CHIKO'S CHALLENGE The mega-hit entertainment show taking Japan by storm! Culture. Kids. Comedy. Quiz Show. Competition. Chiko's Challenge is a co-viewing comedy show which challenges celebrities with child-like questions which are often surprisingly difficult to answer. The quizmaster is an "eternal 5-year-old" character named Chiko. She is half-CGI, half-costume with the voice of a famous male comedian. Very curious and hard to please, Chiko challenges the celebrity panel with questions like "Why is it slippery on ice?" and "Why do grandpas have long eyebrows?" But be careful! If you cobble together flimsy answers like you do with your kids, Chiko will have a tantrum. Currently one of the biggest studio entertainment shows in Japan. Are you up for a challenge by this cheeky know-it-all?
