Every time a Russian official steps foot on Etorofu or Kunashir, the diplomatic playbook in Tokyo opens to the exact same page. The Foreign Ministry summons the Russian ambassador, stern protests are lodged, ink is spilled, and talking heads on morning news programs nod solemnly about territorial integrity and international norms.
It is ritualistic theater. And it is completely useless.
For decades, the mainstream consensus in Japanese foreign policy circles has been that persistence pays off—that if Tokyo just keeps repeating the phrase "Northern Territories" with enough moral conviction, Moscow will eventually hand back a strategic archipelago it annexed in the final days of the Second World War. This is diplomatic fantasy masquerading as strategy. I have spent years watching governments cling to outdated maps while geopolitical reality leaves them behind. The harder Tokyo pushes its legacy claims, the more entrenched Moscow becomes, and the more irrelevant Japan looks on the global stage.
Stop waiting for a nostalgic return to 1945. The Kuril Islands dispute is not a legal puzzle waiting for a clever arbiter; it is a monument to realpolitik, and Tokyo is losing because it refuses to play the actual game.
The Geography of Dead Ends
To understand why the official stance is broken, you have to look past the emotional rhetoric and examine the strategic reality. The islands known in Japan as the Northern Territories and in Russia as the Southern Kurils—Itorofu, Kunashir, Shikotan, and the Habomai islets—sit right at the throat of the Sea of Okhotsk.
For Moscow, this is not about historical sentimentality or real estate development. It is an uncompromisable bastion for nuclear ballistic missile submarines. The Sea of Okhotsk is a heavily fortified redoubt where Russia hides its strategic deterrent from American and allied surveillance. Handing any of these islands back to a close United States security partner is a non-starter for any Kremlin administration, regardless of who sits in the president's chair.
When mainstream analysts suggest that a breakthrough is just around the corner if Tokyo offers enough economic cooperation or joint development projects, they are misreading the fundamental calculus. I have seen corporations and governments sink billions into joint economic zones that ultimately collapsed because neither side could agree on sovereignty. Moscow wants Japanese cash and technology, but it has zero intention of trading sovereign territory for a few fish processing plants or wind turbines.
To believe otherwise is to ignore how great powers operate. Sovereignty trumps commerce every single time.
Dismantling the Legalistic Delusion
The foundational argument of Japan's diplomatic strategy rests on the San Francisco Peace Treaty of 1951 and bilateral declarations that Tokyo interprets as retaining sovereignty over the southern chain. Lawyers love this debate. Governments fund think tanks to parse the historical definitions of island groups.
International law in the absence of enforcement mechanisms is merely a suggestion. Russia controls the ground, stations military hardware there, issues passports, and builds radar installations. When Tokyo summons an ambassador, it is performing a bureaucratic reflex that satisfies domestic political constituencies while altering nothing on the map.
Imagine a corporate executive who continues to dump capital into a failing product line simply because the original business plan promised profitability twenty years ago. They would be fired before lunch. Yet in statecraft, repeating a failed approach for three-quarters of a century is somehow praised as steadfastness.
The legalistic approach fails because it assumes Russia cares about international jurisprudence regarding post-war settlements. Moscow views the outcome of World War II through the lens of blood and conquest, not legal technicalities. Until Tokyo accepts that possession is not nine-tenths of the law—it is ten-tenths when backed by strategic necessity—the diplomatic dance will remain a hollow ritual.
The Opportunity Cost of Obsession
The real tragedy of the Northern Territories fixation is not just that it fails to yield results. It is the massive opportunity cost it imposes on Japanese foreign and economic policy.
By tying normalization with Moscow to the return of the islands, Tokyo has consistently handcuffed its broader Eurasian strategy. While China expands its footprint across Central Asia and deepens its economic partnership with Russia, Japan remains sidelined, chained to a diplomatic anchor that prevents it from exercising flexible diplomacy in its own backyard.
Energy security provides a prime example. For years, Japanese utility companies navigated complex Russian energy projects with bated breath, constantly worried that political friction over the islands would upend LNG supplies from Sakhalin. Instead of diversifying supply chains cleanly or building robust regional architectures that bypass the sovereignty trap, Tokyo kept one foot in the door of a dead-end bilateral dispute.
The obsession with the islands creates a domestic political trap. Generations of politicians have promised voters that the territories will return. Admitting defeat now feels like political suicide. So the charade continues, with each administration kicking the can down the road, hoping future leaders will somehow inherit a miraculously compliant Moscow.
Miracles do not happen in geopolitics. Leverage does. And right now, Tokyo has none over this issue.
A Cold-Eyed Alternative
If the current trajectory is a dead end, what does a winning strategy look like? It starts with abandoning the illusion of territorial recovery and pivoting toward risk management and regional containment.
First, decouple economic pragmatism from territorial nostalgia. If trade or resource access serves Japan's immediate national interest, pursue it through transactional, eyes-wide-open frameworks that do not require recognizing Russian sovereignty while acknowledging the factual reality of their administration. Drop the pretense that economic cooperation is a stepping stone to a land swap.
Second, integrate the security threat directly into broader northern defense planning. Instead of protesting visits by Russian officials, focus on hardening maritime surveillance, upgrading anti-submarine capabilities in the Hokkaido region, and working seamlessly with regional allies to monitor movements through the Kuril straits. Treat the islands not as stolen property waiting to be reclaimed, but as an adversarial military outpost that must be contained.
Third, manage domestic expectations with brutal candor. Leaders must possess the political courage to tell the public that the map of 1945 is gone forever. Clinging to a phantom past prevents the nation from forging a proactive, forward-looking security posture in an era defined by great power competition.
The world has moved on. The submarines do not care about historical treaties, and the Kremlin does not care about diplomatic demarches. It is time for Tokyo to stop summoning ambassadors and start facing reality.
