Tokyo Metropolitan Shakujii Park
If you like to people watch, head to one of Tokyo’s many parks on a weekend or holiday. For something more solitary, check ’em out on a weekday. Chances are pretty good that you won’t see anyone other than a few retired folk and/or some pre-schoolers. It may end up just being you, a parked bike, and a sign at Shakujii Park (石神井公園).
