Consolidating post offices
Thinking that the samurai class had tilted too far towards learning and leisure, and away from the martial arts and discipline, he frequently issues edicts demanding frugality and self discipline. Under Yoshimune's leadership, the legal and judicial system undergoes considerable expansion.Although the Tokugawa bureaucracy is staffed only by samurai, a non-militaristic and more rational approach is brought to conflict resolution.
In addition, the population of Edo approaches 1 million by 1700 as it developes into the natioinal political center.After 47 ronin kill a daimyō in his Edo headquarters in revenge of their former daimyō's death, they are ordered to commit seppuku.This was an important precedent as it showed that the government now held civil law over the acceptance of military honor.It is estimated that of the 37,000 people who took part, only about 100 escaped alive.Portugese priest and traders are ousted and Portuguese trading ships are banned from the country.Ieyasu assumes the title of Shōgun but still makes a show of deferring to Hideyori.
He installs his eldest son, Hidetada, in Edo castle and moves to Sumpu in Suruga Province (now Shizuoka and where he had been raised as a child - as a hostage).
Among the prohibitions, each daimyō is restricted to the possession of one military castle or garrison headquarters.
In addition, repairs or enlargements could only be made with prior approval from the bakufu and all marriages had to be approved by the shōgun.
The bakufu further limits the emperor's powers by stripping him of the right to select and nominate senior priests.
The bakufu's deputy in Kyōto cancels several already made appointments and Emperor Go-Mizunoo threatens to abdicate, but the bakufu refuses to change the ruling.
As he continues to reassign the daimyō to various fiefs, he is careful to ensure that all tozama daimyō are surrounded, and watched over, by fudai daimyō.
