japan’s announcement comes at a time when the country is looking to rapidly expand its defence exports.

Interest from international buyers includes the Polish military and the Philippine navy, both undergoing modernisation amid regional security challenges. Japanese officials and foreign diplomats in Tokyo have confirmed strong interest from Warsaw to Manila as the country prepares to formally adopt the new rules as soon as this month.
