Complaints choirs are groups of people in different cities who sing about things that are bothering them. It started in Helsinki and has infected ranters all over the world, in St. Petersburg and Philadelphia and Singapore. Tokyo is home one of the newest (and funniest, in my opinion) complaint choirs. In their official music video, seen here, dozens of Japanese people ranging from young women to businessmen in suits sing about everything from screwed up pension plans to unwanted hairs.
