U.S. Marines test-fired 12 rockets [1] from a HIMARS mobile rocket system in Japan on May 20, 2026 [2].
The exercise serves as a critical demonstration of military capabilities intended to support the U.S. Pacific deterrence strategy. By conducting live-fire drills in the region, the U.S. aims to signal its operational readiness and commitment to regional security.
The drill took place in the foothills of Mount Fuji [3]. During the operation, the Marines utilized a "shoot-and-scoot" tactic, which involves firing munitions and quickly relocating the launcher to avoid enemy detection and counter-battery fire.
The High Mobility Artillery Rocket System, known as HIMARS, is a highly mobile light multiple rocket launcher. The ability to deploy such systems in the Japanese landscape allows the U.S. military to practice rapid deployment, and precision strikes in diverse terrain.
This specific exercise is described as a rare live-fire event for the system in this location. The deployment of 12 rockets [1] allows the military to verify the system's accuracy, and the effectiveness of the rapid-relocation maneuvers under field conditions.
The U.S. military has increased its focus on mobile assets in the Pacific to counter evolving threats. The use of the Mount Fuji foothills provides a challenging environment that mimics potential real-world operational scenarios — emphasizing the need for agility and speed in modern warfare.

The use of "shoot-and-scoot" tactics with HIMARS in Japan reflects a strategic shift toward greater mobility and survivability in the Pacific theater. By practicing these maneuvers near Mount Fuji, the U.S. is testing its ability to project power quickly while minimizing the risk of its assets being targeted, a necessity in a region characterized by dense geography and advanced adversary surveillance.
