Many tourists who come to Japan from abroad buy traditional Japanese chopsticks. Since I work for a foreign-affiliated company, I sometimes go sightseeing in Tokyo with many foreigners, and they buy chopsticks.
Then, they are asked about how to use and manners, but when asked about Japanese people, they find it ambiguous and reconfirm about chopsticks and manners.
Chopsticks are not only used in Japan, but also widely used in East Asia. In Japan, wood or bamboo is used as the material, but in other countries in East Asia, some are made of metal or ivory. Recently, many plastic products are found regardless of the country.
