How a Japanese General used his American education to defend Iwo Jima

In short: Tadamichi Kuribayashi was an unlikely adversary for the United States. A former military attaché who lived in America, drove a Chevrolet, and befriended U.S. officers, he understood the American national character. When ordered to defend Iwo Jima, he applied that knowledge to create a brutal, unconventional, and devastatingly effective defense.

Born into a samurai family in 1891, Tadamichi Kuribayashi was a literary enthusiast who excelled in English and initially dreamed of becoming a journalist. His career took a decisive turn when he studied in the United States from 1928 to 1930. Living in cities like Buffalo and Washington, D.C., and training at Fort Riley, he gained a deep appreciation for American industrial capacity. He famously remarked that American industry could be fully mobilized for war with the push of a single button, a reality he believed Japan could not overcome.

Despite his private conviction that war with the United States was a no-win situation, Kuribayashi was assigned to defend Iwo Jima in June 1944. Recognizing that he could not defeat the overwhelming American force, he pivoted to a strategy of attrition. He rejected the traditional, suicidal 'banzai' charges, which he viewed as a waste of life. Instead, he ordered his men to abandon the beaches and retreat into a massive, honeycombed network of over 18 kilometers of tunnels and 5,000 caves. This underground fortress allowed his garrison to endure heavy shelling and inflict maximum casualties on the invading Marines.

Kuribayashi’s goal was to drive up American casualties to force a shift in public opinion toward a negotiated peace. His tactics were so effective that the U.S. Marine Corps, which expected to capture the island in five days, was held at bay for 36 days. Even as his supplies of water and ammunition vanished, he maintained strict discipline among his men. He was likely killed in action on 26 March 1945, while leading a final, organized assault. His body was never identified, as he had removed his insignia to fight alongside his soldiers as an equal.
