A wonderful art project by Yuki Tatsumi. “Japanese Tip” is an archive of thousands of paper sculptures made from the sleeves used to wrap chopsticks at restaurants. Having worked as a waiter, Tatsumi noticed customers would often fold the tiny bits of paper into intricate miniature artworks and leave them behind at the table after their meals.

While the custom of tipping doesn’t exist in Japanese culture, Tatsumi took these origamic offerings as a subconscious show of appreciation. In addition to saving the ones he came across on his own, he also reached out to other restaurants to request their “tips.” Tatsumi’s collection includes over 13,000 pieces. A selection of 8,000 was recently exhibited in Tokyo. See more images below or on the website Japanese Tip!
