Tokugawa Ieyasu created the foundations of Tokyo, and some of his calligraphy remains. You can see it at the Enshu Museum in the Hamamatsu area, where he rose through the ranks. Calligraphy is used to write things like receipts and local rules.
Fine calligraphy like the one pictured is kept in Fukuroi City near Hamamatsu. This is an ancient document called the Shichikajo Josho, and its contents can be summarized as follows.
1. When the lord lives far away, if the distance is less than 5 li, the peasants should carry annual tribute.
2. Regulations for the role of Jinfu. One horse and one foot for every 200 bales. The soybeans used as food for the horses and the rice used to feed the people should be borne by the lord.
3. Annual tax for farmers' residences shall be calculated based on the second of the three rice field grades, Nakata, and 3% shall be exempted.
4. If a feudal lord hires a peasant, he will hire them for 10 days a year, and if he hires a magistrate, he will hire them for 3 days a year.
5. Two Shibuichiyaku (a type of human footy role) should be sent for every 100 kanmon of land survey appraised value.
6. In years of great winds, great floods, and great drought, consider annual tax accordingly.
7. Those who own bamboo bushes must give 50 bamboos each year to Ieyasu and the feudal lord.
It seems that similar policies were implemented in Tokyo as well.This is Japanese calligraphy that you definitely want to see if you are in the area.
