Japan has an aging population with around 25% of the population being above the age of 60 and thus people now work until the age of 80 or 85 and there’s a thriving nightlife for the over 50s where before they might have stayed behind. It is expected that there will be a massive plummet in Tokyo’s population over the next fifty years.
The city’s culture has darkened since the masquerade breaches brought monsters into the limelight and people have reacted by declaring the supernatural ‘technological’ with a firm belief that vampires are ‘ghost hackers’ capable of remote-hacking video capture technology and that fuzzy reflections in mirrors are actually caused by e-screens with video technology masquerading as mirrors. The only real supernatural belief that is taken very seriously by people in Tokyo revolves around actual ghosts and a vampire who blurs, a werewolf who horrifies, or a Changeling that drops the mask will all later be recounted as hauntings.
Japan has acknowledged that the dead walk. It would be foolish to claim otherwise when there is so much going on in America. However, they subscribe to the belief that zombies were the result of a nanotechnology spill in a biotechnology firm in Western America in or around Las Angeles (which is where epidemiologist place the start of the zombie apocalypse). Luckily, the nanites get to work so quickly that any plane that takes off with an infected creature will shortly crash or, in a few cases, be easily quarantined with the pilots safely locked inside the front portion. Several biotechnology companies have confirmed detecting the nanites – which has caused other experts to claim the same lest they appear less technologically savvy.
The Japanese government still retain powers although many politicians are openly, and sometimes covertly, connected to various megacorporations. In theory they are meant to announce any such conflicts of interest but this is rarely the case unless they believe it may earn them more votes as megacorp employees are expected to vote along corporate lines. While they theoretically can’t determine if you haven’t, most people don’t take that risk.
