Japan used a UNGA-week Ocean Panel leaders’ meeting in New York to highlight ocean-climate cooperation as Tokyo works to deepen maritime partnerships beyond hard-security messaging.1
Its priorities included blue-carbon measurement, fisheries-resource management, marine ecosystem conservation and support for small island developing states.
The Foreign Ministry said Ambassador Sugiura Masatoshi, director-general for global issues, attended the September 23 meeting on behalf of Prime Minister Takaichi. Japan linked its remarks to the Island States Ocean Summit held in Tokyo in June, where leaders discussed conservation, sustainable ocean use and sea-level rise.1
Why it matters
The intervention shows Tokyo pairing its Free and Open Indo-Pacific agenda with cooperation on climate resilience and ocean governance.
For island states facing sea-level rise, fisheries pressure and marine ecosystem degradation, those issues are core security concerns. They are also less confrontational than military or strategic-competition framing.
Japan’s Ocean Panel message focused on implementation ahead of COP31. That included work to quantify greenhouse gases absorbed and stored by blue-carbon ecosystems, as well as support for fisheries and marine conservation in countries such as small island developing states.1
The UNGA-week pattern
Tokyo reinforced the theme at a separate high-level meeting on sea-level rise on September 24. The Foreign Ministry said Sugiura again referred to the June Island States Ocean Summit and emphasized Japan’s financial and technical assistance for climate-vulnerable countries, including support for resilience, energy transition and decarbonization.3
The broader UNGA schedule also placed ocean and island diplomacy alongside Japan’s conventional diplomatic activity. MOFA’s UNGA hub listed Japan-Maldives and Japan-Fiji foreign ministers’ meetings, as well as a ministerial meeting on maritime cooperation to achieve a secure and stable maritime domain.5
Pacific partnerships, softer channel
Regional reporting from PACNEWS said Japan and Fiji used their September 23 UNGA-side talks to reaffirm cooperation on disaster-risk reduction and Pacific resilience.
The report also said Foreign Minister Motegi framed Japan’s updated Free and Open Indo-Pacific concept around support for Fiji and other regional countries’ resilience and their “freedom to decide for themselves.”6
That combination is politically useful for Tokyo. Japan can continue to signal rule-of-law and maritime-order priorities while engaging island partners through climate adaptation, fisheries, disaster readiness and ocean science — issues Pacific governments have long treated as immediate national priorities.
