3. Chopsticks
Chopsticks are one of the most popular souvenirs you can buy while in Japan. They come in so many different designs that choosing just one pair will be impossible. You can find plenty of them in Kappabashi-dori (Kitchen Town) in Tokyo. You can choose between the cheap ones (which break easily) and those of higher quality that cost a little bit more, depending on how much money do you plan on spending on souvenirs.
