Some severed heads (namakubi)


Some recent severed heads I’ve tattooed
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. The sword was expected to be used upon the slightest sign that the practitioner might yield to pain and cry out—avoiding dishonor to him and to all partaking in the privilege of observing an honorable demise. As skill was involved, only the most trusted warrior was honored by taking part. 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 Sugitani Zenjubō (ja) (杉谷善住坊), who attempted to assassinate Oda Nobunaga, a prominent daimyō, in 1570. After being caught, Zenjubō was buried alive in the ground with only his head out, and the head was slowly sawn off with a bamboo saw by passers-by for several days (punishment by sawing; nokogiribiki (ja) (鋸挽き).[36] These unusual punishments were abolished in the early Meiji era. This horrific scene is described in the last page of James Clavell’s book Shogun.

Oni in hell

Dai-jounetsu Jigoku, the hell of great burning, is much the same as Jounetsu Jigoku, only much hotter. The suffering here is equivalent to ten times more than all of the higher hells combined. This plane of hell is reserved for sinners who have committed all of the crimes listed previously in addition to physical crimes against Buddhist clergy — for example, raping a nun. The screams of the tortured souls here are so terrible that they can be heard up to 24,000 miles away. The power of this hell is so great that those who are to be sentenced here begin to feel their suffering up to three days before they actually die. The punishment on this level of hell lasts one half of an antarakalpa — a unit of time in Indian cosmology that is so unfathomably long that it defies mathematical description.
Mugen Jigoku, the hell of uninterrupted suffering, is the eighth and deepest circle of hell. It is reserved for the worst of the worst — murders of their own parents; killers of saints; those who have betrayed every single Buddhist precept. The souls down here are so hungry and thirsty that they tear apart their own bodies and drink their own blood in a useless attempt to ease their suffering. Words literally cannot describe how awful this hell is; if Mugen Jigoku were ever accurately described, both the reader and the writer would die from the sheer horror of it. It is so deep that it takes 2000 years of falling, nonstop, at terminal velocity, for a soul to descend all the way into this hell. Some say that those who are sent here never come back, while others say that the term of punishment here lasts one full antarakalpa, after which the soul may reincarnate again; although, even after a soul is finally released from this hell, its punishment is said to continue on into its next lives. 

The side panels have more oni to be added ,the figure in the middle is a demented soul banished to eternal sufferings the belly button has been incorporated as a disembowelling
