>>279922803I think there are two main factors that determine which eras get written about.
Any era one generation beyond living memory has a certain mystique because it feels recent enough to be real, but distant enough to romanticize without readers calling your bluff. Currently, that's the Meiji and Taisho eras.
Any era within living memory that writers and readers are nostalgic for can be romanticized because both parties agree on what they want to get out of the fictional portrayal even if they know it wasn't like that in reality.
The post-war period probably occupies an awkward spot inbetween where no one who lived through it remembers it fondly and no one who didn't live through it wishes they did.
