Banzai charge or Banzai attack (banzai totsugeki) is the term that was used by the Allied forces of World War II to refer to Japanese human wave attacks and swarming staged by infantry units. This term came from the Japanese battle cry tennōheika banzai, and was shortened to banzai, specifically referring to the tactic used by the Imperial Japanese Army during the Pacific War. This tactic was used when the Japanese commanders of infantry battalions foresaw that a battle was about to be lost, as a last ditch effort in thwarting Allied Forces. The banzai charge is considered to be one method of gyokusai, a suicide attack, or suicide before being captured by the enemy such as seppuku. The origin of the term is a classical Chinese phrase in the 7th-century Book of Northern Qi, which states "丈夫玉碎恥甎全", "A true man would [rather] be the shattered jewel, ashamed to be the intact tile." Among the rules there existed a code of honor that was later used by Japanese military governments. With the revolutionary change in the Meiji Restoration and frequent wars against China and Russia, the militarist government of Japan adopted the concepts of Bushido to condition the country's population to be ideologically obedient to the emperor. Impressed with how samurais were trained to commit suicide when a great humiliation was about to befall them, the government taught troops that it was a greater humiliation to surrender to the enemy than to die. The suicide of Saigō Takamori, the leader of old samurai during the Meiji Restoration, also inspired the nation to idealize and romanticize death in battle and to consider suicide an honorable final action. During the Siege of Port Arthur human wave attacks were conducted on Russian artillery and machine guns by the Japanese which ended up becoming suicidal. Since the Japanese suffered massive casualties in the attacks, one description of the aftermath was that "[a] thick, unbroken mass of corpses covered the cold earth like a coverlet". In the 1930s, the Japanese found this type of attack to be effective in China.
