Tanuma Okitsugu was a highly influential official in Japan during the Edo period. He lived from September 11, 1719, to August 25, 1788. Tanuma served the shogun, who was the military leader of the country. He held two major titles: chamberlain, known as sobashū, and senior counselor, known as rōjū. He served under shogun Tokugawa Ieharu. Along with his son, Tanuma exercised immense power. This influence was most visible during the final 14 years of Ieharu's reign. He was also a daimyō, or feudal lord, of the Sagara Domain.

Tanuma's primary goal was to reform the Japanese economy. He wanted to fix systemic problems in the nation's financial system. Specifically, he aimed to correct trade imbalances. These imbalances existed between the provinces, called han, and the shogun's own lands, called tenryō. The previous shogun, Tokugawa Yoshimune, had used a different method. Yoshimune focused on frugality and agriculture to stabilize the economy. Tanuma chose a more commercial path to achieve his goals.

To manage the economy, Tanuma implemented several complex financial mechanisms. He debased the currency, which means changing the value of the money. He also sold monopoly rights to various dealers. This allowed certain people to be the only ones allowed to sell specific goods. Additionally, he placed taxes on merchant guilds. To stop the outflow of bullion, which is precious metal, he increased foreign exports. He even set export quotas for the Akita copper mines. Copper was the primary metal used for coinage during that era.

Tanuma's administration used monopoly patents to control many different products. These patents were official documents granting exclusive rights to trade. Some of the products included in these monopolies were iron and brass. He also included sulfur, ginseng, and lamp oil. Beyond trade, he invested heavily in infrastructure. He funded massive drainage programs. These programs were designed to drain water from low areas to create more agricultural land. These efforts were meant to increase the amount of food the country could produce.

Despite these intentions, Tanuma's leadership was marked by significant corruption. He was accused of being deeply corrupt himself. His administration also made corruption within the government much worse. This period of instability was worsened by natural disasters. Between 1783 and 1787, Japan suffered several years of crop failures. These failures were caused by severe droughts followed by heavy floods. These weather patterns led to a widespread famine. The lack of food caused frequent riots and peasant rebellions among the population.

Violence also struck Tanuma's family directly in 1784. His son, Okitomo, held the position of wakadoshiyori, or junior counselor. While returning from a meeting of the Counselors of State, Okitomo was assassinated inside Edo Castle. The attack happened in front of Tanuma as they were returning to their norimono, or palanquin. A hatamoto named Sano Masakoto was the assassin. While people suspected senior figures in the bakufu, or government, were involved, only the assassin was punished. This event added to the growing unrest in the country.

Tanuma's political career ended due to a combination of tragic events. The famine caused a spike in protests, including the Edo riots of 1787. Traditionalist opponents of his reforms viewed these troubles as a sign. They interpreted the unrest as the "voice of Heaven" being followed by the "voice of the people." With the assassination of his son and the death of his patron, shogun Tokugawa Ieharu, Tanuma lost his position. His fall from power had lasting consequences for Japan. His economic reforms were halted, and plans to relax the strict rules of sakoku, Japan's isolation policy, were blocked.
