But the Jōkyō Uprising was unique in that not only the leaders of the uprising (former or incumbent village heads, who did not personally suffer from the heavy taxes), but also a sixteen-year-old girl (subject of the book Oshyun by Ohtsubo Kazuko) who had helped her father, "the deputy ringleader", were caught and executed.
The Mizunos compiled Shimpu-tōki, an official record of the Matsumoto Domain about forty years after the uprising.
Some village heads like Tada Kasuke and Oana Zembei tried to relieve the farmers' suffering by giving away rice from their own storehouses.
The domain lord of Matsumoto was a fudai daimyō, who was obligated to perform many duties, and therefore had to spend a lot of money.
In October 1686, Tada Kasuke summoned a dozen trustworthy farmers to a secret meeting held at a local Kumano Shrine.
After a series of such meetings, Tada Kasuke and his followers came to the conclusion that appealing to the magistrate’s office in Matsumoto was inevitable.
Concerning the part of rice tax collected in the form of soy-beans, half of which is collected in cash; We ask that the tax money be calculated based on the price of rice, not on the price of soy-beans.
Early on the morning of October 14, Tada Kasuke and Oana Zembei, along with their followers,[8] went to the magistrate’s office outside Matsumoto Castle, and handed in the letter of appeal.
But in the process of dramatizing the story of the executed farmers who would later be revered as Gimin, their initial intention was changed into a more peaceful one.
The domain lord, Mizuno Tadanao, was away in Edo for sankin-kōtai (alternate-year attendance) at the time, so the executives had to deal with the situation themselves.
On the night of October 16, the domain government issued a response paper signed by two magistrates.
When the news of the response paper spread, the majority of peasants who had gathered around Matsumoto Castle went home.
Oana Zembei's daughter, Oshyun[12] was responsible for delivering invitations to secret meetings at the Kumano Shrine.
(In addition to the November executions, the new-born son of Oana Zembei's widow, Osato, was sentenced to death.
Matsumoto Castle had been built with a structural defect which caused it to lean, rumored to be due to Tada Kasuke's passionate outcry.
[17] Matsuzawa Kyūsaku, a newspaper journalist from Azumidaira, wrote a play based on the uprising, giving it a title Minken Kagami Kasuke no Omokage (The Image of Kasuke, a Model of the People's Rights Movement).
In 1950, at a construction site near Seitaka shrine in Matsumoto City, a human body was found.
Taking these into consideration, historical and medical researchers of the time concluded that it was highly possible that the seventeen clustered bodies were those of the executed farmers of the Jōkyō Uprising.
Every year on the anniversary day of the executions of the Gimin, a memorial service is held in front of the mound.
[23] The museum, Jōkyō Gimin Memorial Museum, has a plaque with the inscription of the first article of the Universal Declaration of Human Rights, and another plaque with the inscription of the 11th and 12th articles of the Constitution of Japan, in both English and Japanese.
The museum is located right across the street from the former Tada family homestead (designated as a cultural asset of Nagano Prefecture in 1960).
