"Zori" is a traditional footwear of which country?

Zori, also rendered as zōri, are thonged Japanese sandals made of rice straw, cloth, lacquered wood, leather, rubber, or—most commonly and informally—synthetic materials.

Similar in form, modern flip-flops became popular in the United States, Australia and New Zealand when soldiers returning from World War II brought Japanese zori with them.

Like many Japanese sandals, zori are easily slipped on and off, which is important in Japan, where shoes are removed and put back on when entering and leaving a house, and where tying shoelaces would be impractical when wearing traditional clothing.

The traditional forms of zori are seen when worn with other traditional clothing. Modern forms are fairly common, however, with casual Western wear, especially in summer.
