If you dare to litter in Tokyo, you'd better watch out, because there's a team of fearsome samurai warriors ready to admonish you. Every time they make a grand appearance on the streets, onlookers stop to film the warriors, and videos posted online spread like wildfire, with people around the country curious to find out more about the samurai trash collectors. Just last week, they were spotted again, this time inspiring onlookers in Tokyo’s Ikebukuro district with their dramatic fight against litter.
