Where are chopsticks used traditionally and/or on a daily basis?
Chopsticks are used in Japan, China, Korea,… The Japanese call them “hashi” (or sometimes “ohashi.”) The disposable chopsticks are called “waribashi” and chopsticks rests are called “hashi-oki.” Chopsticks are called “Kuai Zi” by the Chinese. In Korea, chopsticks are called “jhuk kha rak”, and are usually made of metal. I believe chopsticks are frequently used in Vietnam as well. Chopsticks are not used in Thailand. Filipinos traditionally eat with their hands.
