Emperor Kōkaku
The Great Tenmei famine (天明の大飢饉, "Tenmei no daikikin") was a famine which affected Japan during the Edo period. It is considered to have begun in 1782, and lasted until 1788. It was named after the Tenmei era (1781–1789), during the reign of Emperor Kōkaku. The ruling "shoguns" during the famine were Tokugawa Ieharu and Tokugawa Ienari. The famine was the deadliest one during the early modern period in Japan.
