I thnik the current title Hirohito is more apropriate to an English not Japanese Wikipedia Pratically nobody outside Japan calls Hirohito Showa  even the Popes cannot be used as example because even nonCatholic people refers to them as their ecclesiastic names that they get before they die To bow our heads to respect Japanese traditions and rename the article to Showa is a repression of the freedom of speech in the name of political correctness  if people thought the same way the image on the Mohammed Cartoons article should be deleted too
