The Type 4 ceramic grenade was developed in Japan during the closing months of World War II. With much of its industrial infrastructure destroyed by Allied bombing and a growing shortage of raw materials, it was designed as a "last-ditch" hand grenade for defending Japan from a possible Allied invasion. After the war, large numbers of these weapons were acquired by the Yakuza.

In practice, the ceramic grenade acted much like a flashbang grenade; the blast would stun or incapacitate the victims more often than kill them. This allowed the user to temporarily disable his target before entering the room to finish him off.
