Tokyo is weighing the possibility of purchasing Russian crude oil following a recent U.S. Waiver allowing such transactions under certain conditions, a move that underscores the complex geopolitical calculations facing Japan as it navigates energy security and international alliances. This potential shift comes as Japan seeks to diversify its energy sources and mitigate economic risks, even as it maintains its commitment to sanctions against Russia following the invasion of Ukraine.
The U.S. Government granted a limited waiver to allow Japan to continue importing Russian oil, specifically from the Sakhalin-2 project, in which Japanese companies hold stakes. This decision, reported by multiple sources, acknowledges Japan’s energy needs and the potential disruption to its economy if access to this oil supply were abruptly cut off. The waiver is reportedly contingent on Japan ensuring that it does not contribute to Russia’s war effort and that the price paid for the oil remains within the G7-imposed price cap of $60 per barrel Reuters.
Rising Tensions and Regional Dynamics
Japan’s consideration of Russian crude occurs against a backdrop of escalating tensions in the Asia-Pacific region, particularly concerning China’s growing military assertiveness and its increasingly close relationship with Russia. Recent joint military exercises between Russia and China, including air patrols near Japan, have raised concerns in Tokyo and prompted Japan to scramble fighter jets to monitor the activity CNN. These patrols involved Russian Tu-95 nuclear-capable strategic bombers and Chinese H-6 bombers, along with fighter jets, operating in areas near Japanese territorial waters.
A former Chinese diplomat, Wu Hailong, has warned that Japan is becoming a “most serious and direct” threat to both China and Russia in the region, citing Japan’s historical actions and perceived lack of remorse for its wartime aggression South China Morning Post. This sentiment reflects a growing narrative in both Beijing and Moscow that Japan is actively working to undermine their interests.
Joint Military Exercises and Submarine Warfare Simulations
The deepening military cooperation between Russia and China extends beyond air patrols. In August 2025, the Russian Navy and the People’s Liberation Army Navy (PLAN) conducted joint naval drills in the Sea of Japan, simulating attacks on enemy submarines and amphibious ships, and rehearsing submarine rescue operations USNI News. These exercises demonstrate a coordinated effort to enhance their combined military capabilities and project power in the region.
The Sino-Russian Alignment and its Impact on Japan
Beyond military cooperation, China and Russia have similarly aligned on historical narratives related to World War II, a development that has further strained relations with Japan The Diplomat. This shared interpretation of history often portrays Japan as an aggressor and downplays its post-war efforts at reconciliation. This alignment generates real geopolitical effects, influencing regional perceptions and potentially exacerbating existing tensions.
The potential for Japan to increase its reliance on Russian energy resources, even with a U.S. Waiver, adds another layer of complexity to these dynamics. While the waiver is intended to mitigate economic disruption, it could be viewed by China and Russia as a sign of wavering commitment to the international sanctions regime. The situation is further complicated by existing tensions between China and Japan, particularly concerning territorial disputes and historical grievances.
What to Watch Next
The coming months will be crucial in determining Japan’s energy policy and its broader strategic alignment. Tokyo will demand to carefully balance its economic interests, its security concerns, and its commitment to international norms. Further developments to watch include the extent to which Japan utilizes the U.S. Waiver, the response from China and Russia to any increased purchases of Russian crude, and the evolution of the military relationship between Beijing and Moscow. The ongoing diplomatic efforts to address the war in Ukraine will also play a role, as any resolution could impact the sanctions regime and Japan’s energy options.
