Traditional method of female suicide where the person cuts their jugular vein with a knife called a tantō. In this case the suicide victim was a man, a devotee of Japanese culture & weapons.

Italy: rare case of suicide, in which the victim was a male devotee of Japanese culture and weapons. He was found dead in his bathtub with a deep slash in the right lateral-cervical area, having cut only the internal jugular vein with a tanto knife, exactly as specified by the jigai ritual.

A 58-year-old man was found dead in his bathtub, with a clearly visible slash in the right lateral-cervical area. On the bathtub rim, there was a steel weapon, a knife of the tanto¯ variety (Fig. 1), whose blade was 30 cm in length. Further inspection of the house discovered 2 katana swords and some kaiken knives placed on a rail, in addition to several books describing Japanese culture and traditions.

The external examination of the body revealed on the right lateral-cervical region a deep slash (4 cm), with no interruption, which affected the skin and soft tissue below (Fig. 2).

The autopsy of the neck revealed that the aforementioned uninterrupted slash became even deeper, ultimately causing a partial severing of the internal jugular vein, although the arterial vascular structures remained intact (Fig. 3).

Inspection of the heart revealed a vast whitish pale area, affecting the posterolateral wall of the left ventricle at the level of the third lower average. The appearance of this area was consistent with previous infarct episodes (Fig. 4).

The coronary arteries showed significant luminal narrowing of two thirds at the level of the anterior descending and circumflex, whereas the posterior coronary artery was completely occluded.
The examination of the remaining organs appeared devoid of elements worthy of note with the exception of a visceral diffuse pallor, compatible with a framework of hemorrhagic shock as well as the rest of the scarcity of phenomenology hypostatic. The toxicological examination was completely negative.
Considering all the data revealed by the postmortem examination, it was possible to attest that death was caused by critical hemorrhagic shock in a subject with reduced coronary reserve.
