PROBLEM TO BE SOLVED: To reduce time and expenses required for reproducing large-sized snow. SOLUTION: In a large-sized snow-reproducing device that is equipped with a large-sized snow-taking means 1 that takes in large-sized snow where the size of powder snow lying on snow-playing ski slopes as in a ski area is magnified, a large-sized snow transfer means 3 that transfers the large-sized snow that has been taken in, and a large-sized snow fragmentation means 4 that fragments the transferred large-sized snow into the powder snow for emitting, a pin rotor system breaker is used as the large-sized snow fragmentation means 4, where the breaker fragments the large-sized snow and at the same time sucks peripheral chill.
