Why Did Samurai Borrow from Merchants?

A samurai could receive a rice stipend and still run short of cash. Household bills did not wait for the rice to arrive or find a buyer. Begin with the merchants who collected stipends, sold rice and advanced money against future income. Their customers might outrank them, but lending still meant judging when—and whether—they would be repaid.

At Nihonbashi, the figures in a ledger lead back to boats, markets, porters and shops. Goods arriving by water had to reach buyers in Edo, with payments and deliveries made on time. This is the working city behind the loans: the income a borrower promised to repay depended on other people producing, moving and selling things.

Tanuma Okitsugu sought revenue from a growing commercial economy through arrangements involving licensed trades, overseas commerce and currency. His career shifts the scale from household borrowing to government finance. It also gives us a way to ask who gained from a policy, who faced new costs and how much depended on the officials and institutions around one powerful adviser.

After Tanuma’s fall, Matsudaira Sadanobu pursued thrift, relief and tighter social discipline. The Kansei reforms also intervened in the debts of the shogun’s retainers. Read the two administrations together to see what a change of policy could—and could not—change. Markets and borrowing continued, with competing needs among debtors, creditors and a government trying to manage its resources.

What did it mean to turn rice into money? A coin’s official value, its metal content and the rate offered by a money changer could differ. This optional essay follows the people who issued, exchanged and accepted money. It helps explain why having an income was one problem, and obtaining a form of payment someone else would accept was another.

A samurai could have an income and still lack cash; a merchant could hold a claim and still fail to collect it. Connect Nihonbashi’s trade with the shogunate’s reforms, distinguishing rank, revenue and credit to see why borrowing created both dependence and recurring disputes.
