Japan’s defence minister pushes for stronger military and constitutional reform

Defence Minister Shinjiro Koizumi said on the BBC that Japan must lift its defence capabilities and consider a revision to its long‑standing pacifist constitution, arguing the current security environment demands it.

He highlighted the need to strengthen the US‑Japan security alliance, deepen partnerships with other friendly states in the Indo‑Pacific, and invest in new surface‑to‑ship missiles and unmanned drones. Japan’s defence budget is now planned to reach 2 % of GDP, double the long‑post‑war benchmark.

Koizumi announced a milestone policy change that allows Japan to sell or transfer lethal weapons to 17 members of the Stability‑Reinforcement Agreement, including the United States and the United Kingdom. He outlined ongoing talks for Japanese warships with Australia, talks on used destroyers with the Philippines, and consultations with Indonesia and New Zealand.

He warned that China’s growing naval presence and North Korea’s missile tests make Japan’s current defensive posture inadequate. The ministry’s latest white paper declares China’s military moves as the “greatest strategic challenge.”

Koizumi said the government could formalise the status of the Self‑Defence Forces, arguing it is vital for Japan to maintain pride and honour in its military. Critics, however, contend that officially recognising the SDF could undermine Article 9’s pacifist clause.

The Defence Minister stressed that any constitutional revision would be decided via a national referendum, noting the process would involve major political judgments about timing and circumstances.

He remains hopeful that Japan can play a key role in maintaining regional security beyond its relationship with the United States, highlighting the need for an independent and uniquely Japanese contribution to peace in the Indo‑Pacific.
