Okinawa

kamikaze success during December and January replaced the darkest despair with the brightest hopes. By 1945 Headquarters had decided that the United States would next strike at Okinawa to seize a base for the invasion of Japan proper, as the four Home Islands were called. It was now believed that the kamikaze corps could greatly improve the chances for a successful defense of Okinawa, and thus perhaps—even probably—prevent enemy landings in the Home Islands. So a plan called Ten-Go, or “Heavenly Operation,” was devised. New armies were to be formed from a reserve of military-age men who had been deferred for essential labor, while a powerful air force built around the kamikaze would be organized to destroy the Americans.

More than four thousand airplanes, both suicide and conventional, would launch an all-out attack, joined by hundreds of suicide motorboats operating from Okinawa and the Kerama Islands and followed by a suicide dash of Japan’s remaining warships, including the mighty battleship Yamato. The air assaults would come from two directions: north from Formosa where the Japanese Army’s Eighth Air Division and the Navy’s First Air Fleet were based, and south from Kyushu, with a more powerful force combining several Army and Navy commands, all under the direction of Vice Admiral Ugaki. On February 6 a joint Army-Navy Air Agreement stated:

In general Japanese air strength will be conserved until an enemy landing is underway or within the defense sphere … Primary emphasis will be laid on the speedy activation, training and mass employment of the Special Attack Forces

(kamikaze)

… The main target of Army aircraft will be enemy transports, and of Navy aircraft carrier attack forces.

On its face this was a bold plan conceived in an atmosphere of the most cordial cooperation. Actually, the only leaders motivated by the same conviction were those who believed that the war could no longer be won. Otherwise, there was a deep divergence: the Navy officers seeing Ten-Go as the last opportunity to score a great, redeeming victory; the Army staffers in agreement that the final battle would be fought not on Okinawa but on Kyushu. Though their views conflicted, their reasoning was logical: the sailors, certain that if airpower could not stop the enemy at Okinawa, neither would it do so on Kyushu; the Army insisting that even on the Philippines the Americans had not yet fought a major Japanese army, and that, shattered and whittled by the suicide-saviors, they could be repulsed in Japan proper. However, all—even the doubters—were convinced that at the very least a severe defeat must be inflicted on the Americans to compel the Allies to modify their demand for Unconditional Surrender.

There was one more consideration, probably more apparent to the Army than the Navy. Bamboo-spear tactics were out. The illogical belief that spiritual power could conquer firepower had spawned that other cause of Japan’s absolute inability to halt the American charge across the Pacific: the doctrine of destroying the enemy invaders “at the water’s edge.” Those nocturnal, massed frontal attacks known as “Banzai charges” had repeatedly been broken in blood, leaving the Japanese defenders so weakened that they were powerless to resist. Now there was a new spirit informing the Japanese Army: defense in depth—as careful as the Banzai was reckless, as difficult for the enemy to overcome as the foolhardy wild Banzai had been easy for him to shatter, and so costly in the attrition of enemy men, machines, and ships as to weary the Americans and thus induce them to negotiate.

Ambush, or the tactics of delay raised to a military science, began on the large island of Biak off the western extremity of New Guinea. It was conceived by Colonel Kuzume Naoyuki, commander of about eleven thousand troops of the defense garrison there. Disdainful of the doctrine of destruction at the water’s edge, he decided instead to allow the Americans to come ashore unopposed so that they would stroll unwarily into the trap he would prepare for them. This would turn the area around the vital airfield there into a martial honeycomb of caves and pillboxes—all mutually supportive—filled with riflemen, automatic weapons, artillery, batteries of mortars, and light tanks. Naoyuki also stockpiled these positions with enough ammunition, food, and water—that priceless liquid was less than abundant on Biak, where the heat and humidity would take a toll equal to enemy gunfire—to sustain his defense for months. Thus, when the 162nd Infantry of the Forty-first Division of the U.S. Army landed on Biak on May 27, 1944, they did indeed move confidently inland expecting little opposition—until they reached that vital airfield. Then, from the lowlying terrain around them and the ridges above, there fell a terrible storm of shot and shell that pinned them to the ground; it was not until dark that amtracks were able to extricate them from the trap.

Thereafter, there was no foolish and furious Banzai by which the Japanese enemy customarily bled itself to death. Biak was a grinding, shot-for-shot battle. Ambush, or delay, was repeated at Peleliu and Iwo Jima, battles that the U.S. Marines expected to be won within days or a week or so but lasted for months, with staggering losses not only in valuable time but in still more valuable life and equipment.

These were the tactics that Lieutenant General Mitsuru Ushijima intended to employ on Okinawa with his defending Japanese Thirty-second Army. After his arrival there in August 1944, he hurled himself into the gratifying task of turning that slender long island into an ocean fortress. In January 1945, he sent his chief of staff, Lieutenant General Isamu Cho, to Tokyo for a review of his defenses. Imperial Headquarters planners were delighted with his preparations, for they dovetailed with Ten-Go. Ushijima’s monster ambush was just the tactic to lure the Americans within range of the suiciders—airborne and seaborne—to be smashed so shatteringly that the Thirty-second Army could take the offensive and destroy them.

Upon his return to Okinawa, Isamu Cho was a happy soldier, thirsting for battle and bursting to tell his chief the good news about Japan’s devastating new weapon of the Divine Wind.

The Japanese Samurai CHAPTER FOUR

To understand the Samurai—a hereditary class of professional warriors peculiar to Japan—it is necessary to understand the history of Nippon. Up until 1853, when the American Commodore Matthew Perry opened Japan to world trade, Nippon had been a hermit kingdom into which no foreigner who valued his life would venture. True, between the founding of the Island Empire in 660 B.C. and the arrival of Perry, there had been a brief interlude of intercourse with the West. This occurred after a storm drove a China-bound Portuguese ship ashore in 1543. Later ships brought Catholic missionaries, among them Saint Francis Xavier, the great Jesuit missionary and a leader of the Catholic Counter-Reformation, who stepped ashore in 1549. Under his influence the population of a large area of the southern island of Kyushu became Catholic Christians. This pleased neither the ruling shoguns (military commanders in chief who had seized power from the emperor) or the Buddhist priests.

The shoguns quite understandably suspected that the Catholic missionaries might actually be advance scouts or spies for the colonizing Catholic powers of Europe. They remembered that after Spanish priests came to the Philippines with Ferdinand Magellan, they were followed by Spanish soldiers who made those islands the possessions of the king of Spain. An uprising of Kyushu Christians was put down with ferocious severity, and in 1617 a persecution of Christians was begun. All Christians, whether foreign or Japanese—Protestant or Catholic—were hunted down ruthlessly, and those who did not recant under torture were executed.

Thereafter Japan sank back into isolation. No one could leave the country under pain of death, and no foreigner enter under the same grim penalty. Nor were oceangoing ships allowed to be built. Every Japanese family was required to register at a Buddhist temple, and interest in Buddhist studies was encouraged. Shinto, the naive nature-and-ancestor worship of ancient Japan, was also revived. Shinto, a Chinese word (significant of Chinese influence on Japanese culture), was based on a simple feeling of reverence for any surprising or awesome phenomenon of nature: a waterfall, a splendid cloud formation, a mountain, a magnificent tree, or even an oddly shaped stone. Places that stimulated such delight or awe became Shinto shrines. At the head of this basically shamanist religion stood a master medicine man: the divine emperor.

Japanese tradition claimed that the imperial family was directly descended from the sun goddess. Actually, this family issued from the Yamato clan, which claimed the sun goddess as its progenitor. During the third and fourth centuries the Yamato clan’s priest-chiefs gained suzerainty and may be said to have unified the country, although without destroying the rights of the other clans. This ruling family, then, could claim an antiquity with which none of the other reigning families of the world could compare. It also could claim the allegiance of its
