Hiromichi Yahara (Japanese: 八原博通, October 12, 1902 – May 7, 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.
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 (jikyūsen, 持久戦), 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 method, 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.
When Lieutenant General Cho and Lieutenant General Mitsuru Ushijima decided to commit ritualistic suicide in Mabuni caves, Yahara requested permission to commit seppuku alongside them, but Ushijima refused, telling him "If you die there will be no one left who knows the truth about the battle of Okinawa. Bear the temporary shame but endure it. This is an order from your army commander."[1] Cho instructed Yahara to make his way through the American lines to northern Okinawa and report to Tokyo on what had happened, and gave him 500 yen for the journey.[2]
After the two generals had committed suicide, Yahara hid with several other staff officers in a small cave whose entrance they had blocked with stone and waited for the opportunity to escape. After hearing American troops drilling into the rock above them they relocated to another cave before deciding to split up. Disguising himself as a civilian, he made his way down Mahuni Hill and eventually joined two other soldiers, the three of them joining a large group of approximately 50 civilians sheltering in a cave. The group was discovered by the Americans who following an air attack on the cave convinced the group to surrender. Yahara led them out and was mistakenly judged to be a Japanese English teacher. He was taken to a holding camp before being taken to a house on Chinen Peninsula which he shared with 30 other civilian refugees. He later joined a work detail before eventually three weeks after his escape from the 32nd Army headquarters his true identity was discovered by the U.S. military. Now a prisoner of war with privileges due to his rank as having been the third highest ranked Japanese officer on the island, he was transferred to 10th Army headquarters where he was interrogated.
Following the end of the war Yahara was repatriated back home to Japan in January 1946.[2]
After the war Yahara wrote his account of the battle. His Okinawa Kessen (Decisive 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.
