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.
The Japanese Army put heavy emphasis on capability and lightweight, insisting that Schneider reduce at least 200kg from the base model before formal adoption.
