- Date: 1732
The Kyôho famine, brought on by hordes of locusts, struck the Seto Inland Sea region and Kyushu in 1732, causing rice prices throughout the region to increase by a factor of seven. Roughly 22% of the population of Fukuoka han, or 70,000 people, died due to the famine; among certain classes and communities, the proportion was as high as 45%. Fukuoka's population did not recover to pre-famine levels until the Bakumatsu period.
