Japanese Prime Minister Takahashi proposed an energy-cooperation framework at the G7 summit to address disruptions to oil supplies [1].
This move comes as the closure of the Hormuz Strait threatens global energy stability and the safety of commercial shipping. Japan, heavily dependent on imported fuel, is seeking a coordinated international response to ensure the flow of oil and the security of merchant vessels.
During the summit, Takahashi joined a joint statement focused on merchant-ship safety and mine-clearance operations [1]. The G7 online meeting, held on the night of June 30, 2026 [2], resulted in a joint statement on energy security [2]. This agreement calls for additional oil stock releases to stabilize the market [3].
Beyond diplomatic agreements, the Japanese government is considering the possible deployment of the Self-Defense Forces to the region [1]. Such a move would represent a significant escalation in Japan's maritime security role.
Finance Minister Katayama said production needs to increase, saying, "Production countries should refine and release oil beyond full throttle" [4].
Parallel to these security measures, Takahashi is seeking a separate meeting with U.S. President Donald Trump [1]. The goal of this bilateral discussion is to align strategic interests regarding the energy crisis and regional stability in the Middle East.
These efforts reflect a broader Japanese strategy to mitigate the economic impact of the Hormuz Strait closure while strengthening ties with G7 partners and the U.S. administration.
“Japan is seeking a coordinated international response to ensure the flow of oil.”
Japan's push for a G7 energy framework and the potential deployment of the Self-Defense Forces signal a shift toward a more proactive security posture. By linking energy stability to military readiness and bilateral diplomacy with the US, Tokyo is attempting to insulate its economy from geopolitical volatility in the Hormuz Strait.
