The Intersection of Hunger and Victory: Japanese Logistics and Nutritional Strategy from the Russo-Japanese War to the Greater East Asia War (1904-1945)

The Russo-Japanese War (1904-1905) was Japan's first full-scale foreign war and a test of logistics across land and sea. The war was fought in remote areas such as the Liaodong Peninsula and Manchuria, and the transportation of supplies was heavily dependent on railroads and port facilities. The Japanese, under the leadership of the Army's Food and Tortugage Headquarters, worked hard to supply soldiers with food that was easy to preserve, such as dry hard bread, canned foods, and miso (bean paste).

On the other hand, Russia's inadequate railroad network and long supply lines, as well as delays in adapting foodstuffs to the Asian climate, caused soldiers to suffer from poor physical condition. An interesting anecdote is that the technique of eating soybeans as bean sprouts, which the Japanese brought into the war zone, played a role in maintaining nutrition. Unlike the Russian troops, who suffered from beriberi and scurvy due to vitamin deficiency, the Japanese were able to secure valuable nutrients from the bean sprouts. Bean sprouts were ideal as a "battlefield nutritional source" that could be harvested in a short period of time because they could be easily grown with only water and in the dark.

However, this logistical ingenuity began to falter during World War II. In the Pacific War, supply lines became vulnerable as the front line expanded throughout the Asia-Pacific region. Food supplies were cut off at the front lines in places such as Gadarkanal and Burma, and soldiers wandered through the hells known as "white-bone roads" and "starvation fronts. Malnutrition and malaria were rampant, and there were many battlefields where more people died of starvation than of bullets.

At the time, Japan was highly self-sufficient in food, and there was still a certain amount of surplus in the country. However, the strategic neglect of "food" was a problem. Mentalism prevailed in the army, and unreasonable instructions such as "fight on a handful of rice a day" were given. The neglect of logistical support was one of the factors that turned a tactical victory into a war of attrition and deepened Japan's defeat.

At the same time, the end of the war saw the disruption of rural distribution due to air raids on urban areas, a decrease in imports due to the loss of ships, and the introduction of a rationing system for the entire population, which led to state controls over food, but it was already too late. The Japanese war leadership learned the importance of the words "supply" and "nutrition" at the cost of the lives of the soldiers at the end of the war.

In the shadow of this history, diverse factors such as nutrition, agricultural technology, preservation methods, and psychological warfare are intertwined. War is not only a battle of ammunition, but also a battle of nutrition and supply, where a grain of grain or a sprout can make the difference between victory and defeat.
