Unwinnable War Inevitable, 1941

From Japan, 1941: Countdown to Infamy, by Eri Hotta (Vintage, 2013), pp. 231-234:

On the morning of August 27, 1941, a group of graduate students at the Total War Research Institute [総力戦研究所, Sōryokusen Kenkyūjo] gathered at the official residence of the prime minister of Japan. The atmosphere was subdued, even gloomy, a mood made even more so by the on-and-off late-summer rain. In a grand chandelier-lit hall, the researchers, whose average age was a mere thirty-three, came face-to-face with the cabinet. From nine o’clock in the morning until six in the evening, and then again the following day, they presented a lengthy report. After careful consideration of an array of ministerial data, and having simulated various diplomatic and strategic situations over the previous six weeks, the group concluded that should Japan go to war with the United States and its allies, Japan would necessarily lose. If such a war occurred, Japan might very well prevail in a few initial battles, but it would then be forced into a prolonged war that would see its resources dwindle and eventually run out.

The researchers making the predictions had had approximately ten years of professional experience before joining the Total War Research Institute. The institute was opened in April 1941 and was loosely modeled on Britain’s Imperial Defence College, where officers and leaders were trained in an intensive one-year program. It was meant to be an elite educational institution that would prepare Japan’s future leaders, both military and civilian, for greatness.

The high aspirations of its founders were never realized. Each ministry sent its top candidate, so the students were the crème de la crème of Japan’s midcareer civil servants. But despite the institute’s prime location in central Tokyo, the building itself was enough to make the hearts of the newly arriving students sink. It was a two-story shanty that looked especially incongruous surrounded by the imposing redbrick buildings of the government district. Many recruits felt they had been dragged down to a lowly student existence.

The researchers liked the institute’s first dean, Lieutenant General Iimura Jo. An amiable man and a formidable linguist fluent in French and Russian, he had lectured at an army academy in Turkey and had translated many strategic documents into Japanese. His magnetic personality attracted some interesting people to give special talks at the institute, including one by Ozaki Hotsumi, [Richard] Sorge’s fellow spy. Still, most students were dissatisfied with the life that had been suddenly forced upon them. They had expected to do high-level research but were instead reduced to attending basic physical education and other unoriginal and often ill-prepared classes.

So a trip to Japan’s central region, starting on June 20, 1941, came as a much-needed breather. The group visited the navy’s flagship, the Nagato, at Ise Bay, where Yamamoto Isoroku was headquartered. Aboard the Nagato and another warship, the Hyuga, both equipped with the navy’s latest technologies, the researchers had special permission to observe maneuvers. Everything seemed to go beautifully. But the visitors were most impressed by the capacity of the ships to simulate torpedo attacks in total darkness with astonishing precision, guided by a lighting system embedded in the torpedo itself.

After the maneuvers, Yamamoto was eager to hear what the visitors thought of his fleet. He called on Higasa Hiroo, who’d come to the institute from the governor-general’s office in Korea. He responded with due deference: “I was impressed with your defense system against submarines, sir. The same goes for your bombing strategies. But I sensed a certain vulnerability to aerial attacks.”

Higasa was quite right. A lesser military man might have been irritated by the young civilian’s impertinence, but Yamamoto instead rewarded Higasa with a bottle of whiskey, by then a prized commodity in Japan. Yamamoto was pleased that Higasa had looked beyond the obvious and spoken frankly, something he felt Japan’s elites were generally incapable of. Yes, those impressive naval ships were not as unassailable as they appeared, and Yamamoto would have been the first to admit it.

The researchers remained with the fleet until it reached Shibushi Bay in southern Japan. (Adjacent to this bay was Kinko Bay, which is shaped remarkably like Pearl Harbor.) It was then that the radio informed them of Germany’s surprise attack on the Soviet Union. That, and the resultant decision to occupy southern Indochina, suddenly made the researchers’ work far more urgent.

Shortly after their return to Tokyo, the researchers were assigned a war game exercise. Each member was given a cabinet role to play in a hypothetical government of a hypothetical country (modeled on Japan). From their respective cabinet positions, they were to participate in a hypothetical war with a hypothetical enemy (the United States) and its allies. The exercise started on July 12; not so far away, Foreign Minister Matsuoka was attending his final liaison conference.

For this total war, the cabinet needed to develop policies covering all areas of military strategy, diplomacy, ideology, and economics. The guidelines presented to the researchers by their instructors noted that “the various plans need to correspond to the changes in both domestic and external situations anticipated in the coming two years.… Your policies need to be devised on a specific monthly basis or on a few-monthly basis.” The researchers were meant to simulate real-world developments as accurately as possible, consulting actual data brought in by various ministers from their home ministries. In the end, this war seemed to be more real than imaginary.

At the start of the war game, Japan was on the cusp of declaring war on the United States. The U.S. and British governments having placed embargos against it, Japan was now completely isolated economically. Therefore, it would have to go farther into Southeast Asia to procure resources by force.

The researchers were uneasy with the premise provided by their instructors. They felt that going into Southeast Asia—most likely the Dutch East Indies—made war with the West inevitable, without giving diplomacy a chance to prevent it. Most cabinet members projected that the country would probably be able to secure the Indonesian oil fields but that the enemy fleet stationed in the Philippines would soon launch an all-out attack on Japanese ships, making the transport of resources impossible and defeating the whole purpose of accessing Indonesian oil. As a result, Japan would be provoked into a larger-scale war with the United States, which the country could ill afford. Most ministers had determined even before the simulation started that such a war would be unwinnable and should not be waged.
