LONDON (Reuters) – From samurai armour to a folding screen depicting Mount Fuji, dozens of Japanese artifacts from the British royal collection go on public display in a new exhibition at the Queen’s Gallery near Buckingham Palace. “Japan: Courts and Culture”, which opens on Friday, features more than 150 items, including gifts from Japanese emperors to Queens Victoria and Elizabeth. “‘Japan: Courts and Culture’ tells the story of 350 years of artistic and diplomatic exchange between the courts of Britain and Japan,” exhibition curator Rachel Peat told Reuters at a media preview on Thursday. “…
