According to the Treatise on the Wa People, when the Chinese encountered the Japanese they lived in a land with no cattle, horses, tigers, leopards or sheep. They fought with spears & bows. By the Nara period (710~94) they had begun fighting on horseback. Heian~Kamakura period (794~1333)
Sakanoue Tamuramaro was sent north to fight the Ezo barbarians, and returned to Kyoto victorious having taken 457 heads, captured 150 warriors w/ 85 horses & burned 75 villages. Following that, noble households began emphasizing mounted combat.

The proper way to attach labels to heads taken in battle.
Affix to the left side of the hair
From An Illustrated Guide to Military Affairs
1707 For the head of a warrior monk, the tag should be on the left year.
The tag should list:
Name
Rank
Person who took head

Scene inside an Edo Era prison. The guards basically let the prisoners manage themselves. All the tatami mats have been pulled off the ground (leaving a wooden floor beneath) and the higher ranked prisoners sit on top of stacks based on seniority/ power-level. Newer prisoners were searched for valuables and punishments were meted out.
Conditions were poor inside the prison since the toilet was in the same room. While they received regular visits from a doctor, the care was perfunctory and up to 1,000 prisoners died a year. If you were a new prisoner, you would first meet "the key" a prisoner in charge of prisoners entering and leaving the cell. You would be stripped naked and beaten on the ass with a floorboard or stick to remove any resistance.

Nyujo入定typically means a state of intense meditation however in Shingon Mikkyo Buddhism this describes doing intense fasting & training in order to enter a permanent state of meditation that will last past death.Mummies of people who achieve this state are called Sokushinbutsu. A monk, after committing himself to celibacy and spreading Buddhism, known as Issei Gyojin世行人, will next spend five and a half years reducing his diet from ten different grains, to five and then eventually only to water. This is called Mokujiki-Gyo木食行 “tree food training”

In 1912, the Newspaper carried a vivid account of the Seppuku of the General Nogi Maresuke(1849 –1912) and his wife Shizuko.
The head of the Akasaka Police department said there were many false rumors about the Seppuku of Shogun Nogi and his wife, "Incorrect details regarding the Waripuku (Seppuku) of the Shogun Nogi at the eight o’clock in the evening on the 13th of September (the day of the Meiji Emperor’s funeral). For this reason I would like to tell the truth about what happened in his final moments.”

Women Permit

The Bakufu government wanted to prevent insurrection by controlling the flow of weapons & to watch the movement of the wives and children of Daimyo, since they were required to live in Edo every other year.
Thus up through 1869 permits were required at checkpoints. A Daimyo sending his wife back to his domain might signal the beginning of an insurrection. While all travelers had to have a travel permit, the ones for women were more detailed and the inspections were stricter. For example, they had to define the “type of woman.”

Hyoryu-Adrift: 484 Days at Sea🧵

切腹禁止可然
An argument for the abolition of Seppuku
1869

For crimes committed by Samurai in Japan the sentence of Seppuku is given. However, there are also Samurai that, despite the circumstances of their crime being somewhat ambiguous, nevertheless seek atonement by... ...committing Seppuku. This way of thinking causes the Bumon no Shi, or followers of martial training, in this land to sigh in praise.
