Also known as: 鯰絵大作戦, namazue
After the 2011 Tohoku Earthquake And Tsunami, Twitter user Semimaru-P called on artists to create namazu-e (catfish-themed Ukiyo-E) to communicate the message, "Pray for no more earthquakes," or "Let's work together not to give in to the earthquake." This project, known as Namazu-e Dai-Sakusen (Operation Namazu-e), was born on Twitter and then earned endorsements on Pixiv.
