A folkloric term for an unexplained loud noise, like a tree falling, heard in forested mountains. Traditionally attributed to tengu felling trees. Used in storytelling and regional folklore.

I heard a story about a mysterious loud sound being heard deep in the mountains.
From 天狗 (tengu, a mythical creature) + 倒し (taoshi, felling). The term comes from the folk belief that tengu cause mysterious tree-felling sounds in the mountains.
