切腹と短刀の作法
Seppuku existed from the medieval period as a mode of self-inflicted death among warriors, but was institutionalized as a formal punishment in the Edo period, and its ritualized procedure became established around the Kyōhō era in the early 18th century. The tantō was used with its blade wrapped in many layers of paper so that only the tip was exposed, and the kaishakunin bore the role of shortening the suffering.

Description
Establishment of Seppuku as an Institution
Seppuku had been practiced since the medieval period as a form of self-inflicted death among samurai. When it was established in the early modern period as a punishment for samurai, it was developed into a ceremony accompanied by ritual procedure. In scholarship, the leading view is that the stylized seppuku procedure became established in the early 18th century, around the Kyōhō era.
Blade Used and Its Handling
The blade used for seppuku was a tantō about kyūsun-gobu (approximately 29 cm) in length. In actual execution, the widely practiced method was to remove the hilt, wrap the blade in several layers of hōshogami, bind it with paper cord so that it would not move, and use it with only the tip exposed. This is said to have been a device to keep the person performing seppuku from thrusting in too deeply by mistake. From the mid-Edo period onward, an abbreviated form called ōgibara (fan seppuku) also came into use, in which a wooden sword or fan was used formally in place of the tantō.
The Role of the Kaishakunin
Cutting the abdomen alone meant prolonged suffering before death, so a kaishakunin attended the seppuku and, immediately after the cut, took on the role of shortening the suffering by beheading the condemned with a long sword (tachi). Kaishaku required a high level of cutting skill, and a failure brought dishonor upon the kaishakunin's own name.
Social Context and Influence on Later Generations
Seppuku became established in samurai society as a stylized form of preserving honor. Incidents such as the seppuku of the 46 Akō rōnin (1703) were widely passed down as Chūshingura through kabuki and jōruri. In the Sakai Incident of the Bakumatsu period (1868), seppuku was carried out in the presence of French men, a rare occasion on which its procedure was conveyed overseas. As an institution that symbolizes the Japanese view of life and death and the spirit of bushidō unique to Japan, it has left a strong impression both within Japan and abroad.
Characteristics of This Era
- Dimensions of the tantō used ── a tantō of kyūsun-gobu (about 29 cm) in length was regarded as the standard
- Paper-wrapping procedure ── the hilt was removed, the blade was wrapped in many layers of hōshogami and bound with paper cord, and a handling method exposing only the tip was widely practiced
- Ōgibara (fan seppuku) ── from the mid-Edo period onward, an abbreviated form was also seen in which a wooden sword or fan was used formally in place of the tantō
- Role of the kaishakunin ── an assistant who, immediately after the cut, beheaded the condemned with a long sword to shorten suffering. A high level of skill was required
