Japan’s Defense Minister Visits Australia and India for Missile Testing Talks, August 19

Defense Minister Shinjiro Koizumi is conducting a four-day visit to Australia and India from August 17 to 21, advancing Japan’s defense partnerships in the Indo-Pacific. In Canberra on August 18, Koizumi and Australian Deputy Prime Minister Richard Marles agreed to allow Japan’s Self-Defense Forces to test long-range missiles, including hypersonic variants, on Australian ranges. The two nations also discussed Japan’s export of upgraded Mogami-class frigates to Australia, marking Japan’s first large-scale defense equipment export.

Japan and Australia agree on missile testing cooperation

Defense Minister Shinjiro Koizumi and Australian Deputy Prime Minister Richard Marles met in Canberra on August 18 and agreed to advance arrangements for the SDF to conduct test launches of long-range missiles in Australia. Japan has limited domestic testing facilities for stand-off missiles, which strike targets from outside an adversary’s attack range. The two countries will move forward with plans to use Australian facilities for hypersonic missiles. Koizumi told reporters the development would be “groundbreaking” if realized and pledged to “accelerate discussions.”

Mogami-class frigate export advances Japan’s defense industry

Koizumi and Marles also reviewed progress on exporting an upgraded version of Japan’s Maritime SDF Mogami-class frigate to Australia. The class features reduced crew requirements and advanced stealth capabilities. This would represent Japan’s first overseas transfer of large-scale defense equipment. New Zealand has also shortlisted the upgraded Mogami-class frigate as a candidate for its next-generation fleet, with a final selection expected as early as 2027. Japan expects that if New Zealand adopts the same model, SDF units will benefit from improved interoperability and expanded logistics networks in the Indo-Pacific.

India visit focuses on maritime security and drone cooperation

Koizumi is scheduled to meet with Indian Defense Minister Rajnath Singh in New Delhi on August 20. The two nations plan to discuss maritime security cooperation, defense equipment and technology sharing, and joint development of unmanned aircraft. India and Japan have strengthened defense ties in recent years as both seek to counter regional security challenges in the Indo-Pacific.

Tight schedule draws criticism over substance and messaging

Koizumi posted on X that the trip involves three nights on aircraft and one night in a hotel, calling it a “bullet trip.” Critics questioned the phrase, suggesting it amounts to “busy-ness signaling” to voters. A veteran political journalist noted that while cabinet-level visits carry strategic value, the compressed schedule raises questions about whether substantive outcomes can be achieved. Japan’s annual budget for Diet member overseas visits is approximately 500 million yen, funded by taxpayers.

Final Thoughts

Japan is rapidly expanding its military partnerships and defense exports across the Indo-Pacific. The missile testing agreement with Australia and potential frigate sales to New Zealand signal Tokyo’s strategy to strengthen regional deterrence networks while boosting its defense industry.
