It’s a dream city, Tokyo. I mean that literally, in that I often felt like I was experiencing it while asleep. You’ll ride an escalator underground into what your map says is a tunnel between subway stops, only to find yourself in a thumping subterranean mall packed with beautiful teenagers dancing to Katy Perry remixes. You will take a turn off a busy street and into a deserted Buddhist graveyard, soundless but for the wind and the clacking of sotoba sticks, wooden markers crowded with the names of the dead. You will stand in a high tower and look out on the reason-defying extent of the city, windows and David Beckham billboards and aerial expressways falling lightly downward, toward the Ferris wheel on the edge of the sea.
