As the global geopolitical architecture is shaken by systemic shocks—such as great power competition, the war in Ukraine, and disruptions in energy supply chains—it is forcing states to recalibrate their “high politics” priorities. In this environment of uncertainty, Japan—a key actor in the Asia-Pacific—faces a profound strategic dilemma between its normative commitments to the Western alliance and the geo-economic realities imposed by its chronic energy dependence. The need to integrate into the U.S.-led values-based order while managing regional threats has pushed Tokyo into a search for a pragmatic balance. The most evident and paradoxical manifestation of this conflict between national survival and alliance obligations is embodied in Japan’s current foreign policy reflexes, which it has been compelled to shape along the Moscow axis.
Although Russia’s 2022 intervention in Ukraine has pushed Japan to increase its defense spending and align with Western sanctions, Tokyo’s current approach is one of “calibrated strategic ambiguity” and a realpolitik balancing strategy. On the one hand, Japan is defending the normative order and transforming its pacifist framework out of concern that “today’s Ukraine could be tomorrow’s Japan”; on the other hand, it is maintaining its energy dependence through the Sakhalin-2 project and preserving its goal of resolving the Kuril Islands issue and concluding a peace treaty. This asymmetrical structure—which incorporates both energy pragmatism at the state level and backchannel dialogues facilitated by figures like Muneo Suzuki—has transformed Tokyo’s policy into a “controlled tension” mechanism managed between the Western alliance and national survival.[i]
At the core of this controlled tension lies a shrinking diplomatic maneuvering space. It is argued that Japanese Prime Minister Sanae Takaichi must adopt the “strategic realism” of the Shinzo Abe era rather than ideological rigidity in the face of the country’s chronic internal and demographic challenges. While easing ties with Russia—despite Western pressure—is viewed as a geopolitical necessity in light of energy and North Korea-related security concerns; it is emphasized that balancing the Taiwan crisis with China in pursuit of regional stability represents the most rational option for fortifying Japan’s strategic autonomy within a multipolar order.[ii]
Tokyo’s quest for strategic autonomy has necessitated a radical pragmatism in the Middle East supply chain crisis triggered by the closure of the Strait of Hormuz. Following the closure of this route, on which Japan is 94% dependent, its decision to resume Russian oil imports via Sakhalin-2 by utilizing U.S. sanctions exemptions has exposed the limits of the West’s isolation strategy. While this move confirms the rationale of Mitsui and Mitsubishi to protect their assets, it also proves that Tokyo has suspended its value-based rhetoric in the face of an energy threat and is acting with a realpolitik survival instinct.[iii]
This energy necessity has also brought diplomatic concessions in its wake. According to reports from Chinese and Russian media on May 5, Japan—which had reduced contacts to a minimum due to sanctions—offered Moscow official guarantees that it would not supply weapons to Kyiv, despite easing its arms export restrictions; this is a realpolitik concession imposed by the energy crisis. Analysts emphasize that this sudden strategic retreat stems from the disruption of the Middle East supply chain and that the guarantee of a weapons embargo against Kyiv is, at its core, a “strategic surrender in exchange for Russian oil.” [iv]
In contrast to diplomatic assurances, the steps taken on the ground represent the riskiest aspect of Tokyo’s strategy of ambiguity. Japan’s relaxation of its arms export ban, enabling Terra Drone to partner with Ukrainian firms WinnyLab and Amazing Drones to build a “layered air defense system” using the Terra A1 and Terra A2 UAVs, represents the most concrete commercial-military transformation of the pacifist doctrine on the ground. This move, proceeding in parallel with defense spending triggered by threats from China and North Korea, continues despite Russia’s strong protests and the summoning of the Japanese ambassador to the Ministry of Foreign Affairs in Moscow; it demonstrates Tokyo’s determination to integrate directly into the Western military-industrial supply chain.[v]
This disconnect between the field and diplomacy has led to direct warnings in bilateral relations. Indeed, on May 5, 2026, a meeting took place between Russian Deputy Foreign Minister Mikhail Galuzin and Muneo Suzuki, a member of the House of Councillors of the Japanese Parliament. According to a statement by the Russian Ministry of Foreign Affairs, during the meeting—which addressed international issues including Ukraine—the Russian side conveyed its concerns regarding Tokyo’s policy of providing military-technical assistance to Kyiv, emphasizing that this approach would harm the future of bilateral relations.[vi]
Efforts are being made to ease this deadlock in official channels through backchannel diplomacy by figures like Suzuki. Suzuki, whose visit to Moscow has been confirmed, stated that the sanctions imposed during former Prime Minister Fumio Kishida’s tenure harmed national interests, and expressed his aim to find a way out of the tense situation and return to the friendly relations of the Shinzo Abe era. Suzuki, who has faced criticism in the past, continues to insist on the signing of a peace treaty and the strengthening of ties.[vii]
Ultimately, Suzuki’s contacts with Russian Deputy Foreign Minister Andrey Rudenko represent an effort to keep unofficial channels open amid the current lull in relations. The fact that Moscow has signaled its willingness to allow a potential foreign ministers’ meeting—the first since September 2021—on the sidelines of the ASEAN summit in the Philippines this July, but has conditioned this on Tokyo abandoning its “hostile policies,” clearly reflects Moscow’s strategy of asymmetric pressure through the frozen treaty.[viii]
It is foreseeable that Tokyo’s policy of “calibrated strategic ambiguity” and “controlled tension” toward Moscow will evolve in the near future along three main scenarios, depending on shifts in geopolitical fault lines. In the first scenario, should the global energy crisis centered on the Strait of Hormuz become chronic, the Tokyo administration may prioritize national security by risking diplomatic friction with the U.S. to expand sanctions exemptions. It could institutionalize a “oil-for-pacifism” exchange within the Western alliance to establish a temporary energy-based “compromise” with Russia. In the second scenario, which carries a high potential for escalation: If the activities of Japanese defense industry firms like Terra Drone in Ukraine violate the Kremlin’s red lines, this could lead to Russia unilaterally suspending supplies for the Sakhalin -2 project or rapidly militarizing the Kuril Islands (Northern Territories), which could undermine Japan’s pursuit of strategic autonomy and force Tokyo to fully integrate into the Western bloc at a high cost.
In the third and most rational scenario, based on diplomatic negotiations: through “major bargaining” during high-level talks—paved the way by the informal back-channel diplomacy led by Muneo Suzuki and likely to take place on the sidelines of an ASEAN Summit— Japan is likely to secure a commitment from Russia for uninterrupted energy supplies in exchange for guaranteeing restrictions on military-technological exports to Ukraine, and to revive—albeit to a limited extent—the frozen peace treaty process to preserve its diplomatic maneuvering room against the China-North Korea threats in the Asia-Pacific.
Ultimately, Japan’s asymmetric relations with Russia constitute a realpolitik struggle for survival, caught between alliance commitments and ontological survival concerns within a fracturing global order. Tokyo’s continued dialogue with Moscow—driven by energy and national security needs—while integrating into the Western bloc is pushing the limits of its adopted doctrine of “calibrated strategic ambiguity.” It is highly likely that the course of future energy crises, military-industrial practices on the ground, and the outcomes of backdoor diplomacy will test Japan’s strategic autonomy and flexibility.
