The Yōwa famine (養和の飢饉, Yōwa no kikin), was a famine which affected Japan at the end of Heian period. It began in 1180, and lasted until 1182. It was named after the Yōwa era (1181–1182), during the reign of Emperor Antoku. The shogunate system was not established in Japan yet. The famine was most severe in central and western Japan (especially Kinai) and caused by an alternating, untimely drought and flood.
Why this event still matters
Historical incidents shape the rules that protect people today — building codes, evacuation policy, warning systems and inspection regimes almost always trace back to a specific disaster. Studying Yōwa famine alongside current events is how preparedness improves.
