Japan eventually bought a license for domestic production, with the type seeing notable service during the Russo-Japanese War. Japanese gun designer Kijirō Nambu would later modify the domestic Hotchkiss M 1897 heavy machine gun to better meet Japanese requirements, to include lessons learned following the conclusion of the Russo-Japanese War. This effort would result in the adoption of the domestic Type 38 heavy machine gun in 1907. The Type 38 heavy machine gun would first see action in Qingdao, China during World War I. The Type 38 heavy machine gun was still in service at the time of the Marco Polo Bridge incident in 1937. Kijirō Nambu would further modify the Type 38 heavy machine gun in 1909, focusing on improving dissipation and durability. This would result in the Type 3 heavy machine gun, entering service in 1914 and first seeing action in the Japanese intervention in Siberia in 1919. During the 1930s, the Type 3 heavy machine gun would see wide-scale use in Manchuria and China during the Second Sino-Japanese War. The Type 3 tripod could be used as an anti-aircraft mounting, and special anti-aircraft sights were provided.

• Chile: Chile bought several hundred Type 3 machine guns in 7×57mm Mauser as Modelo 1920.
