This grenade may be thrown by hand or projected with the 50mm grenade discharger, Model 89. The incendiary filling is contained in brass body which may have a propelling charge on the base. The fuze is identical to the one used in the Type 91 and 97 fragmentation hand grenades.
The steel propellant container is 1 1/4 inches long, 1.02 inches in diameter, and has six perforations in its walls. It is screwed into the base of the body. A perforated plug screws into the base of this container and in a cavity in this is a percussion cap. Two flash holes head through the percussion cap holder to a small quantity of black powder. A perforated steel disc covers the plug and inside the propellant container proper is a copper cup containing flakes of nitrocellulose propellant powder.
