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 of the period, it was influenced by Schneider designs and was considered to be light, robust and reliable. [5] Type 91 howitzers were issued to artillery regiments where they would supplement 75mm field guns. [6] 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.[7]
