The Type 91 10 cm howitzer (九一式十糎榴弾砲, Kyūisshiki Jyūsenchi Ryūdanhō) was a 105 mm (4.13 in) howitzer used by the Imperial Japanese Army during the Second Sino-Japanese War and World War II as the standard Japanese light howitzer. The Type 91 10 cm howitzer was designed by the French company Schneider during the late 1920s per Japanese Army requirements and was considered to be light, robust and reliable. [7] Type 91 howitzers were issued to artillery regiments where they would supplement 75mm field guns. [8] The Type 91 number was designated for the year the gun was accepted, 2591 in the Japanese imperial year calendar, or 1931 in the Gregorian calendar.[9]
