Kakigori, shaved ice drizzled with flavored syrup, is a summer staple in Japan. An ice shop in Hirakata, Osaka Prefecture, has been popular for decades thanks to its light, fluffy ice made of "pure ice" that has been slowly frozen. Among the customers were a regular for over 40 years and his children; two university students who will soon graduate and move away; and a mother and son reminiscing about a father who adored kakigori. For three days in summer, we asked customers about what this sweet treat means to them.
