This was because in Confucian tradition, bodies were gifts from their parents, and so it was therefore disrespectful to their ancestors to return their bodies to the grave dismembered. The Chinese however had other punishments, such as dismembering the body into multiple pieces (similar to the English quartering). In addition, there was also a practice of cutting the body at the waist, which was a common method of execution before being abolished in the early Qing dynasty due to the lingering death it caused. In some tales, people did not die immediately after decapitation. India
The British officer John Masters recorded in his autobiography that Pathans in British India during the Anglo-Afghan Wars would behead enemy soldiers who were captured, such as British and Sikh soldiers. Japan
In Japan, decapitation was a common punishment, sometimes for minor offences. Samurai were often allowed to decapitate soldiers who had fled from battle, as it was considered cowardly. Decapitation was historically performed as the second step in seppuku (ritual suicide by disembowelment). After the victim had sliced his own abdomen open, another warrior would strike his head off from behind with a katana to hasten death and to reduce the suffering. The blow was expected to be precise enough to leave intact a small strip of skin at the front of the neck—to spare invited and honored guests the indelicacy of witnessing a severed head rolling about, or towards them; such an occurrence would have been considered inelegant and in bad taste.
