Kubi Jikken: Head Inspection in Sengoku Japan

Rooted in the military culture of the Sengoku era, the ritual guaranteed status and reward based on verifiable feats in combat. When a warrior claimed to have slain an enemy, especially one of high rank, the severed head had to be formally inspected. This was not done hastily or without ceremony. The head was first washed, the hair re-tied, and the face adorned with shinigeshō (死化粧)—a form of posthumous grooming traditionally done by women in the warrior's household. Warriors were expected to maintain their appearance even in death, and wearing light incense or cosmetics was not seen as effeminate but honourable.

The actual inspection typically took place at a nearby temple or other solemn site. The commanding general and his retainers, all in full armour, participated not just for security—there was always the risk of a raid to recover an important head—but also as a show of discipline and reverence. The head was presented on a wooden stand (首台 kubi dai). A name tag (首札 kubi fuda) was attached, stating both the identity of the slain and the name of the warrior who had taken the head.

There were clear distinctions in terminology. When the head belonged to a high-ranking commander or noble, the ritual was called taimen (対面), or formal audience. If the deceased was of lower rank, the term michi-shiri (見知) was used. A broader category, kenchi (検知), referred to the heads of important individuals, such as those related to generals or noble houses. While kubi jikken referred initially to the inspection of mid-ranking samurai heads, it eventually became an umbrella term for all head inspections.

The general would not gaze directly at the head. Instead, he turned slightly, glancing with the corner of his left eye while keeping his right hand on his sword. The inspection was swift—never repeated—and followed by symbolic gestures. Offerings of sake and kelp (konbu) were made as if to serve the head itself. Cups were stacked, sake poured twice into each, and the head was eventually turned to face north—associated with the verb nigeru (to flee)—before being cast aside or respectfully buried.

Heads were not merely tokens of victory; they also carried spiritual weight. A calm or serene face (仏眼 butsugan) was considered auspicious. But eyes turned left (左眼 sagan), one eye closed (片眼 katame), or teeth clenched in death (歯噛 hagami) were viewed as signs of bad luck. These interpretations varied—clans like the Takeda (武田氏 ) even reversed the meaning of upward or downward gazes. Heads with ominous features were sometimes given Buddhist rites to appease their spirits and avoid misfortune.

Even after inspection, the treatment of the head was dictated by rank and respect. Some were buried in mounds called kubizuka (首塚), others returned to the enemy side in special containers (kubi oke). The heads of particularly notable enemies, such as those taken by Oda Nobunaga (織田信長) in the 1570s, including Azai Nagamasa and Asakura Yoshikage , were even cleaned and displayed ceremonially. Though modern eyes might see this as cold or barbaric, many contemporaries understood it as a sign of solemn respect. Far from humiliation, the head was treated with dignity, cleansed, named, honoured, and finally released.
