During World War II, many countries had standardized fragmentation grenades. The Japanese military initially used the Type 91 series but later repurposed it. In 1937, they introduced the Type 97 with better TNT filling and a delayed detonation. The grenade had a cylindrical shape with a pineapple grip pattern and pull-pin fuse. It was not as effective as other grenades in terms of penetration and had reliability issues. Despite this, it remained the standard grenade for the Japanese Army and Navy until the war's end. The Type 99, introduced in 1939, was an improved version that didn't require threading the striker. It became a rifle grenade known as the "Kiska Grenade" during the Anti-Japanese War.
