I was on a flight to Japan and there was an interesting movie on someone’s tv. It looked like a futuristic dystopian Japan ruled by the flamboyant upper class who enslaved the lower class. The upper class was dressed in crazy clothes and crazy color pallets(like the hunger games). I think it was about the enslaved lower class rising up against the system. I think I remember a seen were the lower class are in a mine or boiler room(somewhere dark, hot, and dirty). I also think I remember something about it being set in Osaka, and that the city had broken off into its own government. If anyone has any information please help me out.
