In accordance with the Bushido code, which held honor above all else, a samurai would perform seppuku to avoid capture or as punishment for breaking this sacred code.

The earliest written cases of actual seppuku being performed were in the story of the 1156 Hōgen Rebellion. In this story, warrior Minamoto no Tametomo was said to have reacted to defeat by cutting his own stomach open.

By the middle of the 19th century, seppuku was on the decline along with the samurai way of life. However, it would still be roughly 100 years before its practice had all but been phased out of Japanese culture.

"Seppuku" is translated as "stomach cutting" and would be performed with a tanto, a short dagger.

As with all things related to seppuku, how the tanto was inserted into the gut was carried out in a specific way.
The blade would be thrust into the left side of the belly and pulled to the right with a sharp upward cut at the end.

Prior to the 17th century, the practice was less formal and often resulted in a slower and more painful death as participants bled out.
Around 1700, a helping-hand was incorporated with the addition of a kaishakunin or "second." This person's job was to use a sword to lop off the head of the samurai to deliver a quick death after the samurai had committed seppuku and returned his dagger to its sheath. Wikimedia Commons

The kaishakunin was not supposed to fully sever the head, but leave it still slightly attached at the throat. Failure to do so earned one a bad reputation.

A modified version of seppuku would occasionally be used as a form of protest against the actions of a ruler.
Known as kanshi, this version would see the samurai commit the act and then quickly bandage the wound. He would later appear before his lord and state his grievances before removing the bandage to expose the mortal wound.

Three decades before the seppuku of Isao Inokuma, Japanese novelist Yukio Mishima committed the act after a failed coup d'état, intended to restore the powers of the emperor, at a military base in Tokyo (pictured, on November 25, 1970).Bettmann/Contributor/Getty Images

On November 25, Mishima and five uniformed followers charged in to the Ichigaya Station of the Japanese Ground Self-Defense Force, slashed at soldiers who tried to stop them and took over the commanding officer's offices.
Appearing on the balcony of the building, Mishima delivered a speech to 2,000 soldiers who surrounded it. "Japan's present politics are full of corruption," he said, closing his speech with the war cry of the old Japanese armed forces: "Tenno Banzai" ("long live the emperor"). He then disappeared into the building and committed seppuku.Bettmann/Contributor/Getty Images

Seppuku was an incredibly ritualistic process and involved the samurai going through a number of preparations before committing the act.
One of these was writing his death poem, which was supposed to be eloquent and attest to their emotions, but not directly mention death.

Wives of samurai had their own suicide ritual known as jigai. Carried out in a very similar way with a knife to the belly, women would perform this if their husbands had carried out seppuku or if capture by an an enemy was imminent, so as to prevent rape. Wikimedia Commons

When carried out as punishment, seppuku was not typically a solitary act and was performed in front of one's peers in the garden area of a temple.
The participant would be properly groomed and bathed and dressed in white to symbolize purity.

A servant would typically place a small wooden table in front of the participant that would be set with a sake cup, tanto, and a piece of paper for writing the death poem.
Even the way in which the sake was consumed was of the utmost importance. The sake would be consumed in two drinks of two sips each. One sip would show greed, and three or more would show hesitation. The total of four sips, or shi, would symbolize death. Wikimedia Commons

Seppuku: Inside The Ancient Samurai Suicide Ritual
View Gallery
The Japanese samurai tradition of Seppuku is one of the grisliest and most painful ways to end one's life. The practice involved a highly ritualized process of essentially disemboweling oneself with a dagger and either bleeding out or having a peer finish the job by beheading.
The centuries-old practice was once common in Japan's military and it wasn't until World War II that it seemed to finally be put to rest. Like the traditions of many Old World cultures, the dying out of Seppuku was the result of Japan being forcibly opened up to the outside world during the 19th century.
Before then, Japan had been closed off from much of the Western world with only occasional contact with the Chinese and Dutch trade ships. It wasn't until Europeans and Americans eventually forced their way into trading with Japan that its upheaval into modern society began to occur. During this time, the Japanese government began to reform and was met with resistance from the samurai class.
The killing of foreigners or those who did business with them by samurai wasn't all that uncommon. And in 1863, when Emperor Kōmei issued an order to "expel all barbarians" (Westerners), the samurai gladly did the expelling with their katanas.
This led to an incident in 1868 when samurai soldiers killed 11 unarmed French sailors who were in the coastal town of Sakai to trade. Seeking justice, Japan's French consul, Léon Roches, insisted that the samurai be executed.
Roches had assumed that the samurai would be executed by beheading or firing squad and sent one of his captains, Bergasse du Petit-Thouars, to witness the execution. What du Petit-Thouars saw instead was samurai marching out and performing the old Japanese suicide ritual of seppuku one by one, followed by a particularly poor assist from their peers at beheading. The event was enough for him to stop the execution of the ordered 20 men at 11 suicides.
The incident drove the point home to Western diplomats in Japan that, for samurai, seppuku was not a deterrent against killing foreigners. An imperial decree was eventually handed down, declaring that samurai who killed foreigners would be stripped of their rank and punished accordingly. This meant that they would not be permitted the honor of ending their life with seppuku.
However, seppuku would see somewhat of a resurgence during World War II when Japanese officers would opt to kill themselves with their swords rather than surrender to Allied forces. But with the Allied forces taking control of Japan and forcing the country to adopt the Constitution of Japan over the Meiji Constitution, Japan went through another cultural upheaval.
The Emperor became only a figurehead and a parliamentary government was put in place, rendering seppuku a tradition that had no place in the Japan that emerged in the second half of the 20th century.
