Japan's Six-Six Fleet and local sea control

Japan could not match the world's largest fleets ship for ship, so it built a force intended to demand substantial overmatch from any attacker. Six strong battleships and six armored cruisers combined quality, mutual support, and uncertainty for an opponent calculating how many capital ships would be needed. An attacker might therefore need fourteen to sixteen battleships to neutralize both groups safely. This differed from both the Jeune École and a single-opponent Risk Fleet because Japan sought to make itself a hard regional target for any great power. The strategy sought local dominance in the East China Sea and western Pacific, backed by nearby infrastructure rather than global power projection. It was deterrence rooted in Japan's geography and resources rather than a copy of another navy's fleet model.
