Last month, Yuko Oshima appeared on a special TV programme to mark the 65th anniversary of the end of WW2. The reason for her on this show was because she was meant to represent the youth generation.
Yuko is quizzed about her knowledge of the war. She is given a board with the flags of the main countries that fought in the war and is asked to identify who was in the Axis and Allied Powers. Thing is, young Yuko thought that the UK was on the side of Japan at first which prompted a laugh from one of the other guests on the show. She even paused to think which side China was on as well. Thankfully she corrected herself in the end and got them all right. It really would have been embarassing for her had she not done that. Maybe Yuko got confused about the First World War in which the UK and Japan were allies.
This is a clip of Yuko making that mistake on the show:
