A peasant revolt that lasted for 18 years broke out in 1771. It was due to the oppression of farmers by the new local governor, Ohara Hikoshiro, who increased taxes (rice) by means of a land survey enforced by the Tokugawa Shogunate. People rebelled against this and directly appealed to the governor himself, only to be rejected. More than 9,000 peasants were severely punished by death or transportation during this period.
