The Iwo Jima commander who understood American power
He told his family that America was a great power and Japan should avoid fighting it if possible.
Tadamichi Kuribayashi was an Imperial Japanese Army officer and diplomat, unusually familiar among senior Japanese commanders with American society, industry, and military power. On Iwo Jima, he rejected a decisive stand at the beaches and organized a defense in depth from tunnels, caves, and concealed positions, turning an impossible strategic situation into a costly battle of attrition. The defense could not prevent Japan's defeat, but it imposed severe costs on the American landing and occupation while reflecting his effort to avoid wasteful banzai charges and indiscriminate self-destruction by his troops.

Designing Iwo Jima’s Defense in Depth
After arriving on Iwo Jima in June 1944, Kuribayashi oversaw extensive defensive preparations shaped by American air superiority and the island’s terrain. Much of the construction was carried out at night to evade aerial surveillance and attack. Drawing on lessons from the Battle of Peleliu, he prepared a defense in depth based on mutually supporting fortified positions and underground tunnels, rather than trying to defeat the landing force at the beaches. Japanese forces held their fire until the landing beaches were crowded with troops and equipment, then fought through a series of defended zones. Kuribayashi divided the island into five sectors with central reserve areas, and discouraged his subordinates from treating banzai charges as viable tactics, emphasizing delay and inflicting losses instead. The plan could not reverse Japan’s defeat, but it prolonged the battle and imposed heavy casualties on U.S. forces.
