Flip-flops were created after the war by Americans inspired by Japanese geta and zori sandals, and were initially manufactured in Hyogo Prefecture, which had a thriving rubber industry.

Leather flip-flops that could withstand long-term use rather than being disposable were developed in California in the 1970s, where the blue skies are perfect.
