Type 94 75 mm Mountain Gun

The Type 94 75 mm Mountain Gun was a mountain gun used as a general purpose infantry support gun by the Imperial Japanese Army during the Second Sino-Japanese War and World War II. It superseded the Type 41 75 mm Mountain Gun to become the standard pack artillery piece of Japanese infantry divisions. It was superior to Type 41 in range and in weight. The Type 94 number was designated for the year the gun was accepted, 2594 in the Japanese imperial year calendar, or 1934 in the Gregorian calendar.

Combat experience with the Type 41 Mountain Gun during the invasion of Manchuria indicated to the Imperial Japanese Army General Staff that the existing primary mountain gun lacked not only in firepower and accuracy, but also was not as easily transportable under difficult terrain as had been hoped. The Army Technical Bureau was assigned a project to develop a replacement in 1931. The first prototype was tested in 1932, and the design released for production by September 1934 as the "Type 94". However, plans to re-equip all artillery regiments with the new weapon were continually postponed due to budgetary priorities.

Type 94 75 mm Mountain Gun was used extensively in Manchukuo during the Pacification of Manchukuo, and during the Second Sino-Japanese War. It was also assigned to units in the Southern Expeditionary Army and was sited in defensive positions on islands throughout the Netherlands East Indies and the South Pacific Mandate. It was one of the most common weapons encountered by Allied forces towards the closing stages of the war.

Chinese copies of the Type 94 were used by the North Koreans during the Korean War.

Type Light, highly mobile pack artillery weapon suitable for horse or motor vehicle.
