 In the late Sengoku period, decapitation was performed as soon as the person chosen to carry out seppuku had made the slightest wound to his abdomen.Decapitation (without seppuku) was also considered a very severe and degrading form of punishment.One of the most brutal decapitations was that of (杉谷善住坊), who attempted to assassinate Oda Nobunaga, a prominent "daimyō", in 1570.
