This is a complete set of ten original volumes of the. “Revised Civil Defense Member Handbook Draft” (Bogo Dantai Hitsuyo Soan). Under the supervision of the. Eastern Defense Headquarters of the Imperial Japanese Army. Unlike frontline military manuals, these books were created to train members of Japan’s. An organization responsible for protecting civilians in the event of air raids and other wartime emergencies. Rescue and first aid. In many ways, the organization combined roles similar to today’s volunteer fire departments, emergency response teams, and civil defense organizations. The set contains all ten sections covering every branch of Civil Defense operations. Numerous illustrations demonstrate first-aid procedures, casualty evacuation, stretcher carrying techniques, hemorrhage control, and emergency response methods, showing that these manuals were intended for practical field training rather than theoretical study. The preface explains that the work was revised with the cooperation of the. Army Science Research Institute. And was intended as an official operational guide for Civil Defense personnel during Japan’s expanding wartime mobilization. Several volumes bear a purple ownership stamp reading. Nagayama Pharmacy, Yorozu-machi, Tochigi. This is believed to be the stamp of a former owner or institution that once used these manuals. Because pharmacies often participated in emergency medical support during the period, the stamp adds an additional layer of historical interest, although its exact history is unknown. Complete sets like this rarely survive. Since each booklet was intended for practical use by different Civil Defense units, many were discarded or separated after the war. Finding all ten original volumes together is increasingly uncommon. This collection offers an exceptional glimpse into Japan’s home-front civil defense system immediately following the outbreak of the Second Sino-Japanese War in 1937 and represents an important historical resource for collectors of WWII militaria, civil defense, and wartime social history. Please examine the photographs carefully for overall condition, including age-related wear, foxing, stains, and other signs of use. Own a Piece of History. International Buyers – Please Note.

This is an original Imperial Japanese Army military handbook titled. (“What Every Logistics Soldier Should Know”), supervised by the Army Inspector General of Military Education. The cover is marked. Army Inspector General of Military Education Supervision. This was a compact educational handbook intended for soldiers serving in the Japanese Army’s logistics and transport branch. What Was the Army Inspector General of Military Education? The Army Inspector General of Military Education was one of the most influential organizations within the Imperial Japanese Army. It was responsible for military doctrine, officer education, training programs, and the preparation of official instructional materials used throughout the army. Because this handbook was supervised by that organization, it was not simply a commercial publication but an official educational reference reflecting Imperial Japanese Army training standards. The Forgotten Soldiers of the Japanese Army. The Shichohei (Logistics Corps) were responsible for transporting food, ammunition, equipment, uniforms, and horses to frontline units. In modern terms, they were the military logistics and supply branch. Interestingly, logistics troops often received less prestige than combat arms within the Japanese military culture. A famous wartime saying even mocked them as. Shichohei are not real soldiers. History ultimately proved otherwise. Many military historians consider Japan’s chronic logistical weaknesses to be one of the major factors contributing to its defeat during the Pacific War. As supply lines collapsed, entire units suffered from starvation, ammunition shortages, and lack of equipment. This handbook therefore represents a rarely preserved glimpse into the branch responsible for sustaining the Japanese Army. Imperial and military flags. Orders, decorations, and medals. Army uniforms and equipment. Logistics and transport training. Several attractive fold-out color plates illustrate military insignia, decorations, flags, and uniforms, making this both a practical military handbook and an excellent research reference. Why It Is Scarce. Most Japanese military instructional materials were discarded or destroyed after 1945. Pocket reference books such as this were heavily used by soldiers and rarely survived in good condition. Furthermore, while infantry, aviation, and armored units are widely collected today, surviving materials relating specifically to the Japanese Army’s logistics branch appear much less frequently on the market. An excellent item for collectors of Imperial Japanese military history, military education, uniforms, insignia, and logistics history. Own a Piece of History. International Buyers – Please Note.
