Edo period
Agriculture

Rice was the base of the economy. About 80% of the people were rice farmers. Rice production increased steadily, but population remained stable, so prosperity increased. Rice paddies grew from 1.6 million chō in 1600 to 3 million by 1720. Improved technology helped farmers control the all-important flow of irrigation to their paddies. The daimyo operated several hundred castle towns, which became loci of domestic trade.

Large-scale rice markets developed, centered on Edo and Ōsaka. In the cities and towns, guilds of merchants and artisans met the growing demand for goods and services. The merchants, while low in status, prospered, especially those with official patronage. Merchants invented credit instruments to transfer money, currency came into common use, and the strengthening credit market encouraged entrepreneurship. The daimyo collected the taxes from the peasants in the form of rice. Taxes were high, often at around 40%-50% of the harvest. The rice was sold at the fudasashi market in Edo. To raise money, the daimyo used forward contracts to sell rice that was not even harvested yet. These contracts were similar to modern futures trading.

It was during the Edo period that Japan developed an advanced forest management policy. Increased demand for timber resources for construction, shipbuilding and fuel had led to widespread deforestation, which resulted in forest fires, floods and soil erosion. In response the shōgun, beginning around 1666, instituted a policy to reduce logging and increase the planting of trees. The policy mandated that only the shōgun and daimyo could authorize the use of wood. By the 18th century, Japan had developed detailed scientific knowledge about silviculture and plantation forestry.
