Most snowmen built in one hour
The Iiyama Snow Festival
Japan Iiyama

The most snowmen built in one hour is 1,585 and was achieved by The Iiyama Snow Festival on 15 February 2015

Men, women and children of all ages participated in the event which was part of the annual Iiyama Snow Festival and also to celebrate the opening of the Shinkansen(bullet train) station in the city. Snow was piled chest-high, it was snowing, and the temperature was at a chilly 3°C, but they succeeded through sheer willpower.
