What is it about Tokyo that can make visitors feel as if the city belongs not in another country, but on another planet? Perhaps it’s the schizophrenia at the heart of what was once Edo—stately, tree-lined Omotesando giving way to the pinball frenzy of Shibuya, Tomorrowland Shinjunku meeting the timeless Meiji Jingu shrine. Tokyo contains multitudes, which we mean literally—the metro are is home to more than 35 million people, and on a muggy day in August you can feel nearly every one of them. Forget about navigating above ground—even the taxi drivers are dependent on GPS. But there is truly no other place on Earth—or elsewhere—like it, and those who can endure the over-stimulus will find themselves drawn back again and again.
