Every March 3, Japan observes Hina Matsuri, or Girl’s Day. In shrines around the country, tiered displays of dolls are set up, modelling an imperial court in Kyoto from Japan’s Heian Period of the 8th-11th centuries. Parents with daughters also set up smaller displays in their homes. In the city of Mochigase in Tottori Prefecture, the dolls are arranged in small boats and set to drift down the river.
