Inside a Japanese Flip Flop Factory From raw rubber to finished flip flops. This is how flip flops are made in Japan. Once lost after the Great Hanshin–Awaji Earthquake, Japanese-made flip flops were revived around 2005. Today, they are still crafted in Japan by skilled hands. In Japan, we call them “beach sandals.” Overseas, they are known as “flip flops.” Made in Japan. Crafted with care. #flipflops #madeinjapan #japanfactory #craftsmanship #manufacturing | 株式会社TSUKUMO
