Colonel Hiromichi Yahara(八原博通) (1902-1981) was the senior staff officer in charge of operations of the 32nd Japanese Army at Okinawa during the American invasion of that island during World War II.

Defense of Okinawa

Yahara, who had taught strategy at the Army War College, was assigned to Okinawa prior to the anticipated American invasion to organize its pre-invasion strategy. His recommended strategy for fighting the American invaders was to continue to tie up the American military as long as possible in a war of attrition (jikyusen), so that the rumored American invasion of Kyūshū, Japan, would be delayed, thereby allowing Kyushu defenders more time to better prepare their defenses.

Once the Okinawa invasion started, Yahara recommended holding back Japanese forces for as long as possible and using them primarily in a defensive posture, rather than an aggressive one. However, Chief of Staff of the Army, Lieutenant General Isamu Cho, soon became frustrated by the relative inaction of the battlefield, and recommended “banzai” charges at the Americans.

Yahara disagreed with this recommendation, but went along with it. But when it was clear that Cho’s samurai-charge methods were not working, but, rather, causing huge numbers of casualties among the Japanese infantry, along with loss of territory, Cho relented and allowed Yahara to continue to make tactical and operational decisions.

Yahara’s methods, since he did not have the firepower to fight the Americans directly in battle and knew that he could not possibly win, was to fight from caves as long as possible, and then, once the caves were lost, to “retreat and defend” -- time after time -- until there was no longer any room to retreat to.

Yahara escapes

Lieutenant General Cho and Lieutenant General Mitsuru Ushijima, ordered Yahara to escape from the Mabuni caves after they had committed ritualistic suicide. This he did, disguised as a Japanese English teacher. This disguise worked well for him on the island, but eventually he was recognized by the U.S. military and made a prisoner-of-war with privileges due his rank.

Okinawa Kessen

After the war Yahara wrote his account of the battle. His Okinawa Kessen (Battle for Okinawa), first published in Japanese in 1973, was an account of his first-hand experience directing Japanese operations on Okinawa during the invasion.

He died in 1981.

Interrogator comments

“Quiet and unassuming, yet possessed of a keen mind and a fine discernment, Colonel Yahara is, from all reports, an eminently capable officer, described by some POWs as the “brains” of the 32d Army.”
