Ienari Tokugawa became the 11th Shogun in 1787 and appointed Sadanobu Matsudaira as a Roju.
A Yoshimune Tokugawa’s real grandson, Sadanobu Matsudaira had the major political reform known as “The Reform in Kansei (the name of a Japanese era)” modeling after the Reform in Kyoho to solve the currency inflation problem which was agonizing the farmers and Samurai financially.
To stabilize both the price and the supply of rice, he made Bakufu and the Domains reserve a certain amount of rice which was to be offered to people in the cases of famines or natural disasters.
Plus, he took such a deflationary policy making Edo citizens save 70% of their income to prepare for the cases of disastrous events.
To enable those farmers who had financially suffered from doing their business and had to come to Edo for a job to go back and to restart their farming business, he had Bakufu financially aid them to do so.
Also, he had Bakufu run the boarding job training center where those who chose to stay in Edo could get their job skills.
He retired from his Roju post in 1793.
