Nagashibina refers to a traditional practice held during Girls Day on the third day of the third month in the lunar calendar in the Yose district of Tottori City in Tottori Prefecture. Pairs of paper dolls — along with flowers and hishimochi (a diamond-shaped red, white and green layered rice cake) — are set afloat in small, round straw boats on the Chiyogawa River, and residents pray for safety and good health.
