The Shitotsubakurai (Japanese: 刺突爆雷) or lunge mine was a suicidal anti-tank weapon developed and used by the Empire of Japan during the Second World War.

[1] The handle was connected to the mine body with a length of tubing through which it could slide once the safety pin was removed and the copper shear wire broken by impact with the target, at which point the steel striker at its end would be driven into the detonator.

The three metal legs welded to it were 6 inches (15 cm) long, intended to ensure the proper stand-off distance for the shaped charge to achieve maximum penetration.

The Intelligence Bulletin reported in March 1945 that United States forces met this weapon for the first time in Leyte Island, The Philippines, during the 1944 invasion.

"[1] In Vietnam, it became an icon of the First Indochina War, specifically the Battle of Hanoi, during which Platoon Leader Nguyen Van Thieng tried to use it; however, the bombs failed to explode.
