Type 4 Grenade

Two Ceramic Grenades

The Type 4 Grenade was a grenade that was used by Japan during World War II.

Description[]

It is approximately the size of a baseball and it is usually made of terra cotta. The grenade had a rubber plug covering the simplistic match-type fuze. It was ignited much like a flare.[1] The grenade detonated after four or five seconds from ignition.

History[]

The Type 4 Grenade was developed because of the shortage of many raw materials, particularly because of Allied bombing raids. Terra Cotta could be mass-produced and the grenade was produced in the thousands. It saw usage on the islands of Iwo Jima, Okinawa, and Leyte in the Philippines.[2]
