The Tenmei eruption (Japanese: 天明大噴火, Tenmei daifunka) was a large eruption of Mount Asama that occurred in 1783 (Tenmei 3). This eruption was one of the causes of the Tenmei famine. It is estimated that about 1,500–1,624 people were killed in the eruption. The event is known in Japanese as The Burning of Asama in Tenmei (天明の浅間焼け, Tenmei no Asamayake).
