It is regarded that tanokami (deity of rice fields and harvests) returns to the mountain on this day, and the event involves actions such as children walking around beating the ground with a bunch of rice straws, and people bringing scarecrows back home to thank them for a year's work (which is called kakashi-age).
この日は田の神が山に帰る日とされ、子供たちが藁束で地面をたたいて回ったり、案山子上げをしたりする。
