Home to a mind-boggling 13 million people, the metropolitan area of Tokyo is a sensory overload every step of the way. Everything in this mega-city looks, smells, sounds, and feels extraordinary.. like one is in a blockbuster movie, or 15 years in the future. And my first piece of advice for any first-time traveler to Tokyo, is to just let the city swallow you ! Don't even try to make sense of anything, open yourself up to everything.. and don't forget to look up! * Shibuya is known as Japan's fashion center and is where all the cool kids go to drink and party.
