The Role of Russia in Japan's Arctic Policy

The Arctic Institute  By Pavel Devyatkin  March 31, 2026

In the Arctic, Japan’s energy security imperatives collide with its anxieties about Russia and China. As a non-Arctic state dependent on imported energy and global shipping lanes, Japan views Russia as both an indispensable partner and a potential adversary.

This tension has sharpened considerably as Moscow has drawn closer to Beijing, prompting Tokyo to adopt a more security-oriented posture that could unsettle the Arctic’s traditionally cooperative governance arrangements.

Japan’s relationship with Russia carries considerable historical weight. The Russo-Japanese War of 1904-1905, though a Japanese victory, offered both nations lasting lessons about maritime power and Arctic navigation. The Russian Empire’s defeat stemmed partly from its lack of icebreaking capability and the grueling voyage its Baltic Fleet was forced to make around Africa. The experience shaped subsequent Soviet and Russian investment in what has become the world’s most powerful icebreaker fleet.

The post-Cold War period promised new opportunities for cooperation. Japanese companies took stakes in Russian energy projects and began exploring the commercial potential of the Northern Sea Route (NSR). Today, however, such cooperation sits uneasily alongside intensifying great power rivalry.

Russia as gatekeeper to Japan’s Arctic ambitions

Russia’s control over the NSR places it at the center of Japan’s Arctic calculations. For Japan, which became an Arctic Council observer in 2013, access to this route could reduce shipping distances to Europe by as much as 40%, while Russian Arctic energy resources offer a valuable alternative to Middle Eastern suppliers.

Japanese companies hold positions in major Russian energy projects including Sakhalin-1, Sakhalin-2, and Arctic LNG 2. Despite considerable Western pressure following 2022, Japan has opted to protect these investments. Prime Minister Kishida stated after the 2022 G7 summit: “We will take steps to phase out Russian oil imports in a manner that minimizes adverse effects on people’s lives and business activities. But we plan to keep our interests in the two Sakhalin LNG projects unchanged.”

The China factor and Japanese militarism

Japan’s Arctic anxieties cannot be understood apart from the deepening Russia-China relationship. Joint infrastructure development, Chinese capital flowing into Russian Arctic energy projects, coordinated shipping initiatives, and military collaboration have fueled concern in Tokyo that a Sino-Russian sphere of influence may be taking shape in the region.

When Foreign Minister Yoko Kamikawa visited Sweden in 2024, she presented Japan’s Northern European Diplomacy Initiative, a framework centered on defense cooperation with Arctic states including Sweden, Norway, Denmark, and Finland. The initiative marked a notable shift from economic engagement toward security alignment and a reorientation with significant implications for Japan’s Arctic posture.

Perhaps more consequentially, Prime Minister Sanae Takaichi has signaled a willingness to abandon Japan’s Three Non-Nuclear Principles, the pledge since 1967 not to produce, possess, or permit nuclear weapons on Japanese soil. These principles are tied to Japan’s identity as the only nation to suffer atomic bombings in war.

In a book published before becoming Prime Minister, Takaichi called the no-nukes commitment an obstacle “if we expect the United States to provide extended deterrence.” In a November 2025 parliamentary session, she declined to guarantee that Japan’s forthcoming National Security Strategy would retain all three principles.

These developments have drawn sharp reactions from Beijing. Bilateral tensions escalated after Takaichi declared that same month that a Chinese attack on Taiwan would constitute “a situation threatening Japan’s survival,” potentially warranting a military response.

China’s Ministry of Defense cautioned that intervention would end in a “crushing defeat” for Japan. Chinese arms control analysts have framed Tokyo’s nuclear reconsiderations as destabilizing moves that jeopardize regional order. Russian and Chinese officials have taken a common stance against Japanese militarism.

Navigating tensions

Japan’s Arctic policy contains an inherent tension. Tokyo cannot credibly adopt a confrontational stance toward Moscow (or Beijing) while remaining deeply invested in Russian resource projects. That Japan has continued using the NSR despite its public criticism of Russia suggests that commercial considerations still carry substantial weight.

Japan’s 2015 Arctic Policy outlines three key interests: research and development, international cooperation, and sustainable use. These principles provide a foundation that could temper the security-driven turn now underway.

In general, Russia’s place in Japan’s Arctic calculus reflects a deeper struggle between economic pragmatism and strategic anxiety. As gatekeeper to the NSR and a critical energy supplier, Russia remains central to Japan’s Arctic plans.

Yet anxiety over Sino-Russian alignment has nudged Tokyo toward a harder posture, including nuclear deliberations, that could compromise both its energy interests and Japan’s role in the multilateral frameworks that have long governed the Arctic.

A sustainable approach will require Japan to balance security concerns with continued diplomatic engagement. Energy ties with Russia, however strained, offer channels for communication that pure confrontation would foreclose. The Arctic’s unique history of cooperation, even between adversaries, offers a model for managing competition without military escalation.

How Japan navigates these crosscurrents will matter for the broader Arctic. Prioritizing diplomacy over confrontation would help preserve the collaborative ethos that has largely distinguished Arctic governance. The alternative, a militarized Arctic shaped by great power competition, serves no one’s interests, least of all Japan’s.
