I have 2 friends who do very small origami cranes, the girl got so many people sitting next to her in the train to start a convo and would give them on dates I think it made her stand out one time a girl asked her out on the train after giving her a crane. The guy left them all over the study halls of his uni and now he's sort of a legend, people started recognising him, I don't know if he got dates but he's denser than anyone I know! (I do not live in Japan btw)
