Japan Is Giving the United States a Chance in Asia

Foreign Affairs | David Sacks, Nick Snyder

Japan has rapidly expanded its defense capabilities and regional alliances to reinforce U.S.-led deterrence against China across the Indo-Pacific. Prime Minister Sanae Takaichi declared that a Chinese blockade of Taiwan constitutes a survival-threatening situation, granting Tokyo legal authority for collective self-defense. In response, Beijing restricted heavy rare-earth mineral exports and suspended Japanese seafood imports.

To strengthen operational alignment, Tokyo established a permanent Joint Operations Command in 2025 to coordinate directly with American forces. Japan also dispatched 1,400 troops to joint military exercises in the Philippines, lifting its decades-long ban on exporting lethal weapons to co-produce frigates for Australia. However, Washington delayed the delivery of 400 procurement-allocated Tomahawk cruise missiles and temporarily redeployed its East Asian aircraft carrier strike group to the Middle East. Strategic distraction in Washington threatens alliance cohesion. American delays risk undermining East Asian military posture at a decisive strategic inflection point.

Comment

The bottleneck in delivering 400 Tomahawk cruise missiles to the Japan Ground Self-Defense Force reveals structural fragility within the American defence industrial base. Production constraints at facilities manufacturing key components for the RIM-161 Standard Missile 3 Block IIA demonstrate how domestic U.S. supply chain limits directly constrain allied deterrence postures. Licensing agreements that allow Mitsubishi Heavy Industries to build interceptors internally fail to offset upstream component shortfalls originating in North America.

These delays stem from rigid International Traffic in Arms Regulations frameworks that restrict technical data sharing required for localized Japanese component certification. Without bilateral Streamlined Co-Production Agreements to bypass state-side supply chokepoints, primary contractors in Nagoya remain tethered to delayed sub-tier suppliers in the United States. Expanding Mitsubishi Heavy Industries' final-assembly rights under existing RIM-161 charters provides the primary operational mechanism to prevent Joint Staff munition stockpiles from depleting.

Strategic Question for Discussion

If production constraints at North American component suppliers continue to delay RIM-161 Standard Missile 3 Block IIA deliveries, which industrial mechanism offers the fastest path for Mitsubishi Heavy Industries to achieve self-sustaining co-production without violating International Traffic in Arms Regulations?

The available evidence points toward expanding licensed local manufacturing rights for sub-tier guidance components directly to Japanese prime contractors. Establishing dual-source supply chains within Nagoya would reduce single-point dependency on American production bottlenecks while preserving export control compliance. This shift would allow the Japan Self-Defense Forces to maintain planned interceptor inventory levels independent of third-theater operational diversions.
