He was born in Edo, the second son of the hatamoto Ogiwara Taneshige. The family was a minor hatamoto house with a stipend of about two hundred bales. The Ogiwara ancestors are said to have been a branch of the Takeda of Kai who served the Tokugawa after the Takeda fell. As a second son who could not rely on lineage, Shigehide would open his own path through skill in calculation and practical work.
As the youngest among his peers, he was added to the shogunate's finance office and permitted his first audience with shogun Tokugawa Ietsuna. The next year he began receiving a stipend of one hundred fifty bales. He seems to have caught his superiors' eyes early as a young man strong in numbers and versed in practical affairs.
The shogunate surveyed the Kinai region, which had not been surveyed for nearly eighty years since the Taikō land survey. Shigehide is thought to have drawn up its detailed plans. To avoid obstruction by local intendants, he had nearby daimyō carry out the survey, sent inspection teams from the finance office and drew up twenty-nine rules to see it through. He was rewarded for this service.
Based on the survey's results, he argued to Tokugawa Tsunayoshi, newly made shogun, and senior officials that hereditary intendants who inherited their posts caused many abuses. In response the shogunate removed the hereditary intendants and changed to a system of appointing intendants as officials. Shigehide's proposal greatly changed shogunal rule.
He was appointed finance inspector, an important post supervising shogunal finances, and his stipend was converted to a grant of land. Having come close to the center of finance while still young, Shigehide faced the difficult task of how to restore the shogunate's household budget in the age of Tsunayoshi, when expenses kept growing.
He was appointed magistrate of Sado and crossed to the island himself the next year. Examining the Sado gold mine, whose output had fallen, he decided to dig drainage channels to remove groundwater pooled in the shafts. At the same time he surveyed the island, greatly increasing the tax yield and using the extra revenue to rebuild the mine, but the heavy taxes angered the farmers.
As gold and silver output fell while the economy grew, money in circulation had become insufficient, and shogunal finances suffered deficits. Shigehide reminted the Keichō gold and silver coins with a lower proportion of precious metal, increasing the quantity of currency. It rested on an idea new for its time: that currency would circulate as long as the government had credit.
He became kanjo bugyo, the official with highest responsibility for shogunal finance, and received the title of governor of Ōmi. The same year the drainage channel of the Sado gold mine was completed, and output recovered for a time. Shigehide strove to increase shogunal revenue by many means, such as raising income from Nagasaki trade and taxing sake brewing.
He carried out a conversion giving land instead of rice to hatamoto who received more than a set amount of rice as stipend. The aim was to cut the cost of transporting tax rice and bring high-yield lands into the shogunal domain. He also pursued practical policies, such as effectively recognizing changes in ownership of pawned fields.
A great earthquake struck the Kantō, damaging Edo Castle and the buildings around it. Shigehide ordered repairs and led the recovery. After that, disasters continued, including the Hōei earthquake from Tōkai to Nankai, the great eruption of Mount Fuji and a great fire in Kyoto, and shogunal expenses only swelled. The hardships of Shigehide, in charge of finances, continued.
When shogun Tsunayoshi died and his successor Tokugawa Ienobu asked about the costs of the succession, Shigehide answered that only recoinage could save the finances. The scholar Arai Hakuseki strongly opposed this, and their conflict began. Hakuseki regarded debased coinage as a national disgrace and repeatedly denounced Shigehide.
Hakuseki went so far as to press that if Shigehide were not dismissed, he would stake his own life against him. Shogun Ienobu, whose illness had grown grave, finally gave way, and Shigehide was removed as kanjo bugyo. Afterward Hakuseki pursued a policy of restoring the coinage's quality, known as the Shōtoku reforms. Shigehide's heir was allowed to inherit only a small domain.
He died the year after his dismissal. It is said he ended his own life by refusing food, but accounts differ. His grave is at Yanaka in Edo. Long regarded as the man who made bad money, he has been reassessed in recent research, which suggests prices rose only modestly after the recoinage, as a figure who anticipated the idea of currency based on credit.
