Izo's Arrest and Punishment in Kyoto
By late 1863, Izo had drifted away from the Tosa Kinnoto, losing his financial backing along with it. He was now destitute, living hand-to-mouth in the capital and even eventually selling his long sword to survive.
In February 1864, Kyoto police arrested him. He was broke, starving, and homeless. To survive, he had turned to a practice known as oshikari: low-level extortion, shaking down Kyoto merchant houses for money. When interrogated, Izo gave a false name, Tetsuzo, and managed to hold to it long enough that the Kyoto police initially failed to realize they had one of the hitokiri sitting in their cells.
For his crimes, he received a brutal three-part sentence: tattooing, public flogging, and banishment from the city.
The tattoo was the standard corporal punishment for minor crimes — petty theft, swindling, burglary, and fighting. Authorities would forcibly tattoo a specific mark onto the criminal's arm or forehead as a permanent, unerasable criminal record. Each region used its own design, so that anyone who saw it would know exactly where the bearer had been convicted and what they had done. For Izo's crimes in Kyoto, the mark was two upright bars — roughly the width of a thumb and twice as long — tattooed above the elbow.
Flogging (tataki) was another formal punishment of the Edo period, applied only to commoners and ronin, not to samurai, women, or boys under the age of 15. Fifty lashes constituted a light beating; one hundred, a heavy one. It was used for minor crimes such as theft and fighting. The instrument was a bamboo whip called a bokijiri, one shaku and nine sun in length, applied to the shoulders, back, and buttocks while carefully avoiding the spine. Before the punishment began, a mat was laid out and the prisoner stripped and made to lie face down, with four men holding his arms and legs. A counter stood nearby to tally the blows, and in the case of a heavy flogging, the prisoner was given water (and smelling salts, if he had fallen unconscious) after the fiftieth stroke while the beaters rotated for the remainder. The beating was typically carried out in public, before a crowd. For a string of burglaries like Izo's, he would almost certainly have received the maximum: one hundred blows.
By the time the Kyoto authorities were finished with him, Izo's back would have been deeply bruised and perhaps bloodied, even though the punishment was not designed to break the skin, while his arm bore the fresh ink of a common thief's tattoo.
The records show he was also sentenced to formal banishment from Kyoto and its surrounding suburbs. In June 1864, he was escorted to the border gate, where Tosa domain officials seized him, bound him, and placed him under heavy guard for deportation back to his hometown.
When Takechi Hanpeita, who was already imprisoned in Tosa, learned of Izo's arrest, he was furious and deeply ashamed. In letters written from his prison cell to his family, he bitterly complained: "It is better for such a fool to die soon... How his parents must lament over him for returning unashamedly to his hometown."
